Tectum Decking

Tectum roof deck offers solutions to three problems facing architects in the design of large public buildings, such as gymnasiums and natatoriums: thermal, acoustical, and structural.

Manufactured from aspen wood fibers and bonded with exclusive inorganic, hydraulic cement, Tectum roof decking is then formed into a panel through a continuous application of heat and pressure.  The resulting Tectum panel offers highly desirable characteristics, including increased insulation, excellent sound absorption, and a decorative, textured, interior finish.  Previously, it required several separate materials to obtain the results offered by the Tectum panel.

Tectum is a structurally sound panel that, by itself, or as the underside of a composite panel, forms a roof deck system with limited combustibility.  A silicone treatment applied to the panel provides resistance to water and water migration.  And, there is no urea formaldehyde, asbestos, or CFCs in any Tectum product or composite.  WWS distributes this product in the northwestern United States.

Tectum roof deck was used in the remodeled Tigard High School Commons.  The glulam trusses were fabricated and assembled in the WWS shop.


WWS designed these 50' span glulam trusses and pre-assembled them in our fabrication shop. WWS also supplied the 9" Tectum "E" roof panels which serve as both a structural and an acoustical panel.
