Attic Truss Loft Conversion

This may well require planning permission.

Attic truss loft conversion.

The conversion from a trussed roof to a trussless roof simply involves the redistribution of the roofs weight from the trusses to beams running from gable to gable. 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. 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.

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. Ironically though it s the rafters that provide a better environment for an attic conversion because of the clear space. Trussed rafters loft conversion most roofs built from the late 1960s onwards are of prefabricated trussed rafter construction with distinctive w shaped webbing. Attic conversions are now possible by replacing the truss rafters with a shaped trusses or horizontal beams which in return create additional space.

Trusses are considered a superior method of framing a roof because of the additional support. If you have trusses it will be next to impossible to reconfigure them to allow for clear space.
