Polar-R® EPS was developed to meet all of these requirements and incorporates high performance EPS insulation with strong film facings, making it a durable underlayment for the application of new sidings. The Polar-R® design wraps your home in a continuous insulation envelope that reduces air infiltration and gives you a lifetime of energy savings.

Polar-R® EPS is available in 4’ x 8’ sheets and comes in a range of thicknesses: ½”, ¾”, 1 ½”, 2”, 3” and 4”.

• Superior Moisture Resistance
• Continuous Level Surface
• Energy Efficient
• Less Cost Per R-Value
• Durable and Strong
• Easy to Handle and Install
• Termite Resistant
• Environmentally Friendly
  • Polar-R® contains no CFCs, HFCs, HCFCs or formaldehyde and is available with a 50-year R-Value warranty.

• The substrate should be flat, dry and free of any foreign materials that would damage the insulation board.
• Beginning installation indicates that the installer has accepted the condition of the existing substrate.
• Install Polar-R® EPS directly over existing substrate using galvanized or aluminum roofing nails. Remove any damaged siding and install directly over framing members if necessary.
• Avoid over driving fasteners, because this will compress the insulation and create a wavy appearance of the new siding exterior. The installer should be careful when installing under new siding materials.
• The board must lay flat and be adequately fastened.
• Install new siding directly over the Polar-R® per the siding manufacturer’s recommendations.
• A higher R-Value can be achieved by using ½” furring strips between the existing substrate and the Polar-R® reflective surface. (Consult the R-Value chart for more information.)
