BENGglas® Double Coated (U=0,40)

BENGglas Double Coated keeps heat inside with its unique insulation value of U=0.40. At the same time, a smart sun-blocking coating prevents solar heat from entering. This ensures a consistently cool and comfortable home — and low energy bills, even on the hottest or coldest days.
