Has anyone used the Green Girt system by Smart CI Systems yet? It is a composite Z furring solution that eliminates the thermal bridging. I’ve been in the lunch presentations, etc. but have yet to specify it on a project.
Russ,
This girt system is new to me. Thanks for sharing.
While it appears to be a reasonable alternative to galvanized steel girts, we prefer to use clip and rail systems that allow for adjustment to tolerances inherent in the substrates encountered. Every substrate is not plumb and flush with interfacing structures. KnightWall, Cascadia Clip, Nvelope are our preferred choices. For information on Nvelope go to http://www.interra-facade.com/nvelope-rainscreen-systems
Compliance with NFPA 285 is conspicuously absent on the website.
At this time the videos will not start. I receive the message “The video cannot be shown at the moment. Please try again later.”

Wayne - the NFPA 285 compliance is indicated on the brochures they gave us at the lunch presentation. Seems like an important thing to have on a website.
We were actually looking at using this behind face brick. They claim it can replace the air and moisture barrier and eliminate layers and therefore save labor. The tolerance thing has me concerned - so we will dig some more.
I think the clip and rail are labor intense ways to fix someone else’s problem. The framing should be within specification. If it’s not then have the framer fix it. A standard galv zee furring should sufffice if it’s thermally broken. The green girt is basically the same as the zee as it has metal reinforcing to give it pullout capacity for fasteners. Lot of bells and whistles that don’t really have much effect except to “dazzle”.
Armatherm also has a non-metalic girt system that you may want to investigate.
Green Girt’s SmartCI seems like a good option for continuous insulation. Looks like we may be getting it on our first project.
I’m interested in Cascadia Clips from Cascadia Windows and Doors - http://www.cascadiawindows.com/products/cascadia-clip. They have shapes that can take z-furring or hat channels and still support the veneer if the clips melt away, unlike the Smart CI.
Just saw it for the first time a couple weeks ago. Pretty cool product.
We had Green Girt Smart CI included as a bid alternate on a recent project, but it never left the ground.
Ken,
I prefer the Nvelope NV1 vertical rainscreen cladding support system.
My local Cascadia clip rep dropped Cascadia in favor of the Nvelope NV1. NV1 handles out of plumb substrates easier and will less labor.
Labor intensity was the bag knock on Cascadia clips in my region.
Please go to http://www.nvelope.com/cladding-systems-NV1-vertical-cladding.html for more information.
My local rep is David Sommer at 206-226-2311. Dave has projects all over the country and Canada.

Tell him Wayne Y. sent you.
Thanks Wayne. I’ll check it out.
Have Green Girt on a current project for terra cotta areas; should see drawings soon. I’ve had Cascadia on a few projects dating back 5 years or so. All projects feature(d) mineral wool cavity insulation and all-inclusive delegated design (including studs).
For your awareness, I’ve also seen perforated “swiss cheese” steel clips proposed as an alternate to fiber reinforced polymers. Difficult if not an exercise in futility to evaluate all the options, including the tried and true double-angle adjustable “zee”.
Wayne thanks for reminding me of the NV1 system.
Wayne,
Is “bag knock” a Canadian thing?
David,
I do not know this term.

From what I have heard this system is pretty expensive. The CI has to be shipped to their plant and specially cut for all the notches to fit. It is NFPA 285 complaint, but as far as I know it does not have any testing reports (DRJ or ICC), which is a negative for me. A co-worker showed me the Cascadia Window clips the other day. It looks pretty cool and also much cheaper. Haven’t specified it yet though, so can’t say much on it though.
