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¡ãF/97% RH/7 days.
