Nashua324A/SI2560 324A Cold Weather Premium Foil Tape, 4.8 mil Thick, 60 yd. Length x 2-1/2" Width, Silver

We used this to support the havelock wool we are installing in our Skoolie.

I live in a condo. The dryer vent goes out to the ceiling in my unit. After 8 years, the hose got loose and the clothes were not dried anymore. The tape used on the hose was Nashua 324A. After received the tape from Amazon, I cleaned the vents and hoses in reach. I used a vacuum to suck the lint out. The dryer worked great after I took out tons of lint. I gave the tape away and needed another one to re-tape the hose connected to the vent to the ceiling. It's a big roll of tape and I wouldn't give it away this time. My neighbor used it to tape a box.

I had used duct tape to connect my dryer to the exhaust vent, which quickly dried leaking moist exhaust into my laundry space. I read an article in Fine Homebuilding which suggested using mastic tape, but had difficulty finding it locally. This tape arrived quickly, and worked great. My only observation is that I did not pay attention to the length of the roll, so I now have a lifetime supply ... enough for myself and everyone I know and may ever meet!

Just love this stuff! Used it throughout my house to seal the seams during construction. Now, I have lower energy bills than my neighbors (because they are losing air). Used it on my direct vent natural gas fireplace too! Really sticks and the aluminum is much thicker than other brands. You get what you pay for.

I use this for Fixing a leak in my Duct . It works perfectly
