Trussed rafter roofs, also known as roof trusses, provide a structural framework to support the roof fabric, ceilings or floors of buildings in both domestic and commercial structures.
There are many different types of roof trusses. Robust and reliable, they can be used on a wide range of building types including timber frame, masonry and steel frame.
- Suitable for a wide range of roof structures and building types
- Speed of construction allows just-in-time delivery to site
- Space saving – no on-site storage area required
- Prefabricated components mean reduced labour costs
- More thermally efficient than alternative materials such as aluminium, steel or concrete
- Made of timber, the only truly renewable building resource
- Low-tech manufacturing process reduces emissions and pollution
- Minimal environmental impact from installation
Trussed rafter roofs are individually designed components made from kiln-dried, strength-graded timber joined together with durable steel nail plates.
They are a highly-engineered product manufactured in factory-controlled conditions to high production standards.
Roof trusses lend themselves to framing both simple and complex roofscapes in unparalleled timescales. Roof features can be constructed on ground level and then craned into position, or constructed at roof level if preferred.
Trussed rafters for selfbuild and new homes
TRA members provide bespoke designs for all types of home builders, from major volume housebuilders to individual self and custom builders and community selfbuild projects.
Many members can also help with supply and fit, or supply, fit and finish services according to your needs and budget.
Trussed rafters for industrial and commercial roofs
Trussed rafter sizes for commercial application go beyond the standard domestic 35mm and 45mm TR26 timbers to allow for much greater spans. With roof trusses, large spans and challenging roof contours are no barrier to creating innovative, eye-catching design solutions.
Many TRA members specialise in the delivery of commercial trussed rafters, supplying roofs for hospitals, supermarkets, schools and many other large public spaces, and designed to the Eurocode 5 design code for best practice structural integrity.
