Open Cell vs Closed Cell Spray Foam Insulation Comparison
Before we dive into the pros and cons of open cell vs closed cell insulation, it is important to note that they are both superior...Read More
Container insulation is particularly necessary due to the container’s composition. Typically, the containers exterior is composed of solid steel, this makes it extremely ineffective at preserving a separate temperature for the interior of the property. Climate also plays a big part in container insulation, considering how great of a conductor steel is, containers may need to be insulated according to their outside climate.
When insulating a shipping container, you are attempting to separate the conditioned airspace from the outside, essentially keeping the warmer side warm and not letting the heat escape out.
Blanket insulation in the form of batts and rolls, this form of insulation makes great use of fibres compressed for optimal insulation properties. This form of insulation is on the cheaper side, easy to install and requires minimal DIY work. Blanket insulation has various forms, each with their own benefits:
Fibreglass: Composed of recycled glass or superheated sand, rapidly spun into fibres. This is the most common form of blanket insulation and one of the cheap wall insulation methods.
Rock/Mineral Wool: similar to fibreglass but it is composed of minerals.
Cotton: Sourced from recycled denim. This form is a bit pricier but it has a high percentage of recycled contents, making it one of the more sustainable and environmentally friendly methods of insulation.
This form of insulation is specific to cavity wall and may require complete wall cavity containment prior to application of the insulation. This form of insulation is composed of macroscopic chunks of insulating product into a wall cavity. The various forms of macroscopic products are:
Cellulose: Recycled paper products shredded and air-blown into the cavity.
Loose-fill Fibreglass: Similar to the fibreglass blanket insulation, however, this form is not as compressed in order for them to be blown into the wall cavity.
Perhaps the most superior form of container insulation, this liquid-blown product hardens and expands into all nooks and crannies. The insulator forms a barrier that repels against air movement and halts the transference of heat, effectively separating the conditions between exterior and interior. Using spray foam insulation is extremely environmentally friendly due to its 100% water composition of the blowing agent and it uses zero harmful gasses.
Open-cell: This form is lighter, less tight and more expandable, in order to cover every crack, completely insulating from the outside. Open cell foam insulation has a lower R-Value per cm due to the more flexible composition.
Closed-cell: This spray foam insulation type is tighter and has one of the highest R-Value per cm, making it one of the most common forms of container insulation. It has great resistance to heat movement and transference, therefore it performs its job excellently.
Consider performance characteristics and how the insulation can be affected by open cell or closed cell structures, materials and entrapped gas.
The value of heat loss prevention. How well the product prevents the transmission of heat.
How well the insulator prevents air passing through the insulation and the container. How air permeable is the insulation.
How well the insulation prevents water vapor passing through and also retaining the water that can lead to mold growth.
Cost depends on the insulation material used and the cost of application and equipment usage. Some materials are easily applied compared to others.
Shipping containers can be used as homes or for commercial reasons. For residential usage, you’d want to build for sustainable reasons, therefore it is important to insulate sustainably. Insulating products hold different ecological impacts. We recommend spray foam insulation for eco-friendliness.
