Specimens were aged and tested in accordance with FTC Rule (16 CFR, Part 460). The R-values shown for GreenGuard®-FP1450, GreenGuard®-XFP14, GreenGuard®-FP38, and GreenGuard®-XFP38 are system R-values calculated in accordance with the “ASHRAE Handbook of Fundamentals” using a ½” uniform, parallel dead air space. The R-values of these products installed without the benefit of a dead air space are 1.0 (GreenGuard®-FP1450 and GreenGuard®-XFP14) and 1.5 (GreenGuard®-XFP38).
2 These numerical flame spread and smoke ratings are not intended to reflect hazards presented by these materials under actual fire conditions (core data).
3 GreenGuard NP14 complies with all relevant building codes.
4 These dimensions apply to each fanfolded bundle.
