I just received a sample of Tyvek Thermawrap external insulation in the mail

user-659915 | Posted in General Questions on

It’s being promoted as a vapor permeable alternative to foam board external insulation but I’m feeling dubious about how the installation is supposed to work. Anyone have any experience with this material?

    Here is a link to my January 2014 review of Tyvek ThermaWrap: Two New Exterior Insulation Products for Walls.

    You will probably also be interested in reading the comments on that page.

    Thanks Martin. Maybe DuPont can repurpose the product, market it to jewelry stores for lining gift boxes.
