Open Vent in Crawl Space
The problem with having vents in your crawl space is that in the winter they let in cold air which travels directly into your home. Floors above can become very cold due to cold air traveling between the floors and the insulation. In the summer time the vents let in hot air which mixes with the cool conditions of the crawl space. This causes condensation to form on everything throughout the crawl space. When this happens, microbial growth occurs which can attract insects and cause wood rot.
Crawl Space Vent Covered with SilverGlo
The Dr. Energy Saver Delmarva team has cut a piece of SilverGlo rigid foam board insulation to fit in the open area where the vent is. The SilverGlo will act as an extra barrier against the outside elements when placed directly behind the closed vent. Equipped with radiant barrier it will also keep extra heat from entering the crawl space.
Vent in Crawl Space Blocked Off, Insulated and Sealed
After installing the SilverGlo the Dr. Energy Saver Delmarva crew seals all around it ensuring that all holes and cracks are filled in. This will prevent air from leaking in. Now that the vent is blocked off and sealed the crew is ready to encapsulate the crawl space.
