InSoFast patented and patent-pending EPS foam panels are the best insulation for exterior walls and can be used in new construction as well as for exterior retrofitting under siding, brick, stone, stucco and other finishes.
If you prefer easy, do-it-yourself projects, you’ll love InSoFast! Our closed-cell, injection-molded EPS foam panels are very lightweight and can be easily cut and installed on the jobsite with a handsaw, handheld jigsaw or sabre saw, glue and a and a caulk gun.
Exterior Wall Insulation
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 R-value outperforms traditionally framed R-15 batt walls.
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, providing drainability and breathability in a simple easy-to-install system.
Our panels are manufactured using a flame-retardant foam and are classified as rigid foam plastic insulation. They fall into the same class as pink, blue and yellow insulation boards and are required by code to be covered by ½” drywall or other approved 15-minute thermal barrier (IBC 2603.4).
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.
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.
When using InSoFast to retrofit older structures, you won’t have to remove existing wood siding or trim boards and can incapsulate old lead paint siding instead of wasting time, energy and expense on abatement.
