Floor trusses with unsupported spans of up to 10 m could be used not only to form an ideal plain ceiling and floor surface, but to ensure perfect sound insulation (if filled in with proper sound insulating material).
They are used for floorings between storeys, balconies, verandas, and terrace roofs.
Preliminary calculation of a flooring girder price could be made using our on-line calculator for LGSF structures.
