3. Thermal Performance
One of the main reasons homeowners purchase new windows is for improved energy efficiency in their homes. While it’s a hidden component of the overall window, the spacer is an extremely critical component in ensuring the window’s thermal performance.
When it comes to thermal performance, the Intercept® spacer and foam spacers are equal. However, a myth being propagated by foam spacer manufacturers is that metal spacers lead to poor thermal performance in a window. Using scientific evidence and thermal imaging technology, it has been proven that Intercept® stainless steel spacers are just as effective as foam when it comes to thermal performance.
Compare the two images. The first is a thermograph or “heat picture” of a window manufactured with the Intercept® Spacer System. The second is a thermograph of a window manufactured with a foam spacer. There is very little difference in these images. Why?
When measuring the U-value of each window–a measure of the insulating characteristics of the total window unit–both values are equal. In fact, you have to go three places beyond the decimal point to spot any difference at all.

What good is a window if it doesn’t keep the elements out? In the “Thermal Performance” video, Glenn the Glass Guy uses a thermal imaging camera to compare the insulating value of a window with the Intercept® Stainless Steel Spacer to a window with a foam spacer.
