Polar Fold® Roofing ReCover Board
About Polar Fold® Roofing ReCover Board
Polar Fold® is a high performance Roofing ReCover Board consisting of light weight, energy efficient, expanded polystyrene (EPS) laminated between strong film facers. Polar Fold® Roofing ReCover Board is the preferred solution for re-roofing applications among architects and contractors and is compatible with single ply ballasted and mechanically attached roof systems.
Polar Fold® offers energy efficiency, water resistance and versatility. Polar Fold® is easy to handle and install, saving time and labor. The innovative fan fold design insures Polar Fold® lays flat during installation providing a level surface for roof membranes.
Polar-R® is also available for roof applications and comes in 4' x 8' sheets in 1/2" to 4" thicknesses and is manufactured with the same quality materials as Polar Fold®.
Benefits of Polar Fold® Roofing ReCover Board
Labor Savings & User Friendly
Polar Fold® is available in 4' x 50 fan fold sheets that arrive in compact, light weight bundles, making it easy to handle and install. The 50 foot length of Polar Fold® speeds installation time. Polar Fold® is designed to lay flat during installation, eliminating seam welding problems experienced with other fan fold insulations.
Durable and Water Resistant
Polar Fold's high performance EPS is wrapped in tough film facers making it durable and water resistant. Polar Fold® has low water absorption and rate of permeability which makes it a superior product for re-roof applications. The film facers allow single ply membranes, including PCV, to be installed directly over Polar Fold® without additional slip sheets.
Cost Effective Precision Performance
Polar Fold® is less expensive than other re-cover products and provides more R-value for less money. High performance EPS insulation also has a consistent long-term R-value that does not experience thermal drift. EPS has a 35 year history of proven performance in the roofing industry.
Energy Efficient and Environmentally Friendly
Polar Fold® improves thermal performance of recover applications. Contains no ozone depleting agents, is made with recycled materials and is a component in LEED certified projects. Available with a 50 year R-value warranty.
Installation Recommendations
The substrate should be flat, dry and free of any foreign materials that would damage the Polar Fold® insulation board. Beginning of installation indicates that the contractor has accepted the condition of the existing substrate. Some membrane manufacturers will require a higher concentration of fasteners. Consult membrane manufacturer for installation instructions. One fastener is placed at each corner of the leading and trailing edges of Polar Fold®. One fastener is placed every 12 feet on altering sides of the sheet thereafter. When used with dark colored membranes, Polar Fold® should be installed with the reflective side up.
