Seal Building Penetrations

Caulking is an easy and inexpensive way to save energy and reduce costs. Studies of non-residential buildings in northern climates show a 40% to 70% reduction in infiltration and 15% to 25% reduction in heating costs.

Get this benefit by strategically applying caulk to holes, gaps, cracks, penetrations, and frames around windows and doors throughout the building. Also caulk channels in pipe chases and cavities extending from the floor to the roof.
