WTF WRB testing - Round 3: Huber ZIP and GP ForceField

- How do these integrated WRB/structural sheathing systems handle water held in tension? The simple Wingnut test shows good results for both ZIP and Force Field!

Would love to see LP Smart Siding done this way as well to compare. Also, would have included a piece of regular OSB as a control piece.
thank you for doing the video. i wonder how it would compare to felt paper
comparison good. a third control sample would put weight gains into context, to see weight gain in non-coated OSB, as data point. thank you good comparison.
I'm concerned that the metal flashing is wider than the sheathing piece, as shown at 4:30 where the metal piece extends far beyond the sides of the sheathing pieces. The water that enters between the metal and coated sheathing will spread out between the metal and coating until it reaches the side of the sheathing. At that point, it may wick in around the coated surface into the side of the sheathing. In a proper installation of either material, the side of the sheathing wouldn't be exposed in this way.
That is a good point and a prime example of why we need more wingnuts improving testing. In this case, I did take several pin-type moisture readings for each sample, being sure to look for consistently elevated readings near the vertical unprotected edges, and did not observe any. But it would be better and more convincing if I improved the test to more clearly protect those edges, maybe wrapping them with tape as well and cutting the flashing down to not extend past the samples. Thanks!
1/1000 of a pound.... Can we just use grams please?
Sorry about that; will try and include both I-P and metric units in the future...
@@peteryost7876 No offense meant. It just felt like an absurd amount for those units even to this American.
These videos would be more useful if you spent less time on your methods and more time on the results. I still don't know if forcefield is an adiquet substitute for zip system and that's what most people want to know when clicking on this video. Just my opinion... I'll look at some of your other videos, maybe the answer is there.
the guy who invented zip also made the forcefield, so they are about the same. czcams.com/video/hWYjP-aerzI/video.html
I don't understand why builders cut so many corners to save money. Why not paint the edges of the sheathing, or paint the whole sheathing? Or why not design the sheathing so that moisture runs down-slope, with tiny ridges. Or just add more zip-tape.
Because they don't have to live with it when it fails. Lack of quality control. Lack of pride for your community. Etc....
There is a cost to everything. Sheathing in and of itself is very rarely the failure point of concern in new housing. The fact of the matter is that homeowners simply will not pay for for a framer to paint the cut edges of osb or take time consuming steps to add minimal extra water resistance. A good builder will take the extra time and effort to build up water resistance around areas such as penetrations or deck ledgers etc. Overall it’s a balance of giving the customers what they want and what they actually need.
@@benjamindeboer6920maybe they would if they knew the benefits of it, and maybe builders framers should offer these options, but in all reality many people don’t really care that want it fast and cheap as possible.
I'm pretty sure Force field has a laminated film but isn't zip applied as a liquid like paint? Zip tape is a robust many usage tape that can be applied to rough surfaces like plywood or raw OSB, or for bridging between sheathing and wood. Force Field is a thin smooth non stretchy tape and can only be used on the Force Field sheathing. That brings up another issue. Zip sheathing has a rough texture that Huber claims will allow water to escape under external foam insulation. I can't imagine the smooth Force Field can do the same. Therefore, a draining house wrap will would be required between Force field sheathing and the foam. I've heard that the same person designed both systems. It is clear to me that Force Field was developed mostly to skirt Huber's patents.
Personally, I use neither system. I simply don't like OSB. I sheath with plywood, Tape the seams with Zip tape, and use draining house wrap for the WRB.
Forcefield does have a premium tape that is yellow. It's rubbery and very high adhesion. For the price difference the forcefield system is pretty great in my opinion.
This is really interesting... do you have any tattoos?
Can you stop repeating everything you say like 20 times. This 8 min video could have been 3 min long.. an Interesting subject semi-delivered by someone with no presentation skills at all. No clear conclusions or winner product...
So where are YOUR You Tube videos so we can CRITICIZE YOUR PRESENTATION SKILLS OR LACK THEREOF?
