Everything You Need To Know About Crawlspace Insulation

Posted on: 1 June 2022

When you own a home, there is always another project to do or annual maintenance to keep up with. If you have a crawlspace, making sure the space is clean, dry and pest-free is important. Crawlspace insulation services can help you with this task. Here's what you need to know about crawlspace insulation.

What is a crawlspace?

A crawlspace is a type of foundation. It is a small, unfinished area beneath a home. A crawlspace is typically used for storage or as a space to access the home's plumbing and wiring.

Do crawlspaces need to be insulated?

Crawlspaces need to be insulated if they are enclosed. An uninsulated crawlspace can lead to moisture and mold problems, as well as increased energy costs. Furthermore, in colder climates, an uninsulated crawlspace could lead to frozen plumbing lines.

What are the benefits of crawlspace insulation?

There are many benefits to crawlspace insulation. Some of these benefits include:

  • Reduced energy costs
  • Improved indoor air quality
  • Reduced risk of moisture and mold problems
  • Decreased noise from outside

Additionally, crawlspace insulation can help to protect your home from pests and insects.

How do you insulate a crawlspace?

There are two main types of crawlspace insulation:


A vented crawlspace has vents that allow for air circulation. This type of crawlspace is typically found in warmer climates. The vents help to keep the crawlspace dry by allowing moisture to escape.


An unvented, or sealed, crawlspace doesn't have vents. This type of crawlspace is typically found in colder climates. The lack of vents helps to prevent cold air from entering the home.

What are the different types of crawlspace insulation?

The different types of insulation used in a crawlspace include:

  • Fiberglass batts. This type of insulation is typically yellow or pink and comes in long rolls or batts. It is placed between the floor joists.
  • Spray foam. Another type of crawlspace insulation is spray foam. It is sprayed onto the underside of the floors and expands to fill the space.
  • Rigid foam board. This type of insulation is made of rigid foam and is placed against the foundation walls and adhered to the floor joists above the crawlspace.
  • Loose-fill fiberglass. This type of insulation is blown into the crawlspace with a machine. It is typically used in hard-to-reach areas.

Additionally, when insulating a crawlspace, a moisture barrier, sometimes called a vapor barrier, is adhered to the floor joists after the insulation is installed. This thin sheet of plastic helps keeps both water and pests away from the insulation.

What is the best type of crawlspace insulation?

The best type of crawlspace insulation depends on the specific needs of the home, the climate the home is located in, and the amount of headroom in the crawlspace.

In conclusion, crawlspace insulation is important in order to reduce energy costs, improve indoor air quality, and decrease the risk of moisture and mold problems. Call a professional service for crawlspace insulation services today.


What's In a Contract?

Those who build things and repair things for a living are often referred to as contractors. This may seem like an odd term, but it traces back to the fact that these folks work on a contract-by-contract basis. First, they may work under a contract associated with your home. Then, they may take on another client under a new contract. Plumbers, HVAC repair teams, builders, painters — they are all contractors in some way. Construction workers are also contractors. We encourage you to read and learn more about their professions and what they involve here on this blog, where we'll post often.
