GGR SuppliesAF-20R Professional/Industrial Grade High Temperature Heat Shield Resistant Aluminum Foil Tape Ideal for HVAC, Air Ducts Repair & More(3.6Mil): 3 in. Wide x 50 yds.

I used this tape probably not what’s it’s intended use is but, it worked wonderful! Better than duct tape. I have a large window ac that I use in my gaming room and there is a very large window in the room that slides open sideways. Very difficult to setup a window ac in without a lot of areas that leak to the outside. The area I live in gets 110-115F in the summer June-October essentially. I had setup the window the best I could with duct tape but the tape didn’t stand up to the heat, well my room got too 104 one day while I was at work since the tape just fell off the window and all the reflectix came off and the black out curtains don’t do much when there is gaps however small they may be. I got home and had alarms going off on my server rack telling me they had turned off due to overheating. I run a medium sized tournament server and a few other misc servers for games and I actually make money off of it. When they are down I actually LOSE money due to my contracts. So I went on Amazon to find a strong heat resistant tape and saw this!I got it obviously and put everything back up and added some foam window seal etc. it’s been a year so far! Never needed to use the other bit of the roll! It’s on there and it’s not coming down at all. Not even the slightest! If your use case is similar to mine don’t hesitate to buy it. It really works! I’m also not sponsored by these people, they didn’t give me anything for this review I just am really happy about the product. It literally is saving me money now lol!The only down side is that it can be a bit tricky getting the bottom off so you can use the tape. There is a bit of wax paper or paper under the adhesive you need to remove and it can be annoying to get off. Other than that it’s tape but better lol

Very sticky, heats up nice.

I recommend

If you don't want to spent hundreds of dollars to buy a new underhood insulation this tape will solve you problem. I was be able to taped all the cracks and holes falling apart from the insulation under the hood of my car. So far so good, it seemed to be working. Anyway, I don't know how long will last but I will let you know when the tape start to fall down.

this tape was exactly what I was looking for. it's strong,doesn't tear, and easily comes off the roll. I used it to seal pressed flowers between two pieces of acrylic.

Good adhesion,easy application

Great product

Everybody needs velcro, duct tape and this stuff! Thats it!
