Duct Sealing Before | Attic Insulation & Air Sealing by First Defense Insulation


The ductwork shown here is not sealed or insulated, meaning it is exposed to both air leaks and temperature swings based on the temperature of the attic. This has a huge impact on the efficiency of the ductwork and the temperature of the air being blown into your living space.

Why choose spray foam?

Why duct insulation is important to energy efficiency

The attic is prone to more extreme temperature swings than the living space, and it is typically much colder in the winter and much hotter in the summer than the rest of the house. When your ductwork is in the attic, this temperature change has a major impact on your home’s efficiency.

In the winter, you’re paying to heat air from your furnace then sending it through cold ductwork in the attic. This cools the air down and sends it to the living space at a lower temperature, which forces your furnace to run longer to heat up your home and wastes money. The reverse is true in the summer as cool air from the air conditioner runs through hot ducts in the attic.

Duct insulation eliminates these problems in your home. Duct insulation protects the ductwork from extreme attic temperatures and maintains a consistent temperature, meaning the air you pay to heat and cool isn’t affected as it moves through the ductwork. This greatly improves efficiency and will save you money while making your home more comfortable.
