Does MDF expand with the cold?

[dangerous]

Lined my new garage (studs 100cm apart) with 8mm MDF last week when it was stinking hot. Went out tonight and noticed some of the sheets are bowing out. Is this just down to the cold or am I going to have to take the bloody lot off and put in extra dwangs?

Arse.

as a Senior architectural building technician supervisor (chippy) the cuzzy board will be fine, the issue is with the lack of fixing.
Studs should be at a MAX spacing of 600mm and dwangs MAX spacing of 800mm for 9mm MDF
AND glue the MDF nailing it off at 150centers.
If your garage is damp and or insulated then sealing the mdf BOTH sides and all edges will be a good thing.

Marine grade ply not the standard stuff as it seperates with moisture

at over $200 a sheet... I dont think so.

"Dwangs". Nogs, you mean.

Rubbish. Construction ply is fine for lining a garage with. Marine ply is waaaay over the top, unless you have major water issues.

This is the south Island... its a dwang
correct re ply.
