Why Insulate Your Shipping Container Floor?
Insulating your shipping container floor is crucial for several reasons, all of which contribute to a more comfortable, energy-efficient, and durable living or working space.
Temperature Control
Shipping containers are made from Corten Steel, which can become extremely hot or cold depending on the outside temperature. Without proper insulation, the interior can be unbearably hot in summer and freezing in winter. Insulating the floor helps maintain a stable internal temperature, making the space habitable year-round.
Moisture Prevention
Moisture can be a significant issue in shipping containers, leading to mold and mildew, which can damage the structure and pose health risks. Insulation acts as a barrier, preventing moisture from seeping through the floor. As Tyler mentioned in a recent container discussion, insulating the underside of the floor with spray foam followed by EPS panels can effectively create a vapor barrier, reducing the risk of moisture buildup.
Energy Savings
Insulating your shipping container floor can lead to significant energy savings. By reducing the need for external heating and cooling, you lower your energy consumption and utility bills. The InSoFast insulation panels offer an R-value of up to 11, making them an excellent choice for conserving thermal energy and reducing overall energy costs.
Comfort
A well-insulated floor contributes to the overall comfort of your shipping container space. It ensures that the interior remains at a comfortable temperature, making it a pleasant environment to live or work in. InSoFast panels, for example, are designed to be easy to install and provide a durable, comfortable foundation for your flooring.
Durability
Insulation also adds to the durability of your shipping container. By protecting the floor from extreme temperature fluctuations and moisture, you extend the lifespan of the container. This is particularly important if you’re using the container in a location with harsh weather conditions. Tyler’s design considerations for his Southern Ontario container home highlight the importance of protecting the floor from the cold, windy winters to ensure long-term durability.
By insulating your shipping container floor, you not only create a more comfortable and energy-efficient space but also improve its durability and lifespan. Next, we’ll explore the different types of shipping container floor insulation available and their benefits.

By choosing the right type of shipping container floor insulation, you can ensure your container remains comfortable, energy-efficient, and durable. Next, we’ll dive into the installation process to help you get started.
Installation Process for Shipping Container Floor Insulation
Preparing the Floor
Before you start, clean the floor thoroughly to remove any dirt, debris, or grease. This ensures a smooth surface for the adhesive to bond properly.
Surface preparation is crucial. Inspect the floor for any rust or damage and repair it. Use a wire brush or sandpaper to remove rust spots, and apply a rust-inhibiting primer if necessary.
Measuring is the next step. Measure the dimensions of your shipping container floor accurately. This will help you cut the insulation panels to the right size, ensuring a snug fit.
Applying Adhesive
Choosing the right adhesive is important. For InSoFast panels, a construction adhesive like Liquid Nails or a similar product works well.
Application techniques vary, but generally, you’ll apply the adhesive in a zigzag pattern across the floor. Make sure to cover all areas where the insulation panels will be placed.
Placing Insulation Panels
Alignment is key. Start from one corner of the container and place the first panel. Ensure it’s perfectly aligned with the edges of the floor.
Securing panels is straightforward with InSoFast panels. Press the panel firmly onto the adhesive. The embedded studs in these panels make it easy to attach additional flooring on top.
Sealing Edges
To prevent moisture and improve insulation, seal the edges of the panels with a vapor barrier tape. This step is crucial for moisture prevention and maintaining the integrity of your insulation.
Finishing touches include checking for any gaps between panels and filling them with spray foam or additional adhesive. This ensures a tight seal and maximizes the insulation’s effectiveness.
By following these steps, you can successfully install shipping container floor insulation and create a comfortable, energy-efficient space. Next, we’ll answer some frequently asked questions about shipping container floor insulation to help you make informed decisions.
