A Superior
Thermal & Air Barrier Services in Durham
Spray foam insulation offers a range of advantages for property owners in Durham, making it a favored option for both homes and businesses. This innovative insulation method effectively minimizes heat transfer, which contributes to improved energy efficiency when compared to conventional insulation materials. Its distinct benefits make it well-suited for various architectural styles throughout the region.
These capabilities define the insulation type:
Blocks Air Infiltration: The insulation system prevents treated air from transferring through gaps, holes, or damage in exterior walls and roofs.
Stops Moisture: Spray foam blocks moisture from entering the treated space and contributing to heat loss or gain.
Advantages Of
Spray Foam Insulation in Durham
Spray foam insulation outperforms all other types of insulation by large margins because its long-term benefits outweigh its initial installation costs. Spray foam also offers superior sealing properties and is environmentally friendly.
Improved Air Quality
Proper insulation plays a crucial role in protecting your residence from dust, allergens, and various undesirable particles. Choosing spray foam insulation can greatly improve your indoor air quality by effectively sealing cracks and controlling moisture. This method not only creates a healthier living space for your family but also boosts the overall energy efficiency of your home.
Water & Fire Resistance
Spray foam insulation is an outstanding option for protecting your home from moisture while enhancing fire safety. This insulation method forms a robust barrier that minimizes the risk of mold growth and prevents water-related damage. Moreover, it promotes a healthier living space by improving safety and comfort, making your home more welcoming and significantly elevating your overall quality of life.
Pest and Wildlife Protection
Spray foam insulation acts as a robust defense against unwanted pests like rodents and insects that may try to enter your home. This advanced insulation option forms a seamless protective layer that significantly enhances your home’s energy efficiency, fostering a more comfortable and secure atmosphere for your family. Choosing spray foam insulation is a smart decision that fortifies your home against pest infestations, creating a peaceful and safe haven for your loved ones.
Strengthens Buildings
Spray foam insulation is essential for establishing a well-insulated and energy-efficient home. When applied properly and given time to cure, it creates a robust bond with critical elements like framing, sheathing, and interior surfaces. This strong attachment not only improves the structural integrity of the building but also adapts to natural movements and settling over time. Additionally, it reduces vibrations within the walls and enhances sound insulation, resulting in a quieter living environment. These benefits are important for ensuring both the longevity and energy efficiency of your home.
Soundproofing
Enhancing the comfort of your living space has become easier thanks to the newest innovations in foam insulation technology. This cutting-edge material adeptly infiltrates and seals any crevices and flaws in your walls, ceilings, and floors, creating a robust barrier that significantly reduces drafts. Additionally, foam insulation excels at minimizing noise levels due to its thick structure, which blocks sound from traveling. Consequently, you will notice a significant decrease in both outside noises and interruptions from HVAC systems. This improvement creates a more peaceful and welcoming environment in your home.
Environmentally Friendly
Investing in spray foam insulation is a proactive step toward a more energy-efficient, resilient home in Durham. Unlike traditional materials that may shed fibers, cured spray foam is chemically inert, meaning it does not release harmful particles into your living space. During the professional installation process, specialized equipment ensures a precise application tailored to the specific climate needs of Durham properties. While a brief off-gassing period is standard, once cured, the foam provides a permanent, seamless air seal. Because spray foam, particularly closed-cell varieties, does not retain moisture or support mold growth, it acts as a robust secondary barrier against water damage, preserving your home’s structural integrity for decades.

Should I insulate my basement ceiling with spray foam?
Closed-cell spray foam works best for basement ceilings because it provides a high R-value and acts as a moisture barrier. It can also help block sound between floors. For the best results, it’s important to assess your home’s layout, HVAC design, and moisture conditions before choosing where to apply spray foam.
Koala Insulation technicians can evaluate your space and recommend whether ceiling, wall, or rim-joist insulation will deliver the greatest comfort and energy savings for your home.
Is spray foam insulation safe?
Spray foam insulation is safe when handled and installed by a trained professional. Spray foam poses no health risk once it is cured, but it can be hazardous during installation due to its chemical composition. We follow all industry safety standards, ensure proper ventilation, and complete curing before occupants return to the space, usually 24-48 hours after project completion.

Can you insulate the concrete block walls in my basement?
Concrete block basement walls can be insulated with spray foam, provided the surface is clean, dry, and free of moisture issues. Closed-cell spray foam is typically best, as it both insulates and creates a moisture-resistant air seal that helps prevent mold and drafts. Before application, any existing leaks or dampness should be addressed to ensure long-term performance and adhesion.
At Koala Insulation, we’ll determine whether spray foam, rigid foam board, or a hybrid system is the best fit for your block-wall basement so you get a solution built for long-term performance.
Do My Rim Joists Need An Airtight Seal?
Rim joists absolutely benefit from an airtight seal. Sealing this area with spray foam insulation prevents drafts, moisture intrusion, and heat loss where the foundation meets the framing, one of the most common sources of energy waste in a home. By creating a continuous air barrier, you’ll enjoy warmer floors, lower utility bills, and better indoor air quality year-round.

Is spray foam insulation flammable?
Spray foam insulation itself is not flammable once fully cured, but like most building materials, it can burn when exposed to direct flame. Koala Insulation uses fire-rated, code-compliant products. When installed correctly by our certified technicians, spray foam insulation provides a safe, durable, and energy-efficient layer that meets modern fire safety standards.

When installed correctly by our certified technicians, spray foam insulation provides a safe, durable, and energy-efficient layer that meets modern fire safety standards.
How long does spray foam insulation last?
Spray foam insulation typically lasts 80 to 100 years when professionally installed and properly maintained. Spray foam adheres directly to the building structure and won’t sag or settle, which means it offers the same performance decade after decade.
What are the best applications for spray foam insulation?
Spray foam insulation is a premium, versatile option for a few specific applications. After your initial assessment, we may recommend spray foam for:
Attics: Open-cell spray foam on attic floors seals air leaks and prevents treated air in the living space from escaping into the attic.
Basements: Closed-cell spray foam acts as a vapor barrier in moisture-prone basements, crawl spaces, and cellars.
Exterior Walls: While not always necessarily the most cost-effective option, spray foam fills irregular gaps in wall cavities while providing an effective moisture barrier.
Floors: Spray foam is sometimes sprayed between floor joists in suspended timber floors (non-slab).
Roofs: Closed-cell spray foam installed under the roof deck prevents air leaks and protects against moisture issues.
Can I spray foam insulation myself?
While DIY kits exist, spray foam insulation is not a good do-it-yourself project. Professional installers have the training, equipment, and ventilation controls needed to ensure safety, proper curing, and compliance with building codes. Poor installation from DIY attempts can lead to moisture problems, off-ratio foam, or even voided home insurance coverage, making professional service from Koala Insulation technicians the smarter, safer choice.
