The ArmaTuff Plus, a super tough laminated insulation for exterior ducts, tanks, and vessels, can be used in all-weather applications. It is constructed with UV-resistant membranes that are laminated to sheet and roll insulation. A 13-ply reinforced fabric scrim makes the product resistant to tears and punctures. The ArmaTuff Plus has a zero permeability rating and, when installed properly, acts as an absolute vapor barrier. This product, which replaces ArmaTuff 25, comes with a 10-year warranty.
