In reply to trim or walls first by terri roberts on March 2nd, 2003 10:43 AM [Go to top of thread]

I've been thinking of insulating the outside of my house. I have 2X4 walls and need more insulation for the increase in gas cost. I heard that donacona board has a R value of 16 but Nelson lumber says it has no R value. Could you tell me if you ever seen the donacona board. Also what do you suggest on isulation for my house.
