How to Insulate Exterior Basement Walls

Install quickly and easily with a minimum of tools and supplies

If you are interested in a cost-effective, weather resistant, fast and easy to install insulation solution for exterior basement walls, discover how to insulate them with innovative closed-cell, injection-molded EPS foam insulation panels from InSoFast!

InSoFast, LLC, established in 2006, develops energy efficient building systems that exceed present and future energy codes, outperform the competition, and simplify the construction process. Our patented EPS insulation panels are manufactured and shipped to project sites across the country from our manufacturing facilities in Idaho, Massachusetts and Minnesota.

Our InSoFast EXe 2.5 Panel is an R-10 continuous insulation (CI) weather screen assembly that is optimized for exterior usage and maximizes energy efficiency and moisture management.

The 2 ½-inch thick panels feature dual-sided engineered drainage channels that allow multi-directional air flow and help ensure that no moisture penetrates the wall assembly.

How to Insulate Exterior Basement Walls

Panels can be installed over your existing weather resistant barrier or house wrap. They serve as a secondary weather resistant barrier that is well-suited to absorptive claddings such as stucco or stone and provide a much-needed capillary break from wood framed walls and sheathing.

Why Choose EPS Foam Panels?

EPS, or Expanded Polystyrene Foam, is the generic name for a lightweight rigid closed-cell foam that is manufactured by expanding polystyrene beads with steam and pressure to bond the beads together to form blocks or to shape molds. EPS is found in a multitude of applications, including InSoFast insulation panels.

EPS foam provides the following benefits:

  • non-porous, making it difficult for water vapor and air to pass through
  • approved for ground contact and below-grade applications
  • stronger, denser, and can carry heavier loads than open-cell foam
  • provides the highest R-value per dollar of the rigid foam insulation choices
  • continuous R-value of 10 (EXe 2.5 Panel) outperforms traditionally framed R-15 batt walls
  • R-value does not degrade over time
  • tightly interlocking panels create a resilient seal that will not change shape, dry or crack over time
  • eliminates the potential for mistaken thermal leaks and prevents water from reaching the face
  • meets or exceeds all required building and energy codes
  • panels can be easily cut and installed on the jobsite with a handsaw, utility knife, glue, and a caulk gun
