Glass wool in a house that cools and warms up alternating. Should I replace it?

I have a small house in the woods that I currently renovating. At the moment, and for some years ahead, I will mostly use it every other week. I have no means to keep it warm when I´m not there. About half is a newer build and is insulated with glass wool. I think 145 mm in floors, walls and ceiling. No vapor barrier. I´ve read that one shouldn´t use mineral insulation in a house the warms and cools down like this. So the question is; should I replace existing insulation with wood fibre insulation instead, to avoid potential damage in the future? Are there more than anecdotal reasons to? I´m going to insulate the rest of the house with wood fibre. submitted by /u/TheFladderMus [link] [comments]
