I've been reading some of the topics in this section with interest. I have a wooden garage on a concrete base. At the moment, the roof is timber with felt on it, but I have box profile sheets to put on when the snow is gone.

The wooden walls seem to get really wet on the inside in some places, almost like the rain is actually soaking through the wood (it's very old and thin but creosoted on the outside), which makes me wonder if I lined them with something like chipboard and filled the cavity with old papers or plastic bottles (i'm on a very tight budget here!), won't that all just get wet and rotten and cause more troubles?

The same applies to the inside of the roof which also gets a lot of condensation (currently frozen which looks rather nice!!) so if I lined that, surely the lining would just rot where the water is always dripping on it?

Your thoughts would be appreciated

What I mean to say, is, is the best form of insulation a cavity with perhaps a couple of vents from inside to outside? Sorry probably didn't make myself very clear in the first post!

do NOT use chipboard or mdf under any circumstances
sterling board or exteriour ply shuttering ply
you need to seperate the wet wood by a ventilation gap then a builders membrane then the insulation
