There are many factors to consider when it comes to designing a roof system, but one key product that is often overlooked during a project is the roof cover board.
Cover boards are crucial in the long-term protection of a building. The cover board serves as a critical component that helps extend the life of a roof because, without one, the roof lacks added durability and protection, making it more susceptible to impact, hail, fire, and wind damage throughout the lifecycle of the building.
A cover board is a substrate that is installed over the insulation and under the membrane in a commercial roof system. They have been recommended in commercial roofing since the 1950s but are not widely used in the industry outside of high-performing buildings, which include schools, data centers, hospitals, airports, and government buildings.
Cover boards provide added protection and durability to the insulation as well as the entire roof system, allowing the roof to last longer. Extreme weather can lead to leaks that can impact the operations of high-performing buildings, and cover boards can help prevent any unplanned repair costs.
Extend the life of the roof by protecting its insulation from hail, equipment, and foot traffic.
Excellent fire performance that acts as a thermal barrier to improve building efficiency (FM Class 1 and UL Class A per UL 790).
Achieve superior wind uplift ratings with high compressive strength and fewer fasteners for a wide variety of roof systems.
Over the years, the construction industry has collected more detailed information about roofs and how storms and normal maintenance can damage a roof. To combat this issue, USG offers a range of roof cover boards manufactured with properties that make them stronger from the outset, leading to an increased roof lifespan and securing the reputations of all project stakeholders, from contractors to building owners.
