Can you convert an attic with trusses?

Attic conversions are now possible by replacing the truss rafters with A-shaped trusses or horizontal beams, which in return create additional space. Replacing the standard W-shaped trusses with steel beams across the length of the floor allows you to create a much larger and functional attic space for the house.

3. Brace gable ends with diagonal 2x4s.
4. Connect trusses to walls with hurricane tiedowns.

2. Measure the Old Joists.
3. Cut the Sister Joists.

5. Install Blocking.

How far should purlins be spaced?

When positioned, roof purlins should be spaced no further than 1.2 metres apart when using sheeting with a thickness of 0.7mm, and 1 metre when using 0.5mm sheeting. Exact requirements will vary, but as a rough guide, this is a good rule of thumb to follow.

Are purlins load bearing?

In architecture or structural engineering or building, a purlin (or purline) is a horizontal structural member in a roof. Purlins support the loads from the roof deck or sheathing and are supported by the principal rafters and/or the building walls, steel beams etc.

What to look for in a loft roof?

Internal roof elements to consider during loft conversions consist of a number of sub-structures such as ridge boards, rafters, purlins, joists, wall plates and steel beams. In the roof space, as the name suggests, the ridge board is the length of timber which runs horizontally along the apex of the roof.

Where do the beams go in a loft roof?

Beams in loft conversions travel horizontally below the ridge board and between the two end gables of the conversion. There is some degree of choice in exactly where the beam is located in the apex of the roof though the difference is minimal, although there is sometimes the option to offset the beam directly below the slope of the roof.

What are the rafters used for in a loft roof?

Fixed from the ridge board to the wallplates the role of the rafters is to support the material covering the roof. Other rafters used in the loft roof structures are: Jack rafters – the two short ‘v’ shaped rafters which run from the ridge board to the valley rafter.
