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 variety of roofing materials.
Tectum IIIW Roof Deck panels are comprised of a 1-1/2-inch or thicker Tectum substrate, 3-to-8-inch thick extruded polystyrene (XPS) insulation, and 19/32-inch plywood sheathing with a slip-resistant surface. Components are bonded with code-listed structural adhesives. The Tectum substrate is composed of 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 pounds-per-square foot and can be used in high wind installations in either low or high slope applications. The panels can span up to 60-inches 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 percent 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 install with ease.
