As for protection, the window sills will prevent the formation of condensate on glass and moisture from open windows. However, the windowsill itself is subjected to adverse effects every day: temperature changes, sunlight, mechanical loads. All these nuances determine the features of the installation and installation of the product.
The materials from which the window sills are made are amazing: natural stone, marble conglomerate, laminated chipboard, artificial stone, etc. However, the most common materials are still PVC and wood. To install both a plastic and wooden windowsill, you can use a number of useful recommendations that will allow you to navigate at all stages of work.

- quickly and simply installed;
- does not need careful care;

- there can be any form.
As for the shortcomings, in fact there are not many of them. Naturally, the wrong installation will probably entail a problem, for example, the windowsill will stagger or its slope will be too large. The problem may arise with cutting edges. However, these are not the disadvantages of the material, but the incompetence of the master. The only negative property is inconsistency to mechanical influences, that is, the plastic surface is easy to scratch and damage it with a hot object. In general, the installation of plastic window sills with your own hands is always practical, pretty and affordable in price.
Preparatory work
Tools and materials

In order for the installation process to be more comfortable and not delayed, it is necessary to prepare all construction equipment in advance. The list presented below is easily adjusted to a specific situation and financial capabilities. Some tools can be replaced: for example, a metal habits will be an inexpensive replacement for an electrician. It is not necessary to buy all the tools, because in the future they may simply not be needed, or they will come in handy only once, so it is better to take the same jigsaw or punch from relatives or friends.
So, so that the process of installing a plastic windowsill does not become burdensome and drag out for several days, you need to stock up in advance with the following consumables:
- For laying a plastic fabric - wooden bars.
- For covering cracks - silicone or liquid plastic.
- For reliable fastening - screws.
- For heat and sound insulation, sealing- mounting foam.
In addition to the above, you can not do without special scissors for metal, hammer, mount, construction pencil, centimeter tape, screwdriver and perforator.
Dismantling the old windowsill
At this stage, you should be very careful and in no case in a hurry. If you approach this procedure irresponsibly and carelessly, then you can easily destroy the slopes behind the batteries.
To dismantle the old windowsill, a mount will be useful, which needs to be inserted between masonry and boards and slowly pressed, slightly loosening the windowsill. It happens that the board does not immediately lend itself to the mount, in this case, to destroy the lower part of the slopes, use a perforator. And then the mount comes into business again. Often these actions are enough to get rid of the old windowsill. Rarely, when it does not lend itself and remains motionless, an electric jigsaw will be useful in this case. The electrolobian is made, after which the mount is again used.

Cutting and marking
Plastic window sills can be ordered both ready -made and for installation, i.e. Cut the product from a plastic fabric with your own hands. To do this, competent markings are made using a centimeter tape and a construction pencil. Often, window sills for plastic windows are produced with a standard size, the standard width of plastic window sills is 60 cm, which allows you to install them in almost any building.
Initially, the width of the window frame is measured to the edge of the window opening. Then the windowsill with a margin of two centimeters is cut. The release of the windowsill is selected at its discretion. Do not forget that too much ledge can interfere with the normal spread of heat from heating devices and lead to the formation of condensate on glass.
The maximum length of the plastic window sill is 3 meters, the width is acceptable within 25-70 cm. If the width of the plastic windowsill is too large, the excess is simply cut. The cut line should pass behind the ribs of the stiffness located inside the product by 0.5 - 1 cm. Then the product will fit well with the window frame.
It is more convenient to cut PVC with an electrician than a hacksaw. In the latter case, you should be more careful and careful so as not to damage the material itself. Compliance with elementary safety rules will be very useful, therefore it is better to prepare gloves and protective glasses in advance.
Lining and mounting plastic windowsill
- The concrete base on which the plastic window sill will be attached is thoroughly cleaned of construction debris, then it is necessarily primed. A primer is needed to protect against mold. It is not necessary to putty the hollows and irregularities. Of course, if there are large cracks on the surface, then putty is necessary.
- For lining, it is necessary to lay wooden bars of the corresponding thickness, i.e. In order for the windowsill to hold exactly horizontally, and not lean down, as is often the case with improper installation. It is better when the thickness of the bars is the same as that of the windowsill itself. The bars will take on the entire load from the windowsill.
- At the same stage, slopes are made using a perforator. The plastic windowsill should freely enter the formed deepening and under the lower edge of the window frame. It is necessary to make sure that the design is tightly adjacent to the frame. Below is the wedges.
- Having adjusted the window sill, you should fix it with self -tapping screws. This is done on the other side of the frame plank.
- The space under the windowsill, niches in the slopes are blown by professional mounting foam. Before blowing on the window sill, put the load so that the foam does not lift the product.
- The foam will completely dry only after a couple of days, so it is better not to use the windowsill at this time. Only after the excess is completely dried, the foams are cut off with a construction knife, and the remaining gaps and cracks are treated with sealant.
- Having passed all the stages of fastening of the plastic windowsill, you can proceed to the final finish - fixing the end plugs on the glue.
