This Woodbridge, VA home had issues with cold drafts in the winter. Comfenergy crews are setting up to properly air seal and insulate the rear of this home.
The beginning of opening the cantilevers and other poorly insulated areas.
Cantilevers like this allow cold air into the home in the winter... see the following few pics to see why!
Once the cantilever was opened you can see that no insulation was present, allowing air to travel into the home and especially under the floors.
This picture is taken from inside the cantilever. You can see how cold air can travel beneath the floors and above the ceilings below. This pipe could have easily frozen if it were closer to the exterior of the home.
The cantilevers were sealed and insulated using foam boards and closed cell spray foam.
