Hi all, I've been working on my flat roof construction and have plenty of 18mm T&G OSB3 sheets left. I was planning to use these for the first floor flooring in the house refurbishment, but have been told by a local building that I should use chipboard flooring instead. Any idea why this would be? thanks!

Hi All Am sure this topic has been covered before, but I would appreciate some advice/confirmation that I am on the right track. Am building a sloping flat roof garage: 1. 5.4m C16 225x75mm joists, each end to sit on inner half of flat laid block, with 400mm centres, running the width of the garage 2. To acquire 1:60 fall perpendicular to the joist, I am intending to screw fillets (rough sawn/75mm width) on top of each joist in declining heights to allow for fall to rear 3. Also x3 lengths of noggins to support joists 4. Cover joist/fillets with OSB3 - was thinking T&G to allow for fact no level noggins to help support. Hope this makes sense? Would welcome comments before I make a Charlie of myself! Thanks in advance. Best Dave

Slowly the specification for our roof is emerging from the mist that seems to swirl around at that level. It has been suggested ( in the words of the architect, ' ... or similar...') that we use 11 mm OSB3 and 6 mm cement board. That's easy I thought, look up what it costs on Tinternet and buy some. Well Stanley, here's Another Nice Mess (steep learning curve) I've Gotten Myself Into. Partly caused by the usefully ambiguous architect's phrase 'or similar' 2 hours in to digging around on YT, Google and other murky bits of the Internet I realise; OSB3 is water resistant - but what does that mean (it needs covering during boarding if it rains) OSB3 ' ...or similar...' could mean what? cement board can also be waterproof or water resistant : have you seen how many types of cement board there are! Which should I get? I have learned the hard way that architect's specify top-performance stuff. OK, fair enough. Could you help me specify something sensible in terms of 11mm OSB3 or something with the same performance, and suggest a sensible 6mm cement board, please? Yours, Semi - Irritated of Lancaster.
