Crawl Space Insulation

Dealing with cold floors, drafty rooms, and rising energy expenses are typical signs of damage insulation in your crawl space. Often, a crawl space doesn’t have the right type of insulation, but we can help. 

AFS offers a leading solution called ExTremeBloc™ Crawl Space Insulation. As the leading crawl space experts in the Southeast United States, we specialize in crawl space encapsulation with a wide array of tools at our disposal. Read on to learn how our expertise improves your home’s comfort and durability! 

What is Crawl Space Insulation? 

Crawl space insulation is a material applied to the underside of your home. 

It plays a vital role in overall home energy efficiency and indoor air quality. Insulating the crawl space adds a layer of protection against heat loss and creates a barrier against moisture, reducing mold and deterring pests. 

Effective crawl space insulation, like ExTremeBloc™, is designed to endure the humid conditions typical under homes. 

Combining insulation with crawl space encapsulation—sealing the area from external air and ground—results in controlled humidity, lower energy costs, and enhanced air quality. 

At AFS, we view crawl space repair as integral to your home’s overall health, contributing to a more enjoyable living environment and safeguarding your home’s structural integrity. 

Signs You Need Crawl Space Insulation 

Identifying the need for crawl space insulation early can prevent expensive repairs in the future and keep your home safe. Here’s what you should look out for: 

These signs indicate moisture issues that can lead to severe damage if ignored. It’s crucial to arrange a free inspection with crawl space experts when you notice any of these symptoms. 

Is Crawl Space Insulation Necessary? 

Yes, insulating your crawl space is vital for protecting your home. 

Neglecting insulation issues allows moisture and humidity to increase, fostering mold growth that can aggravate health issues. Pests and rodents can also enter through uninsulated gaps. 

At AFS, we stress early action as part of our comprehensive home care approach, ensuring your home’s structural longevity and its occupants’ well-being. 

We advise against DIY methods, as most store-bought solutions often don’t solve the core problem. It’s better to work with a crawl space professional, like AFS, for accurate assessment, repair, and protection of your crawl space. 

What Are the Different Kinds of Crawl Space Insulation? 

Various types of insulation are used in crawl spaces. It’s important to get a professional inspection so you can know the details about your insulation. Here are the most common used in crawl spaces all over the Southeast United States: 

Fiberglass Insulation 

Fiberglass is a common insulation choice in homes nationwide, but it’s not ideal for crawl spaces. Typically, this soft material is installed between floor and rim joists in the crawl space to regulate the temperature of the floor above. However, it’s prone to moisture, mold, and pests. 

Spray Foam Insulation 

This insulation is applied directly to surfaces like crawl space walls and joists to block extreme temperatures. Yet, it’s not the best choice for crawl spaces. 

Mostly, it’s closed-cell spray foam, which is more robust but not impervious to damage. In a moist crawl space, spray foam can harbor mold, emit chemical smells, and attract termites. 

Foam Board Insulation 

For superior crawl space insulation, consider large, pre-cut sheets of thermal foam board insulation like ExTremeBloc™. These panels are tailored to fit and installed on interior crawl space walls and feature reflective surfaces for better heat retention. 

What Are the Benefits of Crawl Space Insulation? 

When your crawl space insulation is installed by AFS, it offers a few major advantages: 

  • Moisture Control: It prevents moisture intrusion, reducing mold, pests, and ground moisture issues that can compromise your home’s health and safety. 
  • Energy Efficiency and Cost Savings: Inadequate insulation forces your heating and cooling systems to work harder, spiking energy costs. Insulation blocks hot and cold external air, saving you money in the long run. 
  • Improved Indoor Comfort: Insulation panels create a more comfortable home by stabilizing floor temperatures and contributing to better air quality, promoting a healthier living space. 

Using our specialized solutions and professional services is crucial for the best results. Our products, designed with cutting-edge technology and top-quality materials, surpass standard options, offering unmatched benefits for your home.
