EnergyGuard™ HD & EnergyGuard™ HD Plus Polyiso Cover Board

EnergyGuard™ HD and EnergyGuard™ HD Plus have an R-value of 2.5, higher than any non-polyiso cover board. And at 11 and 13 lbs. per 4’ x 8’ board, it’s a fraction of the weight of gypsum cover boards. These boards are made with a high-density polyiso foam core and durable coated glass facers (CGF), making them the ideal board for protecting your roof against the elements, moisture, and traffic.
