Installation Instructions

  • The InfraStop® Insulation is installed with the “white side” towards the interior of the building.

  • Pre-installation inspection - Check the roof area for clutter, water sprinklers, conduit and lights. Sprinkler systems are especially important. All water pipes must be below the InfraStop® to prevent the possibility of freezing in the winter.

  • Attach the product to the inside of the girts using 5/16” staples.

  • Tape the seams with a InfraStop® Foil Tape (goal is an air-tight, snug seam seal).
