Roof Insulation

  • by

POWER GUARD insulation is installed over and across the purlins, Aluminum foil (reflective surface) facing up. And the air gap tape is placed over the POWER GUARD foil along the purlins, fixed with reverts or self tapping screws to the purlin. This will create the required air gap between the foil and the roofing sheet to facilitate reflection of radiant heat once the insulation is covered with the roofing sheet.
