Types and Properties of Spray Foam Insulation
Spray foam insulation is a cutting-edge solution that enhances energy efficiency by creating an airtight envelope within the building structure. This property significantly reduces convective heat transfer, keeping interiors warm in winter and cool in summer.
The two main types of spray foam insulation are:
Closed-cell Spray Foam: This type is known for its high density and compact cell structure, which are filled with a gas that helps the foam expand to fill the gaps in the building structure. It boasts an impressive R-value, providing excellent thermal resistance and moisture barrier properties, making it ideal for areas susceptible to water. Due to its density, closed-cell foam also adds structural strength to walls.
Open-cell Spray Foam: Characterized by its softer, more flexible texture, open-cell foam has a lower density and is filled with air, which gives it a spongy texture. This type of insulation is cheaper than closed-cell foam but has a lower R-value and is not recommended for areas prone to moisture. However, it is excellent for soundproofing and is easier to apply in large areas.
Both types expand upon application, sealing gaps, and creating an effective barrier against air leaks, which significantly improves the energy efficiency of a home.
Installation of Spray Foam Insulation
Installing spray foam insulation involves a precise and controlled process. A two-component mixture is sprayed into the desired area, where it rapidly expands to form a continuous, airtight seal. This method is suitable for a variety of applications including walls, roofs, floors, and around HVAC systems.
The process requires skilled professionals equipped with the necessary safety gear, as the chemicals involved can be hazardous before they cure. The installation involves:
- Preparation: Removing any old insulation and preparing the surface for application.
- Mixing: Combining the two chemical components that react to form the foam.
- Application: Spraying the mixture into the target areas, where it expands and hardens.
- Curing: Allowing the foam to set, which can take several hours.
The versatility of spray foam makes it ideal for insulating irregular shapes and sizes, offering a comprehensive solution that traditional materials cannot match.
Cost of Spray Foam Insulation
Spray foam insulation is generally more expensive upfront than traditional insulation types like cellulose, rigid foam, and batt insulation. The cost depends on several factors including the type of spray foam (open-cell vs. closed-cell), the thickness applied, and the area being insulated.
Closed-cell foam is typically more expensive due to its higher R-value and superior moisture resistance. Open-cell foam, while less costly, may not be suitable for every application due to its lower R-value and inability to block moisture effectively.
When compared to other insulation types:
- Cellulose and Batt Insulation: These are usually less expensive than spray foam but do not provide the same level of air sealing or moisture resistance.
- Rigid Foam: While offering a higher R-value than some batt insulations, rigid foam does not conform to irregular surfaces as well as spray foam and may leave gaps if not properly installed.
Despite the higher initial cost, spray foam can result in significant energy savings over time due to its superior air sealing and insulating properties. Homeowners should also consider potential rebates and tax incentives that can offset the initial investment. Additionally, the improved comfort and reduced energy bills often justify the cost difference compared to other insulation methods.

Frequently Asked Questions about Spray Foam Insulation
Spray foam insulation creates an airtight envelope within the building structure, effectively sealing against convective heat transfer and preventing heat from escaping through gaps in the building envelope. It comes in two main types: closed-cell foam and open-cell foam, each with different properties and applications. Closed-cell foam provides stronger resistance against moisture and air leakage, while open-cell foam is lighter and less expensive.
There are two broad categories of foam spray insulation solutions: closed-cell and open-cell. In closed-cell foam insulation, cells are closed and filled with a gas allowing the foam to expand and fill the space around it. The high-density cells provide for a higher R-Value. Alternatively, the spongy, open-cell foam insulation is less dense. Open-cell foam insulation spray is cheaper but more likely to absorb water, and has a lower R-value and is less suitable in high moisture areas like basements. Open and closed cell foam spray insulation comes in a variety of chemistries including: Cementitious, Phenolic, Polyisocyanurate (polyiso), Polyurethane Icynene and Tripolymer, each conferring unique properties.
At HCP we prefer to opt for the greenest solutions wherever possible and think the best guidance is to use spray foam strategically and sparingly. Spray insulation is very versatile and can be used in a host of locations. From enclosed existing walls, open new wall cavities, unfinished attic floors and even existing finished areas. Closed-cell spray also has a very high R-value. There are however more cost-effective, safer and greener solutions to insulate many of those locations without the risks of toxicity and off-gassing. We advise limiting the use of foam to hard-to-reach and obstructed areas and limited localized sealing application.
Spray insulation expands to fill even the smallest surrounding cavities, creating an effective air barrier. It is ideally suited to fill irregularly shaped areas, and filling gaps around obstructions. These properties make spray foam insulation very efficient at reducing air leakage in holes and cracks, especially around electrical and plumbing penetrations.
Open-cell spray foam insulation has an R-value between R-3.5 to R-3.6 per inch. In other words, filling a 2×4 cavity yields about an R-13. Closed-cell spray foam has a far better R-value at about R-6.5-7 per inch.
During installation, a two-component mixture is sprayed into wall cavities or blown into holes drilled into a finished wall. The foam expands and fills the cavity, providing insulation and air sealing. Slow-curing liquid foams are also available for empty wall cavities. The mixture hardens and cures, dissipating any volatile compounds. The cost of spray foam insulation varies based on the type, composition, and installation methods required.
Spray foam insulation creates an airtight seal, effectively blocking air movement through gaps and cracks in the building envelope. This prevents convective heat transfer and reduces energy loss, making it a highly effective air sealing solution.
