ᐅ Attic Conversion – Use OSB or Drywall?

Since we are already on the topic, related to the other discussion Attic Storage Expansion

We are still undecided whether to use OSB boards or drywall (plasterboard) directly for the renovation. Unfortunately, even after talking to various friends and acquaintances, we haven’t become much wiser 🙁

Can anyone share some insights on the pros and cons....?

Thanks a lot in advance 🙂
