Lining a shed - installing insulation batts

[Robbiep]

Hi guys,

I am going to be starting with me my shed to "teenagers retreat" conversion this weekend. I have decided to go with 7mm plywood attached to the existing frame as the internal lining.

The first step will be the selection of insulation batts and I?m likely to go with Earthwool. Depening on the thickness of the internal wall (I think 80-90mm), I am likely to go with a R ? 2.7 rating product.

The question I have is do I need add some sort of moisture barrier between the metal shed wall and the installation batts?

I live in South Australia, so humidity isn?t a big concern, but I am happy to put something up ?just in case?

Any thoughts?

Regards,
Robbie

Only a opinion,but you may not need too if you install this gear,and frame up the wall sections..imho..

Thanks!

Earthwool do offer a foil backed "space blanket", but it probably costs about 25% more in price, but reduces your R rating from 2 too 1.8. Not sure if that would affect things too much in terms of insulation.
