Edgetech’s dual-seal Super Spacer® Cushion Edge™ spacer system provides consistent bond and added efficiencies.As worldwide energy efficiency standards are becoming increasingly stringent for window manufacturers, many will turn to producing triple-glazed units to meet the new requirements.

When properly made, triples provide improved energy efficiency over double-paned units. However, production can often be problematic because of the difficulty achieving the proper temperatures in oven roll presses to provide a consistent seal to the center lite. To simplify production of triples, Edgetech I.G. offers the Super Spacer® Cushion Edge™ spacer system, which, like all Super Spacer products, eliminates the need for oven roll presses.

“When you use oven roll presses to produce triples you risk under-heating the center-lite seal, which can lead to premature seal failure in the unit,” said Larry Johnson, executive vice president of Edgetech I.G. “Super Spacer Cushion Edge features desiccant-filled, pre-applied side and channel adhesives, eliminating the need to apply sealant into two cavities and dramatically reducing the likelihood of seal failures.”

Super Spacer Cushion Edge is a flexible, U-shaped silicone foam spacer system that features a multi-layer vapor barrier backing and dual seal design for enhanced thermal performance and improved argon gas retention in triple-glazed IG units. With chamfered corners for increased sealant depth, Cushion Edge must be used in combination with conventional IG sealants, including hot melt butyl, polyurethane and solvent-free polysulfide.

Cushion Edge also provides a pleasing aesthetic appearance and improved productivity. The pre-applied U-channel assembly provides fast wrap-around, simplified production of shaped units, elimination of desiccant filling and corner key assembly for high-volume production with a small labor force.

“Some manufacturers will need to produce triples to meet the 2013 ENERGY STAR® codes,” Johnson said. “They should know there is an easier way to make triples with very little – if any – equipment investment. Cushion Edge provides the same no-metal benefits as other Super Spacer products with added advantages for producing triple-glazed units.”
