What is Warm Edge Technology?
Today more than ever, homeowners are replacing their old worn out windows with energy efficient replacement windows. Poorly insulated windows can attribute to 25 percent of a building’s heating and cooling loads. As a homeowner, it is just as important to know what type of window spacer material is being used on the insulating glass unit as it is to know what type of glass package (or glazing) is going into the window. The type of spacer material in your windows can make or break your investment!

In order to overcome the thermal inefficiency of conventional aluminum spacers, a new type of spacer product called warm-edge technology has evolved in the industry. Warm-edge refers to the type of spacer material used to separate the panes of glass (or glazzing) in an insulated window unit. If the material conducts less heat or cold than a conventional aluminum spacer at the edge of the glass, it is said to be ‘warm-edge.’ Most of these newer spacers are less conductive and outperform pure aluminum. But there’s still one small problem-- they all contain some kind of metal. And metal is highly conductive.

Why is Super Spacer better?
Super Spacer - The NO-Metal Advantage
Super Spacer is a True Warm™ edge technology product because it is the world’s only all-foam, NO-Metal spacer on the market today. Unlike other so-called "warm" edge seal spacers that contain steel or aluminum wrapped in butyl rubber, Super Spacer is made of 100% polymer structural foam. “Thermal efficiency through no presence of conductive metals” is Super Spacer’s hallmark. Super Spacer’s NO-metal formula blocks the heat escape path and provides one of the best thermal performances in the industry. Super Spacer assures comfortable humidity levels with hardly any worries about condensation and mold.

How long will Super Spacer last?
Windows that Last a Lifetime
Super Spacer is made with Thermoset Spacer (TSS) technology. This technology ensures that the spacer will expand and contract, but it will always maintain its structural integrity by returning to its original shape.

This is very important because windows are constantly exposed to temperature changes, UV ray bombardment, barometric pressure changes and wind load. Other rigid spacers containing metal do not allow for the natural expansion and contraction that must occur in the insulated glass unit to offset the effects of these pressures on the glass. The results are stress cracks that eventually lead to seal failure.

Super Spacer is a dual-seal system that uses a high-performance acrylic adhesive for its structural seal. Backed with a moisture vapor seal, Super Spacer insulating glass lasts five times longer in durability tests than single seal units. The results are obvious. Super Spacer structural foam combines with this acrylic adhesive strength to form the most reliable primary seal in an insulating glass unit on the market.
