Replacing floorboards

[bscousegit]

I am in the middle of trying to replace old floorboards ( already removed and thrown out ) for a 2.4 x 1.4 m area.
The old floorboards are tongue and groove 4 and 1/2 inches width and 1/2 inch depth.
Unfortunately without thinking ( a floorboard is a floorboard isn't it? ) I have bought new floorboards that depth is 11/16ths.
Idealy I would like to find the right depth and width of replacement floorboard, but failing that are there any alternatives?

Trying to make the floor good so that vinyl can be laid on both concrete area and floorboard area without seeing the join ( chap who is putting vinyl down will put thin hardboard over floorboards and screed the concrete )

I have been there before

I once ripped up some floor boards that where badly eaten with woodworm, went to builders merchants got some new ones, returned home and they were a couple of mill thinner ?

I replaced the whole floor with flooring grade chipboard as it was a large area that needed replacing.

Can't you get some timber cut to make up the difference between the new and old boards?

If you get strips the same width or similar you can glue it to the joist and then just lay the boards on top as normal?

You might have to remove the tongue, where the new meets old though!

Perhaps one of the chippies will have a better idea, or know where to get the correct thickness boards?

I was going to suggest have a look in your loft,( normaly a few planks or so ) but then I looked at the sq m involved Have you checked out water proof ply at your local center?

boards from the sheds [b&q hombase ect ]are 18mm that goes for all 1" planed or machined timber
whereas timber from wood yards comes out around 20mm [3/4"]

so if your replacing old timber go to your local timber yard
may cost a bit more but the wood is better quality and they often deliver free

they will also usualy free convert larger sizes into what you want

but to be honest if your flooring is 12mm thick i would look at adjusting up the thickness as 12 mm is way to thin

i appologise if i have misunderstood

yes thats right 12.7 = 1/2

but i have never heard of half inch floor boards except as a bodge
so assuming a slight error

Thanks for your replies
Ended up going to the dreaded B&Q
I was suprised as the sell 16 mm floorboards and were very helpful.
They said that unlikely that the old floorboards were 12 mm and advised 16 mm should do.
Hope the guy who fits the hardboard on top can get different thickness hardboard to allow for the slightly raised new boards.
