Reliable Performance and Durability

Tectum Replacement offers a wide range of panel options for contractors, including Tectum III and Tectum IIIP – three-in-one panels designed for acoustical performance, excellent insulation, and a wide range of applications.

What Is Tectum III?

Tectum III roof deck panels are available in spans up to 8 feet and in a variety of thicknesses. Each thickness features XPS insulation layered between Tectum substrate and OSB for high-quality performance. With a slip-resistant surface, Tectum III panels are suitable for sloped applications requiring insulation, easy installation, and a nailable surface.
