Are cold floors, drafts, and high energy bills familiar in your home? The underlying cause may surprise you: moisture and energy inefficiency caused by inadequate crawl space insulation.

Neglecting these signs can lead to worsening issues, but addressing them with crawl space insulation protects your residence. Without adequate insulation, your home becomes vulnerable to mold growth and pest infestations.

With comprehensive crawl space encapsulation services from AFS Foundation & Waterproofing Specialists, you get a healthier, more energy-efficient home. We are the industry-leading crawl space experts near you, serving Alabama, Tennessee, and Kentucky.

What is Crawl Space Insulation?

Crawl space insulation is a material, ranging from thick, fluffy fiberglass to various foam types, installed in the crawl space, usually between the floor joists or on the walls.

This insulation regulates temperature, influencing energy efficiency and indoor air quality. It is a barrier against heat loss and creates a moisture-resistant crawl space environment.

Our crawl space insulation and other encapsulation solutions, such as vapor barriers, offer stable humidity levels, reduced heating and cooling costs, and enhanced indoor air quality. Crawl space encapsulation is a vital component in holistic home maintenance from AFS.

Signs You Need Crawl Space Insulation 

Identifying the need for crawl space insulation early prevents expensive repairs in the future and ensures a safe home. However, we advise against entering the crawl space area as it can be hazardous.

There are several signs to look for within your home that point to problematic crawl space insulation, including: 

These signs indicate moisture issues that can cause significant damage if ignored. When you notice these symptoms, schedule a free crawl space inspection with an expert like AFS. We safely and thoroughly inspect crawl spaces and provide customized solutions.

Why is Crawl Space Insulation Essential?

Inadequate crawl space insulation causes numerous negative effects. These issues affect the crawl space and threaten the safety of your home and your family’s health. Insulating your home’s crawl space is crucial to safeguarding what matters most.

We advise against DIY insulation methods that often fail to address the underlying issues. Professional installation is far more effective. At AFS Foundation & Waterproofing Specialists, our proactive solutions are a part of our comprehensive approach to home care.

What Are My Crawl Space Insulation Options? 

Various types of insulation are used in crawl spaces. It’s important to obtain a professional inspection to learn more details. Here are the top three crawl space insulation types used in Tennessee, Alabama, and Georgia:

1. Fiberglass

Fiberglass insulation is a popular choice but not ideal for crawl spaces. This soft material is installed between the crawl space floor joists and rim joists to regulate floor temperature. However, fiberglass insulation is prone to moisture, mold, and pests. 

2. Spray Foam

Spray foam insulation is applied directly to surfaces like crawl space walls and joists to block extreme temperatures. Yet, it’s not the best option for crawl spaces. Most spray insulation types are closed-cell foams, which are robust but not impervious to damage. In a moist crawl space, spray foam harbors mold, emits chemical odors, and attracts termites. 

3. Foam Board

Fitted thermal foam board panels, like our exclusive ExTremeBloc™, provide superior crawl space insulation. These panels are custom-tailored and installed on interior crawl space walls. ExTremeBloc™ features a reflective surface for maximum heat retention.

    Crawl Space Insulation FAQs

    The R-value is an indicator of an insulation material’s capacity to resist heat flow. The higher the R-value, the better the material is at insulating, which means it can more effectively prevent heat transfer between your crawl space and the living areas of your home.

    Insulation typically lasts 15 to 20 years, but it can succumb to damage from mold and moisture if the crawl space is not properly encapsulated. AFS Foundation & Waterproofing Specialists recommend ExTremeBloc™ foam board insulation as a durable, lasting solution. Contact us to learn more and schedule a free inspection.

    The duration of a crawl space insulation project depends on the size of the crawl space, the extent of preparation needed, and other necessary repairs. Most installations by AFS can be completed in one to two days. Learn more and receive an accurate timeline during a free inspection.
