Certified Alaska Tough Windows

How is a Certified Alaska Tough window different from other windows?

MTL frosted windowWindows are typically the least insulated portion of a house. In very cold climates such as Alaska, poor windows can lead to indoor frost build-up, cold drafts, and a reduced window life expectancy. For this reason the Cold Climate Housing Research Center (CCHRC) has created a standard to help consumers identify windows which have been tested to meet standards that will hold up in the extreme climates of Alaska. CCHRC is located in Interior Alaska where heating systems are designed for -47 degrees Fahrenheit, and so has experience dealing with the many problems caused by low quality windows and knows the value of windows that will allow residents to enjoy spectacular views without feeling cold for many years.

Windows that have been Certified Alaska Tough have been tested to meet a more stringent insulation and air-tightness standard than Energy Star windows and have been certified to have superior air, water, and structural performance.
