The Groupe Legerlite certifi es that this product conforms to the CAN/ULC-S701 (Intertek) standard.

Ultraviolet degradation

Prolonged exposure to ultraviolet rays will produce slight discoloration and crumbling of surface. Insulation properties will be reduced minimally unless exposure is long enough to reduce thickness. To avoid ultraviolet degradation, cover block as soon as possible.


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