What is Crawl Space Encapsulation?

Energy Conservation Solutions offers crawl space encapsulation services because we care about the world and you. Crawl space encapsulation is, essentially, sealing your crawl space off from outside air and humidity using vapor barrier, spray foam, and a method of air circulation. It creates a clean operating environment for HVAC and duct work which eliminates mold, warms up the floors in winter months, and helps keep bugs and critters out.

Crawl Space Encapsulation Procedure

Crawl space encapsulation can be a complicated process, which is why Energy Conservation Solutions is here to help. The process entails installing a sturdy, reinforced vapor barrier along the entire floor of the crawlspace, then sealing it along all seams and at least 6″ up all piers and foundation walls for complete coverage. This prevents ground moisture from entering the air. Different types of vapor barrier can be used, ranging in material type to difference in mils. Reinforced polyethylene vapor barriers are the most commonly used vapor barrier type because they are the most durable and reliable, although unenforced polyethylene vapor barriers are also available. They come in differing thicknesses, or mils, ranging from 6 mils to 20 mils, and Energy Conservation Solutions proudly offers each type. Closed-cell spray foam is then applied along the foundation walls, piers, and the top of the rim joist to seal off the crawl space from outside air. To circulate and avoid stagnant air in an encapsulated crawl space, a few different methods of ventilation can be used, depending on which is best for your home: running a supply and return line to your HVAC unit, using a dehumidifier, or using a small exhaust fan.

Reasons You Need Crawl Space Encapsulation

Crawl space encapsulation can make a big difference to your home, especially here in Georgia’s climate. Vapor barrier encapsulation prevents mold growth, which can affect the HVAC ductwork and so provides cleaner air. It keeps water and humidity from building up or getting into the crawl space, and it keeps those unwanted pests like termites or opossums from setting up camp under your feet. It also keeps your floors warmer in the cooler months. All of these differences can help save you the money you would have spent on pest control and repairs. While encapsulated crawl spaces are unquestionably better than vented crawl spaces, vented crawl spaces are still commonly found in many homes in the region, which can cause several problems to arise. Some of the most common issues we’ve seen in vented crawl spaces in the north Georgia climate are listed below:

Poor air quality

The damp environment in the crawl space is often a breeding ground for mold and other growth that can negatively impact indoor air quality, leading to health problems. Crawl spaces allow air from beneath your house into your conditioned living space through the various penetrations along your subfloor and through the exterior wall cavities. Insufficiently sealed HVAC ductwork located in crawl spaces can also draw crawl space air into the HVAC system and distribute it inside your home.

Infestations

Insect and critters are well-suited to living in the dark, temperate climate under your home. All too often, these pests can make it into your living space from below, causing problems such as fleas, aggravated allergies, and damages.

Structural and mechanical damage

Buckled floors, rusting pipes and ductwork, and rotting of structural woodwork are all commonly seen due to the high humidity present for prolonged periods in the Atlanta climate.These issues can seriously affect the safety and sturdiness of your home, as well as cost a good chunk of money and deliver a lot of headaches.

What is ‘Crawlspace Encapsulation’?

An excellent solution for many vented crawlspaces is to encapsulate the crawlspace. What is ‘encapsulation’?

Encapsulation simply means the sealing up of your crawlspace from outside air and humidity. This entails installing a sturdy, reinforced vapor barrier along the entire floor of the crawlspace sealed along all seams and at least 6″ up all piers and foundation walls for complete coverage. This seals off the earthen floor which prevents ground moisture from entering the air. Closed cell sprayfoam is then applied along the foundation walls and piers and along the top of the rim joist to seal off the crawlspace from outside air. To circulate and avoid stagnant air in an encapsulated crawl, a small return and supply line is then run into the crawlspace from your HVAC air handler. This has the added bonus of warming the floors in the cold winter months. Alternatively, if your duct system is not easily accessible from underneath the house, you can install a dehumidifier.
