Does tanalised/kiln dried joist/carcassing timber need to a climate?

[Tirglas_7]

Hi,

Does it need to be left in an area its being installed to acclimate?

Can't find any reference online apart wood flooring, so I'm thinking no.

Probably a stupid question but thought I'd ask anyway:-/

Should not need to acclimatise , unless it’s been stored badly (damp etc).

Depends what you are using it for.

If you have the time its probably a good idea.

many timber / builders merchants keep their carcassing stock outside and it can be soaking wet when delivered.

if you are using it for walls that will be drylined, the movement can increase risk of plaster cracks etc.

Kiln dried doesn't because that is why is kiln dried.

Others do as there is risk of movement while it dries unless fully restrained.

Kiln dried timber that has been over dried may expand slightly if it can absorb moisture from a humid atmosphere.

But won't twist to buggery in the process

True.

If it's wet to the touch then leave it in 'Stick' until dry to touch. Then it should be OK to use, do use plenty of fixings though...

In 'Stick' - means a stack of timber with 3 or more sticks under and between every layer of timber so air can circulate around each timber. If it's likely to 'move' (warp or twist) then place heavy weights over a final layer of Dry timber lenghts.

just to further clarify
kiln dried simply means it was properly dried/seasoned via a heat source before converting to planks so would be fully relaxed so converted to planks with the wood fibres where they want to finish up
where as most timber is not properly seasoned so some to lots off movement can happen
