Polar Fold Protection Board
Protecting a foundation from backfill is crucial to the integrity of sheet membrane or liquid applied waterproofing. Aggregates in the backfill can puncture the membrane and reduce the effectiveness of the waterproofing. Polar Fold is strong, yet lightweight, making it ideal protection board for below grade applications.
Polar Fold is not affected by chemicals or moisture and serves as insulation when the project requires below grade applications. Polar Fold is manufactured with a rigid EPS insulation core and wrapped with tough polypropylene facers and is used for protection in both vertical and horizontal applications. Higher insulation values can be achieved by specifying Polar R.
Available in 4' x 50' sheets and comes in 3/8" and 1/2" thickness.
Benefits
Insect Resistant
Polar Fold can be treated to resist the infestation of termites with Perform Guard treatment. Perform Guard is made under a patented process that uses a natural mineral that is formulated to resist termites and is a safe EPS regulated additive. Consult ACH for more information.

Caution: EPS contains a flame retardant; however, it should be considered combustible and not exposed to sources of ignition
EPS core is manufactured to meet the requirements of ASTM C-578 and is listed under ICC 1006. Consult ACH for current code compliance.

Installation Instructions
1. Polar Fold/Polar R is compatible with various sheet and liquid applied waterproofing. Consult the waterproofing manufacturer for specific approvals.
2. Polar Fold/Polar R should be applied on a vertical surface with an adhesive that is compatible with the EPS insulation. Do-all-ply adhesive or equal is acceptable for the adhesive application over vertical surfaces.
3. Care should be taken to tightly butt all protection board joints.
4. Prior to backfill all material needs to be inspected to insure that all waterproofing is properly protected before proceeding with backfill. (consult the waterproofing manufacturer for specific instructions)
5. Horizontal surfaces can be protected with Polar Fold/Polar R protection board. All material needs to be laid loosely and all joints should be tightly butted prior to finishing. (consult the waterproofing manufacturer for specific instructions)
