Our sub-frames are made of ecological PVC. They are used on new buildings and in case of renovation.
The main quality of this innovative product is the great mechanical resistance and non-deformability of the materials that allows this system to guarantee a timeless duration, the elimination of all maintenance costs, but above all a net saving on heating and cooling costs of the house.
They represent the ideal completion for quality windows, which alone are not enough to guarantee maximum energy efficiency.
Here are some of the advantages of these sub-frames:
- NO WASTE: thanks to its thermal performance, it allows a net saving on the annual heating and cooling costs;
- NO COSTS: great mechanical resistance and non-deformability of the materials allow this subframe system to guarantee a timeless duration, eliminating any maintenance costs.
- NO MOLDS: certified laboratory studies attest to the possibility of totally avoiding the creation of mold and condensation around the windows (and therefore a healthy environment and a better living comfort).
Below we show how the old windows are replaced and how the sub-frame is installed without masonry:
