Open Cell Spray Foam Insulation

About Open Cell Spray Foam Insulation

Open cell spray foam insulation is a soft foam insulation product, which is utilized primarily in southern U.S. states for any construction type.

What Is Open Cell Spray Foam Insulation?

Open cell spray foam insulation is a low-density, nonstructural insulation product. The tiny cells of the foam are not completely closed – they are broken. Air fills the open space inside the material, making the foam softer than closed cell foam. It has many great performance features including reduction of air infiltration, increased energy-efficiency, quieter environment and increased living comfort. Foam insulation can also be applied in difficult-to-reach areas that other insulation cannot.

Open Cell Spray Foam Installation Process

When skilled installers use reliable equipment, applying open cell spray foam becomes a seamless process.

Preparation and Safety Measures

Before starting open cell spray foam installation, confirm that all materials, equipment, and supplies are on-site. You should be prepared to follow manufacturer guidelines for an efficient application. You also need to adhere to OSHA and EPA safety guidelines, including proper ventilation, PPE, and other specified measures to ensure a safe application.

Application Techniques

Application techniques for open cell spray foam vary by structure and specific needs for the area. These techniques can be mastered with guidance from experts, such as those with training and extensive experience with open cell spray foam application. It is recommended to adhere to the manufacturer’s application guidelines for even application. 

Curing and Setting Time

Open cell spray foam generally becomes tack-free within 5 to 60 minutes. Full cure is achieved in approximately 8 to 24 hours, depending on the specific product and site conditions. Review the manufacturer’s guidelines to find information about open cell spray foam’s curing and setting time.

Comparing Open Cell Spray Foam Insulation

Open cell spray foam has features that make it ideal for various applications, but there are other insulation options available.

Open Cell Spray Foam Insulation vs. Closed Cell Spray Foam

While the names are very similar, there are key distinctions between open cell spray foam and closed-cell spray foam. Open cell spray foam features partially encapsulated cells, giving it a more flexible texture compared to the rigid structure of closed-cell foam. Another key difference is in expansion: open cell spray foam expands at a 300:1 ratio, whereas closed-cell is at 30:1. Other differences between open cell spray foam and closed-cell spray foam are detailed below.

Density and R-Value

• Open-cell: With an R-value of around 3.5 per inch, open cell spray foam is a lower-density insulation. 
• Closed-cell: Offering up to 7.5 per inch for R-value, closed-cell spray foam is a denser insulation option.

Moisture Resistance

• Open-cell: Open cell spray foam doesn’t provide a vapor barrier and it may need to be added depending on the climate.
• Closed-cell: Closed-cell spray foam is naturally water resistant, making it a good choice for moisture-rich environments.

Cost Considerations

• Open-cell: With its high yield, open cell spray foam produces more finished material from the same quantity of raw materials compared to closed-cell spray foam, making it generally more cost effective.
• Closed-cell: While closed-cell spray foam usually has higher upfront costs, its higher density also gives potential to greater savings in energy efficiency. 

Open Cell Spray Foam Insulation vs. Other Insulation Types

While fiberglass and cellulose are common insulation options, open cell spray foam offers several advantages. For example, open cell spray foam is known for providing superior soundproofing and air sealing, which improves energy efficiency in a structure. When compared to cellulose, which can settle over time and create gaps in coverage, open cell spray foam has the advantage of expanding to completely fill hard-to-reach areas for consistent thermal performance. Its flexibility and long-term durability make it a reliable choice for both residential and commercial applications.
