A shipping container is a large, standardized, reusable container used for the intermodal transport of goods. These containers are designed to be easily transferred between different modes of transportation, such as ships, trains, and trucks, without unloading and reloading their contents. They come in various sizes and types, but the most common sizes are 20 feet and 40 feet in length. Shipping containers are typically made of steel, which provides strength and durability, and are equipped with secure locking mechanisms to protect the cargo.
Insulating a shipping container is essential for creating a comfortable and energy-efficient living or working space. Shipping containers, typically made of steel, are prone to temperature extremes and condensation. Proper insulation addresses these issues and improves overall usability.

How To Insulate A Shipping Container Or Metal Building Without Framing
The Equipment Checklist Includes:
- Reflective tape
- A utility knife
- Perforated insulation pins with caps
- Heat gun (for sealing seams of 10M).
If framing the container with wood, model the install methods of how to insulate a pole barn (retrofitting section of page).

Step 1: Put a glob of glue on the base of the pin. Press the base of the perforated pins on to the sheeting. It's fine that the adhesive oozes through the holes of the base (you can smooth it out if you want). This part of the adhesive helps hold the anchor pin on to the metal. Space pins 1 per 2 square feet. Allow 24 hour cure time. The cure time can vary depending on the temperature and humidity
Step 2 (optional): Add Spacers to the pins on the walls - While the pins are bonding to the metal, prep the foam board spacers. Cut 2" x 2" pieces of 3/4" or 1" foam board. It provides an air gap which optimizes the performance of the insulation. Push the square foam pieces all the way down the pin. If you prefer no to use the spacer, don't push the insulation flush to the metal. Rather, leave the insulation off the the metal (approximately 1) inch to optimize performance.

Step 3: Push the insulation on to the pin. Once it's through the pin, push the cap onto the pin and press it down to secure the insulation.
Step 4: Once the insulation is secured, snip the end of the pins. You may also want to apply tape over the cut tip of the pin to avoid someone getting cut.
Benefits of Insulating a Shipping Container
1. Temperature Control: Maintains a comfortable indoor temperature, reducing the need for heating and cooling.
2. Condensation Prevention: Prevents moisture buildup, which can lead to rust, mold, and mildew.
3. Noise Reduction: Reduces noise from outside and within the container.
4. Energy Efficiency: Lowers energy costs by improving thermal performance.
5. Extended Lifespan: Protects the steel structure from temperature fluctuations and moisture damage.
