Conventional Trussed Roof System

Serpentine Roof

The system utilises pre-fabricated roof trusses, spandrel and gable panels and verge ladder frames. These come pre-designed, complete with all structural fixings and bracing requirements. Party wall spandrel panels can be pre-sheeted with limited combustible boards.

Where air tightness less than 3 is specified, we recommend the fitting of an air tightness membrane to the underside of the roof trusses, with a batten to the underside to accommodate services.

Where air tightness is greater than 3, the ceiling plasterboard can act as the air barrier, with appropriate sealing at edges and joints. Fitting of plasterboard should be similar to that required for the air membrane solution.
