QuadraTherm – The Ultimate Dual Pane Insulation System provides triple-glazed performance with dual-glazed cost & reliability. Using the patented 14-layer solar reflective coating keeps your home cooler in hot weather and warmer in cold weather. The patented multi-layer heat retention coating keeps your home’s interior heat from transmitting through the window out of your home when it’s cold outside.
INTERESTING FACT: Some might assume triple glazed windows are a better option than duel glazed. In truth, dual-glazed units have half as many seals as triple, resulting in half the possibility for failure.
