Thermal Moisture Barrier

What is Tuff-Stuff ?

Tuff-Stuff provides an absolute moisture barrier and effective insulation under concrete slabs. This insulation is made up of two layers of high-strength polyethylene bubble film, giving it superior puncture-resistance; it's tough enough to walk on. Tuff-Stuff is not only easy to install, it also offers labor and material savings because it is an all-in-one radon vapor barrier and insulation product. Perfect for resisting moisture and minimizing heat loss through slabs.

Why Use It?

• Reduces downward heat flow by more than 50 percent
• Superior tear and puncture resistance with >500 PSI
• Lightweight and pliable; easy and safe to install
• Excellent moisture barrier under concrete
• Enhances performance of entire insulation system
• Acts as a radon gas barrier
