You may be aware of the importance of making load-bearing walls the strongest part of any commercial building. It is not always known, however, that for resilient, weatherproof buildings, it’s also imperative to pay extra attention to roofing systems.
Spray Polyurethane Foam (SPF) works well in reinforcing the entire structure of a commercial building.
Why Focus on Walls and Roofing Systems?
Your walls withstand various elements, from the constant weight of the roof to external forces such as high winds. So, when the walls of a building aren’t strong enough to endure the roof’s weight or any other external force, it can collapse to relieve the weight.
On the other hand, commercial roofs often stretch across vast distances, bearing the tensile strength of various materials such as the roofing panel or frame. Even with sturdy walls, a roof’s section may still break down due to unbearable weight.
Roofing systems are especially prone to collapse during bad weather, as ice or snow tend to add to its weight.
What’s in SPF Insulation?
As its name suggests, spray foam is a liquid-based compound that quickly expands into a foam once sprayed. But this is just a simple way to describe SPF.
SPF has two main components: isocyanate on “Side A” and polyol on “Side B.”
Isocyanates such as methylene diphenyl diisocyanate (DMI) make SPF insulation strong and rigid. It is also the component that provides surface protection to the SPF insulation.
Polyol is the main component of Side B, although it may also integrate other chemicals such as flame retardants. The polyol blend gives the foam dexterity and expansive characteristics. It also provides spray foam the flexibility that helps with adhesion and ease of installation.
Many SPF installers create their own blend to improve the durability and performance of their SPF insulation products.
How Does Spray Foam Insulation Make Buildings Resilient?
As mentioned earlier, spray foam is liquid during application, but it expands instantly when sprayed into an open cavity. And as it expands, it also adheres to any substrate it comes in contact with. It permeates into any opening of the contact surface and seals off gaps of any size, from tiny fissures to large cracks and holes.
Soon after the foam is done expanding, it starts to harden. Hardened foam naturally bonds with any element it comes in contact with. This is why spray foam has the ability to hold together any part of your building that connects to the foam, even those hard-to-reach areas. When forces such as high winds hit, the structure has a higher and more solid resistance to extreme pressure.
