6 months long, adhered, rhino and ballast

One of those new construction jobs that seemed to never end, with a lot of different detail and system types. A Sarnafil job with Adhered, Ballast and Rhino-Bonding.

A lot of pics, most aren't all that informative to roofers. Descriptions are meant for customer reading, but you can wade through them pretty quick for anything of interest. Job is just wrapping up.

I see it applied a lot in retrofitting metal roofs around .since the purlins are 5' apart a mechanically attached system with carlisles 6' wide rolls anchored to the purlins is a safer system IMHO than this one .

Ya know, we jumped back into the single-ply game after 20-years away from it. We pretty much had to or risk letting another roofer have a shot at a good customer of ours. We just finished that 300 SQR TPO job and it reminded me why we don't like single-ply.

We spent 5 weeks on the job. We made $40,000 "less" profit on it than we made on the silicone coating job we just did that took 8 days.

Our nearly new Leister Uniroof and 3 hand welders will be sold.

Vaa Fakaosifolau Said: Do you have a Web link that shows those tests Alba? https://www.omgroofing.com/productivity-tools/omg-rhinobond.html?language=en& It's under the test lab video. as you can see the weld to the plate bears the brunt of the wind load pressure not the plate itself and the strength of the membrane's polyester fabric isn't utilized .At some point fatigue cracks will be created around the plates and or the weld will come apart. This kind of system isn't conducive to the size of the roofs that you put on anyway .

After having seen how the rhinobond system behaves under the wind load tests ,I have a gut feeling that the construction law attorneys will get very rich by litigating its manufacturer and or installers.

twill59 Said: Advanced attachment of TPO and PVC Roof Systems OMG RhinoBond is a superior attachment system for TPO and PVC membranes based on patented electromagnetic induction welding technology. The system uses the same fastener and plate to secure both the insulation and the membrane to the deck without penetrating the roofing material. The result is a Factory Mutual-approved system that does not create any point of entry for moisture, requires fewer fasteners and provides superior wind uplift performance.

PATENT NOTICE: The OMG RhinoBond® Electromagnetic Induction Tool is covered by U.S. Patent No. 8,492,683

Features & Benefits RhinoBond typically uses 25% to 50% fewer fasteners when compared to traditional mechanical fastening methods. Up to 30% fewer seams versus traditional fastener methods. RhinoBond does not require 1/2 sheets for perimeter fastening. Zero penetrations of the roof cover. Approved for use by most roofing system manufacturers.

I knew you could do it. :)

Now I hope that doesn't piss off Tom B who scoffs at anything found on the internet. I'll just let you fellas play. I've got better things to do :laugh:

Right Tim

twill59 Said: I cant figure out....What exactly is the Rhino Bond?

It is a new shingle design that uses a siliconized adhesive strip that - in theory - will bond the shingles together at temps as low as 25 degrees.

I can't figure out....What exactly is the Rhino Bond?

Tim,

Thanks. I do, and we do a lot of it.

Mike, They are. I'm not sure what you mean by "low slope"? The shingles are part of the existing building, and we are tying the two sections together where you see shingles. We are just going up high enough to provide adequate flashing height, then under a row and finished with a counter flashing. I think any of your PVC membranes will get those "buckles". 1/4" per foot deck slope, 1/2" per foot saddles, there's enough variation in slopes to cause a little twisting in the membrane if you're going to keep your laps straight. All but the ones around the drains will be gone it 2 years or less.

John, From the other thread.... "Damn Mike, 6 months on that roof so far. How big is it? Is that a completely new plant? Why a loose laid system with ballast? Just curious."

Not sure about the "3 guys standing". I assume that's a reference to Tim's drone thread, misplaced here.?.?

I forget the total size off hand. It's not that big, maybe 3-4 hundred squares total, but it's a chopped up and complex, multi-story addition, in a crowded campus, on a building that remained fully operational. The ballast section was a concrete deck, originally slated for a fully adhered system, but construction delays pushed it into weather too cold for adhered by the time it was ready for roof, so they took the ballasted route to avoid further delays.

I guess I wasn't the only one that saw the three guys standing eh?

Very nice! How do you like the Rhino Bond system?
