How much energy do ClearVue windows save?

Double glazed

Similarly to conventional double-glazed low-e windows, the heating and cooling energy costs savings are near 40%, compared to using single-pane windows.

Triple glazed

About double the amount of energy generated per year is saved through superior thermal insulation property of ClearVue window products.

Quadruple glazed

Even better thermal insulation and energy savings, compared to triple-glazed systems.

Vacuum glazed

Vacuum glazed windows reduce the thermal insulation U-factor to well below 1 W/(m2*K), the range not accessible with alternative technologies. Vacuum gaps are typically about 1mm wide, will not reduce power generation, and lead to the ultimate performance in thermal energy savings.
