The ACH Foam group of film laminated EPS is called Polar-R, 4ft. x 8ft. panels, and Polar Fold, 4 ft x 50 ft bundles. Our Polar products are commonly used as a wall leveler for residing or sheathing applications, a roof recover board, below-grade insulation for both perimeter wall and underslab, and as protection for waterproofing materials. An added benefit available with all Polar products is a reflective facer which, according to ASRAE when applied allowing a ¾” dead airspace, allows for a 2.1 gain in R-value.
Polar-R (4 ft. x 8 ft.) or Polar Fold (4 ft. x 50 ft. fan fold sheets) when used as a wall leveler for residing applications will help to provide a flat and level surface for new siding along with the added benefit of more insulation. Polar-R or Polar-Fold wraps your home in a continuous insulation that reduces air infiltration and gives you a lifetime of energy savings. Use Polar tape on all the seams to reduce air infiltration even more.
Polar Fold Roofing recovery board is a favorite among designers and contractors for re-roofing applications. The film facers of Polar Fold or Polar-R are engineered to be compatible with single ply ballasted and mechanically attached roof systems alike, without the use of additional slip sheets.
Below grade insulation – perimeter wall and underslab: In many places around the country well-insulated foundations are required. Polar-R’s high R-Value and tough film facings provide for an ideal below-grade insulation helping to prevent heat loss through the foundation. This application will also protect the foundation’s sheet membrane or liquid-applied waterproofing. Both the facers and the expanded polystyrene core are not affected by chemicals or moisture.
All Polar products are available in a variety of compressive strengths, from 5 psi to 25 psi, to best serve any of your construction needs. In addition, Polar-R and Polar Fold allow for less than 1% water absorption and has a flame spread index of less than 25 and a smoke-developed index of less than 450.
