Proper Crawlspace Encapsulation Practices

Thursday, January 12th, 2023 by Aaron Stull

Crawlspace encapsulation is the process of sealing and insulating the crawlspace beneath a home to improve energy efficiency and protect the structural integrity of the home. This process involves the installation of a vapor barrier, insulation, and a dehumidification system to control the relative humidity within the crawlspace. The benefits of crawlspace encapsulation are numerous and include energy savings, improved indoor air quality, and protection against wood rot.

One of the primary benefits of crawlspace encapsulation is the reduction of energy costs. A properly sealed and insulated crawlspace can help to reduce heating and cooling costs by preventing drafts and reducing the amount of air exchange between the crawlspace and the living space. By limiting the amount of air exchange between the crawlspace and the living space, encapsulation also helps to improve indoor air quality by reducing the amount of allergens and pollutants that can enter the living space.  In addition to this benefit, the floors above the crawlspace will finally be warm and comfortable.  Rather than the thermal barrier being the floor above the crawlspace, it is the ground below. Thus, the floors no longer are the end that gets cold.

 

 

Another significant benefit of crawlspace encapsulation is the control of relative humidity. High humidity levels in the crawlspace can lead to the growth of mold and mildew, which can cause health problems and damage to the home. A dehumidification system, such as the CleanSpace system offered by Keystone Basement Systems, can be installed to control the humidity levels in the crawlspace and prevent mold and mildew growth.

 

 

Encapsulation also helps to prevent the "stack effect" from occurring, which is when warm air in the living space rises and escapes through the crawlspace, drawing in cold air from outside. This can cause drafts and make it more difficult to maintain a comfortable temperature in the living space. By sealing and insulating the crawlspace, encapsulation helps to prevent the stack effect and improve the overall energy efficiency of the home.

 

 

In addition, encapsulation also helps to protect the structural integrity of the home by preventing wood rot. High humidity levels in the crawlspace can lead to the growth of mold and mildew, which can cause wood rot and weaken the structural elements of the home. By controlling humidity levels and preventing drafts, encapsulation helps to protect the structural integrity of the home and prolong the life of the home's foundation.  If structural damage has occurred, this can be fixed in conjunction with an encapsulation project.

Keystone Basement Systems specializes in crawlspace encapsulation and offers a variety of products to help improve the energy efficiency and structural integrity of the home. The CleanSpace vapor barrier is designed to seal the crawlspace and prevent drafts, while SilverGlo insulation is designed to improve energy efficiency and reduce heat loss. The TerraBlock insulation barrier is specially designed to be used in crawlspace, it is a high-density insulation that is also resistant to moisture.

 

 

Drainage matting is also a great product to be installed in the crawlspace, it is a heavy-duty plastic matting that is designed to channel water away from the foundation of the home and protect the structural elements of the home from water damage. It also helps to prevent mold and mildew growth by keeping the crawlspace dry.

 

 

Overall, crawlspace encapsulation is a cost-effective way to improve the energy efficiency and structural integrity of the home. By sealing and insulating the crawlspace, controlling humidity levels, and preventing drafts, encapsulation can help to reduce energy costs, improve indoor air quality, protect against wood rot, and prolong the life of the home's foundation.
