Insulation- Insulation must be placed in a manner that provides the piping ❑ ❑ ❑ <br /> warmth from the heated space and insulation from the cold space.Tenting of the <br /> insulation ensures that the piping has an open-air space to the heated <br /> environment.The tenting must be stapled in place to ensure that the heat from <br /> below reaches the piping and prevents freezing of the water in the pipe. (See <br /> insulation arrangement detail) <br /> INSULATION ARRANGEMENT DETAIL <br /> W. <br /> Caution: It is important that the <br /> insulation be installed tight against the <br /> joists. In unheated areas, any spaces <br /> or voids between the insulation and the <br /> joists cause the water in the fire sprinkler <br /> piping to freeze. <br /> Fire Marshal's Office 425.257.8100 I everettwa.gov/fire I INFORMATION HANDOUT C-7 4.20.2020 I Page 4 <br />
