When it comes to sealing ductwork, adhesive tape may be a quicker and easier solution, but it is often more expensive and less durable in the long run. A better option is to use sealing putty for air ducts. This is a sticky substance that hardens after application, and it is the best way to ensure your ducts are properly sealed. If you want to maximize the energy efficiency of your home, it is important to seal your air ducts.
Start by sealing air leaks with putty or metal tape and isolate any ducts you can access (such as those in attics, mezzanines, unfinished basements and garages). A well-designed and properly sealed ductwork system can make your home more comfortable, energy efficient, and safe.
How to Seal Ductwork with Putty
Sealing your ducts with putty is a relatively simple process. First, you need to identify any air leaks in the system. You can do this by using a smoke pencil or a smoke bomb.Once you have identified the leaks, you can use the putty to seal them up. Make sure to apply the putty evenly and press it firmly into place. Allow the putty to dry completely before testing the system again.
Maintaining Your Sealed Ductwork
It is important to note that sealing your ducts with putty is not a one-time job. Over time, the putty may become brittle or crack due to temperature changes or other factors.It is important to check your ducts regularly for any signs of wear or damage and reapply putty as needed.
