What is Crawl Space Insulation

Crawl space insulation is an energy-efficient material that maintains a comfortable and healthy indoor environment. It reduces cold winter air infiltration and blocks the intense Texas summer heat, reducing strain on your HVAC system.

Crawl space insulation is most effective when combined with our comprehensive encapsulation system. This approach seals the area from ground moisture and outdoor air, offering complete moisture control. This method regulates humidity, lowers energy bills, and improves indoor air quality, contributing to a healthier and more comfortable home.

Signs You Need Crawl Space Insulation 

There are several signs that indicate the need for crawl space insulation, including:

damp, moldy crawl space with damaged insulation

These issues indicate crawl space moisture that can lead to serious damage. Schedule a free inspection with FSS crawl space professionals for an expert diagnosis. 

Is Crawl Space Insulation Necessary?

Crawl space insulation is vital for your home’s comfort and protection. Neglecting insulation issues leads to increased moisture and humidity, which fosters harmful mold, pest infestations, and respiratory health issues.

At FSS, we encourage early intervention to preserve your home’s structure and your family’s health. We do not recommend DIY crawl space inspections or insulation, as these areas are hazardous, and store-bought solutions fail to address the underlying issues.

Trust crawl space insulation replacement and installation to experts like FSS. Our professionals provide thorough crawl space assessment, repair, and protection.

Crawl Space Insulation Types 

There are three prominent types of crawl space insulation used in Texas homes. These include:

damaged fiberglass insulation

Fiberglass Insulation 

Fiberglass insulation is the most commonly used insulation type in Texas homes, although it is the most unsuitable for crawl spaces. It easily succumbs to moisture, mold, and pests.

Spray Foam Insulation 

Spray foam insulation is also a popular choice for crawl spaces, but it is susceptible to mold and chemical odors and attracts pests, making it a less favorable option. Other insulation types better resist these issues and offer more reliable protection.
