Roof Talk-101 The Top 5 Reasons Commercial Roofs Need Cover Board
Roofs are more important than ever. They support sustainability efforts, host tons of equipment, promote energy-efficiency and are the first (or last) line of defense from the elements.
So cover boards are a must to get the most out of your roof. Here’s how.
- 1. Fire Resistance
The right cover board can enhance a building’s ability to withstand and mitigate the effects of fire – especially if the insulation, decking or membrane is combustible. Make sure the cover board you use is UL Class A rated, and has met or exceeded ASTM E136 testing standards. Many commercial roof assemblies use a fiberglass mat gypsum panel as a thermal barrier against the deck AND as a cover board under the membrane, which increases the total fire rating of the assembly. - 2. Insulation Protection
- As the most expensive component in the roof assembly, you’re spending more money than ever on insulation as a key component in meeting a building’s energy goals. So the insulation needs to last. Rigid cover boards with good compressive strength resist impact loads, extending the life and performance of the insulation layer and the total assembly.
- 3. Wind Uplift Protection
Look for a cover board with enough strength to prevent wind uplift when installed between the membrane and insulation, and that can keep metal fasteners from loosening during harsh conditions. - 4. Sound Resistance
Effective cover boards can help attenuate outside noise and significantly raise the Sound Transmission Class (STC) of the roof assembly. Some have been proven via third-party testing to increase sound reduction. - 5. Strength and Durability
Cover boards are an effective means of protecting the membrane, insulation and decking from puncture, crushing and other effects due to hail, foot traffic, HVAC and other equipment installation and maintenance that can take a toll on a roof.
Gypsum cover boards with fiberglass mats, like DensDeck® Roof Boards from Georgia-Pacific Gypsum are especially effective in addressing these and other roofing needs.
