Dupont Tyvek Thermawrap?

Question

I am looking at upgrading my house with Dupont Tyvek Thermawrap. The cost for this will be $2800. Does anyone have this installed in there house and does it really work? Will this save money on the long run for the electric bill.

Answer 1

Yes I do have it and yes it works. It keeps drafts to a minimum and breathes slowly. It has made a big difference in my house and the amount of heat I need.
