Effective insulation under concrete
EcoFoil Ultra CBF Under Slab Insulation surpasses conventional concrete floor insulation, such as polystyrene or foam sheets. Unlike these outdated alternatives, our reflective bubble concrete floor insulation not only prevents radiant heat loss or gain but also eliminates the need for an additional vapor barrier. Additionally, EcoFoil provides a protective barrier against radon and reflects 57% of radiant heat back to the concrete surface, ensuring optimal thermal performance for various applications, from driveways and radiant flooring to concrete slabs.
A radiant barrier and vapor barrier, all in one
Unlike traditional alternatives, Ultra CBF Under Slab Insulation doubles as a vapor barrier, eliminating the need for additional materials.

Eliminates formation of moisture and condensation on concrete
EcoFoil Ultra CBF Under Slab Insulation features of a layer of metalized foil centered between a layer of bubble insulation laminated to each side with a permanent bond. The bubble layers protect the reflective foil from exposure to the ground or the concrete, and provide a thermal break—eliminating buildup of condensation on the concrete. It is strong and durable enough to withstand the pressure and corrosive nature of concrete and provides the most heat reflectivity of any under slab insulation on the market.
What you'll need for installation:

More About EcoFoil Under Concrete Slab Insulation
Please Note: Standard Single or Double Bubble Foil Insulation is not recommended in a concrete insulation application. When foil comes into direct contact with the cement, especially while it is curing, the foil layer will corrode and destroy the reflective properties of the insulation. Ultra CBF Under Slab Insulation was developed and patented for this reason - to serve as a superior concrete floor insulation and concrete vapor barrier, but also to serve as a radiant barrier insulation which reflects radiant heat. This bubble insulation product also gives more reflectivity when used in a heated slab than any other concrete insulation product on the market. This will improve slab response times dramatically when used with radiant heat.
