PVC and aluminum windows and doors are becoming more popular as compared to wooden carpentry. The biggest advantage of PVC and aluminum doors and windows is that it requires very little maintenance – it only needs occasional cleaning and wash. There is no need for painting. Rain, humidity and temperature changes cannot damage it. For this reason, aluminum and PVC windows and doors are a much better solution than wooden carpentry.

It is extremely flexible and different shapes and dimensions of windows and doors can be made, all in accordance with the individual needs of clients and architectural and construction solutions of the building.

Windows are one of the most important components of housing units in terms of low energy consumption. Energy savings are achieved by replacing old wooden windows with a single pane with new PVC or aluminum windows with double low-emission panes.

Low-emission panes, filled with argon, are a type of thermal protecting glass which will along with the ALU and PVC window frames reduce the loss of thermal energy in winter as well as the quantity of the thermal energy which will enter through the window into the building in summer.
