Put a stop to cold feet

The solution to a tighter building envelope is right under your feet. Under insulated floors can lead to significant heat losses and reduce the livability of your space. Insulation, air-sealing, and adhesive products from DuPont Performance Building Solutions add energy efficiency and comfort to your building for years to come.


Floor Insulation

Reduce heat loss and avoid thermal bridges at the junction of the floors and walls by including a layer of thermal insulation in the floor construction that is continuous with that in the rest of the building envelope. DuPont™ Styrofoam™ Brand Extruded Polystyrene (XPS) Foam Insulation is a cost-effective solution for improving the thermal performance of residential and commercial floor applications. With its high-compressive strength and minimum deformation, Styrofoam™ Brand XPS offers durability and long-term energy efficiency.



Spray polyurethane foam adhesives are a must-have when it comes to floors, with applications in:

  • Subfloors, drywall, paneling, foam panels and most construction materials
  • Insulated concrete forms
  • Structural insulated panels

Air Sealing

When it comes to floors, eliminating air leaks is just as important as insulation. Spray polyurethane foam sealants are perfect for stopping drafts where the floor meets the base of the wall.
