Gargage walls

[robby71]

We had a new sectional garage built a couple of years ago with a pitched roof. Last winter when it was really cold the contents were covered in condensation and the walls were really cold.
Before this winter i was wanting to put something against the walls to stop the cold comming through but don't want to lose width in the garage so don't want several layers.
I was thinking of fixing batons to the walls then putting chipboard flooring but have read this absorbs moisture? would MDF be better?
I could slot some insulation panels behind the boards in the wall recesses?

Thanks

Hi Robby71,
Whatever you do, don't use MDF to line the walls. It will absorb the moisture like a sponge. Not sure what the best thing would be to use, I'm sure other members will be along shortly to advise.

You will have to lose a little bit of the width to do it properly.

Battons on the wall.

Insulation inbetween the battons which is foil coated and tape the seams. This will act as your vapour barrier.

Then plasterboard on the battons

It's also been suggested to myself in the past to have an additional continuous layer of insulation across the timbers or insulated plasterboard. This is to stop there being any chance of getting pattern staining on the plaster or decorations in line with the timber battens. It's to do with the timber being on a cold wall.

Also is there enough insulation in the roof?
