Where to Use Open-cell Spray Foam Insulation
North Carolina open-cell spray foam insulation is a fantastic choice for interior walls, unfinished attics, and floors. This versatile insulation material offers several benefits, making it the perfect solution for these areas in homes and commercial buildings.
The excellent sound-dampening properties of open-cell spray foam make it ideal for use in home interior walls. It can help reduce noise transfer between rooms, creating a quieter, more comfortable indoor environment. That’s especially important if you have a home office or family members who are light sleepers.
Open-cell spray foam insulation is also great for unfinished attics. Attics can be difficult to insulate due to hard-to-reach areas and plenty of gaps that need filling. When sprayed on the attic floor, expands to fill these gaps, creating a complete thermal barrier that can help reduce energy costs.
Homeowners can also use spray foam to insulate floors. Because it conforms to any shape or space, it can easily fill in gaps and tight spaces under floors. It’s also an excellent way to reduce noise transmission between floors, making it a great choice for multi-story homes and apartments.

Open-cell vs. Closed-cell Spray Foam Insulation
Open-cell and closed-cell spray foam insulation are two polyurethane foam insulation types. Their differences make them suited to different applications in homes and commercial buildings. Below are the qualities that differentiate these types of spray foam insulation:
Closed-cell spray foam insulation is an effective vapor barrier, while open-cell spray foam insulation is semi-permeable, allowing some moisture to infiltrate.
Open-cell spray foam insulation is better at reducing noise than closed-cell spray foam insulation, hence its preference for interior walls.
Closed-cell foam has a higher density, making it more rigid and durable. Open-cell spray foam is less dense, softer, and more flexible.
Closed-cell spray foam insulation has a higher R-value (6.5) per inch than open-cell spray foam insulation in North Carolina (3.7). That means closed-cell spray foam has better insulation performance than open-cell spray foam.
Closed-cell spray foam insulation is typically more expensive than open-cell spray foam insulation in North Carolina. The cost per inch of closed-cell spray foam insulation can be up to three times that of open-cell spray foam insulation.

Both types of spray foam insulation have their unique benefits and drawbacks. Closed-cell spray foam is best suited for areas exposed to moisture or high humidity levels, such as crawl spaces or basements. Open-cell spray foam is great for interior walls and attics where moisture is less of a concern and sound dampening is important.

Our North Carolina Open-cell Spray Foam Insulation Installation Process
At All American Spray Foam, we adhere to a tried-and-tested insulation installation process to ensure the insulation works effectively and lasts long. Our installation process involves the following steps:
We start the process by assessing the building and areas that will be insulated and doing the necessary preparations before the installation. That may include clearing obstructions, repairing damage, and sealing air leaks. We also take measurements to estimate the amount of insulation needed.
After applying finishing touches, our experts inspect foam thickness, ensure required specifications, and clean the work area, leaving it debris-free.
After preparation and putting all safety measures in place, our applicators begin applying the open-cell spray foam. They use specialized spray guns that apply the foam in a controlled and precise manner. Our North Carolina open-cell spray foam insulation experts apply the foam to the desired thickness based on the insulation requirements.
Before we begin the installation, our professional spray foam applicators take the necessary measures to protect any exposed areas or surfaces from the spray foam. That could involve covering windows, doors, and other openings. They will also wear appropriate safety gear, such as respirators, gloves, and protective clothing, to protect themselves from the insulation material.
We also advise the building occupants about re-entry guidelines to ensure their safety. Moreover, we ensure that all working areas are sealed off and ventilated to reduce airborne vapor and mist levels generated during the process.
After foam application, our applicators allow 12-24 hours for the foam to harden and cure before trimming and shaping. If the foam doesn’t feel tacky, they trim or cut it to fit around pipes, ducts, or other obstructions. They could also shave it down to correct the unsightly appearance after curing.
