Types Of Under Floor Spray Foam Insulation

Spray foam insulation is perfect for insulating crawl spaces. As San Antonio’s number-one spray foam installer, SATX Spray Foam Insulation can install one or more types of spray foam insulation in your crawl space. Once we’ve sprayed this foam, it expands significantly, filling any hidden air gaps in your crawl space in the process.

There are essentially two types of spray foam insulation you can choose from. We’ve provided brief descriptions below, but our team can help you decide on the spray foam variety that’s right for you.

Open-Cell Spray Foam

This spray foam variety is water-permeable - that is, water can pass through it. That makes it ideal for ceiling and attic insulation since it makes leaks easy to locate and fix. It’s also more affordable than closed-cell spray foam, but it isn’t quite as effective when blocking the flow of heat.

Closed-Cell Spray Foam

Unlike open-cell spray foam insulation, closed-cell insulation can block both air and vapor. It boasts a considerably higher density than open-cell spray foam, making it great for crawl spaces and other underground areas. While it also comes with a higher price tag than open-cell foam, our team can help you save on this type of insulation, too.

We Do Crawl Space Encapsulation

If you have an open/vented crawl space, you may be at risk of additional problems related to insulation. The batt insulation commonly found in crawl space ceilings can degrade and fall off over time. Making matters worse, the vents included in these crawl spaces can introduce outside air to your home. Your HVAC system can then distribute this air throughout living areas.

The crawl space encapsulation services offered by SATX can solve these issues. Our team is capable of transforming your vented crawl space into an unvented crawl space by insulating and sealing its walls and floors. You’ll be able to control temperatures more effectively, cut down on unpleasant smells and allergens, and even prevent pests from entering your home!
