Benefits of Crawl Space Insulation

Improving Energy Efficiency

When moisture, dust, and filth enter your home through the crawl space, your home’s HVAC system must work harder to adjust for the temperature and air quality changes. Crawl space insulation prevents this from occurring and increases the efficiency of your HVAC units. As a result, you’ll be able to save a lot of money on your energy cost.

Improved Quality of Air in Your Home

Crawl spaces are a breeding ground for bugs, rodents, mold, and mildew. The pollutants seep through the floorboards inside your house and decline the air quality inside. This can lead to a variety of health issues. Insulation keeps moisture, pollution, and other allergens out of the house, sealed in your crawl space, improving the quality of the air inside.

Mold and Wetness

Mold, wetness and freezing temperatures can all cause problems in crawl areas. Installing proper insulation can help with a lot of these crawl space insulation problems.

Enhanced Comfort

You will be able to reap varying benefits from an insulated crawl area depending on the type of insulation you have placed. Insulating the crawl area minimizes the cold drafty feeling that comes through the floorboards and makes them considerably more comfortable to touch.

Types of Crawl Space Insulation

Spray Foam Insulation

Spray foam insulation Is clean and efficient, and we believe the best type of crawl space insulation. The closed-cell spray foam is applied to the perimeter crawl space wall. It provides twice the insulation value, as well as, hardens to provide added structural integrity to the brick and block. It also becomes a moisture barrier for the wall.

Fiberglass Insulation

Fiberglass batts are used to insulate crawl spaces between the exposed joists. Usually, six-inch R-19 fiberglass insulation batts are used with the paper moisture guard facing the living area and hung securely without compressing.

Cellulose Insulation

Cellulose batts can also be used for crawl space insulation. Made up of 90% recycled materials, cellulose is green and sustainable. It reduces noise as well as provides thermal insulation. 

Types of Crawl Space Insulation

Spray foam, fiberglass, and cellulose are the insulation products available at Green Apple Spray Foam. Homeowners prefer spray foam insulation in crawl spaces due to its longevity and ease of application, however, situations vary and there might be several factors to consider before choosing the right type of insulation for your crawl space.

Whether a crawl space is ventilated or unventilated is one factor to consider while insulating it. Another factor to consider before choosing the type of crawl space insulation is whether the crawl space had been insulated before or not. Accessibility to your crawl space might be another deciding factor. Some crawl spaces are very narrow and make it very difficult to reach. Others are quite wide and easily accessible.

What People Say

Every time you hear the heat kick, or the air conditioning start up again, its costing you money.

How do We Insulate a Crawl Space?

We look inside your crawl space and measure the thickness of any insulation we find there. We find out the thickness of insulation to determine the R-value. R-value is greatly reduced when batts are pinched or drooping.

Insulation can be used to fill a variety of voids in crawl spaces. Rim joists will be insulated and air-sealed. Insulation and vapor barriers will be placed. Along the crawl space’s outside foundation walls, insulation will be installed.

FAQs

An encapsulated crawl space is different from a wall-vented crawl space in two ways. First, a continuous vapor barrier is installed on the floor and the outer walls in an encapsulated crawl space. On the other hand, a wall-vented crawl space has a floor liner installed. Secondly, the foundation vents are sealed in an encapsulated crawl space whereas the wall-vented crawl space has open foundation vents.    

Foundation vents should remain sealed as it results in a clean, dry, and energy-efficient crawl space. 

You might need to replace your crawl space if it is ruined by moisture, pests, or rodents. You might also need to air seal it properly. If the insulation is in good shape, you don’t need to replace it.

Most of the crawl spaces smell bad because of various reasons. One reason is the fact that the open foundation vents bring in humid air and cause mold growth. The moisture can also harm the wooden subfloor causing it to decay and stink. Another reason could be the absence of a vapor barrier, which causes it to take on a musty-earth-dirt-smell. Similarly, unwanted animals and pests cause odors in crawl spaces.  

Spray foam is often the best application in crawl space situations.

Crawl space encapsulation is a process in which a tough moisture barrier is installed on the floor of a crawl space. Furthermore, the foundations’ vents are sealed, walls are insulated and a crawl space dehumidifier is installed. Encapsulation results in completely air sealing the space.
