Best Insulation for Basement Exterior Walls

Upgrading the basement exterior walls with InSoFast insulation panels is the best method for stabilizing temps, minimizing moisture, and facilitating construction.

When InSoFast, LLC, began production in 2006, we targeted our panels to commercial construction needs. However, the panels meet and progress beyond energy regulations and make construction so simple that do-it-yourselfers have embraced the products as well.

Best Insulation for Basement Exterior Walls

By upgrading the exterior foundation of a home, homeowners provide protection for the physical composition of the wall and a process to keep water from draining toward the home. The panels that we create fit together into a continuous system of insulation that blocks moisture, vapor, air, and thermal energy loss.

A layer of InSoFast insulation panels helps protect, at the foundation, from thermal instability and moisture related issues. The panels reduce the likelihood of condensation, cold intrusion, and destruction of the waterproofing measures you’ve applied.

InSoFast Exterior Insulation Panels

  • Promote drainage of moisture;
  • Lessen the potential for interior condensation;
  • Protects waterproofing measures;
  • Offers lifelong thermal insulation.

From the sill plate to the crawl space, basement floor, basement interior, and the exterior, many unexpected spaces benefit from adding InSoFast insulation panels, an uncomplicated process that provides a lifetime of benefits.

Of all the rigid foam board materials, Expanded Polystyrene foam has the strongest R-value for the price, and InSoFast insulation panels are made of closed-cell EPS foam, with double the R-value as open-cell insulation tech.

InSoFast insulation panels do not break down as time passes – either physically or chemically. They can be used above and below ground level and can be modified to accommodate all flat surfaces, encapsulating the entire exterior or interior rooms.

The features of InSoFast insulation panels create a straightforward system of insulation that negates the need for tape, a team of workers, or specialized tools. The panels themselves can be installed with construction or masonry adhesive or nails or screws, and they can be modified with a utility knife or saw.

InSoFast Insulation Panels Designed for Exterior Applications

The Flat Panel EXe 2.5 produces R-10 continuous insulation, outperforming R-15 fiberglass insulation once the system is complete.

The panels are 2 ½” thick with drainage channels on each side to make sure that moisture doesn’t cross the insulation wall system. This system is a secondary weather resistant barrier and welcomes the application of multiple 2” finishing materials.

Finishing products can be screwed directly into the InSoFast exterior insulation panels’ embedded studs. Each of these polypropylene studs are as strong as 20-gauge steel studs, yet they’re non-conductive and a major part of the effectiveness of the continuous insulation system.

On older homes, renovations often include demo, abatement, and trim removal, but you don’t when you choose InSoFast insulation panels. A system created with our panels will fully encapsulate the home without any of these measures required.
