To ensure that air leaks are prevented and energy consumption is reduced, it is essential to seal the ducts along the entire length of the duct system. Aeroseal is a unique approach that is easier and less invasive than other duct sealing methods and is usually more effective at sealing leaks. Sealing air ducts while ignoring other air gaps in your home is like leaving most windows open and then wondering why wasps keep flying into your house. According to ENERGY STAR, if you properly seal your ducts, you could reduce your home's energy consumption by up to 20%.
At Sealed, we rarely recommend sealing ducts on their own, as sealing air throughout the house is very important for overall energy efficiency and comfort. Begin by sealing air leaks with putty or metal tape and insulating any ducts you can access (such as those in attics, mezzanines, unfinished basements and garages). If your home qualifies, you may be able to get a complete home air sealing package (including duct sealing and insulation improvements) for no money up front. A well-designed and properly sealed ductwork system can make your home more comfortable, energy efficient and safe.
Rather than relying on traditional methods of sealing ducts from the outside in, Aeroseal uses a thermopolymer adhesive to seal ducts from the inside out. This revolutionary technology can seal even the smallest holes in ducts. For the vast majority of homeowners, the best way to think about self-sealing ductwork is as an interim measure. If you're like most American homeowners, your recycle bin is full of advertisements for various duct repair and sealing services.
However, it is important to remember that sealing air ducts is just one small piece of the air-sealing puzzle in the home. To ensure that your home is energy efficient and comfortable, it is essential to seal all air gaps throughout the house.
