[Sprinklerforum] Re: Residential Layouts

To piggyback on what Ken says, if you have to do the interstitial spaces and if the top chord of the floor truss is >4”, per the listing of the interstitial sprinklers, you are not able to use CPVC piping. At least that is what I found with Viking and Tyco. I assume they are all similar.

[Sprinklerforum] Re: Residential Layouts

Brian, That's part of the good information needed, as Taylor previously noted. Here's a few thoughts: * Are you protecting per -13?  If so this may be a combustible concealed space and require sprinkler protection. * Is the ceiling attached to the bottom of the truss?  If so, this is a

A lot easier to get pipe through there. Just coordinate with other trades about elevations and installation dates if you're running horizontal. Don't let other trades install their incompatible products touching your CPVC. Taylor Schumacher Security Fire Sprinkler 1

[Sprinklerforum] Re: Residential Layouts

Birdcage has less pipe, but you will have to drill, fire caulk and nail plate each floor. You'll have to decide which is cheaper for your field staff to perform. You didn't mention which standard you're in, but if it is 13, you'll have to zone each floor separately anyways while the upper

[Sprinklerforum] Re: Residential Layouts

Brian, You did not detail the installation standard or pipe material in your email, but I thought I would add that if you are protecting using NFPA 13 and require concealed combustible space protection while using CPVC pipe and employing the "bird cage" system, there is has been a change earlier

Thank you Craig, That is perfect. I was conveying this issue to the builder and his response was “I have no idea”. Not very helpful… Chris Dorn From: Craig Hanson Sent: Friday, June 30, 2023 9:57 AM To: Discussion list on issues relating to automatic fire sprinklers Subject:

Chris here is my comment I use when dealing with your situation: *Protection Against Freezing- *These are areas that are subject to freezing and require that the piping be protected by either direct heating, heat trace, dry system or anti-freeze [NFPA 13R 6.7.2.1*]. Although it is the owner’s

[Sprinklerforum] Re: Residential Layouts

Interested to see the responses as I'm dealing with this same question. Also when the building has breezeways instead of corridors how do you get from one block of units to the other without having piping in an unheated area? Thanks, Chris Dorn From: Brian Harris Sent: Friday, June 30, 2023

[Sprinklerforum] Re: Residential Layouts

It really depends on the project. For the basic wood frame 3-4 story project, I run mains and lines for the lower level and rise up in the walls for the top floor. That way can avoid dealing with an ungrateful attic. If you have to zone each floor, that changes

I do a residential/apartment project about once every couple years so each time it's like starting from scratch. For you guys that do these a lot which way is preferred; running mains and branchlines in joist with pendent heads on the first floor and then "bird cage" vertically with sidewalls
