Attics & Air Sealing

Attic insulation and air sealing play a key role in saving money and increasing energy efficiency. A home loses 70% of energy through the attic and roof – far more than is lost through windows or doors. There are three steps to making your attic energy efficient:


1. Air Seal

Air sealing prevents airflow between a home’s living space and the attic, keeping heated and cooled air inside the home by closing the gaps that leak air. Some leaks can be easily spotted and visible to the eye. Other leaks can be found around light boxes, plumbing stacks, soffit drops, basement box sills and more.

To take air sealing a step further, consider air sealing top plates during the construction process (also known as the upper wall plate or ceiling plate). Air sealing top plates reduces air transfer from conditioned living space to unconditioned attic space. This can also be done from the attic in an existing home or during a remodeling project.

2. Ventilate

Proper ventilation allows the entire attic system to work properly, preventing moisture build up and allowing the insulation to properly do its job. Planned ventilation is the key to an energy-efficient home. Attic ventilation helps moves heated air out of the attic during the summer and cold air out of the attic during the winter.

3. Insulate

Insulating is the final step in making your attic more efficient. When adding insulation to the attic of an exiting home, blown-in fiberglass insulation is added over the top of existing insulation to add R-value to the home.


Even if your home is newer, it could benefit from upgraded insulation. As building codes increase, nearly all homes need more insulation to ensure they are meeting current standards. Contact us today for a free estimate.
