Good day,
We have rented a semi-detached house. There is also a garden, garage, and crawl space available.
I would like to insulate the garage and cover it with OSB boards. The insulation should make the garage somewhat more comfortable in winter as well as in mid-summer; additionally, if possible, it should provide soundproofing to shield the surrounding neighborhood from my activities. Even though the landlord is very accommodating, I would prefer the low-cost option.
For this, I would lay XPS 20 (possibly 30mm) on the concrete floor and then place OSB boards on top. At the walls, I would leave a ventilation gap. Does this work, or is there a risk of trapped moisture? Another question is whether XPS dampens the sound of machines standing on it or transmits it without insulation. Is there maybe another alternative here (possibly Rockwool boards?) within a similar price range?
I would equip the walls (possibly only the one facing away from the house) with wooden battens (with soundproofing anchors), put the cheapest mineral wool in between, and then seal it with OSB. Is a vapor barrier needed here? Would XPS 20mm perhaps also be sufficient here? Soundproofing has the highest priority, so I think the thin insulation is sufficient.
We also have a crawl space 1.1m high that opens onto earth ground. The question here is whether it would be sensible to lay a tarp to block moisture from the ground. Is this feasible, or would a mold layer then form under the foil?
Thank you very much for any input; I am very curious whether I am on the right track or totally off base with my plan.
