DensDeck® Roof Boards

- Versatility for Commercial Roof Systems

Versatility for Low-Slope Roofing Systems

The push for energy efficiency and sustainable construction makes it more compelling than ever to specify versatile, DensDeck® panels in today's low-slope roofs. DensDeck panels have the ability to protect the structural deck and insulation, to isolate noise under a variety of membranes - and DensDeck provides the most effective thermal barrier of any conventional roofing underlayment.

DensDeck for sound remediation

Sound Remediation

DensDeck® Prime Roof Board adds a high-mass component to the roofing assembly that can help block unwanted noise. In new construction or in retrofit applications, DensDeck enables an innovative solution for exterior sound remediation.

Vegetative, Photovoltaic (Solar) and Cool/Reflective Roof Systems

DensDeck roof boards meet the stringent requirements of innovative roofing technology. These fiberglass mat gypsum panels contribute strength and stability to roofing systems that support heavy alternative energy equipment and increased foot traffic during installation and maintenance. As a substrate or cover board, DensDeck can support the membrane and protects the more fragile thermal insulation layer from damage.

Enhance Structural Deck Performance

Whether the structural deck is wood, steel or concrete, DensDeck® roof boards can help manage the unique challenges that each one presents. They provide a superior thermal barrier for wood decks. For corrugated steel systems, DensDeck provides a flat, rigid surface for fasteners and adhesive. For concrete decks, DensDeck provides a uniform underlayment for adhered systems.

DensDeck protects insulation

Protects All Types of Insulation (ISO, EPS, Fiberglass)

DensDeck can help extend the average lifespan of a roof by protecting the insulation. No matter how tough the insulation is, without a cover board it may still be compromised over time by maintenance traffic, impact from hail and other stress factors.

DensDeck for membrane roof systems

Adds Performance for All Membrane Roof Systems

For all membrane types - built-up (BUR), modified bitumen, single-ply or self-adhered - versatile, durable DensDeck roof boards add performance to the roof system and add puncture resistance. Recommended as a thermal barrier and as a cover board, DensDeck can help the roof perform better over time.
