Q:I’ve a vented attic. like to nail these to the underside of my roof rafters to maintain airflow for the roof, but to seal off the attic from the vented roof air. My Q, for a shingleroof,does the white side face up, does hot heat from roof affect the foam?

Answer This Question

A:  Hello Butler, The service temp for this product is 250 degrees. Heat from the roof should not affect the foam. Either side facing the exterior is fine.

      Favorite of carpenter ants
      Think twice before using a polyiso-based foam product in any application that might be exposed to carpenter ants, as this stuff makes an ideal nesting material for them. Installed it in a camper build I am doing - even with the exterior complete and elevated a foot off the ground - left alone for a month, ants found their way in and set up shop in this foam. I had to completely rip up the new plywood floor and remove hundreds of ants and eggs (see photo). 'Below-grade approved'? How??

          Easy to cut and didn't make a mess. Used it for my garage door and didn't break when I slightly bent it during installation. Cut the temperature down at least 10 degrees since my garage door faces south.

          I used the board to outline the floor of my John boat. I found out from b 4 that it is water and weather proof. The plywood was worn out and i ralized it was 2 heavy. I came up with the idea to usr the foam board. I cut it 2 fit n between the ridges and use l clamps 2 hold it down. It really made me believe thst it csn b used 4 more than you think.

          Installed under sheet metal deck roof. Effectively keeps the deck cool in direct sun and prevents condensation from wetting the framing and deck.

          Very deceptive. I live 2 hours away and purchased the item online and then drove to pick the item up. The way it is listed it certainly appears the borders is 3&1-2in board, I know this is not just my stupidity because when I went to pick it up the customer service person made the same analysis. certainly would not have driven 2 hours for 1/2in thick board.

          Made a great Design Board!
          Used two boards and taped them together with duct tape, stood them up and pin my quilt fabrics to them so I can see my design before sewing it! Works out great!
