Super Spacer

If only the strong survive, then we’ll outlast all the rest. All Super Spacer® products meet the challenge of the P-1 chamber, the test many engineers consider the world’s toughest. One week spent in a P-1 chamber is equivalent to one year in the field, and Super Spacer survives with long-term P1 performance with a low seal failure history within the industry.

Super Spacer expands and contracts and always returns to its original shape, protecting against stress cracks that can lead to seal failure. Super Spacer’s 100% memory formula stands up to a wide range of temperatures, and is designed to provide outstanding UV resistance.

Full-Metal Spacer
Metal spacer is rigid—Seal stress can result in seal failure


Less-Metal Spacer Mid-performance spacer systems that still contain metal improve condensation resistance.

NO-Metal Super Spacer
All-foam design dramatically reduces interior condensation, delivering a clear view in warm-edge technology.

A dual-seal, NO-Metal, warm-edge spacer system featuring Super Spacer® is better able to ensure National Fenestration Rating Council (NFRC) ENERGY STAR® certification by providing the best thermal conductivity, the lowest U-Factor among dual-seal systems and the best durability available in the industry.

The all-foam formula of Super Spacer® blocks the heat escape path and provides one of the best thermal performances in the industry.

Condensation can lead to more than bacteria and molds. It can increase the likelihood of fungi, viruses and mites that cause respiratory infections, allergies and asthma.

Improved sound absorption over traditional metal spacers; NO-Metal Super Spacer is a huge help in keeping the decibels down.

Our dual-seal system helps Super Spacer insulating glass units last up to nine times longer* in durability tests than single-seal units.

Our all-foam formula offsets the effects of temperature changes, barometric pressure, wind load and glazing pressure. The end result is less seal failure and fewer stress cracks.

Super Spacer units withstand the 140°F/60°C temperatures, 95–100% humidity and constant UV bombardment in the world’s toughest durability test—the P-1 chamber.
