The room-in-the-roof zone can be formed by an array of structures, including, attic trusses, pitched roof easi-joist® and a joist floor system or something as crude as steels and traditional cut timbers.
Merronbrook’s product combination
With Merronbrook’s trussed rafters and joist combination, we can construct an attic type truss, which incorporates timber rafters, posts and collars, but utilises our easi-joist® to form the bottom chord member. This gives increased truss spans and will create a larger room-in-the-roof space. This type of truss can be formed into an apex or flat-topped truss, depending on spans, pitch and height.
