For a number of years we have been using Tyvek® on trees in our Rock Springs orchards. Yes, the insulating material that new houses are wrapped in may help to reduce potential damage. We had been obtaining Tyvek® from a company in Canada but the quality of the product was inconsistent. In some years it came in a 3 ml thickness and in others it came in a 7 ml thickness. This past year we found a more consistent supplier.
The "guards" last about 3 to 5 years. This is long enough to overcome the concern about green bark. While we have not measured it we also believe we may be getting a benefit of the white reflecting sun during the summer and winter. To order go to www.uline.com and search for Tyvek products.
