Independent Testing Proves Intercept ULTRA Matches Thermal Efficiency of Foam Spacers

In recent independent testing conducted by Architectural Testing, Inc. (ATI), a vinyl window using the improved Intercept spacer made with stainless alloy (branded Intercept ULTRA) was proven to match the thermal efficiency of a window made with a foam spacer, according to a press release by GED Integrated solutions, manufacturer of fully integrated insulating glass and vinyl window and door fabrication systems.

ATI performed both simulation modeling and physical testing in accordance with AAMA 1503-98. Both windows registered a U-factor of 0.27 and a Condensation Resistance Factor (CRF) of 76.

"Intercept ULTRA's true value comes from the proven performance benefits that have led to the lowest callbacks in the industry, durability and longevity, the best gas retention, strongest corners available and quality aesthetics," said Ron Auletta, chief executive officer and president of GED Integrated Solutions. "Knowing these benefits come with thermal efficiency proven equal to anything else on the market gives manufacturers a clear choice for the premium spacer system."

Auletta also notes that manufacturers are realizing between $5 and $7 in labor and material savings per window with Intercept ULTRA.

Intercept ULTRA is made with a third-generation stainless alloy on an improved machinery and software system designed to work with the GED Intercept spacer manufacturing process. More than 10 billion feet of Intercept spacer is currently in use with fewer call-backs than any other system.

Intercept ULTRA's performance advantages include:

  • Patented U-shaped construction that flexes with temperature change to increase seal life and durability

  • Best gas retention due to the industry's longest moisture vapor transmission (MVT) path

  • The straightest grids, locked securely in place to match from one window to the next and never shift

  • Patented web corner system and four layers of protection to provide the strongest seal at the corner.

The Intercept ULTRA .0077 gauged stainless alloy is available in a full range of strip widths to make spacer sizes from 7/32 to 7/8 wide. It is exclusively distributed by Berlin Metals, LLC.
