Customer Reviews for Nashua Tape 2.5 in. x 60 yd. 324A Premium Foil HVAC UL Listed Sealer Duct Tape

This one was purchased for the sealing of my HVAC system. The adhesion strength is adequate. However, I encountered several long areas that totally lacked adhesive on the foil side. I believe I purchased the faulty item. Can I get a refund in this case?

I used this tape to seal beetween our gutter and flashing that created a cap that would allow water into our roofline when the gutters would get overloaded. Still need to drop a new downspout in the gutter but this sealed the water out of the house!

Nashua foil tapes have always been my 'go-to' tapes for HVAC related work or other sheet metal related sealing and repair tasks. It is described as a 'premium foil' tape because it is superior to all other foil tape product I've ever used. The 2.5" width is great for sealing a seam and gives you plenty of left-over to create a very sturdy air-tight seal on the metal or flexible ducting HVAC parts. 60 yards goes a long way and ensures that you are not running through multiple smaller rolls which create more waste and increase costs. The tape cuts very easily with scissors or a utility knife and the paper backing is always easy to remove when ready to apply. Years after install, even in heavy condensation conditions - I find that the tape I have installed is still holding long and strong. For your safety and comfort, it is a Low VOC product and Made in the USA of US and global components. It handles a huge variety of temperatures but if you need a more extreme tape, Nashua has one and Home Depot sells it - described as Extreme Weather. The versatility of this tape is great and it is well worth the premium you pay for it.

This premium foil tape works as advertised and is easy to use. I will use this premium foil tape for my future HVAC projects.

Tape is NOT well made. Foil comes off in random patterns leaving bare adhesive and clear tape. Was able to wrap it around enough to make the two joints i had to seal stick but its ugly. Tape is essentially unusable

Great for sealing foam insulation to protect against freeze damage

The tape around my duct work on the on the AC unit was almost complete loose. This Premium Foil Tape was very effective in sealing the old tape to the duct. I applied it about a month ago and so far it is holding well. Caution: when you peel the back off the adhesive, your tape will quickly coil into a loop and stick together. Be sure to hold both ends when removing the backing. Since I was working alone, I would remove a few inches of the tape, stick the exposed end to a stud or duct, and then finish removing the backing.

As a DIY every ten to twelve weeks I 'service' my A/C Air Handler-Furnace. I first shut off the electrical and remove the air handler panel cover. I then inspect the evaporator “A” coils for debris accumulation and drop anti-algae tablets in the condensation pan to keep the condensate line free of blockages and potential overflow, water damage. This whole process only takes approximately ten minutes. After putting the air handler panel cover back on I tape the entire seams, between the cover and handler body with Nashua 324A Premium Aluminum Foil Tape. It not only provides an airtight seal to keep out leaking 'by-pass air' drawn into the handler, but is also provides a vapor barrier to keep moisture out. Sealing my air handler with Nashua 324A has saved me money over the long run through increased efficiency from not having to cool and dehumidify leaking air drawn into the handler. This has also kept the air handler fan and evaporator cooling coil cleaner too. Most of my friends are shocked when they see how 'leaky' their air handler-furnace is especially if they have to remove the cover frequently to change their air filters. The screws holding the cover on get worn and don't seal the unit. Nashua 324A Aluminum Foil Tape is what I recommend to them to properly seal their units. At first they balk at the cost of the tape over cheap duct tape, but there is no comparison. Cheap duct tape just does not hold up to after being exposed to moisture and temperature fluctuations, which is why I recommend this Nashua Foil Tape. Besides, it is UL listed for the very purpose of sealing HVAC equipment.

Worked perfectly to close a hole in the ceiling as well as the space around the water heater exhaust pipe through the ceiling.

I used this to join car window heat shields that were also silver & bright . I made reflective window shades to help reflect sun rays & make cooling my upstairs more efficient. Worked great!!!

good product and easy to use for our repair job at home

I got this tape for my HVAC and the smell is really bad. Is mine bad or it’s normal for it to smell like that? I will probably throw it out

This duct tape is UL-approved and adheres firmly to the ductwork, making a solid, lasting seal. Even the tiniest amount of (cold or hot) air leaking from ductwork in the attic or crawl space is money going to waste. This tape sticks, seals, and remains that way and that is what counts!

Works fine, so far, for sealing the seams of a sauna vapor barrier.

Great adhesion and easy to work with.

3 days after installing on metal duct work in the crawl space it started peeling off the ducting. The ducting and connector surface was prepped/cleaned prior to install now that I look back I’m sure scotch tape from the office would have lasted longer than this tape. Buyer beware your going to waste time and money with this on ductwork.

Absolutely works as advertised. Easy to cut, adhesive works very well as long as the surface is clean and free of dust. I easily worked it into 90 degree corners. This foil tape is way better than the duct tape I had applied a few years ago.

Great. Worked as advertised

It’s the only aluminum tape anyone should buy

Product was exactly as described and performed how its suppose to.

This tape did not stick very well. Difficult to work with

Sides are not sticking to silver insulation yet expensive.

Very sticky and easy to use. Great for insulation!
