EnerSpan HD is manufactured using Neopor® provided by BASF, a graphite-enhanced raw material that reduces radiation heat transfer resulting in higher thermal resistance (R-value) compared to standard CAN/ULC-S701, Type 2 EPS insulation.

With an R-value of 4.7 per inch, EnerSpan HD helps you achieve your desired R-value with a thinner board. EnerSpan HD insulation is easy to work with and install, and consistently delivers the highest true R-value performance over time. This high-performing insulation is breathable, while the closed-cell structure does not support the growth of mold, while adapting to all climate zones. EnerSpan HD is a versatile insulation product that can be used in a wide range of applications.

EnerSpan HD EPS is a closed cell, rigid foam plastic insulation that maintains its R-value for the life of the product. When applied as continuous insulation over foundations, walls and roofs, EnerSpan HD insulation is a cost-effective solution that eliminates thermal bridging, increasing your total R-value. By increasing your energy efficiency with EnerSpan HD insulation, you will effectively reduce your heating and cooling costs.

Available in 2x8 ft. and 4x8 ft., 2 ft. high bundles

Thicknesses of ¾, 1, 1 ½, 2, 2 ½ , 3, 3 ½ , 4 inches, Plus special order sizes and thickness to meet job

  • Meets all building code requirements
  • Compressive Resistance of 16 psi
  • Thermal resistance of True R-value of 4.7 per inch
  • Closed cell insulation resists moisture
  • Easy to cut and install
  • Permanent R-value
  • Increases energy efficiency for reduced heating and cooling costs
  • Can be used for retrofit or new construction
  • Uses up to 30% less material than other rigid foam insulation to achieve the same R-value, saving on building materials and installation labor
  • Thinner boards are needed to reach the desired R-value than others so the same effect is achieved with less material
