Fire Protection Contractor Magazine, the most widely read sprinkler industry publication, has featured Globe's guest article on the evolution of attic protection from the 1980s and how designers can now achieve better fire protection for attics. Globe's attic system reduces hydraulic demand by up to 70%, and the FPC article clarifies how the scheme works and what's different from legacy approaches.
"These newer schemes provide better fire protection in attics by identifying and understanding heat flow paths, maximum points of heat collection, and developing sprinkler devices with more of a directional spray pattern to address the fire origin. With that said, there is required change in behavior that all designers will need to get used to," wrote Globe Vice President of New Technology Kevin Maughan.
"Possibly the biggest behavioral change that needs to occur is that these newer schemes require an understanding of the structural layout of the roof at the earliest possible point of design. The structural layout of trusses has everything to do with how hot gasses will travel as well as the effectiveness of these more “directional” type sprinklers," he continued. "These Special Application sprinklers all have limitations as to where they can be used in relation to the structural framing. While this is an additional consideration that designers will need to utilize, it is also one of the main reasons that these special application schemes are so successful in controlling fires in attics."

The Globe Specific Application Attic Protection Scheme has undergone full-scale fire testing with Underwriters Laboratories and is Listed to be utilized per NFPA 13 in conformance with the New Technology and Equivalency Sections as well as the Special Sprinkler Section.
The Globe Specific Application Attic Protection Scheme has been engineered to consider all construction conditions typically found in the attic built environment. The scheme utilizes a unique strategy with two distinct types of special sprinklers. The positioning and use of these sprinklers in conjunction with each other and their complimentary effects on fire control has been carefully considered for these specific Attic structure hazards. Consequently, the required number of sprinklers to calculate and system demand is drastically reduced from that seen with standard protection schemes or even the more recent Special Application schemes.

About Globe Fire Sprinkler
Globe Fire Sprinkler is a family owned fire sprinkler manufacturer, headquartered in Michigan. We celebrated 100 years of continuous production of Globe Sprinklers and Valves in 2014; the Globe name has persisted in its enduring identity since the introduction of the first Globe Issue "A" Sprinkler in 1914. Globe developed the earliest lever-fulcrum dry pipe valve, Globe Save All center strut sprinklers, and eventually became the first US company to utilize 5mm and 3mm Glass Bulbs in its commercial and residential sprinklers. Its modern era began in 1988 with the guidance and dedication of Golden Sprinkler Award recipient Robert Worthington, P.E. until his passing in 2016. The Worthington family continues to own and operate Globe, under the leadership of Steven Worthington and a team of some of the industry's most seasoned professionals. Globe's heritage as a leading sprinkler manufacturer is reflected in the introductions of the RCW, UM, UMC valves, and other new products the company develops to meet the demands of the world market. The company proudly maintains strong relationships with approval authorities including Underwriters Laboratories Inc, FM Approvals and the Loss Prevention Certification Board (UK). Globe has the LPCB (UK) certification for ISO 9001:2015 series Quality Assurance, therefore exhibiting proof of the quality it continuously builds into each of its 100% factory-tested products.
