RE: Wall Wetting per IBC - 2012, Chapter 31, 3104.5 Exception 1

Scott (and others), I agree with you that this is not a matter of “actually” providing any equivalent fire protection to a 2 hr wall. This is checking the box on a Code requirement. That being said, I don’t see this provision significantly reducing the hazard of a fully sprinklered skywalk

Might want to also take a look at FM Global Data Sheet 1-20 “Protection Against Exterior Fire Exposure” which talks about this issue. Passive protection to accomplish required or desired separations are typically the preferred first choice such as fire rated partitions or walls but in cases

David, I’ll stand by what I wrote, to the best of my knowledge there hasn’t been testing to prove sprinklers as an effective strategy or an equivalency for rated construction. Window sprinklers for glazing are the exception, but to use a ‘water curtain’ in any manner in lieu of a required

Bingo, but architects in general don’t care if it is ‘completely’ wetted, they are just looking at the method… I’ve argued until I’m blue in the face that they can’t wet the entire surface with standard sprinklers at the ceiling above… Scott Office: (763) 425-1001 x 2 Cell: (612) 759-5556

Re: 13D Porches

I suspect the equivalency would be valid but I have not actually opened the CFC for its exact wording, I’ll leave further comment on it to those applying it. Nonetheless, lets transition to the IBC and 13R. Unless the local adoption deletes the portions of chap 9 that exceeds 13R requirements

You’re dealing with exposure protection between and one bldg. being considered the “Exposed Bldg” and the other the “Exposing Bldg” using a water curtain. NFPA 13, 2013 7.8. These are sometimes designed as open head deluge systems to create the curtain effect to provide separation. Depending

Re: 13D Porches

I'm a little confused by that too, Mark, since the CFC (California has to have their own, you see), clearly makes reference to NFPA 13D being an acceptable equivalent to the guidelines presented in the CFC. It would seem the design could follow 13D, and still be in conformance with the CRC (or

RE: 13D Porches

Just for my benefit, if the building is a single family residence, and 13D is the design standard, wouldn’t the locally adopted building code need to recognize some form of the IRC, and not so much the IBC for this application? Mark at Aero 602 820-7894 From: Sprinklerforum

RE: 13D Porches

No, no that's not the spirit of my comment. I just chose yours for response because it was the most recent but the implication was that this is being over thought. The question perhaps should be, "Is a screen porch a room?"Is "Porch" a defined term in the IRC or the sprinkler standard?

RE: Wall Wetting per IBC - 2012, Chapter 31, 3104.5 Exception 1

I will note we don’t even have glazing in the walls in question. On a previous job at a community college for an after the install wall upgrade, we used Firelite in the entry doors where we couldn’t get sprinklers to work, window sprinklers where we have glazing and “closely spaced” sprinklers

You're getting there Grasshopper. The Truth lies in the Relative Roughness. Meaning slightly corroded small pipe suffers far more friction loss relative to the square of the velocity than slightly corroded big pipe. Come and get me Roland. You are the King of the Hill now. I'm ready for whatever

Re: Wall Wetting per IBC - 2012, Chapter 31, 3104.5 Exception 1

look at NFPA 13:8.15.26 - Sprinkler Protected Glazing. The wetting of the entire surface is rather important (in order to avoid failure of the glazing (barrier) from thermal shock. It, I believe, originated in the Life Safety Code (which long ago allowed an exception using sprinklers with

RE: 13D Porches

What am I missing here?The question is whether 13D (that's "Thirteen Dee") requires sprinklers in porches and we've got a thread that's turning toward the IBC. If the dwelling(s) in question are being built per the IBC then I don't think 13D would be the correct standard in the first

actually it is not a fixed velocity where results diverge. It differs based on diameter and type of material (coefficient of roughness). Sometimes HW shows a greater loss and others DW. Roland Roland Huggins, PE - VP Engineering American Fire Sprinkler Assn. --- Fire Sprinklers
