ComfortPlus™ Clear can be used where passive solar design principles are used because it has a higher solar heat gain coefficient (SHGC) than ComfortPlus™ Neutral. Consequently, it has a higher solar heat gain, so it allows more energy through, making it suitable for north facing buildings during the winter months where it can gain from free heat (energy). ComfortPlus Clear has the same colour reflectance as ordinary clear glass where Neutral has a blueish grey appearance.
