HVAC PIPING INSULATION 23 07 19 - 1 HVAC Piping Insulation FIBERGLAS Insulation PROJECT ENGINEER RESPONSIBILITY: This is a general specification guide, intended to be used by experienced construction professionals, in conjunction with good construction practice and professional judgment. This guide is to aid in the creation of a complete building specification that is to be fully reviewed and edited by the engineer. Sections of this guide should be included, edited, or omitted based on the requirements of a specific project. It is the responsibility of both the specifier and the purchaser to determine if a product or system is suitable for its intended use. Neither Owens Corning, nor any of its subsidiary or affiliated com- panies, assume any responsibility for the content of this specification guide relative to actual projects and specifically disclaim any and all liability for any errors or omissions in design, detail, structural capability, attachment details, shop drawings or other construc- tion related details, whether based upon the information provided by Owens Corning or otherwise. SECTION 23 07 19 HVAC PIPING INSULATION Note to Specifier: This specification is offered as a guide to specifiers and should be employed at the discretion of the user. The ultimate design and installation are the responsibility of the Engineer or Architect. PART 1 - GENERAL 1.1 SUMMARY A. Section Includes: Provide the following: Note to Specifier: The following temperature ranges are typical for these systems. However, if project requirements call for service temperatures outside the above ranges, consult the manufacturer's published data to determine operating temperature limitations of the insulation product or products under consideration. 1. Cold Piping Systems (chilled water, brine, refrigerant), 32F (0C) to 65F (18C). 2. Dual Temperature Systems, 32F (0C) to 220F (104C). 3. Heating Systems (steam, steam condensate, hot water), ambient up to 450F (232C). 4. Domestic and Service Hot Water Systems, ambient up to 180F (82C). B. Items Not Insulated: Unless otherwise indicated, do not install insulation on the following: 1. Drainage piping located in crawl spaces. 2. Underground piping. 3. Chrome-plated pipes and fittings unless there is a potential for personnel injury. 1.2 REFERENCES A. Thermal insulation materials shall meet the property requirements of one or more of the following specifications as applicable to the specific product or end use: 1.
