InSoFast Panels simplify the wall assembly while helping create quieter, warmer, healthier, and more comfortable spaces — from basements and garages to exterior retrofits and shipping containers.
InSoFast Panels are engineered as a complete wall system, not a collection of separate products.
Traditional wall assemblies rely on multiple layers, materials, and installation steps to increase labor, complexity, and opportunities for failure. InSoFast combines continuous insulation, integrated framing, moisture management, and wiring pathways into one simplified assembly designed for real-world construction.
Built to reduce thermal bridging, control condensation, and improve comfort in basements, garages, exterior retrofits, and other challenging spaces.
Integrated studs, electrical raceways, drainage channels, and interlocking panels reduce installation steps and simplify the build process.
Traditional framing can cost inches on every wall. InSoFast helps maximize usable interior space while improving thermal continuity and overall comfort.
Made from inorganic materials that resist mold, rot, rust, and moisture-related deterioration.
Install quickly using tools you already own with a system designed for repeatable, predictable results.
