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.
Claims14
A metal building insulation system, comprising:
- elongate metal structural members of a building frame spaced apart from one another in mutually parallel relationship;
- said structural members each having a flange at the outermost sides of the respective structural member;
- said flanges each having an outer face directed outwardly of said building frame;
- at least one layer of heat insulating material extending between said structural members;
- and
- means for retaining said heat insulating layer relative to said structural member, said retaining means comprising:
- (a) a channel member overlying said flanges of each of said structural members and having an intermediate portion located outwardly of and extending across respective ones of said outer faces, a pair of side walls projecting inwardly from opposite longitudinal sides of said intermediate portion and a retainer projection extending laterally of the respective structural member from one of said side walls and located inwardly of said heat insulating layer;
- and
- (b) an additional flange facing inwardly of the building frame from the innermost sides of each of said structural members, said additional flange projecting laterally of the respective structural member at the side thereof opposite from the respective retainer projection, whereby said heat insulating layer is retained by said additional flange and by said retainer projection at the opposite sides of said structural member.
