Customer Questions & Answers

How suitable is this for electrical applications?

Is the surface of the tape conductive, or is it insulated with something like polyester film? Is the adhesive conductive?
Asked by: ECEguy
Surface is conductive, adhesive is non-conductive, it can be used to make a Farday's cage for shielding electronics from RF interference, such as lining the body cavities of an electric guitar to stop the 60 cycle RF hum . However, copper tape is still a better choice since all the seams can be easily soldered to ensure good continuity for proper conductivity between pieces.

1.89 in. x 50 yd. 322 Multi-Purpose HVAC Foil Tape is rated 4.5 out of 5 by 413.

After installing a new furnace, there was a shrill whistle sound coming from around the ductwork. Looking further I found a fairly large gap around where the plenum brings air into the new furnace, I noticed the installer had used foil tape to seal off all the joints. So, I bought this , sealed the openings around the plenum like taping a box. Sure enough, sounds gone. Great for sealing off air leaks in duct work, like returns and supplies, also gas clothes drier. Better than cloth tape. Easy to work with since it has a release paper protecting the adhesive. And it sticks very well.

I used this foil tape to seal the stovetop air vent connection to the roof vent. It is a very strong tape, and adhesive, that is also heat resistant and was perfect for this job.

Rated 1 out of 5 by from I think I chose the wrong type of tape. Does... I think I chose the wrong type of tape. Does not work well at all for reflectix install inside of rv windows, or holding a/c vent in place (plastic, attached to inside of screen); sticks to my fingers and not much else (probably duct work but I didn't use it for that). Should have bought another roll of 3M 3350 or Flex??. The 3M tape worked extremely well on a number of projects, holds up well in extreme heat conditions, yet peels off easily when I need it to. It is also MUCH easier to work with in variety of spaces and materials. This foil tape was stiff, difficult to mold in corners and edges, and comes off in high heat situations (100 degree) then sticks to other things you don't want it to stick to. Like I said, I chose wrong.

Our double wall rooftop flue extension had rusted through the outside skin. We contacted Precision Plumbing and asked them repair it. When the tech discovered it was double wall, he advised that the entire flu, all the way down to the furnace would need to be replaced at a cost of around $500. However, he stated that because only the exterior wall was rusted, we should just double wrap it with Nashua, foil tape for around $20. See photo, looks like it will work
