About InSoFast Panels & Container InSerts
InSoFast CX Container Panels are specifically designed for the side walls of shipping containers. Their thin profile takes up only two inches of interior space. The panels are set up for an 11-inch repeating pattern of the corrugation and the panel size is 44” x 24”. They are installed horizontally with the studs running vertically to allow the studs to adhere to the ribs of the container.

The features of our CX Container Panels and InSerts include:
- R-11 wall panel
- Continuous insulation
- Built in framing
- Built in electrical raceways
- Integrated composite studs
- No special tools required
- Solid backing for drywall
- Save space, time and energy
- Universal insulation for floor, walls, ceilings, interior and exterior
Our end wall and ceiling inserts are specifically shaped sleeves of EPS foam that are designed to close up the container’s corrugation air gaps. Once glued in place with PL Premium 3X Construction Adhesive, the surfaces will be flush and ready for coverage in full InSoFast panels. Another excellent option is to utilize InSoFast Side Wall Inserts in conjunction with InSoFast UX 2.0 or InSoFast EX 2.5 panels to achieve maximum insulation and air-tightness.
Are Shipping Containers Durable?
Shipping containers are everywhere today and are being used as homes, offices, restaurants and shops. Why? The steel boxes are some of the most well-built, durable structures in the world.
The standard container is made from weathering steel (commonly known as CorTen), which was developed for its resistance to corrosion. The steel panels are first cut to size and then corrugated for extra strength. After welding the panels onto a reinforced steel beam undercarriage, doors and floor are installed, and the container is primed and painted with marine-grade paint to further protect it from the weather.
Once loaded with products, shipping containers are designed to be stacked on a container ship (up to 10 high). Standard containers are either 20-foot or 40-foot long. A 20-foot container can hold about 60,000 lbs. and has a typical lifespan of 10 to 12 years in shipping. After leaving shipping service, it can last another 10 to 15 years. Clearly, shipping containers are one of the strongest structures in the world!
Recycling or “upcycling” shipping containers into homes is an environmentally friendly approach because it avoids the energy intensive process of melting down the steel for another use. But, an unfinished steel shipping container can be too hot to live in during the summer and freezing cold in winter. It is also susceptible to condensation which can cause the steel to rust. You will need a good plan for adding insulation, and InSoFast can help!
