Roberts Moisture Barrier Polyethylene Film for Flooring Protection

The Roberts Moisture Barrier Polyethylene Film is a dependable, cost-effective solution designed to protect flooring installations from damaging subfloor moisture. Made from durable polyethylene, this film helps safeguard your investment by creating a critical moisture barrier beneath floating floors.

Reliable Moisture Protection Where It Matters

This polyethylene film is installed directly over concrete or other moisture-prone subfloors before laying laminate, engineered hardwood, or certain vinyl flooring. Its primary role is to block moisture vapor from migrating upward, helping prevent warping, cupping, or adhesive failure over time.

Built for Consistent Performance

Engineered for long-lasting reliability, the film resists punctures during installation and maintains a consistent barrier across the entire floor. When seams are properly overlapped and taped, it delivers dependable vapor protection that meets common flooring manufacturer requirements.

Simple, Installer-Friendly Application

Lightweight and easy to roll out, this moisture barrier film cuts cleanly and lays flat for fast coverage. It’s a straightforward solution for both DIY homeowners and professional installers looking for efficiency without compromising performance.
