Cost effective way to get 2 hour fire rating in automotive garage
For zoning reasons I need to have a 2 hour fire rating on every surface of a 1250 sqft room which I will be using for an automotive garage and it needs to be installed on only one side of the surface, I can't change what is on the other side of the wall



Type c drywall seems like one way to meet this requirement but it's not really a great look to drywall an entire garage. I was wondering, are there any other products, maybe things that look less finished or aren't finish materials at all but which I could use to achieve this fire rating in a cost effective manner?
