BENGglas is a perfect product for the renovation market. Unlike traditional insulating glass, vacuum glass is extremely thin (6.3 mm). As a result, BENGglas can be installed in existing frames and considerable savings are made on replacing frames.

This is also a major step towards making existing homes more sustainable. Traditional insulating glass (U=2.8) or single glazing (U=5.8) has a low insulation value. BENGglas , with a U value of 0.4, will significantly improve the insulation value of existing homes!
