1 Specimens are aged and tested in accordance with FTC Rule (16 CFR, Part 460) and ASTM C578.
2 Permeance shown is for 1” thick board. Permeance typically decreases as board thickness increases.
3 These numerical flame spread and smoke developed ratings are not intended to reflect hazards presented by this material under actual fire conditions. All applicable building codes must be followed.
4 Not all combinations of thickness, length, width and edge profile are available.
