Crawl Space Insulation Types: Best & Worst
Crawl space insulation is essential for maintaining a healthy, energy-efficient home. Proper insulation helps regulate your home’s temperature, reduces energy bills, and prevents moisture and mold issues.
However, choosing the right type of insulation for your crawl space is crucial. The wrong choice can lead to significant problems, undermining the benefits you’re aiming to achieve.
On this page, you’ll learn about the best and worst types of crawl space insulation to ensure you make the right choice for your home.
The Worst Types of Crawl Space Insulation
Selecting the wrong insulation for your crawl space can do more harm than good.
Two of the most common yet problematic types are fiberglass insulation and spray foam.
- Fiberglass Insulation: While common, fiberglass absorbs water, creating an ideal environment for mold growth. Once wet, its insulating properties are compromised, and it becomes a breeding ground for mold, negatively impacting indoor air quality.
- Spray Foam: This option might seem appealing due to its initial insulating properties, but it has several downsides. Spray foam can emit a chemical smell and, like fiberglass, can harbor mold. Additionally, it can attract termites, leading to structural damage over time.
The Best Crawl Space Insulation: Rigid Foam Board
For optimal crawl space insulation, a rigid foam board is a superior choice.
Groundworks installs ExTremeBloc™, a thermal foam board featuring reflective surface panels for enhanced heat retention and insulation value.
These panels are precisely cut to fit your crawl space walls and come with a Class A safety rating.
ExTremeBloc™ ensures your crawl space remains dry and well-insulated, providing long-lasting benefits.
Benefits of Quality Crawl Space Insulation
Investing in high-quality crawl space insulation offers numerous advantages, including:
- Moisture Control: Proper insulation helps manage moisture levels, preventing dampness and protecting your home’s structure.
- Mold Prevention: Controlling moisture significantly reduces the risk of mold growth, which can negatively affect your health and home.
