Permanent R-Value Guarantee

The thermal resistance of this type of insulation is permanent due to its cellular structure which contains only stabilized trapped air. EPS performance does not diminish over time.

Installation

Insulation panels can be applied hot or cold, as needed, using bitumen cooled to 225°F or fixed to the surface mechanically.

Evaluation

Conforms to CAN/ULC-S701-01 standards
Conforms to CAN/ULCS-126M DSIGN C7,C12
Conforms to Association des maîtres couvreurs du Québec standards

Notes

EPS beads should be considered flammable when subjected to a source of intense heat or a constant strong flame. They are vulnerable to petroleum-based solvents and prolonged exposure to ultraviolet radiation.
