Förch 8844750 Stemkleber Tape System Adhesive Tape, Green

Compared with competitive better known brands of air tightness tape of which I have used dozens of rolls having built two properties to Passivhaus standards, this is just as good as all and better than some twice the price.Very impressed with the strength and adhesion.For those of you who have never used this type of adhesive tape and think Duct tape has good adhesion then buy a roll you will be astonished as to how sticky this is!

Tricky, sticky, stuff. Once it goes on, it isn't coming off. Leave the edge packing on when you use it, otherwise it sticks to anything you lay it on ... Best used for tears and corners, keep the cheaper stuff for large seams. Recommended

Having insulated my ManCave I put up a vapour barrier and used this tape to seal all edges. Super sticky and seals well. Recommended.

Great strong tape used for sealing window frames to scrappy masonry. Great bond as long as substrate is well dusted. Tape is strong and trying to peel off is difficult once stuck down, so I suspect it has a good lifetime. My only con is that it is a shame they don't do a nice wide one for dealing with cavities in one hit.

Airtight. Strong. Best I've tried so far

Really great tape that sticks to everything.

It's wasn't as big as advertised and had few holes where it had been folded before rolled. Had to make do with it as holding job up, but very disappointed.
