Kimberly Clark Block It flashing tape – Any experience?

Smc1900 | Posted in Energy Efficiency and Durability on

I’m trying to source reasonably priced materials for a new build. I came across what looks like an amazing deal on the butyl flashing tape above (less than $10 per roll for 6″x75′). Its from a well known company, but I would never have associated them with building supplies. Wondering if anyone has ever used this for flashing windows and doors?

    The manufacturer's website is underwhelming -- not much information, which is never a good sign.

    Customer Service sent me a link to more information - looks like their website is not easily navigated!

    I placed an order - comes in a pack of 6 - 6"x75', less than $10 per roll. It's probably going to arrive too late for me to use around my windows (I have 3m 8067 coming for that), however I may be able to use it elsewhere, and I do plan a simple 'backyard' test to compare to some others.

    I have found the Tite Seal brand of butyl flashing tape to stick extremely well to OSB and Zip and it is reasonably priced(not as reasonable as the KC!)
