CX-44 InSoFast Container Panel – 5 Per Box

CX-44 R-11 Shipping Container Insulation Panels Transform your shipping container into a comfortable, code-compliant space with the CX-44 Insulation and Framing Panels from InSoFast—engineered for simplicity, durability, and performance. Whether you’re creating a container home, office, or secure storage unit, the CX-44 delivers a complete system that removes the headaches of traditional framing and insulation. The CX-44 panel is a one-piece solution for framing and insulating sidewalls and works best on containers with minimal dents. Other container surfaces use our two-part flat panel and insert system. If your container has more than a few dents, we recommend the flat panels + inserts kits for easier fitting around dented surfaces. The CX-44 bundle provides a 2″ profile off the wall and delivers R-11 continuous insulation (outperforms R-15 framed walls) and a continuous moisture barrier. These panels outperform batt insulation and traditional foamboard by eliminating trapped moisture, condensation, rust, and mold risk. The low-profile design preserves usable interior space while maintaining thermal efficiency—ideal for compact conversions. Installation is fast and beginner-friendly. Built-in framing and integrated electrical raceways let you rough-in wiring and prepare for finishes using standard tools—no special equipment or complex framing required. Tongue-and-groove edges ensure a tight, continuous fit, and proprietary glue strips allow secure adhesive mounting directly to container walls. CX-44 bundles are designed for broad compatibility, but verifying container dimensions before ordering is important. Whether you’re a homeowner seeking energy savings and year-round comfort or a contractor aiming to reduce labor and material waste, CX-44 delivers code-compliant performance and cost-effective efficiency. InSoFast’s CX-44 bundles are more than insulation—they’re a smarter way to build. Available in custom kits for sidewalls, end walls, ceilings, floors, and doors, CX-44 gives you everything needed to insulate and frame your container from floor to ceiling with durable, mold-resistant materials built to last.   IMPORTANT:  Verify shipping container dimensions before placing an order.
