Hipped roofs constructed with trussed rafters typically require a series of diminishing mono-pitched trusses supported by a girder truss. The bearing of mono-pitched trusses into shoes should be in accordance with Table 1, unless designed by an engineer in accordance with Technical Requirement R5.
Attic trusses: Allows for extra storage or living space within the roof. How do roof trusses work? Roof trusses act much like a lid on a box. They work by transferring the weight of the roof to the load bearing walls of the house. What are trusses made of? Our trusses are made from TR26.
How far can an attic truss span? The maximum span of a roof truss is determined by factors such as roof pitch and clear room size. As a rule of thumb spans in excess of 10m should be designed with an internal support.The size of roof trusses is normally limited by transport.
The ‘Room-in-Roof’ (‘RiR’) or attic trussed rafter is a simple means of providing the structural roof and floor in the same component. This offers considerable advantages over other forms of living roof construction: • There need be no restrictions on lower floor layouts since the trusses can clear span on to external walls although
