I recently had a new sectional concrete garage built and painted the walls with masonary paint and the floor with epoxy paint.
With the very cold weather these last few weeks 1 of the walls is freezing and the side of the car facing that wall (approx 40" away) gets covered in condensation.
I'm thinking of fixing battons to the walls, foam insulation inbetween and wood boards on top so basically the inside of the garage is boarded out which i'm hoping will keep it warmer/ less damp inside.
I thought about plasterboard butthe paper bit could get damp? whould i be better using chipboard?

We had a cavity wall constructed in our very old house with plasterboard lined on one side with aluminium foil. The silver bit faces outwards.

That seems to have withstood any damp for a good number of years now.

Les - i was thinking wood would be more robust as well so if it got knocked, etc then instead of having the paper of the plasterboard torn the wood would just get scratched so not damaged?
I'm not sure which would be best - chipboard, MDF, plywood?

You could look into things like SIKA render, which is a waterproof render application (used in places like basements etc) although it may not prove cost effective against drylining the walls.

Marine Plywood from your last post, MDF & Chipboard do not perform well when wet....
