PVC windows

The Monoblock system, also known as “French windows,” was developed for the construction of windows installed in the insulation layer. The wealth of available widths of Monoblock frames allows them to fit different thicknesses of thermal insulation. The unique shelf (sill) located on the outside of the frame not only aesthetically covers the insulation around the entire window, but also effectively eliminates potential thermal bridges.
The internal rebate of the Monoblock frame guarantees a nice installation from the inside of the room, which eliminates the need for additional gypsum flashing. Thanks to this system, French windows not only perform the function of insulation, but also look aesthetically pleasing both from the outside and inside
