The main part of our window's superiority is our unique spacer.

Think about what windows go through. They have to face extreme temperature changes all year. Plus, they're bombarded with UV rays, barometric pressure changes and nasty winds.

Luckily, there's a simple way to give your windows an advantage in reducing energy costs, ensuring durability and adding comfort and value to your home. It's foam - a unique formula we call Super Spacer^®.

Many of today's energy efficient windows offer glass packages with "Warm Edge Technology." The problem is that highly conductive metal-based insulating glass spacers are often used in these new windows.

Our NO-Metal, all foam formula blocks heat flow, unlike most metal-based spacers on the market today. Windows lose and gain heat by conduction, convection, radiation and air leakage. Conduction is the movement of heat through a solid material. Touch a hot skillet, and you feel heat conducted from the stove through the pan. Heat flows through a window much the same way.

While windows sealed with Super Spacer protect you from the foul weather beating on your house, there's something else they keep outside - noise. That's because the closed-cell polymer foam in Super Spacer transmits very little sound compared to conventional metal spacers.

Hospitals and museums use Super Spacer^® because it dramatically reduces condensation, discouraging the growth of mold and bacteria.

Metal can't bounce back the way Super Spacer can. Thanks to its Thermoset Spacer technology, the spacer will expand and contract, but it will always return to its original shape. Rigid metal and plastic spacers cannot compensate for the natural expansion and contraction that occurs daily in insulating glass. Without all-foam Super Spacer, windows can develop stress cracks that eventually lead to seal failure.

If only the strong survive, then we'll outlast all the rest. All Super Spacer products meet the challenge of the P-1 chamber, the test many engineers consider the worlds toughest. One week spent in a P-1 chamber is equivalent to one year in the field. And since Super Spacer survives 100 weeks, well, you do the math.
