An uninsulated cantilever can lead to cold floors in a home. In a home with a cantilever, the rooms inside can react to outdoor temperatures when air is able to freely pass in and out of the cantilever, resulting in cold during the winter and heat during the summer. This type of comfort issue can result in higher than needed electric bills if the homeowner is relying on their HVAC unit to solve the problem but turning the heat up or the AC down. Dense packing the cantilever happens by cutting access holes and packing them with insulation.
