Osb vs plywood

[Molynoox]

8x2x18mm moisure resistant T&G chipboard aroumd £12 each, and thats not even shopping around. No brainer.

Great idea
I am a fan of this type of TGV chipboard flooring - the only small issue I can think of is the last board going in at a wall edge, you could possibly slide it in, but not if on the last row. Probably have to rip off the toungues on some sheets so you can get them in. Just something to think about but overall I like this idea.

I wonder if painted MDF would be an option?

Hi. Planning to insulate our new garage. We need to decide between OSB or plywood for the panels. Which to go for? The OSB is only slightly cheaper. I'm thinking the OSB will give a rather 'busy' look and be distracting in a workshop space, and be more difficult to paint if I later opt for lighter walls.

I used OSB on the apex roof as it is just woodcip and a lot of waterproof glue, and the cheapest 10mm ply I could find to line the interior. I also ran 100mm trunking around all the walls for ever-changing electrical needs without having to pull the sheets off..

I went with 11mm OSB for cost reasons. I’ve found it looks fine when painted, while it’s probably not as strong as ply, I’ve not had any issues hanging various things on the wall.

Thanks. Did you paint straight on to the OSB... What paint did you use please?

Yup, nothing fancy, cheapest emulsion I could get at B&Q. I did have a few issues of bits of the osb that contained lots of resin bleeding through the paint but for the purposes of a workshop, this didn’t bother me.

For the electrics I would suggest you use the most basic data trucking. That way you can position sockets and switches in the best location and add another with ease - leave plenty of slack in cable runs to allow additions to be made. The best thing that I’ve done in my new garage/workshop.

Do you get trade prices @Fergie 307? Local yard is quoting £10 more per sheet.

Bit like paper sizes having 'standards' eg A sizes, B iszes, C size (envelopes), US letter, US legal, Quatro and then Japan has its own 'standards'. Must be a tree thing.

Nope just googled it, first few prices were all between £12 - 14.

Even at the wickes rip off emporium its £18.50, so your yard is taking the Michael. Try any of the big sheet materials places, they deliver Nationwide. Google is your friend.

The one I can see for 12 is some click bait and actually a 4ft board.

If you can actually link to an 8ft board at 12 then feel free

Went to my local builders merchant today. The mixture of imperial and metric measurements is how they refer to them, and the building industry supposedly went metric 50 years ago.
All prices are plus VAT at 20%.

Bought some nominally 6x2 floor joists, actual dimensions 143x44mm. Grade C24, 4.8 metres long. £13.67 each.

I priced up the following
8x2 T&G chipboard flooring, 18mm, £14.86
8x4 hardwood ply, 12mm, £27.84 (18 months ago about £17)
8x4 OSB, 11mm, £15.75 (18 months ago about £17)
8x4 OSB, 18mm, £24.05

I asked them about the prices 18 months ago being the same for 11/12mm OSB and plywood and they agreed that the price differential had disappeared but had now come back.

EDIT
For those of you not in uk.
6x2 joist is cross section in inches.
8x2 flooring is nominally in feet but an effective length of 2.4 metres to suit 600 and 400 mm joist spacing. Effective width of 0.6m. Overall length and width is a bit more because of the tongue and grooves.
8x4 sheets are almost the actually dimensions in feet, they are 2440mm by 1220mm.

2440x1220x9mm

On checking the sheets were 11mm or 12mm thick.

Out of interest which merchant was that please? (I'm in Warwickshire and not seeing prices like that!)

It was Buildbase I have a cash account with them. Know them fairly well. For the plywood they initially said £31.96 then looked again.

I phoned up a few days ago for a price on the joists and and it was higher, closer to £20 plus vat, (actual price is in my other notebook which is not to hand). So I was pleasantly surprised, paid £82.02 for the five joists including vat, and they are fairly straight and smooth.

Do not buy a lot from them now but have been going there for years.

Direct Building Supplies is one £10.89 per sheet prob plus VAT and delivery.

Ah - I have a cash account too . . . the local branch in SuA stocks very little timber and is distinctly uninterested in getting anything they don't stock in . . . and they seem to run "casino pricing" that has no consistency from day to day. Locally Jewsons has more timber, and cutting, but expensive, TP is usually reasonable (and free delivery) with a good range.
