Can Your Replacement Windows Survive the P1-Chamber Test?



The National Fenestration Rating Council (NFRC) developed the P1-Chamber to rigorously test the quality and durability of replacement windows and their components under extreme, all-weather conditions. Test after test, vinyl replacement windows featuring SuperSpacer® technology from Universal Windows Direct outperformed the competition.

Here’s how the testing works:

  • UV-Ray bombardment for 24 hours a day, 7 days a week

  • Constant 100% relative humidity inside the chamber

  • Continuous temperature variations from 140 degrees Fahrenheit to -30 degrees Fahrenheit

  • One week in the P1-Chamber is equal to one year in the field

Why SuperSpacer® is Better:

In replacement windows, a spacer separates the panes of glass and serves as a barrier to the inert gas filling. Most spacers within the industry are made of metal which permits heat loss by conduction and are prone to seal failure. By contrast, SuperSpacer® technology contains no metal. Its patented, all-foam construction yields improved insulation, superior durability and greater overall performance.

The Results:

Unlike the competitors which failed in as little as 3 years, the patented, all-foam SuperSpacer® survived the brutal P1-Chamber for the real-world equivalent of 125+ years!

  • Limited Vibrations
  • Moves with thermal expansion and contraction
  • No seal disruption
  • No internal condensation
  • No mold growth or allergens
