North Tech passive windows, is with advanced European passive house system. It is extremely energy-efficient windows. The window frames is being well insulated and fitted with low-e glazing filled with argon or krypton to prevent heat transfer. We use thermally broken aluminium, triple or 4 panel low e insulating glass, wider weather strips. Basically, passive windows is with U value lower than 0.1 imperial. Hardware, we use imported German HOPPE+SIEGENIA hardware. This windows enhance living comfort and help reduce heating costs substantially. North Tech’s windows and doors pass North American NFRC, NAFS, CSA certifications, getting renewal every year. We are confident to provide you high quality window and doors with savings.
