How to cut Sentifier panels for window slopes. Positive qualities of the material

How to cut a sandwich panel. Variants of window slopes

The traditional method of finishing is of course plaster. If such work is performed by a qualified specialist, then for many years you can forget about the repair of slopes. An important point when choosing this method is the lack of the need to install a plastic corner at the border of the slopes and walls.

The choice of such a method is justified in the first place if the wall in which the window is located is also leveled by plaster. But, given that when the slopes are removed, the plaster layer reaches 5-7 cm. and more, it is necessary to install a reinforcing grid. Only a master can do qualitatively such work.

I was not satisfied with this option because the wall is a framing window, it was made of drywall, and in addition, a countertop was already installed, which played the role of the windowsill.

As an alternative, three options were considered. Finishing the slopes of the window using drywall, followed by painting, slopes of drywall with plastic plastic and the use of sandwich panels on its surface.

Now the option with painting slopes from drywall is used only with budget repair of non.residential premises. Plastic glued on the basis of drywall. a variety of the same economical option.

Temperature changes, as well as high humidity, quickly destroy drywall. Perform restoration repair every 2-3 years-not our method. Therefore, we opted for PVC sandwich panels.

Sandwich panel is 10 mm. The sandwich consisting of two PVC sheets between which is located a heater made of polystyrene foam. The only inconvenience when buying is the need to acquire a whole sheet of 3000×1500 mm.

There are no difficulties in working with him. it is easily cut by corner grinding and even an ordinary knife (if necessary, grossly cut into pieces for climbing the apartment).

Installation of sandwich panels. Installation of sandwich panels: step-by-step instructions

The sandwich panels were invented in the 30s of the last century, but are still highly popular in housing and industrial construction around the world. This is a practical, inexpensive and durable material that combines the quality of the insulation, noise and waterproofing, as well as exterior decoration. In this article we will talk about the varieties of sandwich panels and installation methods.

Characteristics of sandwich panels

Sandwich panels are made in specially equipped factories in an exclusively mechanized way. They consist of several layers, representing a kind of “sandwich” or “sandwich” (hence the name) from various building materials.

A thermal insulation material of various quality is placed between the metal sheets. The thickness of the sandwich panels depends on the insulation, it also determines the cost of the product. This parameter is also affected by the thickness of the metal shell.

For the construction of the roof, thin panels with sheets of 0.6 mm are usually used, and more massive are used for wall cladding. with a sheet thickness of up to 1.2 mm.

The sizes of sandwich panels also affect pricing. The standard product reaches 12 m long, but at the request of the customer this parameter may change.

The total thickness, taking into account metal sheets and insulation, can be 40-250 mm. The width of the panels depends on the profile and is from 50 to 120 cm.

Narrow products are mainly used for the construction of garage gates, and wide. for the construction or decoration of all kinds of objects (warehouses, houses, garages, etc.D.).

The most expensive. three.layer sandwich panels. This is due to a more complex structure, high strength and better characteristics.

Advantages and disadvantages

Such many years of popularity of sandwich panels is explained by a mass of advantages and advantages in relation to other materials.

  • Fast installation. the construction of walls or cladding with panels does not take much time;
  • The small weight of the products. a relatively light design does not require financial costs for the construction of a durable foundation that would be needed, for example, for a brick or concrete box;
  • Structures from panels can be upgraded over time, disassembled and transported to another place;
  • Savings. to build a house from sandwich panels is several times cheaper than from brick or blocks;
  • Fire safety. the heat.insulating layer is reliably protected from exposure to direct flame with metal sheets. The exception is a sandwich panel with PVC, polyurethane foam or polystyrene foam in the middle, so carefully study the composition;
  • Environmental friendliness. in production, materials safe for health and nature are used;
  • High strength. wall sandwich panels are made of thick metal sheets resistant to mechanical damage;
  • Thermal insulation. this parameter depends on the thickness of the insulation in the “sandwich”;
  • noise insulation. the thicker the panel, the better it protects against extraneous sounds;
  • You can mount a sandwich panel at any time of the year, except winter with fierce frosts (icing may appear at the joints).

Sandwich plastic windows finishing with panels. Properties of the material

The device of standard panels looks like a sheet, the outer side of which is a whole.leaf PVC, the internal. sheet polystyrene, in the middle is a heater. That is why this option was called an American word. a sandwich panel.They are different onyly with the material of the facing side, and the installation remains the same for any kind.

Important! The people of the slopes of the sandwich call. warm slopes. This is due to the insulation, which is present in the panel

When you have already imagined what it is, I will tell you about their advantages:

  • Despite their popularity, they remain accessible to all due to their acceptable price.
  • This is not just a construction element, it is still an independent device that has its own configuration.
  • The internal place is filled with mineral wool or foamed polystyrene. this indicates a non.combustible structure.
  • Excellent heat insulation indicators, as well as additional sound insulation is achieved with their help.
  • This method of decoration is durable and durable.
  • If you perform installation with your own hands, then you must definitely follow the installation technology. In this case, resistance to moisture and mold will be at a high level.

For those who decided to change the windows in their house or apartment, and set the slopes with their own hands, I will give advice: you need to wait at least 24 hours after installing windows and only then finish the slopes of the sandwich with panels. The advantage of installing a sandwich over plaster is that installation hands do not require painting skills and is a pure way.

It is important not only the correct installation of slopes, but also what to cut the panels. Plastic elements are best cut with a disc circulatory saw on plastic or aluminum. In this case, a small step of the teeth is able to perfectly cope with the task. In addition, it is necessary to cut the material at a temperature of 5 degrees Celsius-if you do not observe the temperature regime, then chips on the cut line may appear due to a decrease in shock viscosity. If there is a pvc sandwich sloping, then you can cut with many tools. But the most optimal hacksaw for metal remains, it is possible on wood. Cut the front side up and with a small angular slope. At your own peril and risk, you can cut a corner grinder, but having a little overdo it with pressure, the panel may break.

Products from sandwich panels

With your own hands, installing plastic slopes can be performed using multilayer material covered with decorative plastic on both sides. By installing slopes from plastic with your own hands using sandwich panels, you can not produce additional thermal insulation.

Sandwich panels have high thermal insulation properties

Installation of PVC slopes when using this material occurs quickly and with a minimum amount of garbage. The use of slopes from PVC panels of this type provides protection of the window from freezing.

Sandwich panels have the following characteristics:

  • PVC provides reliable heat and sound insulation;
  • The decoration of window slopes with this material increases the energy efficiency of the window system as a whole;
  • If you make slopes from the panels correctly with your own hands, then the window opening will gain a neat appearance;
  • Do.it.yourself window decoration with your own hands is performed quickly and efficiently;
  • even an unprepared person can make slopes of plastic with insulation.

Mounting

A sandwich panel can be attached as well as PVC panel. How to make such a finish yourself, shown below.

How to finish the slopes of windows with plastic without a starting profile step by step, shown below.

  • This installation method is relevant at a small distance from the frame to the opening, when the starting profile is simply nowhere to mount;
  • excess foams are carefully removed. A thin rail is attached to all sides of the opening; In this case, the panel is installed in foam by 1 cm, so the latter is cut accordingly around the entire perimeter;

Installation of sandwich panels is carried out in the groove in the mounting foam first inserts the upper part into the resulting groove. A little bends, and the resulting space is covered with a small amount of mounting foam; The panel is mounted with self.tapping screws to the rail;

How to cut plastic panels. How to cut PVC panels

This operation can be performed by many tools, however, the most common solution is various types of hacksaws: on wood, metal. We recommend paying attention to the hacksaw of the vira brand. They are ideal in price/quality ratio. The most popular because it significantly saves time if necessary to prepare several panels of the same size, you can saw several pieces at once. The cut is carried out strictly with the front side of the panel upward, slightly holding it under the slope. It is recommended to squeeze the panel for stability, but in no case should you strongly squeeze it.

In the case of a hacksaw on wood, it is recommended to use the teeth of the transverse or mixed sawing. The thing is that they leave a very even, without a zabrin section, after which additional processing of the sawn surface is most often not required.

However, how to cut off the PVC panel if there is no hacksaw? It is quite possible to use an electric jigsaw. However, in this case, it is worthwhile to carefully monitor the pressure of pressure so as not to break the panel.

And if there is nothing at all at hand, and you need to do work right now than cut off the plastic panel? You can use a knife, it is desirable that it be a special construction knife, but for lack of one, a very sharp household, hunting knife is suitable. An ordinary stationery knife is also good, but it is necessary to cut it very carefully, since it is quite fragile and sharp. In this case, it is necessary to mark the fishing line for the trimmer on the panel, according to which it is supposed to make a section. Then, along the ruler (if the fishing line for the trimmer should be straight), a deep incision is made by the clerical knife strictly along the line, after which the panel breaks. If the fishing line for a trimmer should be with bends, it is impossible to break in any case, since the panel will simply break, the material will be spoiled.

How do professionals cut wall panels? There is no definite answer, since, depending on the type of plastic and the panel, upcoming work, one or another tool is selected. For example, it is easiest to cut it in a straight line with a hacksaw, but it is better to cut the bends with an electric jigsaw, or if it is not, with a construction knife.

Installation of sandwich panels. Recommendations for the use of panels

Sandwich panels can be fixed horizontally, which is most often practiced and vertically. In the first case, the installation begins from the foundation of the construction, in the second. from the corner of the structure.

Vertical installation of material, as a rule, is used to install structures up to 6 m high. You cannot combine two installation methods.

Several important requirements when working with multilayer material.

  • Unloading is carried out one package using a crane or fork loader.
  • Packs need to be placed on a flat surface (installing on each other is prohibited).
  • The panels for convenience are installed next to the work site.

Installation of panels to the frame or base is carried out using special self.cutting screws made of hardened steel. Fastener must have a sealing puck. The type of metizes is determined in accordance with the type of supporting structure and its thickness. It can be made of concrete, wood, brick or metal.

#Shorts. Cutting into a upvc window frame. Cut in tips.

Before installing the panels on a metal or wooden base, it is necessary to drill holes for installation in advance, but when using self.hinging screws, this stage will not be needed. The length of the fasteners depends on the thickness of the panel and varies from 85 to 235 mm. Most often used parts with a diameter of 5.5 mm.

To fix the material to concrete, the preliminary device of the holes is mandatory. over, both in panels and in the base. Products are attached by installing dowels.

  • From the edges of the material, the fasteners should be at a distance exceeding 5 cm.
  • The installation of metizes should be carried out strictly perpendicular to the outer layer of the panel.
  • An important point that largely affects the quality of installation is the correct tightening of fasteners. Self.tapping screws with a sealing puck should be twisted to complete contact with the base. In this case, excessive screwing should be avoided, which over time can lead to depressurization of the compound.

For installation, you will need clamps to support panels until they are completely fixed. To cut the material, you can use saws (circular or tape), jigsaw, electric knights for metal. In this case, the corner grinder is not used in this case, since the temperature effect that occurs during the operation of this tool leads to damage to the material.

for inexpensive sandwich panels

Before starting work, it is necessary to check the ends of the products. The insulation should not act. Otherwise, this defect must be eliminated. It is necessary to apply waterproofing to the upper part of the base.

Cons and pluses of slopes from sandwich panels

The main advantages and disadvantages

The specified type of slopes is performed using mounting foam. high.quality sealant on a polyurethane basis. The material is distributed in the center between two small sheets from the PVC structure.

Among its main advantages, the following are distinguished:

  • No additional processing and decoration of the surface after installing the slopes is not required, because the plane is characterized by a structure that is exactly similar to metal.plastic products.
  • Drywall over time is subject to cracking and wetting under the influence of moisture presented in the form of condensate. Sandwich panels for window slopes always remain waterproof and do not destroy.
  • If the insulation of sandwich panels is needed, then this is more likely in the measures of reinsurance, because the material does not miss the cold at all. Experts often carry out such measures with the aim of immobilizing and strengthening the design on the window.
  • Cleaning the sandwich panel is not difficult, a rag moistened in soapy solution, dust, dirt and even coffee spots are rubbed. If this has not helped, it is allowed to use the detergent that is usually washed, but without the presence of abrasive substance.
  • The installation is reduced to a simple and understandable procedure, thus, even a beginner in construction will be able to cope with the installation.
  • The life declared by the manufacturer ranges from 15 to 20 years. The slopes are not afraid of hail, strong wind and rain.

It’s time to discuss the minuses of sandwich panels. Rather, they are associated with the low quality of the proposed material, so when buying, pay attention to the manufacturer, do not be afraid to ask the seller-consultant inconvenient questions and demand to show certification.

Turn to the quality of the panel material

This is in your interests, because low.quality panels under the influence of sultry weather and high temperatures acquire a yellow tint, which cannot be eliminated and deformed, therefore they are considered extremely unreliable and brittle.

Much depends on the diligence and responsibility of the one who set to install the slopes from the sandwich panels. A careless attitude, haste and mismatch of the installation technology can subsequently lead to the formation of voids between panels and the windowsill.

Sandwitch slopes device

Studying the device of the internal structure allows us to conclude that slopes from sandwich panels are very similar to the usual plastic. If you pay attention to the functional component of these two copies, then you will understand that their technical characteristics are also identical.

To make slopes from sandwich panels with your own hands, you will have to collect a few components of the product into one, namely:

  • Profile made of plastic, presented in the P-shaped form. Its other name is the starting profile, because it is from its installation that the installation of the device originates. Fixation occurs directly around the perimeter of the window box, creating the right connection of the slopes with each other and with other important windows of the window.
  • A sandwich panel is a composite where polyurethane or polystyrene is located in the center between the plates made of plastic. The thickness of the panel can be very diverse. from 10 to 32 mm inclusive. Which model is suitable in this particular case depends on the free area coming from the edge of the window box to its end. Experts recommend using a universal device, the thickness of which is 24 mm.
  • Platband-plastic profile taking F-shaped. The difference from the starting profile is that the platband additionally has a protruding wide part, blocking the joint, which forms during the installation of the structure between the sheet and the angle of the window, which is located on the outer side.

Masters use other methods of arranging sandwich panels. In most cases, brackets fixing the front of the panel due to the attachment of platforms from the type of rail are used. This type of slopes is called European, and the assembly process is more like a designer that allows you to turn the installation of slopes from sandwich panels into a light and fast procedure.

How to cut windows for windows. Installation of corners on window slopes or doors

Having dealt with what such products are made of, what are their features and having decided on the choice, you should study how to install corners on slopes. Detailed instructions are given below.

What glue to use

In addition to the corners themselves, we will also need an adhesive with which we will attach the selected element. When choosing it, it is worth remembering that quite often, especially if it is necessary to glue a narrow product, the glue seeps from under it and, of course, falls on the walls. As a result of this, the latter can be damaged, which, accordingly, will negatively affect the appearance of the room as a whole. Therefore, you should choose such an adhesive composition, the excess of which can be removed from the surface.

Basically, the corners are glued to new slopes, but nevertheless, check that the surface is relatively flat, since no decoration will be able to hide large hillocks. It should not have foreign objects like nails, screws, etc. D. It also needs to be degreased, for this purpose, white spite.

How to cut it correctly

Before discussing how to fix the corners on slopes, you should find out how to cut them correctly. After all, this stage of everything is the most time.consuming and, perhaps, even the most important, since it depends on how their edges will joke, and this directly affects the aesthetic appearance of the entire room. It is best to cut with a hacksaw with a small tooth. First you need to measure the length of the opening, then apply the marks to the corner so that the segment corresponds to this parameter. Then the part that will fit directly to the slope is cut strictly according to the marks, and the one that to the wall is at an angle of 45 °.

To cut the corner, use a hacksaw with small teeth

How to glue

Finally, we got to the main question of how to stick corners on slopes. However, before proceeding directly to fixation, it should be carried out, so to speak, fitting. After making sure that everything is cut correctly, you can move on. Apply to the inside of the corner, at the junction of the sides, gluing a solution with a step of approximately 10 cm. At this stage, an indispensable assistant will be a mounting gun. After that, quickly press the product to the surface and fix it in this position with a painting tape. You should start with a horizontal slope, and then proceed to the side. Remove the excess sealant from the surface of the walls with a damp cloth and let it dry well. You can remove adhesive tape only after 24 hours.

How to build slopes from sandwich panels

First of all, we will figure out what are the slopes and why they are needed. The slopes are called the inner walls of the niche, which is located in the window box. The installation of the window itself is not a complete process if additional manipulations are not carried out, which in most cases include plastering, putty and, if necessary, painting the structure.

Popular in modern times, PVC-editions also require appropriate insulation, which is represented by slopes and material-assuming material located inside.

Is it possible to avoid buying thermal insulation materials? It is possible, for this it is enough to consider slopes from sandwich panels, which will not only provide the premises with a warm temperature regime, but also give the window a complete appearance. The last parameter is also important, because the neat type of window frame affects the design of the room directly and creates a certain opinion about the owner of the apartment or private house.

Subtleties and nuances of work

To ensure the evenness of the incision (and therefore the correct geometry of the cut part of the wall or roofing sandwich panel) should be known to know several rules:

  • The sandwich panel should be securely recorded before cutting;
  • The marking should be clearly visible;
  • cutting always begins with the outer layers;
  • cutting the inner layer is carried out by a thin tool;
  • It is possible to use corner grinder or other “high.speed” cutting devices only in exceptional cases: there is a great risk of both fire and damage to the protective coating.

Wall sandwich panels and some features of their installation

To make it easier to understand the technology of installation of wall panels, we suggest you familiarize yourself with step.by.step instructions and photom meters.

And now, having dealt with a step.by.step explanation of the order of action, it is worth noting the nuances inherent in each of the stages of installation

Features of raising sandwich panels using a crane

The main task with the clamp of the panels with clamps with eyelets is not to pull the screws, and, at the same time, do not leave them weak. In the first case, the metal will be predicted, which will lead to a violation of the tightness of the joints of the facial layers. This means that water will seep inside, impregnating the insulation and destroying it. In the second case, with a puff too weak, the panel can simply slip off when lifting, which is very dangerous not only for health, but also for life.

Longitudinal joints should be perfectly fitted. As for transverse seams, a small discrepancy is allowed here, which will subsequently be closed with inputs (style elements).

Sandwich panels are quite diverse

Fastening sandwich panels to the frame

When fixing elements, the screws should not be pulled. This will lead to dents, which means that the inhibits simply will not be able to close the cracks tightly.

How To Install A Window (New Construction)

Slopes from sandwich panels. Facing window slopes with sandwich panels

Sandwich-panels decoration of window slopes.

Different finishes are used to facing the window opening inside the house. Not so long ago, the choice of finishing materials was limited to plaster and drywall. Today, sloping panels are considered one of the most common decoration options.

Why are slopes needed

The finished window slopes hide the mounting seams and give accuracy to the appearance of the window and the completeness of the aesthetics of the interior

Advantages of sandvich finish with panels over other types

Before possible types of slopes of slopes, the sandwich panels have the following advantages:

  • ensuring the optimal insulation of the cold walls of the opening from the microclimate in the room, which is impossible to achieve if you make a window soda from GKL;
  • a decrease in the noise level in the room, when plastering slopes, is not about any insulation of heat and noise;
  • improvement of illumination thanks to the reflective surfaces;
  • the low weight of the finishing material is less than 2 kg/m2 versus 10 kg/m2 of gypsum plasters with the same thickness;
  • the possibility of a solid connection to the PVC frame, which cannot be achieved by plaster slopes;
  • Inappropriateness of temperature changes and direct sunlight, so such slopes are suitable not only for windows, but also for doors;
  • the impossibility of cracking, while cracking of a plastered window slope is not uncommon;
  • the lack of the need for surface processing with putty, unlike gypsum cardboard finishes (there are no wet finishing work);
  • carrying out installation work with a minimum amount of construction waste, which cannot be imagined when using GCL or plaster;
  • the ability to use detergents to remove pollution, which simplifies the care of the sloping surface.

The composition of the panels

Sandwich sheets are made of extruded polystyrene foam 0.9 cm thick. Products can be decorated with PVC on one or both sides. The size of the panels for windows. 150 by 300 cm. The composition contains the following materials:

  • A wood border that is a leading.
  • Upper panel playing the role of decorative decoration.
  • Different in form profiles, C-shaped products are installed from the side of the room. A special J-shaped element is needed for attaching the internal border.
  • Polystyrene insulation, which fill all the cavities. Due to this design, they do not allow the cold to penetrate the room.

For insulation, foamed plastic, polyurethane foam, and extruded polystyrene are used. The outer layer can be made of these materials:

  • Multilayer plastic. For its manufacture, resin is impregnated with layered material, which consists of a pressed craft paper.
  • Sheets of hard PVC. For the production of sandwich, white sheet material is used, the thickness of which can vary from 0.8 to 2 mm. A special external coating is both matte and glossy.
  • Sheets of foamed plastic. The material inside is porous, has high thermal insulation indicators.

To date, a wide color scheme of products is presented in construction stores, which makes it possible to choose a shade in the tone of the window. It should be noted that the sandwich for windows can be in the form of a finished system. In this case, no preparatory work on the assembly of the design is required. Products are fixed to the slope using a special adhesive mixture. The second option involves the assembly and fixation of the panel using self.tapping screws.

The panels can be one- or bilateral. In the latter version, all parties are considered facial. Some tend to think that sandwich can only be used for plastic window structures, but it is permissible to install them on wooden windows. One.sided structures suggest that one side is external, and the second internal. The front part is a little thicker than the rough. It is important to understand that the installation of sandwich panels for slopes of PVC windows is very important for a number of reasons:

  • Products prevent the formation of condensate and moisture;
  • thermal insulation characteristics improve;
  • The seams are protected from destruction.

Installation of sandwich panels. Installation of sandwich panels: step-by-step instructions

The sandwich panels were invented in the 30s of the last century, but are still highly popular in housing and industrial construction around the world. This is a practical, inexpensive and durable material that combines the quality of the insulation, noise and waterproofing, as well as exterior decoration. In this article we will talk about the varieties of sandwich panels and installation methods.

Characteristics of sandwich panels

Sandwich panels are made in specially equipped factories in an exclusively mechanized way. They consist of several layers, representing a kind of “sandwich” or “sandwich” (hence the name) from various building materials.

A thermal insulation material of various quality is placed between the metal sheets. The thickness of the sandwich panels depends on the insulation, it also determines the cost of the product. This parameter is also affected by the thickness of the metal shell.

For the construction of the roof, thin panels with sheets of 0.6 mm are usually used, and more massive are used for wall cladding. with a sheet thickness of up to 1.2 mm.

The sizes of sandwich panels also affect pricing. The standard product reaches 12 m long, but at the request of the customer this parameter may change.

The total thickness, taking into account metal sheets and insulation, can be 40-250 mm. The width of the panels depends on the profile and is from 50 to 120 cm.

Narrow products are mainly used for the construction of garage gates, and wide. for the construction or decoration of all kinds of objects (warehouses, houses, garages, etc.D.).

The most expensive. three.layer sandwich panels. This is due to a more complex structure, high strength and better characteristics.

Advantages and disadvantages

Such many years of popularity of sandwich panels is explained by a mass of advantages and advantages in relation to other materials.

  • Fast installation. the construction of walls or cladding with panels does not take much time;
  • The small weight of the products. a relatively light design does not require financial costs for the construction of a durable foundation that would be needed, for example, for a brick or concrete box;
  • Structures from panels can be upgraded over time, disassembled and transported to another place;
  • Savings. to build a house from sandwich panels is several times cheaper than from brick or blocks;
  • Fire safety. the heat.insulating layer is reliably protected from exposure to direct flame with metal sheets. The exception is a sandwich panel with PVC, polyurethane foam or polystyrene foam in the middle, so carefully study the composition;
  • Environmental friendliness. in production, materials safe for health and nature are used;
  • High strength. wall sandwich panels are made of thick metal sheets resistant to mechanical damage;
  • Thermal insulation. this parameter depends on the thickness of the insulation in the “sandwich”;
  • noise insulation. the thicker the panel, the better it protects against extraneous sounds;
  • You can mount a sandwich panel at any time of the year, except winter with fierce frosts (icing may appear at the joints).

How to cut plastic panels. How to cut PVC panels

This operation can be performed by many tools, however, the most common solution is various types of hacksaws: on wood, metal. We recommend paying attention to the hacksaw of the vira brand. They are ideal in price/quality ratio. The most popular because it significantly saves time if necessary to prepare several panels of the same size, you can saw several pieces at once. The cut is carried out strictly with the front side of the panel upward, slightly holding it under the slope. It is recommended to squeeze the panel for stability, but in no case should you strongly squeeze it.

In the case of a hacksaw on wood, it is recommended to use the teeth of the transverse or mixed sawing. The thing is that they leave a very even, without a zabrin section, after which additional processing of the sawn surface is most often not required.

However, how to cut off the PVC panel if there is no hacksaw? It is quite possible to use an electric jigsaw. However, in this case, it is worthwhile to carefully monitor the pressure of pressure so as not to break the panel.

And if there is nothing at all at hand, and you need to do work right now than cut off the plastic panel? You can use a knife, it is desirable that it be a special construction knife, but for lack of one, a very sharp household, hunting knife is suitable. An ordinary stationery knife is also good, but it is necessary to cut it very carefully, since it is quite fragile and sharp. In this case, it is necessary to mark the fishing line for the trimmer on the panel, according to which it is supposed to make a section. Then, along the ruler (if the fishing line for the trimmer should be straight), a deep incision is made by the clerical knife strictly along the line, after which the panel breaks. If the fishing line for a trimmer should be with bends, it is impossible to break in any case, since the panel will simply break, the material will be spoiled.

How do professionals cut wall panels? There is no definite answer, since, depending on the type of plastic and the panel, upcoming work, one or another tool is selected. For example, it is easiest to cut it in a straight line with a hacksaw, but it is better to cut the bends with an electric jigsaw, or if it is not, with a construction knife.

Correct slicing sandwiches and the choice of tools

But with all its undeniable advantages, sandwich panels have one serious drawback: they are extremely demanding on mechanical processing. Plastic sheets are very fragile and is easy to damage them in any careless movement. Foamed polystyrene is a fairly viscous material that requires a lot of effort during its mechanical processing.

And the surface of the window slopes is such that the sheets of sandwich panels should be cut to give them the necessary sizes. To do this, it is best to use an electric jigsaw, ultra.suffering movements of its cutting blades create an uniform force under which fragile plastic and viscous polystyrene are carefully cut. Another advantage of an electric jigsaw is an opportunity to create curved cuts.

The only drawback of this tool is that not every owner is found.

Unlike the same corner grinder, which is necessarily found if not with you, then your symbolic or neighbors for sure. But there is one difficulty. During cutting, the corner grinder should be kept by weight. Since this tool has a fairly large weight, it itself, even with a not very strong press, can damage fragile plastic.

Finally, for cutting, you can use a hacksaw for metal, but with this method the likelihood of cracks and chips due to the emerging resonating vibrations increases significantly, and as a result you will get uneven edges of the cut.

Therefore, if you do not have an electric jigsaw or corner grinder at home, then it is best to entrust this procedure to a professional who has the necessary power tool in the presence. Or you can take the instrument for rent, but in the current conditions it will cost you dearly.

For window openings, two- and three-layer sandwich panels are used. The former are made of decorative plastic, to the reverse side of which on an adhesive base is fixed a thermal insulation layer of foamed polystyrene. In the second, decorative plastic closes the thermal insulation layer on both sides. As a result, three-layer sandwich panels are greater, which is why they preserve their shape better.

Note that decorative plastics are made in any color scheme, as well as in imitation of various textures of facing materials (wood, stone, etc.P.). The foamed polystyrene has almost zero thermal conductivity, which is why condensation will not form on the walls of the window opening, and the windows will not fog.

How to install a sandwich panel on a plastic door

Increasingly, the owners of the houses opt for plastic doors, therefore, slopes for them should also choose the right type and type of material. Modern sandwich panels are perfect for this. You can install them yourself, using detailed instructions and owning the skills of repair or construction.

The process of installing sandwich panels for doors is as follows:

And as materials, accessories, the following construction products should be used:

  • Buy a sandwich panel of suitable thickness in advance;
  • Measuring and cutting tools (these include laser or alcohol level, roulette, acute construction knife or electrician, drill)
  • Accessories for finishing measures (spatula, trowel, PVC focuses, nippers for plastic, masking tape, screws) mounting foam, plaster, primer.

Armed with everything necessary, the installation measures begin directly.

Step.by.step installation

Available price, ease of material, ease of installation and ease of operation allowed to use a sandwich panel very widely in the decoration of window openings.
