Aluminum Tape, 2 inch x 65 Feet Foil Tape (3.9 mil), Insulation Adhesive Metal Tape, High Temperature Heavy Duty HVAC Tape, Silver Tape Aluminum Foil Tape for Ductwork, Dryer Vent, HVAC

First roll sent was smashed beyond use. Sent in thin envelope. Replacement was OK after being sent in a padded envelope. The if tape is fine. Good adhesion if surface is cleaned properly. Good workability. Ask if they will send in a box or at minimum a padded envelope. Otherwise you are taking a risk and may have the hassle and wait time for a replacement to be sent out. Id probably buy elsewhere if I need it again.

I used this for connecting new ductwork joints for a dryer exhaust line. Not sure Id call it heavy duty, as the aluminum is thinner than regular heavy duty duct tape, but it adheres well and easily shaped into the nooks and crannies of the connections.

Used this tape to fasten insulation to garage door. Worked perfectly.

Works great love that it lets me get the right amount of tape everytime

Works excellent! Easy to use and definitely strong.

The price was low, but despite it being advertised as being heavy duty(3.9 mil it said), it seems thin and easy to tear. It sounded thick enough, but if that is true (3.9) I would likely order something more like 5 mil. I wouldnt purchase it again due to this issue, but its still an OK value for the price if your needs are for a lighter duty aluminum tape.

Did the job perfectly

Very nice tape for duct work
