How To Cut A Pvc Window Sill

You can cut with different files. Let’s see how each of them works.

Saw with coarse teeth and set (when the teeth look slightly in different directions). When cutting, the jigsaw twitches, chips will be visible on the plastic. With due experience, the quality of work can be acceptable, but still such a file is not well suited for plastic.

Medium toothed and unset. The cut is smooth, the jigsaw twitches less. Chipping little.

Metal saw with fine teeth and small set. It takes a long time to cut. The cut is shaggy, with small notches. They can be corrected, but it will take time.

The conclusion is this: take a blade with medium teeth and without setting. This is the best option.

How to start installing a window sill

I will describe the process of installing a plastic window sill using the example of a window with a bal-window door. It is necessary install two window sills at once. One under the window, the other under the balconette door.

The old PVC window sill was dismantled. But first, it was necessary to dismantle the left slope of the window, since it was attached to the surface of the window sill. I will write about how to make slopes on windows later.

The surface for installation must be thoroughly cleaned of old foam, construction debris and dust, and then primed. Next, we proceed to the markup. It is necessary to cut both PVC window sills to the size we need. Everyone is free to decide how many centimeters the window sill will protrude relative to the wall, I think that this is not important. The main thing is that it does not block the heating radiator. In normal cases, I leave about five centimeters.

Since, in the example I describe, the right side of the window sill does not go under the slope of the window, but remains open, it will not be superfluous to check with her that there is a right angle. This is easy to do with a square. If there is no right angle, then you need to create one. Draw the line with a pencil and cut off.

Because, in the example I describe, the right side of the window sill does not go under the slope of the window, but remains open, then it will be completely superfluous to check with her that there is a right angle. It’s easy to do this using a square. If there is no right angle, then you need to make it. Draw the line with a pencil and cut off.

Above were listed the tools with which there is an option to cut off the plastic of the window sill. Don’t worry if the cut isn’t quite accurate. After all, usually, the edges are hidden behind the slopes, if not, then they are locked with plugs that I have not photographed (not criminal forgetfulness). I prefer to cut my angle grinder, only going down to medium rpm. I cut with an ordinary disc for metal.

In the process of installing the windowsill, one dharma should be learned. Its essence lies in the fact that the sill should be 5-7 mm. Go under the lower window frame. This is necessary to maintain the galactic order. We take into account when marking and cut off with a supply.

Probably you have heard or read that the window sill is installed on foam and pressed down from above, preventing it from being squeezed out by the expanding foam. It is right. The load does not allow the plane of the window sill to deviate upward. However, how to keep the sill from sinking down? What beacons to focus on for installation?

To install the stops, we need 8×40 and 8×60 dowel nails, which I have already mentioned. As you guessed, the window sill will rest against its own one of the planes specifically on the hats of these carnations.

Using a puncher, we drill holes with a diameter of 8 mm. And a depth of 40 mm. Insert dowels 40 mm long into the holes. But we take nails 60 mm long. This protruding length will allow us to adjust the caps to a suitable height and prevent the nails from falling through.

Plastic is cut quite easily with standard sawing tools and equipment:

  • Angle grinder;
  • Circular;
  • Electric jigsaw;
  • Hacksaw for wood or metal.

It is most advisable to use a jigsaw for cutting PVC windowsill. The angle grinder also copes well with this task. A circular saw is less preferable. Due to the high speed and large teeth of the saw blade, there is a high probability of destruction of the plastic product.

The reality around us is so abundant in plastic that one could set out to write management about the installation of a plastic window sill, using only plastic tools. But why make life difficult for yourself? We will use the tools that are available, regardless of the material from which they are made. What did we do with this earlier?

  • Hacksaw, jigsaw or angle grinder
  • Rack or laser level (both are better)
  • Polyurethane foam
  • Dowel nails 8×40 and 8×60
  • Square, tape measure, pencil
  • Puncher
  • Human hands

I will outline the process of installing a plastic window sill using the example of a window with a bal-box door. Need to install two window sills at once. One under the window, the other under the balconette door.

The old PVC window sill was dismantled. But why, I had to dismantle the left slope of the window, since it was attached to the surface of the window sill. What, in fact, how to make the slopes on the windows, I will write later.

The surface for installation must be painstakingly cleaned of old foam, construction debris and dust, and then primed. Then we proceed to the markup. It is necessary to cut both PVC window sills into a suitable size for us. Who is free to decide the extent to which the window sill will protrude relative to the wall, I think that this is not principled. The main thing is that it does not block the heating radiator. In ordinary cases, I leave approximately 5 cm.
