Encapsulating a Crawl Space in Unionville, CT

This homeowner in Unionville, CT called us hoping that we would be able to take a look at his insulation. He was experiencing a lot of issues with rooms that were uneven temperatures. When our Home Comfort Specialist arrived in the home, he noted that one issue in the home was the crawlspace. It was poorly insulated and unencapsulated, meaning that cold air was coming in from outside and traveling through the entire house. 

We were able to help this homeowner by utilizing our CleanSpace™ crawl space encapsulation system - with a few modifications for the home itself.

We started by utilizing our two-part expanding spray foam to insulate around the base of the (now unused) chimney that is in the crawl space. Then, we got to work. We started by adding SilverGlo™ foam board insulation on the walls. SilverGlo™ has graphite infused into the foam, increasing its R-value by 24% over standard foam. Then, we added two-part expanding spray foam to the rim joist and over the sill plate until it met the SilverGlo™, forming a barrier. Then, we laid out dimpled drainage mat on the floor, creating airspace as well as a thermal break. Dimpled drainage mat also has the bonus of forcing any water that may occur under the mat to go to the lowest point of the crawl space. We then added TerraBlock™ floor insulation over top of that. After that, we installed our heavy duty CleanSpace™ encapsulation liner, sealing it to the walls and floors. 

Now, this homeowner's crawl space is insulated and encapsulated -- causing the home to have less drafts and cold floors. They are much more happy!
