Fire Sprinklers Installed For Sloped Roof

In the face of an advancing wildfire a structure with a properly implemented firesmart program in combination with an operational exterior rooftop sprinkler system has a survival probability of above 90.

Fire sprinklers installed for sloped roof.

Must be offset at least one channel laterally from any ridgeline sprinkler. For the 33 degree roof inclination equivalent to an 8 in 12 roof slope the water flux on top of the fire source is reduced by 50. The sloped ceiling may also alter sprinkler spray patterns depending on sprinkler installation details e g. Sprinklers must be installed with the frame arms perpendicular to the roof slope.

Sprinklers are one of the oldest methods but one of the newest technologies in wildfire control and property fire protection in wildland areas. Roofs having a pitch not exceeding 2. Roof top sprinkler systems fact. 12 16 7 are considered horizontal and sprinklers shall be permitted to be installed with deflectors horizontal.

When compared to standard spray sprinklers which have restricted nfpa 13 installation criteria within attic spaces. Centerline of sprinkler must be a minimum of 6 laterally from face of truss see figure 8. Sidewall sprinklers are required to have the deflector aligned parallel to ceiling or roof slopes nfpa 13 2002 2016 editions section 8 7 4 2 and where the slope exceeds 2 in 12 the sprinkler must be located at the high point of the slope and be positioned downward nfpa 13 2002 2016 editions section 8 7 4 2 2. Rooftop sprinklers are a proven method of improving the chances that a building will survive a wild fire according to various studies.

Deflector parallel to the sloped roof above. Deploy on the roof of a structure and around the perimeter of a structure for complete fire protection coverage. These sprinklers are specifically intended for use in combustible and non combustible sloped attic spaces and have been developed to produce unique water spray patterns to enhance sprinkler placement while improving fire control. Deflector orientation and or standoff distance.

Additionally as with all. Our roof sprinkler systems have been designed specifically for structural perimeter protection from urban interface wildland fires features include. These modified transport dynamics may increase the suppression challenge through increased fire size. When rooftop sprinklers are activated they spray water high up in the air which lands on the roof trees and other surfaces that are within range.
