The main rule than cutting a sandwich panel is the use of tools that produce only cold cutting, because overheating of metal surfaces can lead to a violation of the protective polymer coating and corrosion.

For cutting panels, it is recommended to use circular saws and manual electrolobsics. In addition, you can do the trim with scissors for metal, but only if a separate cutting of each metal surface. After each cutting of the panels, all the applied surfaces and locks should be completely cleaned of metal chips.

These plates are used in large construction to build frame structures. Therefore, structural-distinished panels are introduced. They are made using 2 directed sawfly tiles, between them, under the influence of pressure, a layer of dense insulation is glued or polyurethane foam is pumped.

In small construction, such blocks are used for structures based on an iron frame. Plates with metallic spraying are needed in the form of a fencing structure.

We will cut. Only than?

Cutting panels must be carried out strictly horizontally. The control of the horizontal line of the upcoming section is carried out on both sides of the panel by the construction level. First, the metal is cut, then the insulation layer.

When using a corner grinder, a high temperature occurs at the site of the section, which can lead to a heater. In addition, overheated metal loses its corrosion stability, therefore, only a disc or electric saw for metal or an electroplassic ribbon or an electric lobe is used for cutting sandwich panels. As an exception and only with minor volumes of work, electric wizards are allowed for metal.

With panels where wood is used as a shell or PVC is everything easier. they are cut by an electrician or ordinary hand saw.

How to cut and fix the sandwich panel. nuances and installation features

Installation of sandwich panels is a very important stage in the construction of the building, and just as responsible. Important nuances here are not so much in how to fix the sandwich panel, but in accordance with the implementation of their installation by the technological process. The service life of the building as a whole depends on this.

Avoid errors and misses

A large number of errors in the installation of sandwich panels are associated with an inattentive, cursory reading of the design and installation documentation, and it often contains comprehensive information about the panels and connecting elements.

But even the exact follow.up of the instruction cannot insure from some errors during installation, namely:

• Metal sandwich panels should be without damage and traces of corrosion. In the same condition, there should be a metal frame on which the fastening will be carried out,
• If the panels are attached to the wooden frame, it must be saturated with antiseptics and insecticides,
• Polluted sandwich panels cannot be cleaned with detergents containing alkalis, acids and abrasives,
• The protective film should not be under the influence of direct sunlight. It should also be protected from solvents,
• The protective film must be removed from the sandwich panels no later than a week and a half after installation, but this cannot be done in very hot and very cold weather,
• You can not walk on sandwich panels, put various objects on their surface and attach something to them.

How to raise and install panels correctly?

A transport package with sandwich panels (read about the technical characteristics of these products in this article) rises to the installation height with special equipment-vacuum lifts.

If a regular lifting valve is used for these purposes, it is necessary to take a number of measures to prevent damage to the panels:

• Soft slings are used to raise the transport package. In this case, the capture of the slings itself is not allowed. The castle parts of the panels are protected from possible damage by slings with bars-struts, with a length of at least 122 cm, evenly located above and under the bag,
• You can’t raise a sandwich panel directly from a sandwich panel.

Also, in the process of work, the following rules should be followed:

• The panels should be joked strictly at an angle of 180 degrees, t.e. vertically. Docking from a different angle can lead to locking locks,
• Installation should be carried out extremely carefully to avoid damage to the protective coating. Otherwise, the service life of the panels will be significantly reduced.

We will cut. Only than?

Cutting panels must be carried out strictly horizontally. The control of the horizontal line of the upcoming section is carried out on both sides of the panel by the construction level. First, the metal is cut, then the insulation layer.

When using a corner grinder, a high temperature occurs at the site of the section, which can lead to a heater. In addition, overheated metal loses its corrosion stability, therefore, only a disc or electric saw for metal or an electroplassic ribbon or an electric lobe is used for cutting sandwich panels. As an exception and only with minor volumes of work, electric wizards are allowed for metal.

With panels where wood is used as a shell or PVC is everything easier. they are cut by an electrician or ordinary hand saw.

Fasten, but in moderation

Fasteners for sandwich panels are selected taking into account the type of structure and its thickness. As a rule, self.cutting screws (self.tapping screws) are used for this.

Their length is the sum of the thickness of the panel, frame and compensation of the height of the rubber washer (5 mm). The latter is required for use with self.tapping screws. it does not allow the metal head to damage the panel when screwing and sealing the mounting location.

The panel of 6 m long is attached with six self.tapping screws, 4 m long and less. four, with a length of more than 6 m. eight. Self.tapping screws are attached with an electric screwdriver with a pre.corrected tightening force.

With proper tightening, the washer is not deformed and at the same time tightly pressed to the metal. Too tightly tightening the puck, insufficiently strong does not ensure the tightness of the mount. The slanting self.tapping screw is categorically unacceptable.

Vertical and horizontal mount

The fastening of sandwich panels to metal structures can be carried out in two directions: vertical and horizontal. Both installation methods have their advantages and disadvantages.

If the floor has a small height (from 3 to 6 m), vertical installation is used. In this case, the panels are attached only to the guide profiles of the floor and ceiling, and are tightly connected by each other. The integrated and strong design created at the same time is spent on the “cold bridges” and does not have thermal losses. During installation, significant funds are saved, since there is no need for lifting special equipment and construction forests.

However, they cannot do without them if the floor height is more than 6 meters. Perhaps instead of forests you will need a carriage to provide facade work at the height. All of them, in addition, are unthinkable without the use of an autocrane. Additional costs are also required to strengthen the metal frame of the building to prevent high panels.

The level of expenses at such a height of the walls can be reduced with horizontal installation of sandwich panels. They are laid out one on the other and are attached to the edges to the columns of the frame. In this case, continuous sheathing is also formed. However, for the use of horizontal installation, it is necessary that the distance between the columns of the building frame is no more than 6 meters.

When installing sandwich panels, either a horizontal or vertical method should be used. Their combination is unacceptable.

The nuances of the installation of sandwich panels

With the vertical installation method, the first is laid out from the corner panel resting against the joint. With horizontal. first, the first row is performed from the base, and only after it. the next. Regardless of how to mount a sandwich panel, the work ends with the installation of a prescription panel. If necessary, its dimensions are adjusted at the spot by cutting.

Sandwich panels should not directly contact with the support structure. To avoid this, perform the gasket of the seal. If the panels have a polyurethane foam insulation, mounting foam is used, if from mineral wool. the same material. Polymer tape and silicone sealant are also used.

Sandwich panels have the first class cladding class correspond to GOST 30247.0-94

The correct installation of sandwich panels is one of the decisive factors that determine the strength and durability of the building. Therefore, great importance should be given not only to the quality of the sandwich panels themselves, but also with concomitant materials-pre-precious elements and components. And, most importantly, the process should be performed by qualified specialists, because errors can lead to negative consequences and damage to the structure. Sandwich panels are used to build walls and roofs of a quick-made building. Each kind of work has its own characteristics. Buying sandwich panels should be studied by those. documentation, which indicates the mounting nodes, types of additional elements and methods of applying components.

• Assembly and installation of metal structures
• Preparation of the metal frame. the metal is cleaned of corrosion, and then an alkyd primer is applied to its surface
• Execution of the sealing layer with the help of a self-adhesive sealing tape
• Mounting walls starts from the base or from the corner, silicone sealant is applied inside the castle
• Roof mounting starts from overhang to the skate, the sandwich panel is connected overlapping.
• Installation of additional elements

All work should be completed on the construction of the building frame, primer and painting of metal structure. Apply to the columns in the places of attachment. Before starting work, it is necessary to clear the construction site for unloading the panels, which then should be placed on a specially prepared lining of wood, foam or polystyrene. Then-open the packaging film from a pack of sandwich panels. After removing the film, inspect the locks of the panels for the presence of excess insulation. If they are available, excess insulation should be removed with a scraper.

The following tools are used for cutting:

It is forbidden to use an angle grinding machine (angular grinder) and other tools and methods that suggest a strong temperature effect. Such a strong heating of the metal sheet of the cladding leads to the destruction of glue and impaired adhesion of the insulation with metal, and, therefore, to gradual corrosion and impaired strength.

The raising sandwich panels is carried out using mechanical or vacuum grips (vacuum suckers). Applying mechanical captive brubsin, the panel can be lifted horizontally. Main-Vira type captures raise the panel in an upright position. Large pluses of vacuum captures is the speed of fastening of a sandwich panel, they allow fastening in less than ten minutes. They are more expensive than mechanical, but working with them is much more convenient. Using vacuum suction cups, the film should be removed in the places of fastening. There is no need to completely shoot the entire film, you can do this after the end of the mount. The fixed panel is raised using a crane or winch.

List of necessary equipment and building materials:

• Electric screwdriver
• Soft slings
• Mechanical or vacuum captures
• Scissors for metal
• Sealant
• Highlighting tape
• Self-cutting screws for sandwich panels
• Self.cutting screws for preliminary elements
• Level
• Hacksaw
• Continuous elements

Installation of wall sandwich panels

Installation of wall panels are done in the following ways: vertical and horizontal. When choosing a horizontal method, installation should begin from the foundation, when choosing a vertical. from the angle of the building. If necessary, a layer of insulating material and sealant are used between the foundation and the panel. For thermal insulation and adhesion of sandwich panels, a polyurethane sealing tape must be installed on the columns of the frame.

The horizontal method provides a strong connection of the locks under the weight of the panels. With this installation, the sandwich panels are attached with self-tapping screws along the length along the walls of the structure. When installing the panel, you should tightly press it to the frame, without damaging the polymer coating, then check in level.

Vertical installation is best suited for buildings with a wall height up to 6 meters. In this case, wall sandwich panels are attached in the area of ​​the base and roof. The peculiarity of such work in the use of special clamping devices to ensure the docking of adjacent panels, in the case of using panels of large length and, accordingly, mass. It is strictly forbidden to adjust the joints with shock impact.

Installation of wall panels: vertical and horizontal. When choosing a horizontal method, installing panels should begin from the foundation, when choosing a vertical. from the angle of the building.

The connection of the locks of wall sandwich panels should be very dense. With adverse temperature fluctuations, it is recommended to lay a sealant inside the lock to exclude violation of thermal insulation. In the conditions of the harsh northern climate, the sealant is laid from the internal and outer part of the lock.

The transverse joint of the panels is compacted using insulating material. For sandwich panels with mines.Mineral wool is used cotton wool, mineral wool or mounting foam is used for sandwich panels with PSB-S. The technological seam should be at least 20 mm and at the end of the installation is closed by additional elements.

How to make a thermal cutter

With your own hands, you will need it for the manufacture of a thermal cutter:

Automobile charger with manual current control mode.

In comparison with the factory, the thermal is not very convenient. Slots along the lining edges can be done with a corner grinder or a chain saw.

The first question that arises from the master-collar is how to do as correctly as possible, t.e. from all sides, cut the panels, and not only rectangular. Of course, in theory, everything looks just. But, unfortunately, often in this case, the joints do not converge independently of the SIP panels. In this matter, it is better to adhere to the Russian proverb: “Seven times measure. cut one”.

If you dream of becoming a happy homeowner and considering the technology of a builder of houses from SIP panels, then you are on the right track! We and our customers are already living in country houses.

The fact is that roofing sandwich panels are called roofing just because they simply do not need any more insulation or coating in any more. This is the same as the walls from the sandwich, which no one also insulates additionally.

You need to pay more attention to assembly. The builders have shut up my builders and, when installing the roof, they did not close a sandwich panel among themselves. Now in the cracks, condensate is periodically formed and moisture flows at the junction of the panels. Who knows how to solve such a problem with condensate?

In general, roofing sandwich panels are of the highest resistance to any atmospheric phenomena from the influence of sunlight to the influence of atmospheric precipitation. If after installing such a roof flows, then it is asked who collected it? Professionals and even ordinary people collect them very reliably, since in these panels the entire structure is imprisoned for a hard coupling panels with each other.

The main leaks are from incorrect body movements when screwing the self-cutting screws. If the normal slope and overflows are normal along the slope, then the program of the run does not affect the tightness. Problem places. communications passages, add.on. designs like a ladder, stretching, fences, etc.D.

The permissible span recommended by the manufacturer is the main document for which the bearing capacity of the panel itself is guaranteed. Calculating this ability cannot be established, t.to. You unknown specific data on the characteristics of the components and technology for manufacturing panels. precisely, you can only with your own trials. In the schedules and tables of the manufacturer, the span depends on the load (naturally), and on the scheme (cut/insoluble, sometimes the number of spans) laying the panel. And not somewhere 2 m. It can be 1.0 m. In this case, there are requirements for the width of the support. In snow bags, sometimes no panels pass with any step of the runs. it simply does not withstand the insulation for crusting.

P.S. All of the above refers to the right good sandwich.

He designed the first roof from sandwich panels back in 2001. Literally immediately began leaks due to improper execution of the junction node. The junction of the panels should have rolled up in length, well, of course, no one could really do this, t.to. There were no specialists. Well, now, in principle, they began to make panels with a corrugated upper profile and do not need to pile up anything.

If the roof from sandwich panels flows:

one.When installing sandwich panels, a sealing gum is placed, although the sandwich is hooked by the lock.

2.When fastening the panels to the design with self.tapping plates, you need a little silicone (from practice).

The adjoining must be sealed with silicone, not foam, it is destroyed over time.

I would be glad if something from this helped you.

Faced with similar problems, rolled the entire PVC roof with a membrane and no leaks.

Choosing a sandwich panel as a roofing, you get an excellent opportunity not only to reduce construction time, but also to save on construction significantly. As practice has shown, the roof of rapidly vested profiled products compared to traditional coatings costs developers 20-30% cheaper. The main thing is that the design is correctly designed and mounted. Then she will retain all her advantages for many years and will delight with her reliability and extraordinary beauty.

How to cut an opening in a sandwich panel. The start of the installation of sandwich panels.

When everything is ready and staffed, they will determine the sequence of installation. Depending on the size of the building, the panel can be mounted in a horizontal or vertical position.

Before installing the panel on the columns and crossbars, in places of contact, special self.adhesive tapes are glued. Ribbons reduce vibration and serve as a tight fit of the panels to the structures of the building.

The panels are fixed with special.cut screws of carbon or stainless steel with a sealant, with a broom for metal, if they are attached to metal structures.

If the frame of the building is made of wood, then the panel is pre.drilled and laid down with wood screws. The concrete is fixed with special dowels of preliminary behind the drilling panel and concrete structures. The length of the screws of the screws is chosen based on the thickness of the panels.

If the panel is 50 mm thick, then a 75mm or 200mm panel is used 240 mm screw.

Installation of sandwich panels begins with the corners of the building. Mount the panels using special exciting strips. The clamp is a special screw capture with rubberized lips, with hinges for lifting a crane.

Also, traverses with vacuum capture are used to raise the panels. If the panel is not large and not heavy allowed to lift and fix it manually. Mount the panels taking into account all technological holes specified in the project.

Holes for windows, doors, engineering networks are marked and cut out on the ground. In this case, the proverb “Measure seven times and cut it off once, by the way, the panels cost from 1,500 per 1 m2 and, if not correctly cut off, then in most cases you can’t put it anywhere.

Design the holes on the sandwich on both sides and cut off an electric jigsaw with saws for metal. Cutting off corner grinders, with a cutting circle for metal, the edges on the panel are torn. Screwdrivers are also used to fasten the panels with screws to the construction of the building. From the technique use a crane and a telescopic tower, which work in a pair.

How to cut and fix the sandwich panel. nuances and installation features

Installation of sandwich panels is a very important stage in the construction of the building, and just as responsible. Important nuances here are not so much in how to fix the sandwich panel, but in accordance with the implementation of their installation by the technological process. The service life of the building as a whole depends on this.

Avoid errors and misses

A large number of errors in the installation of sandwich panels are associated with an inattentive, cursory reading of the design and installation documentation, and it often contains comprehensive information about the panels and connecting elements.

But even the exact follow.up of the instruction cannot insure from some errors during installation, namely:

• Metal sandwich panels should be without damage and traces of corrosion. In the same condition, there should be a metal frame on which the fastening will be carried out,
• If the panels are attached to the wooden frame, it must be saturated with antiseptics and insecticides,
• Polluted sandwich panels cannot be cleaned with detergents containing alkalis, acids and abrasives,
• The protective film should not be under the influence of direct sunlight. It should also be protected from solvents,
• The protective film must be removed from the sandwich panels no later than a week and a half after installation, but this cannot be done in very hot and very cold weather,
• You can not walk on sandwich panels, put various objects on their surface and attach something to them.

How to raise and install panels correctly?

A transport package with sandwich panels (read about the technical characteristics of these products in this article) rises to the installation height with special equipment-vacuum lifts.

If a regular lifting valve is used for these purposes, it is necessary to take a number of measures to prevent damage to the panels:

• Soft slings are used to raise the transport package. In this case, the capture of the slings itself is not allowed. The castle parts of the panels are protected from possible damage by slings with bars-struts, with a length of at least 122 cm, evenly located above and under the bag,
• You can’t raise a sandwich panel directly from a sandwich panel.

Also, in the process of work, the following rules should be followed:

• The panels should be joked strictly at an angle of 180 degrees, t.e. vertically. Docking from a different angle can lead to locking locks,
• Installation should be carried out extremely carefully to avoid damage to the protective coating. Otherwise, the service life of the panels will be significantly reduced.

We will cut. Only than?

Cutting panels must be carried out strictly horizontally. The control of the horizontal line of the upcoming section is carried out on both sides of the panel by the construction level. First, the metal is cut, then the insulation layer.

When using a corner grinder, a high temperature occurs at the site of the section, which can lead to a heater. In addition, overheated metal loses its corrosion stability, therefore, only a disc or electric saw for metal or an electroplassic ribbon or an electric lobe is used for cutting sandwich panels. As an exception and only with minor volumes of work, electric wizards are allowed for metal.

With panels where wood is used as a shell or PVC is everything easier. they are cut by an electrician or ordinary hand saw.

Fasten, but in moderation

Fasteners for sandwich panels are selected taking into account the type of structure and its thickness. As a rule, self.cutting screws (self.tapping screws) are used for this.

Their length is the sum of the thickness of the panel, frame and compensation of the height of the rubber washer (5 mm). The latter is required for use with self.tapping screws. it does not allow the metal head to damage the panel when screwing and sealing the mounting location.

The panel of 6 m long is attached with six self.tapping screws, 4 m long and less. four, with a length of more than 6 m. eight. Self.tapping screws are attached with an electric screwdriver with a pre.corrected tightening force.

With proper tightening, the washer is not deformed and at the same time tightly pressed to the metal. Too tightly tightening the puck, insufficiently strong does not ensure the tightness of the mount. The slanting self.tapping screw is categorically unacceptable.

Vertical and horizontal mount

The fastening of sandwich panels to metal structures can be carried out in two directions: vertical and horizontal. Both installation methods have their advantages and disadvantages.

If the floor has a small height (from 3 to 6 m), vertical installation is used. In this case, the panels are attached only to the guide profiles of the floor and ceiling, and are tightly connected by each other. The integrated and strong design created at the same time is spent on the “cold bridges” and does not have thermal losses. During installation, significant funds are saved, since there is no need for lifting special equipment and construction forests.

However, they cannot do without them if the floor height is more than 6 meters. Perhaps instead of forests you will need a carriage to provide facade work at the height. All of them, in addition, are unthinkable without the use of an autocrane. Additional costs are also required to strengthen the metal frame of the building to prevent high panels.

The level of expenses at such a height of the walls can be reduced with horizontal installation of sandwich panels. They are laid out one on the other and are attached to the edges to the columns of the frame. In this case, continuous sheathing is also formed. However, for the use of horizontal installation, it is necessary that the distance between the columns of the building frame is no more than 6 meters.

When installing sandwich panels, either a horizontal or vertical method should be used. Their combination is unacceptable.

The nuances of the installation of sandwich panels

With the vertical installation method, the first is laid out from the corner panel resting against the joint. With horizontal. first, the first row is performed from the base, and only after it. the next. Regardless of how to mount a sandwich panel, the work ends with the installation of a prescription panel. If necessary, its dimensions are adjusted at the spot by cutting.

Sandwich panels should not directly contact with the support structure. To avoid this, perform the gasket of the seal. If the panels have a polyurethane foam insulation, mounting foam is used, if from mineral wool. the same material. Polymer tape and silicone sealant are also used.

Installation of sandwich panels

The installation of this material is carried out in any weather, it is only necessary to take into account the established temperature indicators for the use of sealant.

The qualitatively operating characteristics of products with mineral wool can worsen if you work with them during the rain.

If you need to wash off the dirt, you should use the usual soap solution and running water.

Panels should be protected from shock, mechanical damage. If the surface damage occurs, then they are disguised as special repair paint.

When pauses during installation, each panel is fixed with screws to the supporting structure.

Installation instructions for sandwich panels

All connecting elements should be located at an angle of 90 °. Any inconsistency of this rule is considered marriage.

Optimal schemes of screws:

Preliminary work, preparation for installation.

As a rule, the installation process itself precedes the receipt of official design and installation documentation containing a certain set of schemes, drawings, statements, manuals, and so on. The preparation of documentation is engaged in profile organizations. Immediately before the installation, it is necessary to verify all the sizes indicated in the projects and check the straightforwardness of the supporting structures in order to avoid negative consequences in the future.

The material should be lifted using lifters, using the method of mechanical capture or vacuum suction cups. In order to prevent the fall of the material, it is fixed with insurance belts, and their discharge is carried out only after installing the panel in the desired position. Vacuum suction cups. the most effective lifting method.

Installation cutting is carried out by electrician, electric wizards, circular saw. After each drilling, the surface should be thoroughly cleaned of chips. The necessary marking is carried out with soft building pencils, but not with sharp objects!

The fastening of sandwich panels to the supporting structure, usually made of wood, steel or concrete, is carried out by special self-tapping screws made. They are located strictly at an angle of 90º. An electric drill and electric screwdriver are relevant as a working tool. To achieve extremely reliable fastening, sealing washers, dowels are used.

When calculating, the following parameters are taken into account:

Before starting installation work, it is first necessary to determine the maximum allowable distance between the supports.

The installation process of wall sandwich panels.

The wall.type panels are mounted either vertically or horizontally. The horizontal installation begins with the lower tiers, and the vertical installation. from the corner, from the panel that will then fall into the joint. With horizontal laying, lay the panels with a groove down, so that in the future the water can drain freely. By laying each third panel, it is necessary to ensure that the position of the structure corresponds to the project, as well as protect the panels from mechanical damage.

With vertical installation, it is necessary to ensure a tight fit of individual elements to each other. To improve the quality of the seal in the grooves, silicone sealant should be laid. It is introduced from the inside of the material. If the arrangement is performed in the freezer, silicone processing is necessary from the inside and outside the lock connection. To quickly apply the composition, use a special plunger gun.

It is required to carefully enter the sealant into each connection, avoiding gaps and spaces. When using the composition, the temperature regime indicated by the manufacturer should be observed.

Mineral wool is used to seal the seam. Work is carried out when laying sandwich panels on neighboring sections. The seal is required if products are made on the basis of mineral wool or polystyrene foam. When using polystyrene foam sheets, sealing with ordinary mounting foam is allowed. Experts must monitor the density of the material placement.

Malfly elements are installed upon completion of panels laying. Their fixation is carried out by screws or rivets. On top of the installation location is decorated using special planks.

Before starting installation, it is necessary to prepare a surface under a slope of 5%. If the length of the slope is more than 12 meters, it is required to form a overlap in accordance with the technological requirements and lay the panels from the overhang to the skate.

Materials are lifted using lifting equipment. When laying roofing sandwich panels, you need to carefully monitor the slope of the slope in order to prevent possible undesirable consequences. With an overlap of elements, it is necessary to seal the junction with the help of a sealant.

General rules for installing and caring for panels.

You can lay the material at any time of the year under various weather conditions. When using sealants, it is necessary to familiarize yourself with the recommendations of the manufacturer regarding the temperature regime for their application.

During breaks in the work, it is necessary to fix the material to the supporting structures. Shots should be avoided in the process of installation and with further operation. It is required to periodically clean the surface of the panels with a soft brush and soap solution. It is not allowed to fix any equipment to the panels, it is better to attach it to the supporting structures.

The transverse and longitudinal joint of roofing sandwich panels.

To properly join the transverse panels, you need to remove the insulation and cut off the part of the steel lining of the upper panel. The cut is made from below, it is equal to the size of the overlap. On the upper part it is required to apply rubber or silicone sealant. Then the material is fixed to the frame. Metal sheathing of the upper panel is fixed using self.tapping screws.

After sealing transverse joints, it is necessary to process longitudinal castle sections. Silicon.based sealant is introduced into the junction groove immediately before laying roofing panels.

Now let’s talk about how and how to cut sandwich panels

Cutting the skin of sandwich panels from OSB-3 is quite easy, and you can saw it with anything: from circular saw and electrolobesis-to hand hacksaw. We do not recommend only using a chain saw, since the drink will turn out to be rough and with large errors.But in “field” conditions without using stationary equipment, cut a sandwich panel with a thickness of 174-224mm into one technique-a problem.

So, we act as follows: we saw the casing in turn from one side and the other, and then we cross the panel at the site of the cut. It is even better not to break the polystyrene foam, but to stretch through the cut, with sawing movements, the steel wire-then the cut of the SIP panels in the site of the saw is almost perfect.

The second question is how to make a mounting groove in a SIP panel

In the manufacture of a set of a house in the factory, to sample a groove for a key, as a rule, special machines are used. One of the examples of such equipment is presented on the website http: // kpt-SIP.ru/oborudovanie/Stanok-Vyborki/.

To select a groove in construction conditions, for example, when building a house from a SIP panel with your own hands, it is convenient to use a thermal, which is an electric heating element of a special shape (photo on the left).

If for some reason it is not possible to acquire factory manufacturing thermal, then it is easy to make a thermal cutter for sample the groove yourself (the photo on the right shows how it works).

For the manufacture of the simplest thermal cutter, a small piece of nichrome wire with a diameter of the order of 0 is required.8mm and a car charger with the possibility of manual current control.

Of course, it is not as convenient to work with such a thermal cutter as a factory thermal, since before the sample of polystyrene foam you have to make slots along it along the edges of the sheathing, for example, a corner grinder, or a chain saw. But when you have to cut a sandwich panel in the “field” conditions, it will come down.
