Cascadia does not manufacture glazing units: our supplier is Cardinal Glass, recognized as the premier supplier of IGU’s in North America.

Our standard glazing unit is Cardinal LoĒ²-270® All Climate Solar Control, which blocks 83% of UV rays and 96% of the sun’s infrared heat - reducing solar heat gain by over 50% - while maintaining 70% light transmission. Upgrades to even more efficient IGUs are available (please see Energy Performance for options).
