•

The above average physical properties are values obtained in accordance with accepted test methods.

 
•

At -40°C, Insulflex Closed Cell Insulation becomes hard and as temperature drops below -40°C will be increasingly brittle; however this hardening characteristic does not affect thermal or water vapour permeability.

 
•

The Fire Rating standard method of tests conducted under controlled laboratory conditions is a measure of a material to spread flame when compared to a known standard and is not intended to reflect hazards presented by this or any other material under actual fire conditions.
