Effectively heating and cooling your home is more than just adjusting the thermostat. The size of your home, the difference between the indoor and outside temperature, and your home's insulation play a larger role. All of these factors contribute to a home energy term called the "Stack Effect."
Older homes and new construction need rim joist insulation. The fiberglass batting and foam board we usually see in our walls, attics, basements, are not sufficient. DBS installs spray foam and rigid foam insulation to rim joists - preventing air leakage and protecting the overall energy efficiency of a home.
