What is Crawl Space Insulation?

Crawl space insulation, installed under your home, regulates temperature and controls moisture by preventing heat loss, supporting your HVAC system, reducing moisture, mold, and warding off pests.

Matvey Foundation Repair’s ExTremeBloc™ was designed with these benefits in mind. Created to withstand damp crawl space conditions, these insulation panels work best with our all-encompassing encapsulation solutions that seal the crawl space, promoting a healthier home.

Signs You Need Crawl Space Insulation

Recognizing signs of crawl space insulation failure is vital. Yet, entering the crawl space can pose risks and should be done by a certified Matvey Foundation Repair inspector with proper safety equipment.

Here are some major signs of potential issues and items our inspectors check in your crawl space:

Is Crawl Space Insulation Necessary?

Insulating your crawl space is essential for your home’s health, safety, and comfort. However, DIY insulation using products from big-box stores may not solve the actual issues.

Matvey Foundation Repair professionals can provide a precise assessment, repair, and protection for your crawl space. Early action is a key part of our comprehensive solution to maintain your home’s structure and your family’s health.

Common Types of Crawl Space Insulation

Crawl space insulation comes in many forms, including three common types:

  • Fiberglass: Commonly used in homes, but not the best for crawl spaces. It’s usually placed between floor joists and is vulnerable to moisture, mold, and pests.
  • Spray Foam: Used on surfaces such as walls and joists, but not suitable for crawl spaces. Most spray insulation types are closed-cell foams, these are strong but can harbor mold, chemical smells, and termite damage in wet areas.
  • Foam Board: The most effective crawl space insulation type is thermal foam board insulation, like ExTremeBloc™. These panels are custom-fit and installed on the interior crawl space walls. ExTremeBloc™ offers improved heat retention through reflective surfaces and a superior insulation value compared to alternatives.

What Are the Benefits of Crawl Space Insulation?

A vapor barrier is a key part of the crawl space encapsulation system but it’s only one part of the whole encapsulation system. Here’s an overview of the encapsulation process and why a vapor barrier is necessary:

Insulation usually lasts 15-20 years but can wear out sooner if the crawl space is damp. Our ExTremeBloc™ foam is a long-lasting solution. For more details, contact us for a free checkup.
