Discover the answers you might be seeking on our customer-friendly Armour Spray Foam FAQ page. We have put together this comprehensive resource to provide you with the information and most asked questions from our great customer base over the years. Whether you’re curious about the benefits of our services, the installation process, or the cost-effectiveness of spray foam insulation, our FAQs have got you covered.

Spray foam insulation is a type of insulation material that is applied as a liquid and expands into a foam. It is typically made of two components, polyol resin, and isocyanate, which react when mixed and create an expanding foam. The foam fills gaps, crevices, and cavities, providing an airtight and thermal barrier.

Spray foam insulation offers several benefits, including improved energy efficiency, reduced air leakage, enhanced indoor comfort, noise reduction, and moisture control. It can also help prevent the entry of pests and allergens into your home.

The cost of spray foam insulation varies depending on factors such as the size of the area to be insulated and the region. While the initial cost may be higher than other insulation options, many homeowners find it worth the investment due to its long-term energy savings and benefits.

Spray foam insulation is suitable for most types of homes and buildings, including new constructions, existing structures, and various architectural styles. It can be used in attics, walls, basements, crawl spaces, and other areas where insulation is needed.

Spray foam insulation is known for its durability and longevity. When properly installed, it can last for several decades without significant degradation. It generally does not require maintenance, but periodic inspections are recommended to ensure its effectiveness.

During installation, proper precautions should be taken, including wearing protective gear and ensuring proper ventilation. Once the foam cures, it is generally considered safe. However, it is advisable to consult with professionals to address any specific concerns or sensitivities.

Spray foam insulation provides superior air sealing properties compared to traditional insulation materials like fiberglass or cellulose. It has a higher R-value per inch, meaning it offers better thermal resistance and can provide greater energy efficiency.

Yes, spray foam insulation is known for its excellent insulation properties, which can significantly reduce air leakage and heat transfer. By creating an effective thermal barrier, it helps to stabilize indoor temperatures, reducing the load on heating and cooling systems and potentially lowering energy bills.

The installation process involves a trained professional who sprays the foam onto the designated areas. The foam expands and hardens within a short time, forming an insulating layer. The process typically requires appropriate surface preparation, precise mixing of the components, and skilled application techniques.

Yes, spray foam insulation has sound-dampening properties and can help reduce noise transmission. By sealing gaps and creating a solid barrier, it minimizes airborne sound transfer, improving acoustic comfort within your home.


It’s important to note that while these answers provide a general understanding of spray foam insulation, it’s always recommended to consult with professionals who specialize in spray foam services for specific advice.

The required R-value for your spray foam insulation project depends on factors such as your climate zone, local building codes, and your specific insulation goals. It’s recommended to consult with a professional insulation contractor who can assess your needs and provide guidance on the appropriate R-value for your project.

Open-cell and closed-cell spray foam are two types of spray foam insulation with different characteristics. Open-cell foam is lighter and has a lower density, providing excellent sound absorption but lower moisture resistance. Closed-cell foam is denser, offers a higher R-value per inch, and provides a vapor barrier, making it more effective in moisture-prone areas. The choice between the two depends on factors such as the specific application, budget, and insulation requirements. A professional insulation contractor can help determine which type is best suited for your project.

The choice between blow-in insulation and spray foam insulation depends on several factors, including your specific needs, budget, and the area to be insulated.

Blow-in insulation, such as cellulose or fiberglass, is typically less expensive than spray foam and is suitable for attics, wall cavities, and other accessible areas. It is installed by blowing loose-fill insulation into the desired space, providing good thermal resistance. However, it may not offer the same air sealing properties as spray foam.


On the other hand, spray foam insulation provides superior air sealing capabilities and can be applied to various surfaces, including walls, attics, and crawl spaces. It expands to fill gaps and crevices, creating an effective thermal barrier. Spray foam insulation also has a longer lifespan and can provide better energy efficiency. However, it tends to be more expensive upfront.


Ultimately, the better option depends on your specific requirements and budget. It is recommended to consult with insulation professionals who can assess your needs and provide personalized recommendations based on factors such as energy efficiency goals, moisture control, and insulation performance.
