How RoofingFoil™ + Underlayment Works As a Radiant Barrier in Metal and Tile Roofing Systems

Traditional roofing underlayments work to help keep your roofing deck and anything below it dry and free of moisture. RoofingFoil™ + Underlayment performs just like a traditional underlayment and meets or exceeds all of Miami-Dade County’s requirements for one. We’ve added a layer of our best-selling pure aluminum to the second side of this non-woven underlayment so when it’s installed in roof systems with an air space, it can block 97% of radiant barrier. This foil insulation plus underlayment is all you need!

  1. I attached radiant barrier to the rafter front, creating a 3-3/4″ air gap. I removed the soffit blocks and with the ridge vent a continuous air flow exists between the soffits and ridge vent. Do I need more ventilation?
    Thank you.

  2. Can I put this product between two layers of plywood roof sheeting and then install a cold rolled asphalt roof to help reduce heat radiating down? This is for a screened porch application.

    1. Nope, it doesn’t work like that. Putting any radiant barrier between 2 other materials makes it void as a radiant heat shield – it can’t block any heat that way. You must have at least a ½” air space on one side of the foil between the foil and the next layer.
