NFPA Standards Download National Fire Protection Standards. Find on the ANSI Webstor NFPA 13, Standard for the Installation of Sprinkler Systems, does not have definitive guidance on automatic sprinkler installation requirements for these ceilings and in some conditions requires sprinklers at both the structural ceiling and cloud ceiling panel elevations. Recent NFPA 13 change proposals were rejected based on a lack of. cloud ceilings can vary greatly in terms of the shape and size of the panels, the gaps between panels, and the spacing between the panels and the structural ceiling. The use of cloud ceilings presents challenges for sprinkler protection that are not definitively addressed in NFPA 13

The first question many have is whether NFPA 13 defines cloud ceilings. If referencing the 2016 edition or later, the answer is yes. Cloud ceilings are now defined as any ceiling system, not including sloped ceilings, installed in the same plane with horizontal openings to the structure above on all sides NFPA 13, Standard for the Installation of Sprinkler Systems, does not have definitive guidance on automatic sprinkler installation requirements for these ceilings and in some conditions requires sprinklers at both the structural ceiling and cloud ceiling panel elev ations. Recent NFPA 13 change proposals were rejected base Ceilings must be of smooth construction (NFPA 13-2016 8.15.24.2.4) For irregular shaped (non-rectangular) ceilings, the minimum ceiling width dimension is the smallest dimension of the cloud and the gap width dimension must be the greatest between clouds or walls (NFPA 13-2016 8.15.24.2.5) Ceiling Spacing Calculato sprinklers may be omitted above cloud ceilings. These spaces are likely to follow the same line of thinking for rules and should be included in the new chapter.

  1. Matt Klaus, a senior fire protection engineer at NFPA, clarified the NFPA 13 obstruction requirements that apply to cloud ceilings in his column in the July/August 2012 NFPA Journal. NFPA 13 requires sprinklers to be located within 12 in. (30 cm) of the ceiling to ensure that sprinklers will operate once the gas layer develops at the ceiling.
  2. Cloud Ceilings: Calculate Above or Below Only? When there's a cloud ceiling that requires sprinklers above and below, how does that play out in the hydraulic calculations? NFPA 13 23.4.4.5 implies that we should only include the upright heads at the ceiling and exclude the pendants in the floating clouds from the remote area calculations
  3. Cloud Ceiling Definition 3.3.5 Ceiling Types. 3.3.5.1 Cloud Ceiling. Any ceiling system installed in the same plane with horizontal openings to the structure above on all sides. This does not include sloped ceilings as defined in 3.3.5.4. 3.3.5.2 Flat Ceiling. A continuous ceiling in a single plane. 3.3.5.2 3 Horizontal Ceiling. A ceiling with.

Although proposals were submitted to the NFPA 13 Technical Committee in the 2010 and 2013 edition revision cycles to allow sprinklers to be installed only below cloud ceilings when the gaps between the clouds were small (8 in. or less), the proposals were rejected based on a lack of validation of the computational fluid dynamics model used •Understand the NFPA 13 fire sprinkler system requirements for protecting Ceiling Pockets, Ceiling Clouds and Skylights •Learn how to determine when fire sprinklers are and are not required •Describe the spacing rules of fire sprinklers related to these architectural element 13, 13R, 13D: Calculations and High Ceilings I was reading through NFPA 13 (2016 ed.) and caught Section 8.10.2.2: Residential Sprinklers shall not be permitted to be used on ceilings with slopes greater than 8 or 12 or ceiling heights greater than 24 feet unless specifically listed for this purpose In most conditions, NFPA 13 requires sprinklers at both the structural ceiling and cloud ceiling panel elevations. However, there are some situations where sprinklers can be located on one level or the other.

To omit sprinklers above the cloud ceiling, the functional limitation is a maximum 1 in. gap between clouds per vertical foot of height from the floor to the cloud, up to a maximum of 20 ft COLIN L. And I agree with Jonathan, in order to determine whether or not the obstruction within 18 of the ceiling is going to affect the sprinkler spray pattern, you could either use the 3x rule of 8.6.5.2.1.3, or you might treat the cloud like a soffit and use 8.6.5.1.2 (2016) to ensure that the horizontal distance from the sprinkler to the. The National Fire Protection Association (NFPA) 13, the design guideline used for fire sprinkler design, does not yet contain specific guidelines for sprinkler installation in the clouds.

Section 9.3.11.1 of NFPA 13 allows drop-out ceilings to be installed below sprinklers if the drop-out ceiling materials are listed for that application. The other Sections of 9.3.11 address issues such as limits on use o The ceiling tiles and panels are mounted in a ceiling grid system to provide a finished ceiling appearance, and a sprinkler system, located in the interstitial space above the drop-out panels, is installed in accordance with NFPA 13. The ceiling panels are intended to fall out prior to sprinkler activation such that the ceiling tiles do not. NFPA 13 does detail more information on cover plate installation, but there is no specific code for the distance between the cover plate and the ceiling. It is important that the cover plate isn't too loose or too tight, however, as either condition may cause the plate and sprinkler to fail to activate on time This webinar addresses these challenges such as high ceilings, cloud ceilings, slatted ceilings, integrated HVAC ceiling panels, concealed spaces, etc. The NFPA 13 standard cannot be expected to address all, so there are some methods, approaches, and resources that can be deployed to keep the project on track These cloud ceilings present unique challenges to fire sprinkler installation. The solution to these challenges are not always easily found clearly in the pages of NFPA 13. However, by applying.

Cloud ceilings are a type of suspended ceiling system consisting of decorative panels separated by gaps. The panels come in a variety of shapes, sizes, and styles and give ceilings a more architectural look, compared to a traditional flat acoustical ceiling tile system This class will provide an overview for the research that was done throughout the first two phases of this project.

I note NFPA 13:2016 clause 8.15.24 gives some guidance and it seems to indicate our ceiling arrangement would not require sprinklers above the clouds or have any specific sprinkler location requirements This article explores a third approach—drop-out ceilings. NFPA 13, Paragraph 3.3.9, defines a drop-out ceiling as: A suspended ceiling system, which is installed below the sprinklers, with listed translucent or opaque panels that are heat-sensitive and fall from their setting when exposed to heat. Drop-out ceiling systems have been in use.
