Abstract
A metal building insulation system facilitates the installation of insulation in the roof and walls of a building from the exterior of the building and employs channel members fitted over outwardly facing flanges on the structural members from the exterior of the building, the channel members having opposed side walls for receiving the structural members therebetween and intermediate walls connecting the side walls. At least one layer of insulating material is retained between successive structural members by means of projections extending outwardly from the side walls of the channel members and inwardly facing flanges on the structural members.
