Shipping Containers # Shipping Container Insulation Shipping containers, while incredibly sturdy, are essentially thin metal boxes. This makes them highly susceptible to extreme temperature fluctuations (scorching hot in summer, freezing cold in winter) and significant condensation issues. Therefore, proper insulation is **absolutely critical** if you plan to use a shipping container for anything other than basic, non-sensitive storage, especially in a climate like Tasmania's. Spray foam insulation is widely considered one of the best solutions for insulating shipping containers due to its unique properties. ### Calculate your cost These are estimates only, a full quotation will be provided upon submission ![Shipping Container with spray foam insulation](https://sprayfoamsolutionstas.com/volumes/images/Applications/Shipping-Containers/_2048xAUTO_crop_center-center_70_none/7747/IMG_7230.webp) [ ![IMG 7232](https://sprayfoamsolutionstas.com/volumes/images/Applications/Shipping-Containers/_700x400_crop_center-center_70_none/7749/IMG_7232.webp) ](https://sprayfoamsolutionstas.com/volumes/images/Applications/Shipping-Containers/_2048xAUTO_crop_center-center_70_none/7749/IMG_7232.webp) [ ![Shipping Container with spray foam insulation](https://sprayfoamsolutionstas.com/volumes/images/Applications/Shipping-Containers/_700x400_crop_center-center_70_none/7747/IMG_7230.webp) ](https://sprayfoamsolutionstas.com/volumes/images/Applications/Shipping-Containers/_2048xAUTO_crop_center-center_70_none/7747/IMG_7230.webp) [ ![IMG 7229](https://sprayfoamsolutionstas.com/volumes/images/Applications/Shipping-Containers/_700x400_crop_center-center_70_none/7746/IMG_7229.webp) ](https://sprayfoamsolutionstas.com/volumes/images/Applications/Shipping-Containers/_2048xAUTO_crop_center-center_70_none/7746/IMG_7229.webp) [ ![IMG 7228](https://sprayfoamsolutionstas.com/volumes/images/Applications/Shipping-Containers/_700x400_crop_center-center_70_none/7745/IMG_7228.webp) ](https://sprayfoamsolutionstas.com/volumes/images/Applications/Shipping-Containers/_2048xAUTO_crop_center-center_70_none/7745/IMG_7228.webp) [ ![IMG 7221 2](https://sprayfoamsolutionstas.com/volumes/images/Applications/Shipping-Containers/_700x400_crop_center-center_70_none/7742/IMG_7221-2.webp) ](https://sprayfoamsolutionstas.com/volumes/images/Applications/Shipping-Containers/_2048xAUTO_crop_center-center_70_none/7742/IMG_7221-2.webp) [ ![IMG 5704](https://sprayfoamsolutionstas.com/volumes/images/Applications/Shipping-Containers/_700x400_crop_center-center_70_none/7724/IMG_5704.webp) ](https://sprayfoamsolutionstas.com/volumes/images/Applications/Shipping-Containers/_2048xAUTO_crop_center-center_70_none/7724/IMG_5704.webp) [ ![IMG 5701](https://sprayfoamsolutionstas.com/volumes/images/Applications/Shipping-Containers/_700x400_crop_center-center_70_none/7721/IMG_5701.webp) ](https://sprayfoamsolutionstas.com/volumes/images/Applications/Shipping-Containers/_2048xAUTO_crop_center-center_70_none/7721/IMG_5701.webp) [ ![IMG 7233](https://sprayfoamsolutionstas.com/volumes/images/Applications/Shipping-Containers/_700x400_crop_center-center_70_none/7389/IMG_7233.webp) ](https://sprayfoamsolutionstas.com/volumes/images/Applications/Shipping-Containers/_2048xAUTO_crop_center-center_70_none/7389/IMG_7233.webp) ### Conforms to Corrugation Shipping containers have corrugated (wavy) steel walls. Traditional insulation methods like batts require building a complete internal stud frame to create flat surfaces, which significantly reduces interior space. Spray foam, however, can be sprayed directly onto the corrugated metal, expanding to fill every curve and crevice, creating a seamless, uniform layer of insulation without the need for extensive framing. ### Unmatched Air Sealing The tiny gaps and seams in a shipping container are major points of air leakage. Spray foam creates an airtight seal that eliminates these drafts, preventing heat loss/gain and drastically improving energy efficiency. ### Pest Barrier The dense, sealed nature of spray foam prevents insects and rodents from entering the container through small gaps. ### Structural Adhesion Closed-cell spray foam adheres firmly to the steel, adding a layer of rigidity to the container walls. This can make the container even more robust and potentially reduce noise from flexing. ### Condensation Control Closed-cell spray foam is an excellent vapor barrier, preventing moisture from reaching the cold steel surface and stopping condensation in its tracks. This is a primary reason it's so highly recommended for containers. ### Longevity Once applied and cured, spray foam is a permanent insulation solution that will last for the lifetime of the container, requiring no maintenance or replacement. ### Thermal Performance Closed-cell spray foam offers a high R-value per inch (typically R1 – R1.5). This allows you to achieve excellent insulation with a relatively thin layer, again preserving valuable interior space. ### Sound Dampening Spray foam helps reduce external noise, making the container interior quieter and more comfortable, especially important if converting it into a living or working space.
