Windows That Last Longer

20 years of incredible durability and insulation

 

Cardinal IG Sealed Glass Technology produces some of the best-insulated windows on the market. This technology incorporates a stainless-steel spacer with airtight corners and the dual-seal construction of compressed PIB and silicone. The IG units are filled with Argon, designed to improve the window’s insulation capacity and eliminate the potential for any moisture accumulation within the window.

This technology guarantees a 0.2% seal failure rate over the course of 20 years! Most windows have a standard failure rate of about 9% in 15 years. Cardinal IG Sealed Glass Technology is so reliable that it boasts a 0.2% seal failure rate and a 20-year warranty. Modern spacer systems simply cannot match the long-term durability and energy benefits that this window technology offers.
