AbstractThermal insulation in protected membrane roofing may be exposed to rain and snow. Outdoor experiments with roofing insulations, including some polystyrenes, polyurethanes, wood fibre, glass fibre and perlite-fibre, confirm the severity of the problem of moisture attack but indicate that protecting insulations by surface sealing and providing for moisture escape by evaporation and drainage may keep moisture contents of even some porous insulations at low levels.
