Versatility of Film Faced EPS Insulation

By:  Doug Wehrwein, Sales Representative – Architectural Products

The ACH Foam Technologies line of film laminated EPS is called Polar.  There are two types of Polar products:  1. Polar-R® a 4 ft. x 8 ft. flat sheet of insulation and 2. Polar Fold® a 4 ft. x 50 ft. fan fold sheet of insulation.

The durable facers laminated on each side of the EPS insulation help to make these products easy to use, even in undesirable weather conditions.  Polar-R® and Polar Fold® wrap your home in continuous insulation which reduces air infiltration and gives you a lifetime of energy savings.  

Polar-R® & Polar Fold® Installation Tips:

Tape the seams of both products with Polar Tape to reduce air infiltration and ensure maximum performance of the insulation.  Also use a wall lever for residential siding applications to help provide a flat and level surface for new siding.

Polar Fold® for Roofing

Polar Fold® Roofing recovery board  is a favorite among designers and contractors for re-roofing applications.  The film facers of Polar Fold® are engineered to be compatible with single ply ballasted and mechanically attached roof systems without the use of additional slip sheets.

Polar-R® Below-Grade Insulation

Below-grade insulation; specifically, perimeter wall and underslab insulation is used in many places around the country to create a well-insulated foundation. Polar-R’s high R-Value and tough film facings make it an ideal below-grade insulation for preventing foundation heat loss.  Polar-R below-grade insulation is available in 4’ x 8’ sheets and comes in thicknesses of: ½”, ¾”, 1 ½”, 2”, 3” and 4”.

Polar Fold® Protection Board

Polar Fold® Protection Board protects a foundation from damage due to backfill and is critical to maintaining the effectiveness of either sheet membrane or liquid-applied waterproofing.  Polar Fold® is strong yet lightweight, making it the ideal protection board for below-grade applications.  The expanded polystyrene core of Polar Fold® is not affected by chemicals or moisture and it adds thermal protection.  Polar Fold® is available in 4 ft. x 50 ft. fan fold sheets in 3/8” and 1/2” thicknesses.  Higher R-Values can be achieved by specifying Polar-R which is available in greater thicknesses.

Polar-R® and Polar-Fold®, like all ACH Foam Technologies’ EPS products , are environmentally safe and contain no CFCs, HCFCs, HFCs or formaldehyde.
