Having the best glass options in the industry isn't enough unless it is packaged with the best insulating system on the market. Our Super Spacer is a true warm edge spacer and is a specially engineered, all foam, NO-Metal technology. Super Spacer is a true dual seal warm edge spacer system that uses a high-performance acrylic adhesive for its structural seal, backed by a moisture vapor seal.

Super Spacer Glass Options

Two seals are better than one

This is proven by the fact that windows made with Super Spacer last five times longer in durability tests than single-seal units.

Super Spacer Windows


Unlike metal spacers, Super Spacer can bounce back when put to the test against winds, temperature fluctuation, rain, snow and UV light. The foam construction of Super Spacer allows it to expand and contract as need, but always returns to its original shape. Without Super Spacer's 100 percent memory formula, windows can eventually crack and lead to seal failure.

Thermal Performance

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 in much the same way.

Unlike metal-based spacers, the all foam construction of Super Spacer is non-conductive, blocking heat flow through the window. By blocking the heat escape path, Super Spacer provides one of the best thermal performances in the industry.

Minimal Condensation

This reduces condensation and freezing of water at the edge of our windows.


Mold Prevention

The fact that Super Spacer is non-conductive means that it also protects a major household threat, mold. Window condensation can lead to molds that increase the likelihood of allergens, including fungi, viruses and mites that might cause respiratory infections, allergies and asthma.

Mold needs moisture to grow. To keep condensation off of glass, windows need to have the warmest inside surface temperature as possible. The world's warmest edge occurs with Super Spacer.

Sound Absorption

The closed-cell polymer foam in Super Spacer transmits very little sound compared to conventional metal spacers. Another reason you're more comfortable at home with Super Spacer.


An independent study found that Argon gas I.G. units made with Super Spacer lost less than 1% in five years in both Accelerated Weather Cycling and High Humidity test. The Mylar vapor barrier film serves many purposes. Among them, it helps keep moisture out and the gas in.
