Beachwood, Ohio-based TruSeal Technologies Inc.'s Insuledge, dual sealed with polysulfide, has passed the requirements outlined by European testing standards EN1279-2, 3 and 6 according to the final report by Dutch test institute TNO-TPD.

Insuledge is a warm-edge flexible spacer system for insulating glass (IG) units. The hollow, non-metal spacer incorporates a proprietary molding process, and its dual seal system allows Insuledge to be dual sealed with most common structural and thermoplastic IG secondary sealants.

"The warm-edge technology that we use in Insuledge gives manufacturers a greater advantage with meeting European energy conservation codes, such as Part L of U.K.'s Building Act," said August Coppola, president of TruSeal. "K-values are reduced, limiting the amount of heat that is transferred through the edge seal spacer system. We consider the EN1279 certification a great step in better serving our European customers."
