Some foundation repair companies will tell you that you do not need to “waste money” on adding insulation, but this is a false promise to get you to buy their products. Your crawl space needs insulation and encapsulation because science is working in two ways; let’s examine them now:

Insulation vs. Encapsulation

Think about it this way: insulation works to regulate temperature while encapsulation works to regulate moisture. Building code dictates that you must have insulation in your home to create a thermal barrier between your house and your crawl space. This barrier keeps hot air in your house during the winter and cool air in your house during the summer. Without insulation, your unregulated crawl space would suck up all your heating and cooling efforts and cause your electric bill to skyrocket.

Encapsulation prevents moisture from getting into your crawl space and causing mold and mildew. Moisture can come up from the ground, seep through your home’s foundation, or come from condensation caused by your home’s A/C duct work. Coupling encapsulation with a dehumidifier is the best way to solve problems caused by moisture and prevent moisture from invading your crawl space. You have to have the two working together in your crawl space for the best results. Keep in mind that moisture will negatively affect your crawl space, but it doesn’t affect your home’s temperature – that is a separate issue that needs a separate solution.

Insulation is the solution for your temperature problem. It creates a thermal barrier that prevents heat sink.

What is a thermal barrier?

The air in your crawl space is a different temperature than the air in your home. If you don’t have insulation between your floor and crawl space, your HVAC will need to work twice as hard to regulate the air in both spaces. Heat sink happens when the hot air from your house sinks into your crawl space and your HVAC has to try to create a balance to keep everything even. Insulating the first floor of your home or the ceiling of your crawl space creates a thermal barrier for the hot air in the winter, or the cool air in the summer. Therefore, your HVAC won’t try to uselessly heat or cool your crawl space.
