Duralite™

3rd generation warm-edge technology using NO METAL

Patent No. 6,581,341

Duralite offers a new level of thermal performance to windows reducing conductivity by up to 45%. This radical improvement in thermal properties is achieved by eliminating metal and replacing over 60% of the spacer profile with air. The patented design featuring a unique composite laminating technology without the use of metal results in superior thermal and durability performance.

Test results performed by a third party have proven that Duralite offers the lowest U-value rating and best condensation resistance when compared to other spacers.

Duralite is thermally the best energy-efficient insulating glass system available on the market.
