LANCASTER, Pa. — 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-inch or thicker Tectum substrate, 3-to-8-inch thick extruded polystyrene 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 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 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 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.
