It has been designed to eliminate thermal bridges on windows and offers the best thermal characteristics on the market.

This system offers a set of technical and functional characteristics that give great quality to the installation process: innovative installation system, application of a special net to prevent cracks, hidden hollow for the seal, a frame for the application of the outside strip and a surface that can contain a self-expanding seal.

The interior part of the counterframe, made of DF or wood, is produced according to the dimensions of the window with or without the mosquito net and offers the space for the application of the inside strip against steam.

Designed to be very versatile and easy to work, the thermal counterframe can be tailor-made or supplied in the form of bars in order to optimize its use and avoid waste. Some joints applied on the windows give the possibility of using the entire frame. 90-degree brackets applied on the corners ensure great strength and robustness of the frame.

Together with DF & SVS installation system by Soudal, C1 SUPER solution has been tested to determine its waterproof characteristics according to the regulations UNI EN 1027/00 and UNI EN 12208/01 achieving results that can satisfy any type of need.

Fabbro can also provide high-density foam material to insulate the windowsill, or alternatively the complete insulation of the 4th side (see the description of the 4th side).
