The Major Difference Between Fire-Rated and Regular SPF Roofs

Spray polyurethane foam (SPF) is one of the best materials you can use for external protection against the elements. However, SPF roofing has different fireproof ratings. Truthfully, fireproof SPF roofs are a huge advantage, but it’s far more expensive than their regular counterparts.

If you’re wondering about the major differences between the two, especially on fireproof roofing’s technical aspects, here are a few things to help you differentiate. Added costs do bring many benefits, as you’ll read below.

Certified and Regulated Performance

Fireproof roofing has a different set of manufacturer regulatory guidelines. Manufacturers use dense polyurethane, which carbonizes during a fire. Doing so prevents the structure from collapsing and smoke from existing rooms until polyurethane’s physical capacity has reached its limit.

All SPF can reach a certain physical capacity to prevent fire collapse. However, specialized fire-resistant SPF can deliver exceptional structural protection that tests and repeatable situations have greatly proven.

Non-Combustible and Smoke-Smothering

Similar to structural resistance against fires, all SPF have non-combustible and smoke-smothering properties. You can trust that an SPF roof can stay intact and contain fire sources during the entire event’s duration.

On the other hand, not every SPF roof can deliver the best combustibility and smoke resistance possible. 

Certifications and regulations guarantee the quality and resistance of all manufactured fire-resistance SPF roofs. Additionally, manufacturers can provide fire performance estimates with the smallest margin of error possible.

Insulation-Grade Materials

Insulating capacity is one similarity between fire-rated and regular SPF roofs. The material’s thickness plays a small role in providing insulation. Additionally, the seamless, zero-pore material guarantees the slowdown of air and sound molecules passing through your property’s walls.

Furthermore, the applicator’s installation technique plays a big difference. Thicker layers of SPF doesn’t mean better. However, addressing every possible problematic air and sound passage is critical.

Construction-Based Applications

Open-cell SPF is an immensely-capable construction material. On its own, it can fill unnatural gaps between concrete, wood, and other materials. However, it is quickly malleable and stretches easily.

On the other hand, closed-cell SPF can provide exceptional protection against outside elements. However, it does not perform proper wall insulation on its own. Combined with open-cell SPF to fill the gaps between the materials, they can deliver better insulation performance.

Lastly, some construction material manufacturers have started incorporating SPF as a priority material for concrete reinforcement too.

Relies on Dependable SPF Applicators

Licensed SPF applicators have the most qualification to deliver the best results for all SPF projects. You must find a reliable applicator, such as Ener-Spray, for all your SPF roofing needs. 

Furthermore, some SPF applicators might specialize in roofing. Others can specialize in general applications. Make sure that you choose the most experienced applicator for the type of project you have.
