Transform your shipping container into a comfortable, code-compliant space with the Inserts Shipping Container Insulation Bundles from InSoFast—engineered for simplicity, durability, and performance. Whether your turning a shipping container into an industrial refrigeration unit, a storage unit or a jobsite office, the InSoFast Inserts provide a flat surface to install standard foamboard insulation to the walls and ceiling of your container without trapped air pockets. This system is ideal for applications where framing is not required.
The Insert bundle is compatible with any foamboard insulation, and will provide a continuous barrier to moisture when used with foamboard. The inserts eliminate air pockets that can cause a convective loop of air flow that will reduce the performance of your insulation and deposit moisture inside the wall.
With fast and DIY-friendly installation, InSoFast Insert bundles are designed for broad compatibility, but verifying container dimensions before ordering is important. Available in custom kits for sidewalls, end walls and ceilings, InSoFast gives you everything needed to insulate your container from floor to ceiling with durable, mold-resistant materials built to last.
