Sealing the duct system is essential for a variety of reasons, from preventing duct leaks to improving indoor air quality. With so many options available, it can be difficult to know which one is best for your needs. Two of the most popular choices are duct putty and duct tape (or aluminum tape).Both putty sealant and aluminum foil tape are good options for sealing air ducts. If you suspect that your boiler isn't working properly or that some areas of your house aren't as warm as other rooms, it's likely a leak in the duct system.
You can seal air duct leaks on your own, using an aluminum duct or aluminum foil designed specifically for duct use. A more permanent option is to apply a putty made to seal ducts. To ensure that your air ducts are sealed as completely as possible, it's best to contact a professional HVAC technician. This means that it would take you 3 to 4 years to pay the additional cost of hiring a company like Aeroseal to seal your air ducts. If you insist on using duct tape for any reason, it's best to use aluminum tape, butyl tape, or any other type of sealing tape that has the UL emblem.
However, I am skeptical of the longevity of the seal when using putty at the joints between sections of the duct. In general, the best way to seal ducting is to hire a professional to do the work by internally sealing the entire duct system. While duct putty is the best do-it-yourself choice in terms of durability and cost-effectiveness, sealing duct vents with putty yourself can be a difficult task. Hardcast recommends using Butyl Foil-Grip tape on galvanized steel ducting, duct panels, or flexible ducting. A duct seal is used to cover gaps around power lines and other small openings on the outside of your property. While duct sealant is designed to repel moisture, it is primarily used to seal air leaks, rather than leaks in pipes.
While this method of sealing duct vents is less time consuming and less dirty, it cannot be compared to other duct sealing methods in terms of performance and durability. When it comes to sealing air ducts, there are two main options: putty and tape. Putty is a more permanent solution and provides better insulation than tape. It also has better adhesion and can be used on any type of surface. However, it can be difficult to apply and requires more time and effort than tape.
On the other hand, tape is easier to apply and can be used on any type of surface. It also provides good insulation but doesn't last as long as putty. In conclusion, when it comes to sealing air ducts, both putty and tape have their advantages and disadvantages. Putty provides better insulation and adhesion but requires more time and effort than tape. Tape is easier to apply but doesn't last as long as putty.
Ultimately, it's up to you to decide which option is best for your needs. As an expert in air duct sealing, I recommend hiring a professional HVAC technician for the job if you want a long-lasting solution that will save you money in the long run. Putty is a great do-it-yourself option if you're looking for something more cost-effective and durable than tape. However, if you're looking for an easier solution that won't break the bank, then tape may be your best bet.
