Spray Foam vs. Fiberglass Insulation
When it comes to insulating your home, the choice between fiberglass and spray foam insulation is critical. At The Attic Experts, we’ve witnessed the advantages and potential drawbacks of both materials. While spray foam insulation has become popular, recent reports suggest that fiberglass insulation is a safer and more reliable option.
Recent Concerns with Spray Foam Insulation
Recent news has highlighted concerns regarding spray foam insulation, specifically its potential to impact homeowners’ insurance and mortgage eligibility. Some insurance and mortgage companies are refusing to insure homes with spray foam insulation due to several issues:
Trapped Moisture and Rot: Spray foam insulation creates an airtight seal that can trap moisture within your home’s structure. This can lead to mold growth and wood rot, which are often hidden and costly to repair. The International Association of Certified Home Inspectors (InterNACHI) warns that improper installation of spray foam can exacerbate these problems.
Off-Gassing and Health Concerns:
Spray foam insulation contains chemicals that can release volatile organic compounds (VOCs) during and after installation, a process known as off-gassing. These emissions can negatively affect indoor air quality and potentially cause respiratory issues, as noted by the Environmental Protection Agency (EPA).
Complications in Home Inspections and Sales: Spray foam can complicate home inspections because it can cover structural elements, making it difficult to assess potential issues. Additionally, improper installation may require costly removal and replacement, which can be a red flag for mortgage lenders.
Hiding Termite and Insect Activity:
One of the lesser-known but significant concerns with spray foam insulation is its potential to hide termite and other insect activity. Because spray foam adheres tightly to surfaces and fills gaps, it can conceal signs of termite damage or other destructive insect infestations. This can make it difficult for homeowners and inspectors to detect these issues early, potentially leading to serious structural damage over time.
Challenges with Attic Ventilation:
Proper attic ventilation is crucial for maintaining the health of your home. Traditional attic insulation systems rely on good ventilation to prevent moisture buildup and to regulate temperatures. However, spray foam insulation creates a sealed environment that can disrupt the natural ventilation process. Without adequate ventilation, heat and moisture can become trapped in the attic, leading to issues like mold growth, reduced roof lifespan, and compromised indoor air quality. Homeowners may need to install additional mechanical ventilation systems, adding to the overall cost and complexity of maintaining a healthy attic environment.
The Advantages of Fiberglass Insulation
Fiberglass insulation, particularly Owens Corning Fiberglass, provides a safer and more dependable alternative. Here’s why fiberglass insulation is often the better choice:
Proven Performance:
Fiberglass insulation has been trusted for decades to reduce energy consumption, maintain consistent indoor temperatures, and provide excellent soundproofing. The North American Insulation Manufacturers Association (NAIMA) supports fiberglass as a reliable insulation material due to its long-standing track record.
No Off-Gassing:
Unlike spray foam, fiberglass insulation is made from recycled glass and sand, and does not emit harmful VOCs. This makes it a safer option for maintaining good indoor air quality, as confirmed by the American Lung Association.
Cost-Effective and Easy to Install:
Fiberglass insulation is generally more affordable and less disruptive to install compared to spray foam. According to HomeAdvisor, fiberglass installation is simpler and more cost-effective, making it a practical choice for many homeowners.
with Home Inspections and Sales:
Homes insulated with fiberglass typically pass inspections without issues. Since fiberglass does not trap moisture or obscure structural components, it’s easier for inspectors to assess the condition of the home, which can be reassuring for both buyers and lenders.
Choose Fiberglass for a Safer, Smarter Insulation Solution
While spray foam insulation might seem like a modern solution, its potential pitfalls cannot be overlooked. Fiberglass insulation, particularly Owens Corning Fiberglass, offers a proven alternative that avoids the risks associated with spray foam. With fewer health concerns, easier inspections, better ventilation compatibility, and a reputation for reliable performance, fiberglass insulation is the smart choice for homeowners in suburban Chicago and beyond.
