Shipping containers are also known as intermodal containers and ISO containers. More often than not they are 2.6 metres high and the same width and come in 6.1 metre (20ft) and 12.2 metre (40ft) lengths.
Originally the containers were used to store and transport freight and products via road, rail and ship. However, they are now being used as static storage, offices, retail units and even living accommodation.
These steel containers conduct heat and therefore, they do not retain heat and often condensation will form on the inner surfaces of the steel. This is a problem when storing goods because condensation can be very damaging. Also if your shipping container is converted into a space where people are working or living a humid climate will be created and there will be an increased amount of moist air produced which will readily form surface condensation.
There are several traditional shipping container insulation methods, such as foam panels, mineral wool batts and foil insulation all of which are time consuming and inefficient methods because they all require mechanical fixings and joint sealing to prevent moist air reaching the cold steel surface and condensing.
Green Insulation UK apply closed cell spray foam insulation to the internal surfaces of steel containers, which is the most efficient way to insulate containers. The two-part foam insulation is sprayed directly on to the steel surface and it expands to form a completely seamless insulation layer with no gaps or joints and therefore, it eliminates the formation of condensation thus protecting any stored goods. A 25mm layer of our sprayed rigid foam is sufficient to prevent the formation of surface condensation and the foam can be left as the final finish. However, if the shipping container is to be occupied as an office or retail unit, stud walls can be created and increased thickness of foam insulation can be applied to achieve the optimum thermal values. Once the foam insulation has been applied it can be boarded over with plasterboard or similar. Our shipping container insulation will create a warm, dry area, which will be clear of condensation issues and help with reducing energy bills.
At Green Insulation we only use environmentally friendly materials, they are CFC free and have a zero Ozone Depletion Potential (ODP). We use closed cell foam, which is the only type of foam that is suitable for shipping container insulation. We only use foam systems that meet with the Class1 Spread of Flame rating to BS476 pt7. All the equipment and materials we use are delivered to site in a self contained van, which is sited near to the shipping container. The two components are delivered to the proportioning machine, which heats the chemicals to a low temperature and then through heated hoses to the spray gun. This is where the two components mix and form a rigid foam, the reaction time is very swift around 10-12 seconds. During this time the foam seals any joints cracks and hard to reach areas, and it creates a seamless insulated finish.
