Do You Really Need Ventilation Duct Tape for Your Ducts?

2022-06-04

After so many years, you must be shocked to find that cloth duct tape is not suitable for your ventilation duct. Cloth duct tape can be used in a variety of ways, from fixing tents to removing flannels from clothes, but it’s a major taboo when it comes to actual air ducts! Do not use Cloth duct tape on ventilation ducts. Although this knowledge may be limited to professional and reliable HVAC technicians and eccentric homeowners who have tried DIY, now you know it.

 

The working principle of cloth duct tape is the same as that of using tape to seal or repair damaged items. For vent duct tape, it is made of Aluminum foil. It is the only tape type suitable for air duct. If your plumbing is not properly sealed, your home is less energy efficient. In areas where leakage is suspected, seal the affected area with foil duct tape.


There are countless types of Vent duct tapes on the market. Vent duct tape has different brands and different use cases, which completely depends on your specific needs. When it comes to choosing your vent duct tape. There are a few things you need to remember.


1.Backing

According to your specific needs, the back of the vent duct tape will be different. Different types of backing include pure foil, film laminated foil, scrim reinforced foil and other composite backing. The vent duct tape you choose will suit your specific needs. Remember that the type of backing protects the adhesive on the other side.


2.Adhesive and adhesion

It’s about how the tape sticks to the surface. You want your tape to stick to the surface immediately. The adhesive used can be acrylic, butyl or rubber based adhesive. In terms of adhesion, you want your tape to form a permanent and strong bond with your duct.


3.Ease of application

If the vent duct tape you choose doesn’t work well, you may want to find another one to replace it. The vent duct tape you choose needs to be of different sizes or shapes to effectively seal the leak.


4.Permeability

Look at how well the vent duct tape stops air from leaking out of your duct work and contaminants from entering your duct work. If it is permeable, then this ventilation duct tape is not the tape for your ducts.


5.Strength

See how well vent duct tape can prevent air from leaking out of your plumbing system and pollutants from entering your plumbing system. If it’s permeable, then this ventilation duct tape is not your duct tape.


6.Needs

Some tapes are flame retardant, some are completely fireproof. There’s also moisture-proof ventilation duct tape. You need to consult a professional HVAC technician to determine which ventilation duct tape is most suitable for your specific needs.
