From paints to pesticides, most chemical products have storage temperature parameters strictly dictated by their manufacturers. Extreme seasonal variations in the UK can make the storage of chemicals in barns, warehouses or lock-ups difficult to regulate.
Improper storage can lead to a loss of performance or total stock write-off resulting in huge financial losses for your company. Spray foam insulation is a cost-effective way to regulate temperatures and protect your chemicals.
With seamless adhesion to every inch of your chemical store, spray foam insulation provides an airtight thermal barrier that keeps temperatures consistent. Additionally it is a fast, effective and inexpensive solution helping to minimise disruption to your business.
Both ThermoFoam Open and Closed-Cell can be applied for consistant thermal regulation in chemical storage facilities. The type of structure and its condition will determine the choice of foam but we generally recommend 50-100mm of Closed Cell and 150-200mm of Open-Cell.
Although we install both open and closed-cell products, not all spray foams are created equal, therefore we are always careful to respect the application uses for both products in achieving the correct install for your building.
Open Cell is a low density sponge like foam, making it an effective barrier against noise transmission and adds good thermal performance to a building.
When used in areas that are susceptible to moisture intrusion, Open Cell foam will absorb this moisture which can create issues within the building or structure it is applied to.
To overcome this, we always recommend an application of Closed Cell foam for buildings that have metal, asbestos or cement roofs. These are commonly held together by bolts and gaskets, which when rusted or broken, act as the first entry point for moisture.
Closed Cell is a high density rigid foam, that acts as a very good vapour barrier. It helps to bind all aspects of a roof substrate to prevent the degradation or loosening of bolt fixings and adds structural integrity.
As little as 25mm of Closed Cell insulation will eliminate condensation whilst an application of 50mm will provide exceptional thermal performance. Both depths offer strong adhesion to the substrate to future-proof its integrity.
During the install process, we insist that the building is free of chemicals and belongings to protect from any over spray. The process of installing spray foam creates significant fumes and our installers wear specialist breathing apparatus. Once the Spray Foam has expanded and cured, it becomes inert and doesn’t release any fumes or smells that may affect your staff or your stock.
We always cover and protect floors and any other items whilst we are spraying the insulation because tiny droplets, known as over-spray, tend to fall to the floor. We certainly don’t want you or your stock to be left covered in tiny droplets of insulation as it’s quite the task to clean it off. The insulation will do nothing but protect your stock once installed.
We install a Class 1 fire rated Closed Cell Foam in chemical stores when it’s left exposed without an ignition barrier to protect it. We wouldn’t recommend choosing an Open Cell Foam because it’s fire rating is usually not acceptable in such spaces. In our experience, where buildings have caught fire with a good Class 1 fire-rated Closed Cell, the foam will char but not ignite.
Fire safety has never been so important, therefore, choosing the right brand of foam for your install should be an important consideration for you. There will be some foam companies who suggest that an Open Cell Foam will be sufficient but aside from it’s fire rating, the density of the product is like a sponge and will absorb water on failing roofs.
If the insulation is to be left exposed and you want a different colour, it can be painted a different to blend with its surroundings. We use specialist paint coatings that can add additional Class 0 fire resistance and vapour control layer coupled with a decorative colour.
The finished surface of Closed-Cell Spray Foam is much like an orange peel texture whereas Open-Cell Spray Foam is very absorbent allowing paint to soak into it. We recommend that Spray Foam Insulation is coated using an Airless Spray Paint machine for maximum adhesion and to ensure that a seamless colour layer is the end result.
We know that any major works to a chemical storage building can potentially disrupt the day to day trade of the business. We will always work around you to ensure that we keep any disruption to a minimum and that you can get your business back in operation as soon as possible.
One install team can complete up to 250 square metres in a day and where the size of the building is vast, we can mobilise more than one spray rig to speed up the process. Generally speaking, you are looking at no more than 1-2 days of disruption for less than 500 square metres.
