Damage to Thermal Insulation Foams in Low-Slope Roof Systems Caused by Simulated Foot Traffic

Abstract

The results indicated that commonly used foam plastic roof msula tions will be damaged if exposed to foot traffic, and that their protection with fi brous overlay boards as recommended by roofing contractor associations [1,2] con tinues to be good roofing practice. The results also indicated that finished roof surfaces will be damaged if exposed to frequent roof traffic and that surface protec tion of the membrane is good roofing practice.
