Finish your basement with fewer steps, less time, and less labor by installing cost-effective interlocking continuous insulation panels from InSoFast. Install drywall, cement board, tile base, or wood siding over the panels just like over traditional framing and transform the basement into an attractive, energy efficient, usable space.

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.

Avoid Basement Insulation Mistakes

Most homeowners today want dry, comfortable, livable basements. The basement is often a major source of energy loss. Moisture management is also important because basements are notorious for water intrusion, humidity and mold problems.

The least expensive and most effective way to address these issues is with insulation, which is designed to keep conditioned air in and the elements out. It can be done by handy do-it-yourselfers, but it’s important to choose the right type of insulation.

Fiberglass, a popular choice, is not moisture-resistant and is a terrible way to remodel a basement. It is a recipe for mold, rot and poor indoor air quality that can create potentially unhealthy conditions. Over-insulation can also lead to mold problems. Since insulation decreases the flow of energy, it decreases the energy needed for moisture to evaporate.

An excellent, cost-effective way to insulate your basement interior is with closed-cell, injection-molded EPS foam panels from InSoFast!

Feature-Rich InSoFast Panels

InSoFast is a style of engineered continuous insulation that comes in 2-foot x 4-foot interlocking panels of varying thicknesses. The closed-cell, injection-molded EPS foam panels can be applied universally to any interior or exterior wall assembly in both new and retrofit construction projects. 

The InSoFast UX 2.0 Panel is 2-inches thick with a flat surface that exposes the face of the embedded studs. R-8.5 continuous insulation, rot-resistant framing, drainage channels, electrical raceways, and a simple, stackable interlocking design make this panel the most cost-effective solution for base-level code requirements.

The InSoFast EXi 2.5 Panel is 2 ½-inches thick. If you need a solution that goes beyond base-level, this panel’s continuous R-value of 10 outperforms traditionally framed R-15 batt walls and provides 20% more insulation than our UX panels. Its tighter interlocks and recessed studs keep the EX barrier truer and straighter, enabling it to bridge over cups, bows and other irregularities in concrete basement walls.

Panels include built-in chases that run both vertically and horizontally across each panel, enabling you to install electrical boxes anywhere you need them. They also provide a simple, easy way to insulate cold concrete floors. The attachment studs provide a secure surface to screw the subfloor.

InSoFast insulation panels are the perfect way to insulate your cold, damp basement. Call us today at (888) 501-7899 or contact us online to learn more about our products. We offer free shipping and our panels are designed for do-it-yourself simplicity.
