The Best Products And Quality in Building Supplies
Tyvek® ThermaWrap® R5.0, which is among a line of 17 Tyvek products, has an R-Value of 5.0, meaning it is combustion resistant. The product allows any water or moisture that finds itself inside the wall to escape to the outside, thereby leaving the wall completely dry and preventing mold and mildew formation. The product is indeed more breathable than its competitors like EPS, XPS, and Polyisocyanurate foam insulation.
The product comes in a roll with 6” uninsulated flaps at the start and bottom which allow for horizontal and vertical seam installation in a shingled manner. DuPont offers a 10-year limited warranty on Tyvek and its other weather barrier products.
