Fabric buildingsClearSpan Fabric Structures Hercules truss arch buildings feature high clearances and spacious interiors without support posts. They are outfitted with triple-galvanized structural steel frames that will hold up in corrosive environments. Rip-stop polyethylene covers let natural light shine through, eliminating the need for daytime artificial lighting and lowering energy costs. The buildings are custom-engineered to fit the requirements of the specific location, such as snow load or foundation type. They can be permanent or temporary, are easy to relocate, and can be built to any length and up to 300 feet wide. 866/643-1010; www.clearspan.com/adwso.Roof hatchThe Bilco Company’s enhanced-performance roof
