Fixman 190288 Aluminium Foil Tape 50 mm x 45m

Does what it says on the tin, as long as you're applying it correctly and putting sufficient pressure the adhesion is pretty good. Been running my aircon for a few ours now and the tape I've coated the exhaust area is holding up way better than any duct tapes or other crap I've tried. Kinda thin but if you're careful it'll get it done. I used a few extra layers to be sure. Pretty happy, will buy again once this runs out. Only feedback would be to make a easier way to remove backing, for example the two half thing that a lot of adhesives have.

Goes a long way and a good price, a little thinner than some other brands , so it tears more easily, it's also more difficult to separate the backing paper with damaging the foil, but it sticks well and does the job.

Yes, it is thin, like others have said. But it is tinfoil, so no surprise there, is it? Key is: it peels off rather easily, yet is VERY adhesive, and it DOES stick in rain, which is necessary for outdoor application. While that it's thin it can rip easily IF you tear it, if you don't, it won't. And, the thinness provides for perfectly tight adhesion in places with flowing water. So, absolutely recommended, this tape!

This was great for holding the lining on my shed.

Used 50 rolls to seal up PIR insulation in a roof and walls. Quite thin and easily teared but, within a few minutes you will be applying it smoothly while removing the backing tape. I would use stronger tape like cheaper DPM tape for the ridge and eaves joins to ensure air tightness but this stuff is plenty good enough for walls/roof. Just make sure you remove any dust from the surface you are sticking to with a cloth.

I've insulated a large shed with foam insulation and used many rolls of aluminium tape. This is by far the flimsiest I've used. I had previously purchased two rolls of the same tape, but this latest version is very thin. It does adhere well and moulds to shapes but pierces too easily.

Nice wide size allows for more coverage, however the material is very thin so you can quite easily tear this in use therefore you need to make sure the area you're using it on is not likely to be moving or being struck by things as it will tear. I've used this to joint some insulation foil rolls in the garage. I've found this item to be more adhesive than some other brands but the fact it is very thin means you need to be careful to avoid this wrapping around on itself which happened a few times.

Ery useful tape. I sealed all joints on my foil coated insulation boards and attached them to the up and over garage door. Also used for scale modelling to recreate aluminium finish it finds and follows the ridges and dips nicely. Also for airsoft useful shimming parts for exact fit. Its very stick backing doesn't make it any thicker and it really stick to clean surfaces. It's very useful. Can be tough to separate from backing but once mastered it's quick. Best applied as you remove backing otherwise it twists and easily stuck to itself. You soon master the technique. It's tough too. No complaints and reccommend.
