Does anyone know what R-factor is required for a private rehab?
We have 2 x 6 rafters and need to insulate, but no where can we find answers to our questions and no one has responded at BSEED to our requests. We can only insulate to R-23 (if we are lucky...need to leave venting space) Anyone recently put in insulation?
