Tectum® IIIW Roof Deck panels from Armstrong Building Solutions are now Miami-Dade NOA (Notice of Acceptance) approved. Ideal for use in hurricane prone areas, the three-in-one composite panels provide sound absorption, insulation, and a nailable surface that accepts a wide variety of roofing materials.

Tectum IIIW Roof Deck panels are comprised of a 1-1/2" or thicker Tectum substrate, 3-to8-inch thick extruded polystyrene (XPS) insulation, and 19/32" plywood sheathing with a slip-resistant surface. Components are bonded with code-listed structural adhesives. The Tectum substrate is composed of rapidly renewable and FSC-certified aspen wood fiber and contributes to LEED® V4 criteria.

High Wind Uplift Resistance

The panels have a wind uplift resistance of up to 321 lbs/sq ft. and can be used in high wind installations in either low or high slope applications. The panels can span up to 60" and feature a 50-pound design load and a diaphragm shear of up to 786 dsn/lf. In addition to wind resistance, the panels have a Noise Reduction Coefficient (NRC) of up to 0.60 indicating they absorb 60% of the sound that strikes them, thereby providing predictable acoustics. They also feature a thermal insulation R-value of up to 44 and a textured interior finish that can be painted up to six times without affecting acoustic or fire properties.

By providing noise absorption, insulation, and a nailable surface in one panel, Tectum IIIW Roof Decks are much faster and easier to install than the multi-step installation of acoustical steel deck systems.
