Spray foam insulation is one of the most effective ways to improve comfort, efficiency, and long-term performance in a building. Unlike traditional insulation, spray foam expands to seal gaps, cracks, and hard-to-reach areas, creating a tighter, more controlled indoor environment.
Why Choose Spray Foam?
The Ultimate Insulation
With spray foam insulation, you get a range of added benefits that are difficult, if not impossible, to achieve with traditional insulation options. Explore some of these benefits below:
Spray foam attic insulation seals air leaks at the roofline and attic floor, helping keep your home warmer in winter and cooler in summer. By expanding to fill gaps and penetrations, it reduces drafts, improves energy efficiency, and supports consistent indoor temperatures year-round.
Wall Insulation
Spray foam wall insulation fills wall cavities completely, blocking air movement that can lead to drafts and uneven temperatures. It helps improve comfort, increase energy efficiency, and create a more controlled indoor environment without settling or breaking down over time.
Crawl Space Encapsulation
We provide spray foam encapsulation to fully seal your crawl space. First, we lay a plastic vapor barrier on the floor, then spray foam the walls down to the plastic for a complete seal. This reduces drafts, humidity, and energy loss, creating a healthier, more efficient home.
Open-Cell vs. Closed-Cell Spray Foam
Not all spray foam is the same. Kokomo Spray Foam offers both open-cell and closed-cell spray foam, allowing us to recommend the right solution for your building, your goals, and your budget. In some cases, we even use a combination of both to get the best performance possible.
Closed Cell Spray Foam
Maximum strength, moisture control, and efficiency
Closed-cell spray foam is a dense, rigid insulation that delivers high performance in a thinner application. It’s ideal for areas where strength, moisture resistance, and air sealing matter most.
R-value of approximately 7.2 per inch
Creates its own vapor barrier at 2 inches
Adds up to 300% structural strength to framed assemblies
Dense, rigid foam that resists moisture intrusion
Excellent air sealing to block drafts and outside air
Ideal for crawl spaces, rim joists, metal buildings, and exterior walls
Closed-cell spray foam is often used as the first layer when moisture control or vapor protection is required.
Open Cell Spray Foam
Efficient coverage and consistent comfort
Open-cell spray foam is lighter and expands more than closed-cell, making it well-suited for filling wall and ceiling cavities completely. It’s an effective option for improving comfort and energy efficiency.
R-value of approximately 3.7 per inch
Expands to fully fill wall and ceiling cavities
Seals gaps and cracks to reduce air leakage
Improves indoor comfort and temperature consistency
Helpful for sound control in walls and ceilings
Cost-effective option for achieving higher overall R-values
Open-cell spray foam is commonly used in interior walls or installed over closed-cell insulation, which acts as a vapor barrier, to add R-value in a cost-effective way.
