Exterior Wall Insulation

Install over your existing weather resistant barrier or house wrap

Before choosing exterior wall insulation for your new or retrofit construction project, consider the advantages of InSoFast interlocking continuous insulation panels that are easy to install, weather resistant, cost-effective, and capable of supporting fiber-cement siding or even stone veneer.

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

Exterior Wall Insulation

The Perfect Insulation for Residential Exteriors

InSoFast is a style of engineered continuous insulation that comes in 2-foot x 4-foot interlocking panels of varying depths. The closed-cell, injection-molded EPS foam panels provide a layer of continuous insulation over framing members or framed walls and eliminate the thermal bridging through un-insulated studs of existing framing.

InSoFast 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.

The InSoFast EX 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.

Siding can be attached directly to the panel’s embedded stud framing. The polypropylene plastic studs have the same structural strength of 20-gauge steel studs but, unlike metal, do not conduct heat and will not disrupt the home’s thermal protection.

Exterior finishing options include thin brick, metal panels, tile, cultured stone, stucco, and cement board siding, to name a few. The panels are rated for up to 2” thick adhered stone or brick. All finishes mount to the same CI-System so that one building can have several different looks without disrupting the rainscreen or the primary building envelope.

With tightly interlocking tongue-and-groove edges that don’t require taping, the installation of InSoFast EX 2.5 Panels could not be any easier and requires only a utility knife, saw (hand, jig, skill or table), screw gun or optional nail gun, and gap and crack foam to seal corners/openings and at the top of the wall.

If you are planning to retrofit an existing home, InSoFast EX 2.5 Panels provide drainability and breathability in a simple easy-to-install system. You won’t have to remove existing wood siding or trim boards and can incapsulate old lead paint siding rather than wasting time, energy and expense on abatement.

If you have a wall, InSoFast insulation panels can be attached to it. They can be applied universally to any interior or exterior wall assembly in both new and retrofit construction projects. Contact us today at (888) 501-7899 or online to start saving time and money!
