Duralite® Insulating Glass Spacer System
3rd generation warm-edge technology using no metals.


Duralite at a Glance

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.
