  1. Pay the extra dollars

    Posted by Rob on 6th May 2015

    After installing ridged insulation on unfinished basement walls with Great Stuff Wall and Floor, I proceeded to tape off the seams with Tyvek tape as you see recommended all over the internet. I even rolled the tape with a wallpaper seam roller to get the best possible bond of the tape to the foam board.

    There was a small section that I decided to re-tape. Expecting the Tyvek tape to be well bonded, I prepared myself to have to pick off little pieces of tape because of a good solid bond. What I found in fact was that the Tyvek tape peeled off very easily. So easily in fact that I found it alarming. The bond was fairly week.

    At that point I decided to go with the recommended JointsealR tape. Yes it was more expensive, but the bond of the Tyvek just didn't cut it for long term sealing of the seams.

    After receiving the JointSealR tape, I proceeded to remove all of the Tyvek tape from the 900 sq ft basement walls. I had every piece of Tyvek Tape removed in 5 minutes time. It just peeled right off.

    The first thing different I noticed about the JointsealR tape, was that it was about twice the width of the Tyvek. Also, the tape itself is very, very, stretchy. The other thing you notice about the JointSealR, is the paper backing it comes on. Once peeling off the paper and applying the JointSealR, you immediately realize just how sticky the glue is. Once the JointSealR tape is applied to the ridged insulation and rolled, it does not come off. The bond is at least twice as strong as the Tyvek tape and maybe even greater.

    The simple truth of the matter is, for sealing ridged foam seams, you cannot even compare the Tyvek tape to the JointsealR tape. One tape is specifically designed for the job, has a superior glue, expands and contracts, and is clearly the correct tape to use for a long lasting job... JointsealR Tape.

    The other tape is a another purpose tape, has inferior glue, is narrower and does not easily expand and contract and is clearly a tape used for a corner cutting, get the job done and save a few bucks job.

    The JointsealR tape is not just overpriced hype. It is the real deal and I highly recommend those that want to do the job right and have it last for decades, instead of a couple of years, buy and use the JointsealR tape. The tape that was obviously designed specifically for the job at hand.


  2. Stickiest Tape Ever

    would be completely shocked if this tape ever thought of falling off


  3. Not 5 Stars Due to Price

    Posted by Jason on 6th Feb 2015

    I installed foam board over the walls of my cinder block basement walls. After install, I read I had to tape the seams to complete the system (avoid moisture / stop drafts). I bought a few rolls of a Tyvek tape which I found didn't stick well and could easily peel off. I found this Jointsealer tape online and was shocked at the price. I bought one roll as an experiment just to see if it was worth it. It came the next day! I opened up the box and at first glance I could tell this was the real deal. The roll has Owens Corning printed every inch and it is almost too sticky. After putting the first strip on, I tried peeling it off which is nearly impossible. I am here to order 3 more rolls now. PS one downside besides the cost is that cutting will seriously gunk up your scissors.
