Why Use Spray Foam Insulation? Pros, Cons & Core Considerations
Spray foam has become a popular choice for homeowners and business owners alike. Its ability to enhance energy efficiency, improve indoor comfort, and increase structural integrity makes it a standout among insulation options.
However, like any product, it has its pros and cons. Let’s explore the pros and cons of spray foam insulation, and special considerations to help you determine if it’s the right fit for your space.
What is spray foam insulation?
Spray foam insulation is a versatile material made from polyurethane or similar substances. Applied as a liquid, it expands into a foam that fills gaps, cracks, and crevices, providing a seamless barrier against heat transfer, air leakage, and moisture. There are two main types: open-cell and closed-cell foam, each suited for specific applications and offering unique advantages.
What are the advantages of spray foam insulation? 9 reasons to choose it
1. Superior energy efficiency
Spray foam insulation provides an unmatched thermal barrier, significantly reducing energy costs. With a high R-value compared to traditional materials, it’s particularly effective in Vermont and New Hampshire's colder climates, keeping your home warm in winter and cool in summer.
2. Improved indoor air quality
By sealing gaps and preventing drafts, spray foam insulation reduces the infiltration of allergens, pollutants, and outdoor air, contributing to a healthier indoor environment.
3. Moisture and mold resistance
Spray foam acts as a barrier against moisture, making it less susceptible to mold growth. Closed-cell foam, in particular, is water-resistant, making it ideal for basements and crawl spaces.
4. Enhanced Structural Strength
Closed-cell spray foam adds rigidity to walls, ceilings, and roofs, increasing the structural integrity of your property. This can be particularly beneficial in areas prone to heavy snow or wind.
5. Long-term cost savings
While the upfront cost of spray foam may be higher, its durability and energy-saving properties lead to significant savings over time.
6. Noise reduction
The sound-dampening properties of spray foam make it a great choice for homes near busy roads or noisy neighbors.
7. Eco-friendly and sustainable option
Many spray foam products are made with environmentally friendly materials and help reduce your carbon footprint by improving energy efficiency.
8. Versatility and ease of application
Spray foam adheres to various surfaces and can be applied in hard-to-reach areas, making it suitable for a range of building types and designs.
9. Increased property value
Homes with spray foam insulation often attract higher resale values due to improved energy performance and comfort.
What are the negatives of spray foam insulation?
While spray foam insulation offers many benefits, it’s not without drawbacks.
Professional installation required: DIY installation requires specialized tools and expertise.
Environmental Impact: Made with chemicals that may have a higher environmental footprint than cellulose insulation.
Limited Applications: May not be the best choice for open attic spaces, where cellulose often provides more uniform coverage.
Removal Challenges: Unlike cellulose, spray foam can be harder to remove or adjust once applied.
