They also take up a lot of space and the process of installation can be quite involved.
Strengthen roof trusses loft conversion.
New beams would be required.
Attic conversions are now possible by replacing the truss rafters with a shaped trusses or horizontal beams which in return create additional space.
For small loft conversions this can be done by installing additional wooden rafters but for large projects steel beams are usually required and these can be quite costly.
This process involves the installation and use of steel beams.
It typically costs around 4 000 for a set of 10 telebeam trusses sufficient for loft conversion of a small semi.
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.
Measure in from the lower edge of the roof to a point 1 4 the width of the truss on either side of the attic.
Use a chalk line to draw a line along the floor parallel to the lower edge of the roof from one end of the attic to the other on both sides.
This will often work out cheaper than using conventional steels once you factor in savings on labour access and plant hire etc.
Measure the width of your roof trusses from inside to inside.
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.
