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 window spacers, a new type of spacer product called warm-edge technology has evolved in the window industry. Warm-edge refers to the type of spacer material used to separate the panes of glass (or glazing) 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 window 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.

Super Spacer® -- No Metal Advantage

Super Spacer is a TrueWARM® 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 reduction of worries about condensation and mold.

Health Smart Windows

In order to keep window condensation moisture off the glass, your windows need to have the warmest inside surface temperatures possible.

The world's warmest edge occurs with Super Spacer an insulating foam spacer whose use assures comfortable household humidity levels with the least likelihood of mold and other problems.

Super Spacer blocks the heat escape path and provides one of the best thermal performances in the industry. But most importantly, Super Spacer®eliminates concerns about harmful mold and protects your family - your most precious possessions.
