I'm living in an apartment where the property managers don't like to take care of their tenant's maintenance problems, and when they finally give in and make the attempt, they fall short of doing any sort of quality work. Last year, to patch up several jetting air leaks in the HVAC duct work, they used normal duct tape--which melted soon there after. Melted!

I've been in stores looking for the right kind of duct tape, but no-one who worked at any of the large home improvement chains could tell me anything about the duct tapes they carried. Nothing of value, so I had been reluctant until I had the grand idea of reading reviews of duct tapes online, which brought me to trying out this tape.

First of all, the tape is very, very easy to work with. There is a thin plastic backing that lets you handle the tape and cut it to the correct size without it sticking all over everything and losing its adhesiveness in the process. Once you're ready, you can peel a bit of the backing away and anchor the tape, then steadily peel the rest away as you apply the rest, exactly where you want it to go.

The air pressure behind the leaks is so high that it literally tore off the duct tape that was applied last year, but so far (about 3 weeks now), this foil tape has held on tight without even a slight bulge where the air leaks have been sealed. I've run the air conditioner in the day and the heater at night (desert conditions in spring--cold nights hot days), and there has been no warping or melting of any kind.

A couple of the air leaks are occurring where the duct work "meets" the HVAC unit. I put that in quotations because the "meeting" is offset by several centimeters, making it impossible to create a seal.

This is great tape. I bought it to repair a heating vent and have found it useful for other projects as well. I'm going to buy more of this same tape.

I taped my 4" ductwork and it seemed to increase my dust collector suction by 50%. A lot of suction is lost at the pipe joints. Highly recommended for your dust collection system.

I got this 50 yard roll from Amazon for about what I paid for a 10 yard roll at the local home improvement store. Definitely a great deal. It is very pliable, extremely sticky, and works great. I took one star off because it is not as strong as that other roll. If you are forming it around corners or uneven seams, this roll is far more prone to ripping, even if the sheet metal isn't sharp. I just had to make a bunch of small patches to cover areas where it ripped.

I bought this tape after seeing it used on some HGTV shows for sealing leaks in duct work (which I have quite a few). Like noob to HVAC repairs, I used duct tape before and wondered why it did not stick for very long! This tape works extremely well at sealing leaks and has not even appeared to budge with the air pressure from underneath. Already I have notice a slight increase in airflow because of using this tape. It is expensive, but I feel worth the investment to save in energy costs for a long time.

I had bought this about 2.5 years ago in case I needed it. Tonight 11pm, I needed it.

My upstairs central air suddenly smelled of plastic, so--with the A/C turned off, and my wife on standby at the thermostat--I headed up the attic with a fire extinguisher. I didn't smell any burnt plastic in the attic even after she turned the A/C back on, but the upstairs bedrooms still did, so I figured the problem was with the A/C or the ducts.

I found that the attic A/C air intake and various housing components' tape covers were flapping about. I removed the original foil insulation tapes, wiped down the surfaces with paper towel dabbed in rubbing alcohol, then applied this foil tape to cover the openings. I also took the opportunity to tape up various holes and rips in the foil ducts, which ended up taking almost an hour.

Afterwards, I had my wife turn on the A/C, and voila, no more funky smell. I've hopefully also improved the A/C efficiency ever so slightly with the hole patches.

I got this to cover the cheap wires on deer feeder solar panels that were falling apart from UV degradation. I've got about 20 feeders and just keeping them running is a pain. wrapped the wires where unsupported, or taped the wires directly to the feeder body where I could. Adhesive is strong, foil is flat and malleable. If you want to protect wire from UV, this stuff is great. By the way, if you're using solar panels on deer feeders, consider installing diodes on the positive side of the panel to keep the battery from discharging at night.

I bought this foil tape to do some duct repair on my HVAC system. It seals the ducts perfectly and is very easy to apply. The foil tape is paper backed, so all you have to do is peel off the backing and apply. A Great product!
