TriSeal, Edgetech I.G.'s flexible foam spacer, reduces energy consumption by up to 15% in curtain wall systems

January 20, 2009 |

Cambridge, Ohio – January 20, 2009 – When designing for sustainability and energy efficiency, it is important to consider the entire window system and its components. Warm edge spacer systems are known to improve energy efficiency in buildings, but Edgetech I.G. cautions architects that not all warm edge spacers are created the same, or provide the same level of benefits. Edgetech manufactures Super Spacer® TriSeal™, a desiccated silicone foam spacer technology designed specifically to enhance the performance of architectural and captured glazed insulating glass units.

“By definition a warm edge spacer is any system that performs better than traditional cold edge aluminum spacers,” said Joe Erb, product manager for Edgetech I.G. “Stainless steel is popular among commercial architects because it does provide an improvement in efficiency over aluminum. However, it is important to remember that stainless steel is still metal, and is therefore conductive. Super Spacer TriSeal is a non-metal alternative that provides improved energy efficiency, durability and comparable structural strength to stainless steel and other metal spacers.”

Edgetech’s TriSeal is specially engineered with a triple-seal design that includes desiccated silicone foam, acrylic adhesive and multi-layer vapor barrier for superior condensation resistance. The flexible foam construction also allows for the natural expansion and contraction of insulating glass caused by temperature changes, barometric pressure changes, wind loads and snow loads. Where a rigid metal might cause breaks in the seal from long-term stress, TriSeal is able to bounce back – providing a longer lasting seal and long-term energy saving benefits.


 “Because of TriSeal’s special no-metal design, seal failures are dramatically reduced or eliminated and noise is reduced up to two decibels over metal-based spacers,” Erb said. “In terms of efficiency, the unique triple-seal design can reduce energy consumption by up to 15 percent within curtain wall glazing systems,”

TriSeal is compatible with silicone structural sealant, as well as with other structural sealants.

All Super Spacer products are sustainable and contribute to achieving LEED® certification, even in the most demanding applications.
