What type of insulation for a crawl space is the most dependable and durable? Click here to explore everything you need to know.

Are you concerned about the quality of your home’s insulation?

A lot of people don’t know that the crawl space is an area where the house can leak or lose heat. This is due to a lack of proper insulation or insulation that’s not strong enough to keep heat in.

That is why you must learn more about the different types of insulation. With this, you know how to improve your crawl area.

Be sure to read below to learn more about what type of insulation for crawl space you need.

Spray Foam Insulation

Spray foam insulation is a popular choice for crawl spaces. This is due to its excellent sealing properties and high R-value (thermal resistance). It’s applied as a liquid and then expands to fill gaps and cracks, creating an airtight and moisture-resistant barrier.

Closed-cell spray foam is particularly effective. It provides a higher R-value per inch and acts as both insulation and a vapor barrier. This helps to prevent moisture intrusion and potential mold growth.

But, spray foam insulation can be more expensive than other options. Also, you need professional installation for best results.

Fiberglass Insulation

Pre-cut, flexible sheets of insulation made from glass fibers are relatively easy to install. Fiberglass is cost-effective. But, it’s important to note that it doesn’t provide as effective an air or moisture barrier as spray foam.

If you go for this option, make sure to seal up gaps really well and add a special sheet to stop moisture from getting in. Without proper sealing, fiberglass insulation can be less effective in preventing heat loss and moisture issues.

Rigid Foam Insulation

Rigid foam insulation panels are a versatile option for crawl spaces. They come in different materials. These include expanded polystyrene (EPS), extruded polystyrene (XPS), and polyisocyanurate (polyiso).

These panels have a high R-value and provide good moisture resistance when properly installed. Rigid foam insulation can be installed directly against the crawl space walls or on the crawl space floor, depending on the design of your space. It’s important to seal the joints between panels to prevent air infiltration.

Vapor Barrier

Regardless of the type of insulation you choose, a vapor barrier is a crucial component in crawl space insulation. A vapor barrier prevents moisture from migrating into the crawl space. This can lead to mold growth and other moisture-related problems.

It’s recommended to use a high-quality, durable vapor barrier that is properly sealed at seams and edges. In some cases, combining a vapor barrier with insulation that has built-in vapor resistance can be an effective strategy.

Professional Installation
