What You Need To Know About Crawl Spaces

Here are a few factors to look out for during crawl space cleanups.

Crawl space insulation

A crawl space is an excellent place to keep items, but it can also be an origin of concerns if not properly insulated. It is significant to remember that you can choose from various types of insulation to use depending on your location’s climate and the layout of your home.

Fiberglass batts are common insulation for crawl spaces, but several other options exist too, such as cellulose, closed-cell foam, and spray foam.

Crawl space vapor barriers

If crawl spaces exist in your home, it is best to consider installing a vapor barrier. Vapor barriers keep moisture out of the crawl space, which can help prevent mold and mildew from growing and inflicting damage.

Here are a few different types of vapor barriers that you can choose from:

  • Polyethylene sheet is the most common type, a plastic sheet that is waterproof and tear-resistant.
  • Asphalt felt
  • Fiberglass insulation
  • Aluminum foil

In choosing vapor barriers, there are certain factors you have to remember. The following shall explain what those components are and why they are needed:

  1. It’s essential to think about your local climate while selecting a vapor barrier that would suit your crawl space. If your area is humid, you’ll need a watertight and moisture-resistant vapor barrier. If you are in a dry place, you might be able to get away with a non-waterproof vapor barrier.
  2. Know the size of your crawl space. You’ll need a small vapor barrier to fit within your crawl space if it’s small. If your crawl space is large enough, a vapor barrier covering the entire area may be an option.

After meticulous deliberation and choosing a suitable vapor barrier, it is important to install it properly. Please read the instructions carefully to know how to install it. Improper installation can lead to moisture problems in the crawl space.

Why This Matters

Crawl space encapsulation, or the process of adding a barrier inside your crawl space, does so much for your house’s integrity, safety, and long-term value. Its many benefits include the following:

  • Reduced moisture problems: The vapor barrier prevents moisture from rising from the ground and damaging the crawl space and the home above.
  • Better pest control: The sealed crawl space creates an environment inhospitable to pests, such as termites, mold, and mildew.
  • Improved air quality: The sealed crawl space prevents outside air and moisture from entering, which can improve the air quality in the home.
  • Increased energy efficiency: The insulation can help keep the crawl space cooler in the summer and warmer in the winter, saving energy and keeping your utility costs low.

The type of vapor barrier you pick for encapsulation depends on your specific needs. But regardless of which one you get, you need to make sure of the following things:

  • It should have a high perm rating: A vapor barrier with a high perm rating will allow moisture to escape from the crawl space, preventing mold and mildew growth.
  • It should be puncture-resistant: The crawl space is a harsh environment, so it’s essential to choose a vapor barrier that is thick enough to resist punctures from rocks, nails, or other debris.
  • Installing it should be easy: Choose a vapor barrier that is convenient to install to save time and effort.
  • A warranty should back it: A warranty will provide much-needed assistance in case the vapor barrier fails.

Remember that working in low-ceiling areas is risky. Call an HVAC expert to lend a hand for repairs, inspections, and replacements.
