Attic Truss Loft Conversion

Often the height of the roof may be too low when constructed with truss rafters which means that it may need to be raised too.

Attic truss loft conversion.

Ironically though it s the rafters that provide a better environment for an attic conversion because of the clear space. If you have trusses it will be next to impossible to reconfigure them to allow for clear space. The role of the horizontal beam is to tie the truss together and carry the load that would otherwise be sustained by the support and vertical timber also known as the king post. This process involves the installation and use of steel beams.

Trussed rafters loft conversion most roofs built from the late 1960s onwards are of prefabricated trussed rafter construction with distinctive w shaped webbing. This may well require planning permission. A truss frame will occupy the majority of the space within the loft which means that the whole structure needs replacing if you decide to convert your attic. Before work can begin a structural engineer will calculate the size of the steels required.

Trusses are considered a superior method of framing a roof because of the additional support. Attic conversions are now possible by replacing the truss rafters with a shaped trusses or horizontal beams which in return create additional space.
