Development of energy ratings for insulated wall assemblies

This paper is one in a series to present information generated from a research project conducted jointly by the National Research Council Institute for Research in Construction (NRC-IRC) and the polyurethane industry (contractors, and material suppliers) to assess the overall performance of insulated walls. In an earlier paper [3], the authors presented a brief outline of the project objectives and a limited set of results of two walls that were available at that time. A second paper presented at an ASTM Symposium [4], where the test results of six walls were presented. These walls included glass fiber poly-sealed (two reference walls) as well as four walls of medium density foam (closed cell foam) insulation.Ce document fait partie d?une s\ue9rie visant \ue0 pr\ue9senter de l?information issue d?un projet de recherche r\ue9alis\ue9 conjointement par l?Institut de recherche en construction du Conseil national de recherches du Canada (IRC-CNRC) et par l?industrie des polyur\ue9thanes (entrepreneurs et fournisseurs de mat\ue9riaux) dans le but d?\ue9valuer la performance globale de murs isol\ue9s. Dans le cadre d?un document ant\ue9rieur, les auteurs ont pr\ue9sent\ue9 un bref aper\ue7u des objectifs du projet ainsi qu?un ensemble limit\ue9 de r\ue9sultats obtenus avec deux (2) murs qui \ue9taient disponibles \ue0 ce moment. Un second document a \ue9t\ue9 pr\ue9sent\ue9 lors d?un symposium de l?ASTM, o\uf9 les r\ue9sultats d?essais men\ue9s sur six (6) murs ont \ue9t\ue9 expos\ue9s. Ceux-ci comprenaient des murs en fibre de verre \ue0 scellement en polyur\ue9thane, soit deux (2) murs de contr\uf4le, ainsi que les quatre (4) murs isol\ue9s en mousse de densit\ue9 moyenne (mousse plastique \ue0 alv\ue9oles ferm\ue9s).Peer reviewed: YesNRC publication: Ye
