PerformaFlex Ultra features our R-Foam additive enhanced, radiant barrier covered, polyethylene foam within a 5” outer casing. R-Foam has 40% higher thermal effectiveness than standard polyethylene foam. R-Foam is covered with a highly effective radiant barrier.

Z-Supply is the only underground supply manufacture to give you the R-Foam advantage. We have it manufactured for us to our specifications and laminate the radiant barrier to it ourselves.

We have our heavy duty outer casing manufactured to our specifications at 264 grams per ft. The white outer pipe makes quality control here at the factory and on site far easier so you can rest assured in the integrity of your install.
