Does the Spacer Really Matter

Does the spacer really matter? Absolutely.

Before we explain what Super Spacer® is, let’s take a big step back – what is a spacer? A spacer is the component, or piece, used in window manufacturing that separates and seals the two panes of glass in an insulating glass system. Its intent is to insulate your windows to help maintain an ideal temperature during the seasons you heat or cool your house.

Historically, spacers commonly contained metal, which manufacturers thought provided more durability for their windows. However, what happens with a metal spacer – even one containing aluminum – is that it acts as a conductor. In other words, the metal acts as a catalyst to the very thing it was trying to prevent.

In 1989, Edgetech revolutionized the window industry with the introduction of its Super Spacer, featuring TrueWARM® edge technology. Super Spacer was the world’s first 100 percent polymer foam, NO-Metal warm edge spacer system. Even today, Edgetech continues to drive product innovation as Super Spacer still serves as the benchmark for quality in the insulating glass industry.

So when you’re buying new windows, don’t forget to ask what type of spacer is used. It can make all the difference in the long-term durability, energy efficiency, mold prevention and sound transmission. Windows are a big investment. Be sure to invest wisely with Super Spacer.

Super Spacer Facts:

  • More than a billion feet of Super Spacer has been sold worldwide.
  • Super Spacer has a better U-Value than spacers that contain metal, meaning less heat passes through the window.
  • Windows made with Super Spacer outlast the rest in the industry’s toughest test for durability, the P-1 chamber – lasting up to 125 weeks.
  • Experts estimate that one week in the P-1 chamber is approximately equivalent to one year of service, so Super Spacer can last up to … well, you do math.
  • With Super Spacer, condensation is virtually eliminated.
