Can I install vinyl siding over mineral wool without furring strips
I am siding my house and have purchased exterior 2 inch thick rockwool in 8 pound compression rating. I would like to install vinyl siding over this. Is this ok without furring strips? I purchased the rockwool before I realized I may need furring strips. Adding them would add alot of cost and time I don’t have. I was going to buck windows out with lumber and was considering bucking out all outside corners with lumber as I know this is probably where the rockwool is the weakest. Has anyone put vinyl siding over rockwool without furring strips? I’m really hoping this is a possibility. I will be using hurricane washers to attach the rockwool. I would appreciate any advice anyone has. Also I’m just a homeowner trying to do this myself as I could not find a contractor to take on any work as they are all to busy.
