Air Sealing

Air Sealing - Delmarva Insulation

Energy efficiency is about more than insulation. An efficient attic includes air sealing. According to the Department of Energy, having your home air sealed by a qualified contractor can save up to 20% on heating and cooling costs.

Air sealing prevents airflow between a home and the attic. Proper air sealing helps heated and cooled air stay inside the home by closing the gaps that leak air. When a home isn’t properly air sealed, temperature-controlled air from the inside will flow out, and undesirable air from the outside will flow in. With a home that has not been air-sealed, staying warm in the winter and cool in the summer becomes an inefficient and costly endeavor.

There are several sources within a home that may be contributing to air leaks, including light fixtures, plumbing stacks, soffit drops, basement box sills, and more.

Attic Insulation - Delmarva InsulationInsulating your attic will greatly help in keeping temperature-controlled air in and unwanted air out. When upgrading insulation in existing homes, blown-in fiberglass is added on top of existing insulation using one of several industry-leading attic insulation products. This adds R-value (insulating power) to the home and creates a fresh new blanket of protection. Our team at Delmarva Insulation also offers a wide range of spray foam insulation services for unwanted air sources in hard-to-reach attic and rooftop zones, basement box sills, and more.

Do you have a newer home? Even newer homes can benefit from upgraded insulation. As building codes increase, nearly all homes need more insulation to ensure they are meeting current standards.
