1 R means resistance to heat flow. The higher the R-value, the greater the insulating power.
2Vertical compressive strength is measured at 10 percent deformation or at yield, whichever occurs first.
3Based on 1” (25 mm) thickness.
4These numerical flame spread and smoke developed ratings are not intended to reflect hazards presented by this or any other material under actual fire conditions.
5Tested at 158°F/97% RH/7 days.
