When you think about insulation, your mind probably jumps to your attic or the walls of your home—but there's one often-overlooked area that plays a huge role in home comfort and energy efficiency: the crawl space. If your home in Renton, WA, has a crawl space, proper insulation down there could be the game-changer you didn’t know you needed.
At Renton Insulation, we’re all about making your home more energy-efficient, comfortable, and healthy. In this post, we’ll explain what crawl space insulation is, why it matters, and what your options are. Let’s dig in!
What Is a Crawl Space?
First, let’s clarify: a crawl space is a narrow, unfinished space beneath your home, typically between the ground and the first floor. It’s usually just tall enough for someone to crawl through—hence the name.
While it might not be a place you spend time in, your crawl space can have a big impact on your indoor air quality, heating and cooling costs, and even the structural integrity of your home.
Why Is Crawl Space Insulation Important?

By insulating your crawl space, you’re taking a proactive step toward improving energy efficiency, protecting your home, and enhancing comfort.
Crawl Space Insulation Types
When it comes to insulating a crawl space, there’s no one-size-fits-all solution. The best option depends on whether your crawl space is ventilated or unventilated.
1. Fiberglass Insulation
2. Spray Foam Insulation
3. Rigid Foam Board
Don’t Forget the Vapor Barrier
In most cases, insulation alone isn’t enough. Moisture control is just as important. A vapor barrier—a thick plastic sheeting placed over the ground—is crucial for keeping humidity and moisture from seeping up from the soil.
When used with insulation, vapor barriers prevent mold growth, reduce pests, and help maintain consistent temperatures.
