TRI-SEAL
Reduces Sealant Stress: Super Spacer’s thermoset silicone polymer material expands and contracts and always returns to its original shape.
Promotes Sound Absorption: The closed-cell polymer of Super Spacer transmits very little sound compared to conventional aluminum or less-metal warm edge spacers. We recommend the use of Super Spacer wherever noise from airplanes, trains or automobiles may be a problem for building occupants.
Improves Condensation Resistance: The significantly reduced tendency of Insulated Glazing (IG) units fabricated with Super Spacer to exhibit interior condensation or frosting means that the health problems associated with mold may be virtually eliminated.
The No-Metal Advantage: The edge of an IG unit is the most vulnerable part of the glass to heating and cooling losses, condensation and frosting. Super Spacer contains NO-Metal and is one of the most thermally efficient IG spacers available in the market today.
Globally Tested and Proven Performance: Super Spacer is the world’s first polymer, NO-Metal warm edge spacer. Over 1 billion feet of Super Spacer has been used worldwide since the start of production in 1989. The company received the 1994 “Solar Company of the Year” award issued by Solar Energy Society of Canada, Inc. Super Spacer was awarded the DWM Green Product Award in both 2009 and 2010.
