How to Insulate 44m2 Concrete Slab Garage: Wool vs 5cm Foam, OSB Installation & Best Practices

Question

Colleagues, as in the subject I have a garage of concrete slabs about 44m2 unheated wants to insulate it from the inside with wool between the columns and press OSB and I do not know if this is a good idea? Maybe push 5cm foam instead of wool, I don't know, I will suggest something

Better steropian. The cotton wool will catch moisture, and from all this I think that the best foam would be sprayed. But this is only my summary

chudy0321 · Answer

no, but it is not known what the cost of such an operation and later wants to cover it from the inside OSB, you will have to equal the foam: /

barton21 · Answer

So only steropian remains. The foam comes out about PLN 55 per m2 with 20cm insulation thickness

and what about insulation from the inside will be ok or not insulating from the inside /?

Warming up the unheated room I would wonder if the skin is worth the trip.

In general, I think that you can insulate from the inside. Only with steropian or foam. What you insulate depends on your wallet capacity really. You just have to calculate the costs and see what you get cheaper.

And how will you insulate the roof? And how is he made? 44m2 is not a small garage ...

chudy0321 · Answer

I have a membrane on the roof and the ceiling made of wooden boards is warmer like at the bottom

Anonymous · Answer

Generally, warming should be done on the colder side. In the case of a free-standing garage heated sporadically I do not know if OSB alone would not be enough if you will only occasionally heat the goat there. With short sleeves you won't work anyway and for garage works 14-16 degrees C. it is how it was found and you will achieve such temperature without problems if you have a loft, that is, I understand that there are loft floor boards on the ceiling of the garage. It could only be somehow (also OSB) to raise boards on the ceiling of the garage.
