15mm or 5/8" floorboards?

[dobbslc]

I need some 15mm or 5/8" floorboards to match the level of an exising floor but can't find any localy. Anybody know of a place that does them? Ply would do but seems bladdy expensive!

18mm is the norm

Cant you just shim/pack on top of the joists and use 12mm boards?

 

[123hotchef]

or use 12mm boards then overlay with 3mm ply or hard board

Pop in a sawmill. Get them made to size if your just patching a few.
If a whole room a few mm in the threshold won't hurt

as post 4 just pack the joists with either thin ply or hardboard strips

12mm boards a bit iffy.
Worst case buy 15mm ply and cut boards from that.http://www.builderdepot.co.uk/15mm-x-1220mm-x-2440mm-wbp-bb-cc-external-plywood.html

yes depending on widths between joists

You could always glue 3mm ply cut to the board sizes to the bottom side, Should stiffen them up nicely.

18mm 400c 22mm 600c

400 centres as I had to fit them between the existing ceiling joists. It's an alcove for a deck so 15mm ply will be fine or some 12mm and 3mm screwed on top.
