200 sqft, 4ft x 50ft Under-Slab Concrete Radiant Heat Reflective Bubble Insulation, Underpad

Brand: Flexeal
Part#: FX-PDBF-48-50
48" wide x 50ft long (200 sqft total) multi-layer Foil/Double Bubble/Poly for under-slab concrete applications.
This insulation is designed for installation below the concrete pad to provide a basic thermal break (R-1.1 value), vapor & radon barrier and a decoupling membrane.
This insulation is resistant to mold, fungi and insects and is sufficiently durable to withstand punctures, tears and light foor traffic.
Best suited for projects where traditional (such as EPS foam) slab insulation is optional and or unfeasible. When multiple rolls are installed, we suggest using a 3" poly tape (polyester tape w/ acrylic adhesive backing) to seal the seams - be sure the top layer is clean to ensure poper adhesion. As with other sheet building materials, the best practice is to stagger the joints/seams.
Note:Clear poly layer must be facing up.
