About InSoFast

InSoFast is a style of engineered continuous insulation that comes in 2-foot x 4-foot interlocking panels of varying depths. The UX 2.0 Panel is 2-inches thick with a flat surface that exposes the face of the embedded studs. With a continuous R-value of 8.5, rot-resistant framing, drainage channels, electrical raceways, and a simple, stackable interlocking design, this panel is exceptionally cost-effective for base-level code requirements.

When you need a thicker panel with a higher R-value, the EX 2.5 Panel, at 2 ½-inches thick, is a great choice. 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. This InSoFast panel’s continuous R-value of 10 outperforms traditionally framed R-15 batt walls and provides 20% more insulation than our UX panels.

The InSoFast moisture control channels are designed to redirect the flow of potential moisture so that it does not become trapped in your walls and cause problems. However, InSoFast panels should not be considered a waterproofing solution. If your basement needs waterproofing, it must be done before InSoFast is installed.

Reasons Do-It-Yourselfers Love InSoFast

The features that make InSoFast panels so easy for do-it-yourselfers to use include:

  • Cut to fit with handsaw, jigsaw, sabre saw or table saw
  • Seamless interlocking edges require no taping
  • Easy to handle 2’x4’ panels stack like LEGO® bricks
  • Notched alignment system ensures that panels and studs stay aligned during installation
  • Built in embedded stud framing aligns every 16-inches on center to simplify gluing or screwing panels to walls
  • Built in electrical raceways run horizontally and vertically along the edge of every panel and enable you to install electrical boxes anywhere you need them
  • Moisture control channels prevent moisture from getting trapped in walls
  • Straight surface supports drywall and paneling as well as cabinets and TVs
