What is Spray Foam Insulation?

Spray foam is a mixed composite of polyol and isocyanate. When the two components come together, they react and expand, then harden up in a foam. It is capable of expanding, which makes it highly effective in filling a space, or creating a tight barrier on a crack, joint, or space, making your home airtight. It comes in two different types: open-cell insulation and closed-cell insulation.

  • Open–cell spray foam: This material is spongy to the touch and light, perfect for indoor applications where a softer material is required. Since it is spongy, it is not as good as a thermal barrier as the closed cell. Open–cell spray foam offers a better sound dampening effect.
  • Closed–cell spray foam: The R–value is higher, and it is denser and more rigid. As a result, it is more effective for insulation. Moreover, it can be used in both dry and wet areas because of its ability to resist moisture.

The R-value is a measurement used to determine the effectiveness of insulation materials in preventing heat transfer in and out of a space. A higher R-value signifies better insulation performance.

The Major benefits of this type of Insulation

Spray foam insulation offers a multitude of advantages that make it an exceptional choice for both residential and commercial properties. Its unique expanding properties create an airtight seal, significantly improving energy efficiency and reducing utility costs.

This type of insulation not only acts as a moisture barrier but also provides excellent soundproofing and enhances the structural integrity of buildings. Additionally, spray foam insulation is renowned for its durability, maintaining its effectiveness and form for many years, unlike traditional insulation materials.

  • Energy Efficiency: Reduces energy costs to an excellent level, as it makes an airtight seal that is impregnable to the leak. This affects the efficiency of the cooling and heating systems positively and hence, will reduce the utility bills.
  • Moisture Barrier: This acts as a moisture barrier, preventing water from entering the walls and forming mold and mild dew. This is very beneficial in places with high humidity.
  • Soundproofing: Open cell spray foam insulation is a good source of soundproofing, which can be used in homes in loud noise environments or for creating silent rooms.
  • Structural Strength: Closed-cell spray foam can also strengthen the building structurally since it is denser in nature, making the building wind-resistant and protected from other forces.
  • Durability: Spray foam insulation is durable and long-lasting. Unlike traditional insulation materials that may sag or settle with age, spray foam maintains form and function for many years.

Principal uses of Spray Foam Insulation

Spray foam insulation is incredibly versatile, offering effective solutions for a wide range of applications. Whether it’s residential, commercial, or industrial, this type of insulation delivers superior performance in maintaining optimal temperatures, enhancing energy efficiency, and providing long-lasting protection against environmental elements. Its adaptability and effectiveness make it a preferred choice across various settings.

  • Residential Uses: Spray foam insulation is extensively used to insulate crawl spaces, basements, walls, and attics in houses. This results in the creation of a cozy habitation by maintaining even-house temperatures.


  • Commercial Applications: This insulation is used with the intention of reducing operating costs and bettering energy efficiency. It is highly applicable in retail shops, offices and warehouses.


  • Industrial Applications: It also applies in industrial settings to insulate storage tanks, pipelines and other equipment. It can withstand very high and low temperatures, making it feasible for many industrial applications.

How it is Applied?

Spray foam insulation is the application of spray foam as an insulation product. This is done in the following steps:

  • Cleaning and Preparation: This will be done at the wanting area of insulation. This will ensure maximum adhesion. Dirt and outdated materials of insulation are done away with.


  • Mixing: This is done with a spray gun. The two ingredients needed to form the foam, polyol resin, and isocyanate, are mixed. Then, the mixture is sprayed on the surface.


  • Expansion: The foam will swell up when it comes into contact with the cracks and void to fill them up. It expands, then hardens quickly to create a seal.


  • Curing: The foam finally takes some hours to harden. As it cures, it continues to expand to ensure that there is a firm grip with the surface.


  • Trimming: Extra spray foam resting on the surface is cut, getting a clean, smooth surface.

Is Spray Foam Insulation Safe?

Applied properly and by a professional, spray foam insulation is considered safe after a minimum of 24 hours. In certain situations, the insulation installers may recommend that homeowners stay out of the house for 48 hours as a precautionary measure to avoid inhalation of fumes. Once the curing process is complete, homeowners can rest assured that they will not have to worry about chemical inhalation.

Health Considerations
When appropriately installed by professionals, like Foam Co experts, insulation is safe. However, chemicals used in installing this are harmful when it is inhaled or gets into contact with the skin. Proper ventilation when working with spray foam insulation and being out of the space for curing is important.

Environmental Impact
While foam insulation contributes to environmental sustainability by saving energy and reducing greenhouse gas emissions, there are concerns about the chemicals used. Foam Co ensures the use of eco-friendly products to minimize this impact​.
