Expanded Polystyrene (EPS) Roof Insulation is a lightweight, closed-cell foam insulation that is perfect for built-up roofing applications used in conjunction with exposed timber rafters. Built-up roofing methods allow for all the roof insulation to be fastened above interior ceiling decking and beams. This provides an effective alternative to conventional insulations materials such as fiberglass batts and blown rock wool. Our Nail Base EPS Foam Panels are manufactured pre-bonded with 3/8" OSB plywood sheathing.
Common Uses for EPS Foam Insulation Panels:
• Residential Built Up Roofing: Such as exposed beam ceiling configurations are an integral part of modern timber construction with exposed beams. The timber beams are placed first, followed by a layer of tongue and groove decking. From that point, a layer of foam panel insulation is applied replacing the need for conventional fiberglass batts or blown rock wool insulation.
• Commercial Built Up Roofing.
• Sidewall Insulation.
Features and Benefits Nail Base EPS Roof Insulation:
• Consistent R-Value - EPS Foam R-Values will stay consistent due to its exceptional stability and resistance to compression.
• Cost Efficient - EPS Foam Panels have a lower cost per R-value than many other insulation products, resulting in measurable energy savings over time.
• High Quality 7/16" OSB Sheathing - Nail Base EPS foam panels are manufactured with high quality OSB plywood sheathing pre-bonded to each panel using a high strength construction grade adhesive for a uniform, reliable, timesaving fastening surface.
• Dimensionally Stable - EPS foam panels remain dimensionally stable over the life of your roof and moisture has little to no effect on stability.
• Lightweight Construction - Ensures minimal weight on the roof and makes the panels easy to handle.
• Easy Installation - Each panel can be easily cut to fit, tightly joined together with other panels and fastened securely.

Storage of EPS Foam Insulation Panels Prior to Installation:
• EPS Foam Panels must be protected from exposure from the elements and must not be stored in direct ground contact.
• Set aside a level spot to store panels to ensure they will not lean or tip over.
• Lay panels flat on "sticking" lumber (such as 2x4's laid on their side) at least 3 inches from the ground.
• Place sticking lumber close enough together so that the panels will not sag, use 3 or more sticks if needed for longer lengths.
• Try to organize your panel delivery for efficiency (i.e. store panels from the first floor separate from panels for the second floor, and so on.).
• Mark individual panels so that you can identify panels for each specific place as you need them.
• We recommend moving and setting EPS foam panels with the help of at least one other person.
Fastening Nail Base EPS Roof Insulation: Exposed Beam Ceiling Built-Up Roofing
We recommend a flathead structural wood screw (such as a Headlok Panel Fastener) that passes through all the layers of roofing material to the beam. The screw should be measured to penetrate through each layer included in the insulation membrane and at least 2" into the structural beam. The insulation membrane typically includes OSB sheathing, the EPS foam panel, house wrap or vapor barrier, ceiling decking material or gypsum board and the interior beam. Be aware of where your beams or studs are to fasten into the middle of the beam. This ensures a strong point of anchor and to prevent potentially drilling through ceiling decking.
