Log cabin with housewrap (air barrier)?
I am based in South Poland where we have Summers +30c and Winters -30c, I am in the process of building a log cabin from reclaimed beams.
My wall design will be as follows…
1. External logs (20cm thick) with chinking and Mineral Wool in joints to seal gaps
2. House Wrap
3. Mineral Wool 20cm
4. Vapour Barrier
5. Final wall finish
My concern is with layer 2, the House Wrap. I wish to make the property as air-tight as possible but worried moisture may get stuck between the External Logs and House Wrap, resulting in the logs rotting.
Maybe I should reverse the House Wrap to allow moisture from layer 2 to 3 and let the Mineral Wool deal with it? (just an idea, maybe crazy). Or do away with the House Wrap and allow the logs to breathe in both directions, but worried I then lose the opportunity to have airtight insulation.
Keen to hear others thoughts regarding this, there is very little regarding this on the web for Log Cabins.
