Excellent Moisture Barrier Under Concrete

Tuff-Stuff is an absolute moisture barrier and high-strength insulation under concrete slabs. This insulation was designed with two layers of high-strength polyethylene bubble film, giving it superior puncture-resistance; it's tough enough to walk on and can reduce downward heat flow by more than 50 percent. Tuff-Stuff is not only easy to install, but it can also save you money on labor and materials; because it is an all-in-one radon vapor barrier and insulation product. TUFF STUFF is perfect for resisting moisture and minimizing heat loss through concrete slabs and will enhance the performance of your entire insulation system.
