Temperature Measurements in Fire Resistance Tests on Small-scale Gypsum Wallboard Assemblies with and without Resilient Channels

This report presents the temperature measurements from fire resistance tests conducted at the National Fire Laboratory on small-scale, non-insulated, gypsum wallboard protected assemblies with and without resilient channels. Assemblies with resilient channels include the installation of channels between the wood studs and the gypsum wallboard on the exposed side, on the unexposed side and on both the exposed and unexposed sides. Gypsum wallboard arrangements studied were 1 x 1 (one layer of board on both the exposed and unexposed sides) and 2 x 2 (two layers of board on both the exposed and unexposed sides). The average temperature distribution on the unexposed surface as well as on the inner-surfaces are presented.Ce rapport pr\ue9sente les mesures de la temp\ue9rature r\ue9alis\ue9es lors d?essais de r\ue9sistance au feu men\ue9s au Laboratoire national de l?incendie sur des ensembles \ue0 petite \ue9chelle prot\ue9g\ue9s par des plaques de pl\ue2tre non isol\ue9es, avec et sans profil\ue9s souples. Les ensembles avec profil\ue9s souples comprenaient l?installation de profil\ue9s entre les poteaux de bois et la plaque de pl\ue2tre du c\uf4t\ue9 expos\ue9, du c\uf4t\ue9 non expos\ue9, et des c\uf4t\ue9s expos\ue9 et non expos\ue9. Les arrangements de plaque de pl\ue2tre \ue9tudi\ue9s consistaient en une (1) \ue9paisseur de panneau sur le c\uf4t\ue9 expos\ue9 et sur le c\uf4t\ue9 non expos\ue9 (\uab 1 x 1 \ubb), et en deux (2) \ue9paisseurs de panneau sur le c\uf4t\ue9 expos\ue9 et sur le c\uf4t\ue9 non expos\ue9 (\uab 2 x 2 \ubb). On pr\ue9sente en outre la distribution des temp\ue9ratures moyennes sur la surface non expos\ue9e ainsi que sur les surfaces internes.Peer reviewed: NoNRC publication: Ye
