SPF Insulation for Metal Buildings: 3 Safety Considerations

Now that today’s marketplace is adopting better and more sustainable building code compliance, spray polyurethane foam (SPF) insulation is a timeless and versatile material that has become valuable in construction projects like roofing or wall insulation for metal buildings. 

What is Spray Polyurethane Foam (SPF) Insulation for Metal Buildings?

Looking closer, SPF is made of isocyanate and polyol resin that is applied to surfaces to provide insulation. There are two primary types of SPF insulation for metal buildings – open-cell foam, which provides air sealing but allows water and vapor to enter. 

Open-cell foam is particularly beneficial in hot climates, and it is generally the cheapest option. While it provides better comfort, mold growth resistance, and impressive soundproofing, it’s a prime choice for furnishings more than insulating metal panels. 

Closed-cell foam, on the other hand, offers premium insulation as water, moisture, air, and vapor are non-permeable. 

It’s a perennial favorite in commercial roofing systems as SPF is a self-adhering material that can effectively boost a building’s energy efficiency with its unparalleled thermal, air, moisture, and air barrier properties. With that in mind, closed-cell foam is often the ideal choice when deciding on insulation for metal buildings. 

The Importance of Proper Foam Insulation for Metal Buildings

SPF insulation is highly beneficial, but it requires just as much precaution during the installation. The factors below should help ensure the installation is following the proper guidelines for maximizing the material’s performance: 

Factor #1: Equipment Care

Before anything else, the key to a successful installation is to ensure the equipment is working in top-notch condition. While these tools are built to withstand the abuse, caring for SPF installation equipment can make all the difference in ensuring the results are successful. 

With that in mind, it’s best to check if the contractors have some spare parts to minimize the downtime in case there’s a problem mid-installation. 

Factor #2: Proper Temperatures

All SPF chemicals and other materials used in the process come with a suggested temperature range set by the manufacturer. It’s best to stick to this recommendation as it guarantees the lifespan of your SPF and preserves its performance. 

Failing to comply can compromise the success rate of its application, so be sure to stick to the right ambient temperature and humidity that is optimal for SPF installations. 

Factor #3: Surface Evaluation

While most SPF insulation materials can easily adhere to various surfaces, it’s still better to install it on areas that are completely dry and free from debris, gunk, grease, oils, and other specks of dirt that can negatively impact its adhesion. 

SPF insulation for metal buildings can also work in various weather conditions, though those that come with fire protective coatings are best installed when there is no visible ice, frost, or moisture on the work surface.
