Choosing Wisely: Selecting the Best Insulation for Your Crawl Space
Spencer Turner • October 4, 2023

Welcome to our latest blog post on "Choosing Wisely: Selecting the Best Insulation for Your Crawl Space." When it comes to optimizing your home's energy efficiency, comfort, and overall health, the insulation you choose for your crawl space plays a pivotal role. In this article, we'll guide you through the essential considerations and factors to help you make an informed decision on the best insulation type that aligns with your crawl space's unique needs.



Factors to Consider When Choosing Crawl Space Insulation

Selecting the right insulation for your crawl space is a decision that warrants careful consideration, as it can significantly impact your home's comfort and energy efficiency. One of the primary factors to weigh is the moisture level in your crawl space. If your crawl space tends to be damp, choosing moisture-resistant insulation materials like rigid foam or closed-cell spray foam can help prevent mold and mildew growth while maintaining effective insulation.


Another crucial factor is the presence of pests or critters in your area. If your crawl space is susceptible to infestations, insulation like fiberglass or cellulose might not be the best options, as they can attract rodents and insects. Instead,
opt for materials like foam-based insulations that are less inviting to pests. Additionally, consider the insulation's R-value, which measures its thermal resistance. Crawl spaces located in colder climates may require higher R-value insulation to effectively regulate indoor temperatures. By carefully evaluating these factors and consulting with insulation professionals, you can make an informed choice that leads to a well-insulated and comfortable home.

Types of Insulation for Crawl Spaces: Which Is the Best Fit?

When it comes to insulating your crawl space, a variety of insulation types are available, each with its own strengths and suitability for different scenarios. One common choice is fiberglass insulation, which is cost-effective and widely used. However, it might not be the best fit for crawl spaces prone to moisture, as it can absorb water and lose its effectiveness over time.


If moisture is a concern, rigid foam insulation emerges as a strong contender. This type of insulation is moisture-resistant and durable, making it well-suited for crawl spaces with damp conditions. It also provides an effective thermal barrier that helps regulate indoor temperatures. Another option is spray foam insulation, known for its excellent coverage and ability to seal gaps effectively, creating an airtight barrier. However, professional installation is essential for spray foam insulation to ensure its proper application and ventilation. By understanding the attributes of these insulation types and considering your crawl space's unique characteristics, you can determine which insulation is the best fit to create a more energy-efficient and comfortable home environment.

Expert Tips for Selecting the Best Crawl Space Insulation

Selecting the ideal insulation for your crawl space is a decision that can greatly influence your home's energy efficiency and overall comfort. To help you navigate this process like an expert, consider these valuable tips that will guide you toward choosing the best crawl space insulation for your specific needs.


Firstly, thoroughly assess your crawl space's conditions. Factors such as moisture levels, local climate, and the presence of pests will play a significant role in determining the most suitable insulation type. For moisture-prone crawl spaces, moisture-resistant materials like closed-cell spray foam or rigid foam insulation are recommended. Next, consider the insulation's R-value in relation to your region's climate. Colder climates require higher R-value insulation to effectively combat heat loss. Additionally, consult with insulation professionals to receive personalized recommendations tailored to your home's unique characteristics. By leveraging these expert tips and conducting thorough research, you can confidently choose crawl space insulation that optimizes energy efficiency and ensures year-round comfort.

FAQs

  • What factors should I consider when selecting crawl space insulation?

    Choosing the best insulation for your crawl space involves evaluating factors such as moisture levels, local climate, the presence of pests, and your desired level of energy efficiency. These factors will guide you toward insulation materials that can effectively address the unique conditions of your crawl space.

  • What insulation materials are suitable for crawl spaces prone to moisture?

    Crawl spaces with high moisture levels require insulation materials that are moisture-resistant. Rigid foam insulation and closed-cell spray foam are often recommended in such cases, as they can prevent water absorption and mold growth, ensuring long-term insulation effectiveness.

  • How do I determine the appropriate R-value for my crawl space insulation?

Asbestos was once hailed as a “miracle material” for its heat resistance, durability, and insulating capabilities. For decades, it was widely used in residential construction—especially in insulation, floor tiles, roofing materials, and textured ceilings. However, growing awareness of its severe health risks prompted a series of regulatory crackdowns. So, when was asbestos banned in homes? The answer isn’t straightforward—but knowing the history is essential for homeowners, renovators, and anyone living in a home built before 1990. Asbestos Use in Residential Construction: A Historical Overview Asbestos use in homes peaked between the 1930s and the 1970s. It was commonly found in: Insulation (especially around pipes and ducts) Vinyl (VCT) floor tiles and adhesives (mastic) Roofing shingles and flashing Cement siding (“transite”) Acoustic ceiling tiles Popcorn ceiling texture Joint compounds - like those found in typical drywall Cement products Although concerns about asbestos exposure surfaced as early as the 1960s, it wasn't until the late 1970s and 1980s that its use began to be seriously curtailed - but not eliminated. When Was Asbestos Banned? Contrary to popular belief, asbestos has not been fully banned in the United States. Instead, its use has been heavily restricted through a series of phased regulations: 1973: The EPA banned spray-applied asbestos-containing materials for fireproofing and insulation. 1977: The Consumer Product Safety Commission banned asbestos in wall patching compounds and artificial fireplace embers. 1989: The EPA issued a full ban under the Asbestos Ban and Phase-Out Rule—but it was largely overturned in 1991. Present Day: Many asbestos-containing materials are no longer manufactured or sold, but asbestos remains legal in certain products under strict regulation. Because of this phased and partial ban, asbestos-containing materials can still be found in homes built as late as the 1980s—and even later in some imported materials. How Do I Know If My Home Contains Asbestos? If your home was built before the mid-1980s, there's a high chance it may contain asbestos. However, asbestos is not dangerous unless it is disturbed and becomes airborne. Common risk scenarios include: Renovation or demolition of older homes Damage to aging building material DIY repairs involving insulation or flooring Professional asbestos inspection and testing are the only reliable ways to confirm its presence. Where Can Asbestos Still Be Found in Homes? Even homes built into the 1980s or early 1990s may contain asbestos. It’s often present in: Popcorn/textured ceilings Vinyl tiles and mastic adhesives Duct and pipe insulation Roofing and siding materials Joint compound used in drywall taping What EAS Environmental Can Do to Help At EAS Environmental, our certified professionals specialize in: Asbestos inspections and risk assessments Sample collection and laboratory testing Safe asbestos abatement and removal Post-removal air quality verification We adhere strictly to federal and state guidelines, ensuring that any asbestos-containing materials are handled safely and effectively. Don’t Take the Risk—Test Before You Renovate Whether you’re planning a renovation or simply want peace of mind, understanding your home's asbestos risk is crucial. Ignoring potential exposure can lead to serious health issues like mesothelioma, lung cancer, and asbestosis. Contact EAS Environmental today to schedule a professional inspection and safeguard your property and your health. FAQ – Common Asbestos Questions Q: Is asbestos still used today? A: Yes. Some imported products may legally contain asbestos (e.g., brake pads, roofing, gaskets). Q: Can I test for asbestos myself? A: DIY kits are available but unreliable. Disturbing the material could create a health risk. It is best to consult with a certified professional. Q: What’s the safest way to remove asbestos? A: Consult with licensed abatement specialists who follow EPA and OSHA standards. Q. Can I find asbestos on new homes? A: Yes. Some newer homes may still contain asbestos in imported materials, leftover stock, or legal non-friable products like certain floor tiles or roofing materials. References 1.
