For centuries, roofers have been trying to figure out what the best insulation method is to keep the warmth in, and the cold out.
Think of old countryside cottages, with their thatched roofs, and now think about what might be up in your loft, glass wool (fiberglass) maybe? Now, imagine you had a business premises, a commercial site where dozens of people were working each day. You’d want that place to keep the warmth in and the cold out, right? Right.
In this article we look at what we believe to be, as Spray Foam Experts, the best option on the market for commercial roof insulation. We break this recommendation down into four reasons as to why closed cell spray foam system for commercial roofs is the best.
Closed Cell Spray Foam is lightweight & easy to transport
As far as closed cell spray foam system for commercial roofs goes, spray on insulation packs incredible power into such a small transported space. Arriving in liquid form, it has the ability to expand to around 100 times of its original size upon application. The spray foam is super easy to transport, and because it does not take up the same sort of room per square metre as other insulation types, it uses a smaller carbon footprint for delivery.
Closed Cell Spray Foam is eco-friendly
Air leakage can account for up to 40% of the warm air loss in a building, with uninsulated walls accounting for even more. So, by using closed cell spray foam system for commercial roofs, you will be able to considerably reduce your energy consumption, and thus your energy bills. As well as this, spray foam is rated as 0 for Ozone damage, making it the most eco-friendly option on the market, and can even boast the lowest carbon footprint for transport thanks to the liquid form it arrives in.
Closed Cell Spray Foam is airtight
Since spray foam expands in volume by up to 100 times after spraying, it pushes its way into all of the cracks and voids to form a complete seal. This seal is the best for commercial roofs, as it provides insulation to a design feature that was perhaps built without keeping warmth or energy in mind.
Sagging is completely avoided thanks to the spray foam’s ability to adhere to surfaces firmly, negating its way around one of the greatest problems that comes with fiberglass insulation and results in cold bridging. The airtight nature of spray foam against surfaces and in cracks, crevices and hard-to-reach places is wholly impressive, but that just tackles air loss…
Closed Spray Foam System is an incredible insulator
The difference between an open cell and a closed cell spray foam system is that closed cell has a much higher ‘R value’, this pertains to its heat retention abilities. This means that closed cell spray foam allows far less heat to escape, or cold to enter. Generally, open cell is a bit cheaper than closed cell, but this is for two reasons:
- firstly, it is permeable to water, meaning vapour can get through it,
- secondly, like we mentioned above, it doesn’t have such great insulation properties.
Because of closed cell foam’s adhesive-like physical composition, it also adds structural support to ceilings and roofs during assembly.
Closed cell spray foam system conclusion
Have these four reasons done enough to convince you of the benefits of closed cell spray foam system for commercial roofs? If yes, great! Nothing pains us more than bad insulation and bad information regarding insulation, so we hope you’ve been well informed at the very least!
