Popular SPF Myths That Have Been Debunked

Spray polyurethane foam has seen great adoption among many building and property owners because of its excellent price and dependable installation procedures. However, SPF is still far from being the norm for commercial roofing because many still believe many myths about it that have been debunked throughout the years.

Here are five popular SPF myths that have already become obsolete.


SPF is affordable roofing material. Even if it’s a newer technology, it’s not as expensive as many make it out to be. 

Ecodur 201 is resistant to water, UV rays, and extreme temperatures, and it lasts for years without any maintenance. While it might have high initial costs, the long-term lifespan and dependability are enough to make it a great material to use.


Spray polyurethane foam is one of the strongest materials for roofing and cladding in modern construction because of its high insulative properties. It has a long-term R-value of 6.25 per inch thickness, which is the highest of any insulation material.

Additionally, spray polyurethane foam is vapor-permeable, which means that it does not trap air inside. This, combined with its insulation properties, make it a perfect material for any construction project.

SPF is indeed a toxic roofing material, which is why its installation professionals always wear proper personal protective equipment and consisently train for installations. They do this to ensure they do not commit any mistakes during installation that can lead to personal dangers.

During installation and spraying, SPF is airborne, which is why installation teams take time to wrap everything in plastic to ensure no SPF material escapes. Once the material is cured after 24-72 hours, no inhalation risk can damage the property owner’s health.

Easily Problematic Installations

Spray foam is the easiest construction material to install because it can be applied in any shape and direction as long as the area is large enough for the machine. It does not need to be cut like traditional materials. This allows for faster installation and more accurate adding of insulation.

The spraying aspect of SPF makes it one of the best materials for any roofing and cladding project. 

Many in-house teams who have had experience using SPF cans from local suppliers do not possess the knowledge and equipment to ensure all SPF methods are effective. 

We highly advise that you work with professional SPF applicators, such as us at Ener-Spray to prevent problematic installations.

Additional Structuring Requirements

Spray polyurethane foam does not require any additional structures during installation because it expands to fill all the nooks and crannies of the desired area. It also expands to form a water-resistant seal. With this in mind, it’s easy to see how SPF doesn’t require any additional structuring requirements.

SPF can preserve well-functioning fragments of aged single-ply roofs by spraying over them and filling their cracks. In doing so, you won’t need to tear down your old roof. Instead, you’ll be waiting for 24-72 hours until the material starts to cure.
