Spray polyurethane foams are a type of rigid high-density foam that is sprayed onto a substrate. The spray foam can be used for various purposes, such as insulation and sealing air ducts.
Types of Spray Polyurethane Foams:
There are two types of spray polyurethane foams: open-cell and closed-cell.
Open-cell spray foam is less dense and has a lower R-value than closed-cell foam. This type of foam is generally used for insulating purposes.
Closed-cell spray foam is denser and has a higher R-value than open-cell foam. This type of foam is generally used as sealant foam.
How is spray polyurethane foam installed?
Spray polyurethane foam can be installed by a professional or on your own. Professionals have the ability to install this type of foam with a machine. On the other hand, you can purchase an installation kit and spray polyurethane foam on your own.
How are spray polyurethane foams different from traditional insulation?
Spray polyurethane foam is a type of rigid high-density foam that is sprayed onto a substrate. The spray foam can be used for a variety of purposes, such as insulation and sealing air ducts.
Benefits of using spray polyurethane foam:
- Spray polyurethane foam can be used for a number of purposes, including insulation and sealing air ducts. With good insulation, heat flow is minimized and you may enjoy increased comfort, energy efficiency, and indoor air quality.
- Closed-cell spray foam can be used as a sealant to help reduce air infiltration in buildings. Sealing the building envelope can lead to improved comfort and energy efficiency.
- Spray polyurethane foam is resistant to heat flow, minimizing heat transfer by forming an insulating film on the surface.
- Open-cell spray foam is less dense and has a lower R-value than closed-cell foam. This type of foam is generally used for insulating purposes.
- Spray polyurethane foam provides good insulation because it is resistant to heat flow, minimizing heat transfer by forming an insulating film on the surface.
- Additionally, spray polyurethane foam can help to reduce air infiltration and improve the air seal of a building. This can lead to increased comfort, energy efficiency, and indoor air quality.

Procedural applications of SPF usually do not present serious health risks provided that manufacturers’ instructions are carefully followed. However, some individuals may have sensitivities to certain chemicals used in the formulation of SPF, and skin testing is recommended prior to use. Persons with respiratory problems, allergies, or other sensitivities should take special care when using SPF.
- Closed cell spray-applied polyurethane foam, referred to by some manufacturers as “rigid insulation” (R).
- Open cell or low-density spray-applied polyurethane foam. Open cell is typically about 50% the weight of an equivalent thickness of concrete.
- In either case, SPF can have a higher R-value per inch than fiberglass or cellulose insulation.
- Rigid foam is available in two formulations: “closed cell” and “open cell.”
- Closed cell rigid foam consists of small, gas-filled cells that are not interconnected. These cells are less permeable to moisture vapor and gases than open-cell foam. Closed-cell foam is less likely to suffer from moisture problems and is often used in roofing applications.
- Open cell rigid foam contains large cells that are interconnected. These cells are more permeable to moisture vapor and gases than closed-cell foam. Because of this, open-cell foam is often used for insulation purposes.
- Cellulose insulation is typically the cheapest choice since it is often just ground-up newspaper.
- Fiberglass batts are rigid boards that are inexpensive but can be tedious to install. They tend to perform better in cold climates than warm ones, however, because they do not breathe air as well as other types of insulation.
- Spray foam insulation is an airtight material that can be used to fill the gaps found in stud walls, floor cavities, and other areas of a structure.
- The R-value of spray foam insulation varies by the type of product that is being used, but it generally ranges from 6 to 9 per inch. This means that open-cell foam has a higher R-value than closed-cell foam.
With technonicol advancements, SPF insulation is now available in a closed-cell foam that is less permeable to moisture vapor and gases than open-cell foam. It should be noted that SPF insulation is not a fire retardant and should not be used in place of traditional materials, such as gypsum board or other ignition barrier products.
In conclusion, it should be noted that these foams are applied in either one or two-component forms of spray application. When mixed with an isocyanate or polyol, SPF can expand to 100 times its initial volume. It will then quickly cure and form durable expanding foam insulation that adheres tightly to many materials makings it difficult to be removed.
