We probably could have gotten by with one 164′ roll, and one 65.5′ roll. It would have been VERY tight with no room for any errors, so I probably would still order two 164′ rolls again. . .
We used ten rolls of the 2 3/8″ tape before insulating and could have used more. We have ordered one roll of the 6″ wide tape for patching the blown in insulation holes, and four more rolls of the 2 3/8″ tape to finish taping where needed.
We dealt with Doug at Red Rock Insulation to get quotes for insulating our tiny house with high density cellulose. He was responsive and fair. We had a great experience and would recommend them to others in the Vegas area. Tell them Jeff & Megan at Room to Spare Tiny House sent you!
