When replacing windows , an additional question always arises about how to make slopes for plastic windows. There are many options at the moment, but not all of them are successful. Consider them, starting with the cheapest in terms of the material used.
Slopes for plastic windows can be done by plastering in several layers. After the advent of plastic windows, this was the most popular and familiar way.
The plaster layer is applied in several layers according to the technology. The finish layer is covered with paint. Actually, nothing new, and everything would be fine if it were not for a few "buts" discovered during operation. The main problems are the insufficient level of reliability of the connection of plaster and plastic and the low rate of thermal insulation of the plaster. This leads to the formation of cracks, violation of the thermal insulation of the slope and to the appearance of the effect of “crying” windows, in other words, to the formation of condensate. This method is currently losing its popularity. In addition, it is labor intensive, requiring a lot of time to complete.
To replace the first method came various options, implying gluing slopes. These include adhesive slopes for plastic windows (pasting with thin plastic), plasterboard finishing (the top layer is plastic). Both of these methods, having significant drawbacks, did not take root in the construction technology market. Drywall is not suitable for finishing slopes due to instability to dampness, and thin plastic often does not withstand the emerging stresses due to temperature changes. As a result, such slopes are short-lived and quickly lose their external attractiveness.
Expanded polystyrene is also used. The disadvantage of this method is its fragility and rapid loss of appearance due to color changes. In addition, this material easily misses when exposed.
Plastic slopes for windows made of double-sided sandwich panels have proven themselves well. They have sufficient moisture resistance and vapor impermeability. In addition, such slopes are durable and beautifully shape the window opening. Installation does not require much time.
Pay attention to the fact that sometimes they offer to perform slopes for plastic windows from one-sided sandwich panels. This option should be rejected. The cost of such panels is lower, but the quality of the output will be better. They do not possess proper rigidity and are subject to deformation.
Also, slopes for PVC windows can be made of sheet plastic, which is also quite viable and widely used at the present time. It is important to choose a high-quality finishing material and not to save on its thickness. It is optimal to choose 10 mm thick plastic.
If you do not plan to make slopes for plastic windows on your own, it is very important, as with any other work, to find qualified workers. It is most reliable to find a person or team on the recommendation of friends. If there is such an opportunity, start purchasing the material yourself.
