Abstract
A subpurlin (10) is provided for a building assembly having a plurality of overhead structural members (50), an insulating layer (62) and a plurality of overlapping roof panels (56). The subpurlins (10) support and space the roof panels (56) without compressing the insulating layer (62). Connector assemblies (30) secure the subpurlins (10) on the structural members (50) while permitting differential thermal movements between the roof panels (56) and the structural members (50). The connector assemblies (30) have ferrules (32) which slidingly engage slots (16) in the subpurlins (10). Washers (34) are fastened to the structural members (50) through the ferrules (32) during subpurlin (10) installation.
