Exterior Application Guides


From stucco to stone to siding, InSoFast panels provide a simplified approach to wall assembly and detailing. InSoFast panels can be applied universally to any type of exterior wall in both new and retrofit construction projects without compilcated parts, peices, and extensive training. Providing unlimited finishing options.

InSoFast panels reduce the complication of building an exterior wall assembly with an all-in-one rainscreen and insulation solution

One Part Not So Many Pieces

The easiest way to install continuous insulation.
  • Simple to install
  • Less parts and pieces
  • Stud framing included attach any finish
  • Improves house wrap’s performance
  • Why work so hard?

  • Best Continuous Insulation

  • No energy penalty for the studs
  • Self-flashing panels
  • No taping seams
  • Non-conductive stud framing
  • Thermally recessed fasteners
  • Non corrosive stud...no rusting
  • Lives up to its name: In So Fast

  • Double Thermal Disconnect

    The panel provides a thermal and moisture disconnect from the exterior elements. Uninterrupted continuous insulation (CI) always improves a wall’s thermal performance. InSoFast goes beyond just “CI”. The fastener that attaches the panel is recessed into a ½” into the insulation reducing the fastener’s thermal shorts to near zero. Additionally, fastening the exterior cladding does not penetrate the weather resistant or thermal barrier keeping your building secure and dry. Use the EXe 2.5 panel where continuous insulation is required or just the responsible choice.


    Why work so hard? InSoFast takes the worry out of the complex wall assemblies. Insulation should be seamless, maintenance free, InSoFast panels are engineered with materials that will not rot, rust, warp, or decay when exposed to moisture. EPS foam is a stable material with zero thermal drift, maintaining its R-Value in extreme conditions, year after year.

    NFPA 285 Cladding Options

  • One detail, one solution
  • Continuous insulation for all assemblies
  • Improves and protects the continuous air barrier
  • Less parts and pieces = less training
  • Assemble Less. Build Better. Exceed Expectations

  • Complete Continuous Insulation

  • Built to last
  • Drains better, dries better, performs better
  • Redundancy, improved performance
  • Combines rainscreen, insulation, and attachment
  • No special tools and training
  • InSoFast just plain works better
  • Why Work So Hard?

  • Rain Screen Insulation

    InSoFast’s rain screen, “drain-and-dry” is accomplished with just two layers, the panel and the exterior finish material. The first primary layer of protection is the exterior siding that protects the outside from wind driven rain. The InSoFast panel adds a secondary layer of defense with the interlocking, self-aligning, self-flashing barrier between the siding, and the air and weather resistant barrier that secures the interior living space from the exterior elements. The built-in drainage plane controls and allows excess water to, “drain-and-dry”, keeping your building safe warm and dry.

    Suggested products for Exteriors Applications

    EXe 2.5


    Closed-cell, injection-molded EPS achieves R-10 insulation. Built into the front and back of the EX panel is a network of shingle-style capillary channels. The panels comply with Oregon Residential Speciality Code section R701.1 to serve as a certified rainscreen for exterior applications.

    InSoFast Plus Method

    Need a higher R-value? No Problem! Start with a base of InSoFast continuous insulation panels they are feature-rich and easy to install. Then add rigid foam insulation over top of InSoFast panels.
