Insulation Services Case Studies: Cold Floors - Leesburg, VA
This home in Leesburg, VA was suffering from cold floors. The homeowner couldn't even walk around the house in the winter without slippers or shoes on. Comfenergy found the entire house to be over a vented crawl space. This was allowing cold air beneath the floors above. Even though there were batts of insulation beneath the floor, the cold air was getting between them and making the floors cold.
Comfenergy removed all of the existing insulation and disposed of it properly. Terrablock foam boards were installed on the crawl space floor to keep the cold ground from "sucking up" all the heat from above. Then, we installed CleanSpace (a 20 mil thick vapor barrier made of anti-microbial materials) that will never mold or mildew. Finally, the vents were sealed and closed cell foam spray was sprayed on all the walls. This totally "encapsulates" the crawl space and turns it into conditioned space. The crawl space is now within 10 degrees of the living space above and is dry. A Sani-Dry dehumidifier was also installed to make sure everything stays dry moving forward.

Closed cell foam being sprayed on the crawl and basement walls. This makes these areas completely air tight and very well insulated. No more cold air getting in here!!!
The crawl space access door being prepped with air tight foam strips. We want to keep out as much cold air in the winter and hot air in the summer as possible.
Here is an image of the basement wall after installing the closed cell foam spray.
Another close-up of the closed cell foam spray. Totally air tight! Now the floors above will be nice and cozy forever!
