      Answer This Question

      A:  I guess you could but keep in mind it’s insulation. 

      by|Apr 17, 2022

        A:  It is very straight and not bendable. But it is basically like a giant piece of dense styrofoam with paper over it to make it smooth.  You can definitely attach posters or other things to it and stand it. I would not be pressing hard on it because even though it is firm, it is styrofoam.  We draped a large mural over it for display and it worked great.

            A:  Polyiso has the highest R-value per inch installed. Home Depot, carries R-Matte Plus-3 and Thermasheath. Either will work in this situation but I would recommend at least 1" thickness for increased board stiffness. Once the board is well secured with screws and washers or cap nails, use a construction tape to seal all edges of the board but make sure to use a hard plastic squeegee to firmly press the tape onto the board! This will help reduce air leaks through the assembly.

              A:  Your insulation technique will depend on many factors including moisture/water permeability. Check with the Pros at Customer Service in your local Home Depot for options and inventory.

              A:  what rating are you looking for, varies from 1/2" to 3"? you will need to have some vents to prevent humidity build up and mold problems
