Stirling Board Loft floor

[Guest cosmic dave]

Does anyone know any good reason why not to use stirling board as flooring in the loft, It would be well sealed with acrylic varnish, and would have no joins.

[Guest]

personally i would not use it for a floor

even sealed it will scrape off when you scrape the floor

if water/damp gets into it its knackered

i always use marine plywood

 

my loft roof is stirling board and has sprung a leak

very difficult to try and dry out so looks like i will have to replace it with ply

Yes the glue gives off toxic fumes when pigeons crap on it, it also flakes when you scrape it, if you are going to use it cover it with a thin (6mm) ply that you can replace if need be. Personally I would use 18mm water resistant tongue and groove chipboard

Thanks dave I'm trying to save a few quid, looks like I may have to invest in some ply aswell  

Thanks dovescot thats not a bad idea

[Guest shadow]

it splinters when scraped

My y/b loft floor is 1 inch thick chipboard that i got for nowt oot the work but i covered it with 6mm exterior ply (aboot £7 a sheet) and it's no problem to scape

Definitely not sterling board for floor Dave. I know it's less expensive than ply & chipboard, but it's a nightmare to scrape. Not a problem on roof, providing you use enough joists to stop it bowing. Remember, if you have a roof problem, not a big deal to fix or even replace, but you can't do that with a floor. I always use 3/4" or 1" chipboard for floor, the only thing I do is when I have the floor built, is to give it 3 coats of creosote before laying it down. OMO.

You get different grades of sterling board, it also has two sides one is plain and the other is sealed which has to laid upwards to resist moisture, I would use any less than 25mm on a roof. 18mm is for 400mm max width between supports and 25mm is for 600mm max width between supports. my lofts are 400mm between joists

Best to use wood that is able to breath = less condensation = less moulds.

go to a local builders merchant and get 18mm shuttering ply, 8x4 about £15 a sheet.

DIY stores usualy at least double the price.

the stuff ive got came with the blakes loft duncan

prob the cheapest of quality

ive used the tounge & groove chipboard its good scrapes easy and u dont notice the joins gonna do the rest of my loft with it but maybe the water resistant chipboard flooring will stop moisture getting into the floor

forgot to add works out about £12 quid per 8ft X4 ft of flooring so cheap as well

Yes my lofts all floored with treated t&g chipboard top layer compressed and hard which makes it easy scraped, dont use sterling board,very difficult to scrape and wont be much cheaper than chipboard flooring.

[gulkie]

big mistake to use sterling board ,dove cots right 8x2 treated

chipboard 3/4. if u use sterling board u will need 12"centres

in ur joist for 3/4 board. good luck.
