Hi, thought I'd sign up and hop in on this helpful looking forum.
I've got a 5 year old garden cabin from Homebase. It's a pine, tongue and groove construction roughly an inch and a half thick. It's great in the Summer, quite damp and cold in the Winter. I use it as a workshop and general retreat at the bottom of the garden.
I want to retrofit the interior with insulation. A little digging around has led me to conclude that I'll be fitting an internal studwork wall using 2 by 2 baton, probably Polystyrene for insulation rather than Celotex and covering it with Gypsum plasterboard.
What I'm not sure about is membrane and air gaps. Do I staple a membrane to the existing (painted) wall first? Will I need to allow for an air gap between the Polystyrene and the existing wall? I'm just not sure.
I'd like to avoid doing anything that encourages rot/mould between the exiting building and the forthcoming insulated structure and It's important to try to keep the new walls to a reasonably minimum thickness so as to not lose too much internal space within the cabin.
Any helpful pointers would be really appreciated. Thanks
