Insulating Cantilevers
Take note of the soffit areas around your home and consider what they are connected to before you do any work to the area.  Strong consideration should be given to adding or improving insulation to the cantilever cavity prior to adding any soffit product so that once the soffit work is done, it is not necessary to take it down to treat the cantilever with insulation.

Cantilevers around Maryland homes are classic thermal bypasses.  A thermal bypass is the movement of heat around or through insulation.  A thermal bypass typically occurs due to missing air barriers or because of gaps between the air barrier and the insulation.

A poorly insulated cantilever can create hot and cold spots around a home in certain circumstances.  Cantilever insulation work requires a company that understands three trades in order to complete the project correctly.  Carpentry, siding and insulation techniques must all be in order. A contractor should be able to do the following:

1. Carefully remove the existing soffit material without damaging any of the siding or trim.
2. Properly remove the old insulation in order to block the cavity for insulation.
3. Properly insulate the cantilever so that once it is back in place, the work is done.
4. Reinstall the wood or vinyl soffit paneling to close up the area and seal it from the elements.
