Crawl Space Encapsulation

      Fully encapsulating a crawl space-by both sealing and insulating-is a fully efficient measure in addressing crawl space problems. It makes sense to maintain and improve the lower level area in order to maximize healthy living conditions and home resale value. Crawl space encapsulation involves sealing all outside vents, installing a high-performance vapor retarder on all exposed wall and floor surfaces at or below grade, insulating the walls and rim joist, and conditioning the air. In addition to dramatically increasing indoor air quality and protecting the structure of your home, several research studies from Advanced Energy indicate that crawl space encapsulation can actually lower energy usage.

     A zero perm liner system that also insulates and reflects heat provides the most benefits. With a proper floor and wall liner, the area will not only be well insulated, but will seal out moisture, and prevent mold growth. A zero perm liner will also completely weatherize the crawl space and save on energy bills since the outside air won't be able to leak into the home.

     Crawl space encapsulation prevents indoor air pollution. The Environmental Protection Agency (EPA) lists indoor air pollution as one of its top five environmental risks. While there are a number of causes of indoor air pollution in your home, a damp crawl space is one significant danger. Because of an effect called the "stacking effect," half of the air you breathe in your home actually comes from underneath your house and up through the ventilation system. This occurs because warm air rises and escapes through leaks in your home, causing colder air to be pulled in and up through craw lspace vents and into your house. When the crawl space is damp, it likely will have dust, mold spores, allergens and soil gases in it, which will then be dispersed throughout your home.

Our encapsulation systems include the following benefits:

  • Energy Star Rated
  • Increase your heating/ cooling efficiency
  • Reflectivity value of 97% to prevent radiant heat loss
  • Class A / Class 1 fire rating
  • Eliminate mold and fungus growth
  • Increase Air quality throughout the home
  • TRC is proudly serving customers in these areas
