However, the window sill itself is exposed to adverse effects every day: temperature changes, sun rays, mechanical loads. All these nuances predetermine the features of installation and installation of the product.

Preparatory work

Tools and materials

In order for the installation process to be more comfortable and not to drag out, it is necessary to prepare all the construction equipment in advance. The list below is easily adjusted to the specific situation and financial possibilities. Some tools can be replaced: for example, a hacksaw for metal will be an inexpensive replacement of jigsaw. It is not necessary to buy all the tools, because in the future they may simply not be needed, or they will be useful only once, so it is better to take the same jigsaw or puncher from relatives or friends.

So, in order to ensure that the process of installing the plastic window sill does not become burdensome and does not last for several days, it is necessary to stock up with the following consumables in advance:

• For the laying of plastic linen - wooden blocks.
• For cracking cracks - silicone or liquid plastic.
• For reliable fastening - self-tapping screws.
• For heat and sound insulation, seals - 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 not in a hurry. If you approach this procedure irresponsibly and carelessly, you can easily destroy the slopes behind the batteries.

For dismantling the old window sill, it is useful to mount, which must be inserted between the masonry and the boards and pushing slightly, slightly loosening the windowsill. It happens that the board does not immediately lend itself to mounting, in this case, to use the perforator to destroy the lower part of the slopes. And then again the mount comes into play. Often these actions are enough to get rid of the old window sill. Rarely, when it does not lend itself to and remains immobile, an electric jigsaw will be useful in this case. The electric jigsaw makes a nail, after which again the course is mounted.

Trimming and marking

Plastic sills can be ordered both ready-made and for installation, i.e. Cut the product out of the plastic cloth with your own hands. For this, competent marking with the help of centimeter tape and a construction pencil is done. Often, windowsills for plastic windows are available in standard sizes, the standard width of plastic windowsills is 60 cm, which allows them to be installed in almost any building.

The width of the window frame to the edge of the window opening is initially measured. Then the window sill is cut with a margin of two centimeters. The window sill is selected at its own discretion. Do not forget that a too large ledge can interfere with the normal spread of heat from the heaters and lead to condensation on the panes.

The maximum length of the plastic window sill is 3 meters, the width is within 25-70 cm. If the width of the plastic window sill is too large, the excess is simply cut off. The cutting line should pass behind the stiffeners located inside the product, by 0.5 - 1 cm. Then the product will fit well with the window frame.

PVC is more convenient to cut with an electric jigsaw, rather than a hacksaw. In the latter case, you should be more careful and careful not to damage the material itself. Observance of elementary safety rules will be very handy, therefore it is better to prepare gloves and safety glasses in advance.

Lining and fixing of the plastic window sill

• The concrete base on which the plastic window sill will be fastened is thoroughly cleaned of construction debris, then it must be primed. Primer is needed to protect against the formation of mold. Spackle cavities and irregularities are not necessary. Of course, if there are large cracks on the surface, plastering is necessary.
• For laying it is necessary to lay wooden bars of appropriate thickness, i.e.so that the window sill is kept flat horizontally, rather than leaning downward, as is often the case with improper installation. It is better when the thickness of the bars is the same as that of the window sill itself. Bars will take on all the load from the window sill.
• At the same stage, the puncher makes slopes. The plastic window sill must go into the formed groove and under the bottom edge of the window frame unhindered. Make sure that the structure is snug against the frame. Wedges are placed underneath.
• After adjusting the window sill, fix it with screws. This is done on the other side of the frame.
• The space under the window sill, niches in the slopes is blown with professional mounting foam. Before blowing on the windowsill, you should put the load so that the foam does not lift the product.
• Foam will dry completely after a couple of days, so at this time it's better not to use the window sill. Only after complete drying of excess foam is cut with a construction knife, and the remaining gaps and cracks are treated with a sealant.
• Having gone through all the steps of fastening the plastic window sill, you can proceed to the final finishing - fixing the end caps to the glue.
