This is an addition to a summer cottage that has been winterized. The addition was framed, and sealed by a rubber compound new to construction methods. The rubber compound helps secure the framed addition to wind-tight condition, and is an alternative to sprayed insulation. Although an extra step, it is actually a cost-effective construction method that will serve the homeowners well. The photos depict the rubber sealant, as well as the point of connection between the addition and the existing dwelling.
