When the elements come knocking, windows made with flexible foam Super Spacer^® will more than meet the challenge. The flexible foam technology of Super Spacer 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 don’t allow for the natural expansion and contraction that must occur in the insulating glass unit to offset the effects of these pressures on the glass. The results are stress cracks that eventually lead to seal failure. Windows made with flexible foam Super Spacer develop far fewer stress cracks than windows made with rigid spacers. Fewer stress cracks with Super Spacer means fewer call backs and replacements.

 

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 units last up to five times longer in durability tests than single seal units.

 

The results are obvious. Structural foam combines with acrylic adhesive strength to form Super Spacer, the most reliable insulating glass unit on the market.

 

We don’t just make these claims; we have the data to prove it. One week spent in a P-1 chamber – known as the industry’s toughest durability test – is considered by industry experts to be equivalent to approximately one year in the field.  Standard Super Spacer backed with hot-melt butyl passes at least 60 weeks in the P-1 chamber, all the way up to Premium Plus, which has surpassed 125 weeks of testing.
