Loft Conversion

Loft to be used for storage. 2200mm span between middle joists

Anonymous user 28/02/2024 - 4.07 PM

There is a 2200mm span between the roof trusses in the middle of the space, where the loft access door is. The overall length (90 degrees to the roof trusses) is 6-7m long with a 2.2m central gap that Im looking to span over. The spacing of the trusses either side of the 2.2m gap is at 600mm centers What size timbers should I need to use to reach over the span? This would only be for general storage, and also hold a persons weight. Thanks

Are you a tradesperson and able to answer this question?

Hi Josh, Most common type of joist use for flooring is 150mm x 47mm. You cannot go wrong with this size, the details you have provided aren't totally clear but hope this helps. Regards John

150mm x47mm would be standard on a job like that

Hi is it 2200mm overall or from the centre to either side ? I would recommend a 145mm x 45mmC16 joist levelled and nailed to your existing joists Cheers GST joiners
