Replacement Windows & Doors

Take Advantage of Cardinal IG Sealed Glass Technology

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 25 years! Most windows have a standard failure rate of about 9% in 15 years. Modern spacer systems simply cannot match the long-term durability and energy benefits that this window technology offers.
