Mr. Golinveaux says that the new simplified field installation for sloped-ceiling spaces is the result of eight years of study, testing, and cooperation. He tells us that this research was done to provide data on the “life safety” potential of residential sprinklers on sloped ceilings outside of the “listing”
A Fire Protection Research Foundation study  found that “residential sprinklers listed for applications with flat, smooth ceilings can be expected to perform adequately when installed on a sloped ceiling or sloped and beamed ceiling arrangements similar to those investigated as part of this study”; with certain restrictions and limitations related to design configurations.
According to Mr. Golinveaux “practically speaking” the 2013 edition of NFPA 13D results in the following benefits:
- Sprinkler contractors will realize a reduction of labor costs from quicker installations;
- Municipal authorities will be confident knowing that a prescriptive standard is being followed;
- Homebuilders can be confident that the cost for a home’s fire protection system will come in on, or close to, budget; and
- Homeowners will have an economical, effective and life-saving fire protection system in place that did not substantially increase the price of their home.
