How Much Energy Will Insulating a Crawl Space Save in New Jersey?

Today, around fifteen percent of homes have crawl spaces. These areas are popular in homes because they can create easy access to electrical systems and plumbing when needed. Since crawl spaces are open, they allow for efficient ventilation to keep your home cool during the summer and warm during the winter.

According to the EPA, insulating your crawl space can save you around 15% on energy costs. As you continue reading below, we’ll discuss crawl space energy savings and five ways you can insulate your crawl space to save on energy.

How Much Energy Will Insulating a Crawl Space Save?

When you insulate your crawl space, you can reduce the energy you use in your home. Crawl space insulation helps keep the air inside your crawl space and prevents it from affecting the inside of your home.

According to the EPA, insulating your crawl space can save you around 15% on energy costs. Insulating your crawl space can protect your home from dangerous weather like heat waves and extreme cold. In addition, if you have vents that run through your crawl space area, insulating your crawl space can prevent your vents from losing heat.

5 Ways to Insulate Your Crawl Space to Save on Energy

As a homeowner,, when you want to reduce energy costs, windows, and doors are the first thing that comes to mind; however, many homeowners need to remember about their crawl space. Crawl spaces are essential to keep your home energy efficient.

Just as crucial as preventing moisture in crawl spaces, it’s necessary to prevent unwanted drafts from using too much energy. To help maintain its condition and save on energy, there are several ways you can insulate your crawl space in several ways.

1. Insulate the Entry Door to Your Crawl Space

Similar to your front entry door, keeping the door of your crawl space insulated is essential. No matter the location of your door, your door should remain airtight at every access point. Keeping your crawl space door airtight will help regulate the temperature throughout your crawlspace, in turn helping regulate the homes temperature.

2. Insulate & Seal Ducts

Many homes with crawl spaces also have air ducts and plumbing between their joists. As air ducts are connected to the rest of your home, it’s essential they don’t have any holes or gaps. An air duct that leaks can affect efficiency by:

The air throughout your home that travels through your air ducts will escape into your crawl space.
Unwanted outside hot or cold air can enter your crawl space and spread throughout your home.

Depending on the ducts in your crawl space, there are different insulation duct wraps that you can use. Most insulation duct wraps are made from fiberglass with a protective foil to prevent mold growth and condensation. Having this extra insulation can make a tremendous impact on your energy savings.

3. Remove Insulation From Floor Joists & Plug Gaps

If you’re dealing with insulation other than spray foam, you can remove the insulation from the joists and inspect your crawl space floor for gaps. You should inspect any area that has plumbing or electrical wiring carefully. Fill any gaps with insulation that can prevent mold growth and save energy costs.

4. Insulate the Perimeter of Your Walls

When your crawl space has insulation on the walls, the area can better regulate its temperature and prevent your crawl space from becoming too hot or too cold. An added benefit of this method is that a professional won’t need to remove insulation to access plumbing or air ducts between your joists.

In addition, it’s also a great idea to add crawl space insulation to the perimeter of your walls when you have a vapor barrier on the ground.

5. Control Your Climate with a Dehumidifier

Finally, when it comes to controlling your energy usage, you can control the temperature in your space with a dehumidifier. A dehumidifier will ensure the crawl space remains comfortable and does not reach extremes. Dehumidifiers, including proper insulation, can also help prevent moisture and mold from forming in your crawl space.

Preventing drafts and air from traveling from your crawl space to inside your home can make a tremendous impact when saving energy. These five ways can help your crawl space and home become more energy efficient.

Crawl Space Encapsulation Energy Savings

One of the most significant benefits of crawl space encapsulation is energy savings. Crawl space encapsulation can make your home more energy efficient and can allow you to save, on average, 18% more energy.

Crawl space encapsulation creates significant energy savings and is highly recommended by the U.S. Department of Energy’s Building America Initiative.

The Stack Effect

You may or may have yet to hear about the stack effect. When the air in an area is heated, it rises and can escape through the upper levels of your home. When this happens, air can get sucked through any gaps in your crawl space.

At the same time, the air you’re running from your HVAC system leaks, causing it to work harder than needed. With crawl space encapsulation, you can completely seal your foundation and keep the outside air from entering your crawl space.
