Before work can begin a structural engineer will calculate the size of the steels required.
Attic truss loft conversion.
Often loft conversion projects can end up being a disappointment as on completion the owner finds out that roof height is very limited and as a result the space ends up being rather pokey.
Ironically though it s the rafters that provide a better environment for an attic conversion because of the clear space.
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.
This process involves the installation and use of steel beams.
Looking back i was very lucky in that my roof had an unusually high 47 degree pitch and so there was lots of head room.
Trusses are considered a superior method of framing a roof because of the additional support.
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.
If you have trusses it will be next to impossible to reconfigure them to allow for clear space.
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.
