How and When To Add Spray Foam Insulation

Spray foam insulation is a high-performance and long-lasting type of insulation that offers superior protection for your home. Known for its insulative and air sealing properties, spray foam can improve energy efficiency and enhance indoor comfort. Its numerous benefits and durable nature make it a popular choice for homeowners and builders throughout Vermont and Western New Hampshire. However, while spray foam can last for decades, its permanence also means that proper application is crucial. 

As spray foam experts serving the area since 2006, Vermont Foam Insulation provides award-winning, whole-home insulation services. Our team regularly undergoes extensive training to keep up with current best practices and we’ve built a reputation for outstanding service in both new construction and existing homes.

The Spray Foam Application Process

At VFI, we follow a strict protocol when installing spray foam insulation because it is a delicate process that requires training, experience, and attention to detail. DIY spray foam installations are not recommended due to the complexities involved and the potential safety risks. Our trained professionals use industry-standard equipment and techniques to ensure a safe and effective installation.

  1. Preparation: We begin with removing any boxes or furniture, thoroughly cleaning all surfaces, and old insulation removal if necessary.
  2. Application: Our spray foam technicians will create the liquid mixture of chemicals that initiate the foaming process and apply it using specialized equipment. The foam expands rapidly upon application, filling every nook and cranny, and creating an airtight barrier.
  3. Curing: Once applied, the foam cures and forms a rigid, durable insulation layer. The exact curing time depends on a few factors, like the extent of insulation and specific type, but the building will need to be vacant for at least 24 hours after installation for optimal safety
  4. Final Testing: After installation is complete, the VFI team will test its performance to ensure all air gaps are effectively sealed and the desired level of insulation is reached. 

Spray Foam for New Construction Homes

New construction projects present the ideal scenario for installing spray foam insulation. When building a new home or addition, you have the opportunity to incorporate spray foam into the walls, ceilings, and floors from the outset, maximizing its effectiveness and setting yourself up for success with year-round energy efficiency.

Spray Foam for Retrofit Insulation Upgrades

While spray foam is an excellent choice for new construction, its application in retrofit upgrades requires careful consideration. We most often install spray foam in existing attics, basements, or crawl spaces because it can easily be applied in these areas, and it will have an impact on your whole home’s performance. 

Installing spray foam in existing walls can be challenging due to the limited space available for insulation. This can reduce the effectiveness of the insulation if installed properly. One unique advantage of using injection foam is its exothermic reaction during expansion, which generates significant heat. This allows us to monitor its progress within the wall cavity with an infrared camera, providing real-time visibility of the foam’s placement and ensuring no gaps are left behind. Unlike cellulose insulation, injection foam’s heat profile helps us confirm a thorough and consistent application in hard-to-reach areas, enhancing the insulation’s effectiveness.

Additional Benefits of Properly Installed Spray Foam

Spray foam insulation offers powerful moisture control benefits, which can significantly enhance home comfort and durability. For example, when applied to older basement foundation walls, spray foam helps reduce relative humidity in the basement, positively affecting moisture levels throughout the entire house. This insulation solution also addresses the challenges of attic ventilation. By encapsulating the entire attic roof plane, spray foam creates a more energy-efficient environment, often reducing roof snow melt during winter.

Beyond moisture control, spray foam insulation protects against issues like freezing pipes, especially in older homes with heating system components located in colder basements or attics. Encapsulating these areas with spray foam brings these mechanical elements into the “conditioned” part of the home, improving the distribution efficiency of heating systems—particularly forced hot air systems.

With spray foam insulation, homeowners can experience a transformative improvement in energy efficiency, comfort, and home durability. Benefits include lower energy bills, warmer floors, dryer basements, and attics free from condensation issues—all thanks to the versatility and performance of spray foam insulation.
