Why Crawl Space Ventilation is Needed in Addition to Crawl Space Encapsulation

Share this article

Crawl space encapsulation is a great first step to preventing moisture from entering your crawl space, but in order to keep this pesky moisture at bay, you’ll also need to invest in crawl space ventilation. Learn why and how WAVE Home Solutions can help.

What is Crawl Space Encapsulation?

Crawl space encapsulation is the act of installing a vapor barrier on the crawl space floor that continues up to the foundation wall, covering the floor and posts. The purpose of crawl space encapsulation is to create an environment that can be controlled for moisture by keeping moisture from the outside from coming in your home.

Crawl Space Encapsulation is a Great First Step But…

Encapsulation is good for keeping outside moisture from coming in, but you still need to manage the moisture lurking inside your home. Basically, encapsulation can keep moisture from the outside from coming in, but it cannot extract existing moisture nor indoor moisture generated from everyday living. Encapsulation will not expel harmful pollutants or other contaminants that can build up in the crawl space and make their way upstairs via stack effect. Sadly, crawl space encapsulation alone does not create the necessary air exchanges that expel and control moisture while improving the indoor air quality of the crawl space and the overall home..

Crawl Space Ventilation After Encapsulation

In order to make crawl space encapsulation worth your while, you still need to use an exhaust method to get the moisture out as well as keep it out. So, after you encapsulate your crawl space, invest in a crawl space ventilation system.    

How the WAVE System Can Help

The WAVE System is a mechanical ventilation system that not only ventilates, controls moisture, and expels pollutants and odors in your crawl space, but it also improves the overall air quality of your whole house.

In order to keep your home healthy and dry, the WAVE System does three very important things:

  • Expels
  • Replenishes
  • Ventilates

Expels

This state-of-the-art ventilation first measures the relative humidity of your crawl space to determine how much air to exhaust. It then expels moisture, odors, stagnant air, radon, toxic vapors and indoor pollutants.

Replenishes

The system’s booster fan simultaneously brings down an equal amount of warmer, drier, fresher air from upstairs to replenish the air and maintain balanced air pressure.

Ventilates

The WAVE system increases circulation for moisture extraction from your home’s walls, floors and beams, reducing mold activity, odors, insects, dust mites. It reverses natural air flow so that poor air quality doesn’t enter the living area and creates air exchanges that improves the indoor air quality for your whole house.
