Unfortunately the shed wasn't designed for internal cladding but I have been framing it up as strongly as possible. I had a question on the ceiling load and how much downward weight the C purlins can handle. These run the length of the shed and are spaced around 1500 apart and span almost 4 metres unsupported either side of the centre beam. I am running 5.7m lengths of 70 x 35 treated pine battens perpendicular to the C purlins at 400 centres and fixing them into the C purlins from underneath with baton screws. I think the weight of the timber is about 2kg a L/M and the 10mm gyprock 5.7kg/sqm. I may be wrong but my calculations put the total downward weight on the C purlins at about 9kg a square metre or 450 kg on the whole roof. Does this sound reasonable or could introduce structural issues for the roof? There will be some internal walls that will provide some support under the battens.
