These ratings are average values obtained in accordance with accepted test methods. Superlon products perform best within the operating temperature range. Out of this temperature range, Superlon materials become increasing harden & brittle. However, this hardening characteristic does not affect thermal insulation or water vapour permeability abilities. The fire rating method of tests conducted under controlled laboratory conditions is a measure of a material to contain flame or heat , & is not intended to reflect hazards presented by this or other material under actual fire conditions.
