ZIP System Huber Stretch Tape | Self-Adhesive Flexible Flashing for Doors-Windows (6" x 20')

I am blown away by this tape. I’ve used bituthene flashings like Vycor in the construction industry for years, and they work well, with some limitations. I needed to seal a waterfall corner in a raised pond with HDPE liner and was absolutely struggling to find a good solution. Supposedly No adhesive works on HDPE and it needs to be heat welded. Well, this stuff sticks incredibly! I was going to use classic bituthene flashing for this, but it is not flexible enough to create a good seal for this outside corner. I discovered this flex tape and I’m sold for life. I cannot believe how thick and flexible it is and how well it sticks throughout the range of movement. I’m confident this seal will hold up for a while. Not so sure about UV damage though…Pretty pricy stuff, but there’s nothing else like it! Amazon was the only place that I could get it, but it arrived far quicker than advertised.

This is my first time using Zip System on a building. The Zip products are great. The stretch tape was unavailable when I needed from my local big box stores. Amazon had it. The product really does work as good as it appears in YouTube videos.

Best product I've used, very plyable stretches in corners perfectly

This Zip tape really does what it's supposed to and I cannot tell you how happy that makes me! I purchased it so I could install a shed window, after watching several YouTube videos. Originally, I had bought regular flashing tape from Home Depot, but I could tell it wasn't going to stay sealed for long. I grew frustrated because it should've been simple and easy, and yet was becoming a problem. So I ordered this Zip tape (sadly, no stores carry it in my small town) and it worked beautifully. It easily stretched around the corners of the window opening and then adhered to the uneven siding seamlessly. Given the resiliency and adhesion of this tape, I feel confident it will keep the area waterproofed through many winters. This product is well worth the price and I can't recommend it enough!

... or use with caution. Because it stretches it wants to displace the house wrap. You probably all already thought of this though. I think we've made it work anyway but only because the project is so small.

5 year review.This is the best peel and stick I have ever seen let alone use.IF properly installed, it will stay put and do the job as advertised.Excellent, even if a little pricey.

I was always buying the Dupont Flexwrap so I went to order it again. It was just what I saw all the pros on YouTube using so that's what I wanted to use to do it right. I have Installed about 30 windows and have always used that stuff. I never liked the way it left the bulge in the corners but it worked and seemed to seal pretty well. Went to install a few more windows and ordered the Flexwrap from a seller on Amazon. Received the wrong product in the correct box. Not sure who was at fault for that but I couldn't find any more at a good price so I researched. I guess this stuff got pretty big after I first saw the other stuff in videos. Ordered this after watching a few videos and I'm glad I did. This stuff is great. There is barely a bulge in the corners and it seems even more sticky. Will definitely be using this from now on. So it was a happy accident that I got the wrong stuff before. It goes on very easily and it's very sticky. It's not super thick and hard to manage, it's the perfect balance and seems like it will hold up very well.

This product is amazing. Best tape I have found for sealing windows and doors on the outside when preparing for a storm.It peels off without removing paint or leaving a residue. Only con is you need to put it on a very dry area, if it gets wet before you put it on it wont stick well even if slightly damp. But it sure sticks and seals if dry!It's expensive but exceptional. It's my storm go to product.
