Open Cell Spray Foam Insulation: Pros and Cons, Best Areas To Apply It, And More

Spray foam insulation is a great way to insulate your home. It outperforms other types of insulation and does not require the use of spray foam installation professionals, which can save you money in the long run. There are two types of spray foams: open-cell spray foam and closed-cell spray foam. This article will discuss open-cell spray foam insulation, its pros and cons, the best areas to apply it, and more!

Open Cell Spray Foam Insulation: What Is It?

Open-cell spray foam insulation is a type of spray foam that has many benefits, including air sealing, moisture and mold resistance, and durability. It also outperforms competitors in R-value, damage, and versatility. Open-cell spray foam can be manufactured at the site or delivered to the site in pre-manufactured form.

It has an R-value of around 4 per inch, which is nearly double that of competing spray foam insulation products.

Open Cell Spray Foam Insulation: Pros and Cons

The Pros

The pros to open-cell spray foam are many; it outperforms other spray foams with its R-value, there’s a varied range of colors available so you can match your house better if desired, and spray foam can be applied to uneven surfaces. It’s also much easier to maintain than closed cell spray foams, making it a more practical choice for homeowners looking for low-maintenance options.

Spray foam insulation is a higher-ranking choice for many homes in the US. It can be applied to new and old homes, making it one of the best choices for homeowners who want to play their part in conserving energy by insulating their homes with spray foam. Spray foam offers some fantastic benefits such as R-Value (a measure of thermal resistance), moisture, air sealing, and mold damage.

The Cons

The cons of open-cell spray insulation are that there could be some air bubbles in the insulation, which will take time to go away on its own, it is more expensive than other types of insulation, and there are more restrictions on what you can do with spray insulation since open-cell spray foams require a surface that’s been prepped before application.

It also requires professional installation in some areas because it is challenging to work with spray foam without proper experience and training. Spray foam can be expensive due to its benefits; it can be five times more expensive than other insulation types.

Open Cell Spray Foam: Best Areas to Apply It

The best areas to apply open-cell spray foam would be your attic, basement, or around windows and doors. You want to spray the insulation on a surface that is in good shape with no holes, tears, or water damage.

Application Process Of Open Cell Spray Foam Insulation

The spray foam insulation is applied to the inside of a building. The spray equipment, which releases one or more streams of pressures from two to five pounds per square inch (psi), can be maneuvered around corners and onto vertical surfaces with minimal loss during application, so it’s airtight.

The spray foam insulation consistency will vary depending on the application. Open-cell spray foam is commonly applied at a thickness of up to three inches (75 mm). The sprayer nozzle is turned off when spray pressure drops below 15 psi, and the gun tip has reached the end of its motion, but most open-cell sprayers leave their nozzles on until they are against something solid like a wall.

Price Of Open Cell Spray Foam Insulation

The spray foam insulation price is determined by the type of sprayer and the number of square footage. If you have a large project, then it would be best to hire an expert who’ll come in with all their own equipment. This way, you can take your time doing other things around the house while they spray away for hours!
