Super Spacer® - TrueWARM® Edge Technology

Clearly, the Super Spacer product line stands alone. We call it TrueWARM because Super Spacer is the world's only 100% polymer foam, NO-Metal Warm Edge spacing system. Its arrival on the scene in 1989 revolutionized the insulating glass industry, and today, this TSS® technology is still breaking new ground in providing the warmest, longest-lasting windows anywhere in the world.

The NO-Metal Advantage
"Thermal efficiency through no presence of conductive metals" is Super Spacer's hallmark. The edge of the insulating glass unit is indeed the most vulnerable to heat and cooling loss, window condensation and frosting. Super Spacer's NO-Metal formula blocks the heat escape path and provides one of the best thermal performances in the industry. That means it keeps the heat in during the winter months and keeps the cool in during the summer months. Super Spacer assures comfortable winter humidity levels with hardly any worries about condensation and mold.

Warmest Possible Edge - leads to best thermal performance.

In order to keep window condensation moisture off the glass, your window needs to have the warmest inside surface temperature possible. The all-foam formula in Super Spacer®, used to separate the panes of glass in your windows, conducts less heat and cold than conventional metal spacers, providing the warmest possible edge.

Low-E coatings:
Optional Low-E glass coatings help reduce heat transfer and UV rays that can fade carpets, walls and furniture.

Argon-filled glass:
Argon gas is an odorless, colorless, tasteless, non-toxic gas that is six times more dense than air. It is used to replace air between the glass panes to reduce temperature transfer. Super Spacer® loses less than 1% of Argon Gas. INDUSTRY'S MOST CONSISTENT SEAL FOR ARGON GAS RETENTION.

Energy efficiency:
Many Best Window products meet or exceed the Department of Energy's ENERGY STAR® standards. That energy-efficient performance can mean substantial savings on your heating and cooling bills.
