What Type of Sealant is Used for Air Duct Sealing Service?

When it comes to air duct sealing, there are various types of sealants available. However, duct sealing putty is one of the most effective and reliable options. This type of putty is easy to operate and install for many HVAC purposes, but is mainly used to seal holes and leaks. It's the best choice for blocking dust, moisture, noise, and air movement through duct holes and works better than duct tape. Aeroseal is a sealant developed at the Lawrence Berkeley National Laboratory to fill energy leaks in buildings.

This sealant was created due to the difficulty of sealing ducts from the outside, especially in hard-to-reach areas. To properly seal duct ventilation grilles, you must use high-quality duct sealing materials. Start with a silicone-based duct sealant that can be easily applied with a putty gun. This sealant will fill in the gaps and holes and, at the same time, keep moisture out. If you have duct leaks and want to repair them, you can try several methods to seal duct vents.

While duct putty is the best DIY option in terms of durability and cost-effectiveness, sealing duct vents with putty yourself can be a difficult task. You can use special air duct sealing tape, available at your local hardware store, to seal leaks and cracks. A duct seal is used to cover gaps around power lines and other small openings on the outside of the property. For the most complete duct sealing, contact a professional HVAC technician. Your technician will be able to seal all leaks in your duct system (even unreachable sections), but he will also be able to clean and isolate them to increase efficiency and improve indoor air quality.

Increase energy efficiency and reduce the amount of allergens and air pollutants in your home by investing in sealing, insulation, and duct cleaning by a professional HVAC company. However, if more dust than usual gets into your home, especially around ventilation grilles, it may be a sign that you need to buy an air duct sealant. Now that you know what type of sealant is used for air duct sealing service and that it can help make your HVAC system more efficient, it's time to learn when and how to properly use it. To reduce air loss and increase energy efficiency, it is recommended to seal all joints and add insulation around ducts, especially in unconditioned spaces. The specialist will then measure the leaks and offer you a comparison of the leaks in the front and rear air ducts. With this information in hand, you can make an informed decision about whether or not you need to invest in air duct sealing services.
