Q:Does the box have facing on the inside, or is it bare fiberglass?
by|Nov 25, 2023
1 Answer
Answer This Question

A:  Ductboard is designed with one side batre and one side faced. When properly put together the facing will be on the outside and the bare ductboard on the inside. If you have any inquiries about Master Flow products please email MasterFlowTech@gaf.com

    Q:Although there is a shiplap groove, there isn't a flap of the paper-backed foil in which to wrap over the edges to create the seal. Covering that exposed insulation with foil tape won't that cause condensation to form?

    1 Answer
    Answer This Question

    A:  Not if sealed properly and the shiplap is tight.

          Great product
          worked great for what I needed, glad it was not assembled would have been hard to use, worked best for me to assemble it myself for what for what I needed ,cheaper than buying duct board and a cutting tool.

              I agree with previous reviews. The triangle pieces don't have vapor barrier extensions, and when bending the triangle piece closed, you must cut the inner insulation so that the outer vapor barriers of the open ends meet. That might leave some uninsulated space inside if you don't cut it exactly right. The ends are cut at 90 degrees, not at the proper angle for the open ends of the triangle to meet when folded.
