Super Spacer® is made with Thermoset Spacer (TSS®) technology. This technology ensures that the spacer will expand and contract, but it will always maintain its structural integrity by returning to its original shape. 

This is very important because windows are constantly exposed to temperature changes, UV ray bombardment, barometric pressure changes and wind load. Other rigid spacers containing metal do not allow for the natural expansion and contraction that must occur in the insulated glass unit to offset the effects of these pressures on the glass. The results are stress cracks that eventually lead to seal failure.

Super Spacer is a dual-seal system that uses a high-performance acrylic adhesive for its structural seal. Backed with a moisture vapor seal, Super Spacer insulating glass lasts five times longer in durability tests than single seal units.
