HVAC Duct Construction Standards – Metal and Flexible

Commissioning is the process of ensuring the HVAC system meets the wmacna operational requirements. Lift Truck Train the Trainer Training. Contains the latest and most useful information from manufacturers, fabricators, and corrosion specialists on the use and application of thermoplastic materials. Items of special interest include performance contracting, CFC refrigeration regulation, and new automation system open protocols.

The appendices on smoke control and smoke detectors have been revised to reflect the current technology and requirements for those applications. This handbook is a compilation of accepted industry practices for the construction of duct systems designed to convey air and gases that usually contain particulate or corrosive aerosols. This document contains accepted industry practices for the fabrication and installation of sheet metal lagging, used to cover and protect insulated areas of equipment.

Other topics covered are testing and identification and source mitigation. The manual incorporates the current technology available for contractors and designers to provide a state-of-the-art system.

HVAC Duct Construction Standards – Metal and Flexible

This Standadds contains all figures in DXF format that are used to illustrate the best practices in architectural sheet metal work. Can be used for positive and negative pressure tests.

Events Calendar of Events Holiday Schedule.

It applies to the commercial industrial and institutional markets. Provides guidance for HVAC system selection, operation, and design.

A model specification enables one to easily prepare custom project documents for installation of PVC air handling systems. This publication is intended to assist the designer, contractor and plant engineer in understanding and solving the complexities involved in the design, fabrication and installation of sheet metal lagging systems. Building Systems Analysis and Retrofit Manual. The standard is applicable for construction using uncoated steel, galvanized and stainless steels and a limited range of aluminum ducts.


Offers a standardized, engineered basis for design and construction of industrial ducts of Classes 1 to 5. Sources of data on design of guyed stacks are also listed.

Includes a spiral duct chapter for Classes 1 and 2, covers design pressures ranging from 30″ w. Also provides smxcna information regarding construction of these architectural elements, the purpose of each, as well as what to look for during periodic inspections. Updated coverage of welding processes; flux-cored wire guidelines; and the latest equipment.

It reviews materials and reinforcement of duct systems, as well as assembly constructiin supports of ducts. Contractors will find this book a valuable resource to provide owners or facility managers along with the standard building completion documents.

Emphasizes the importance of regular and appropriately timed inspections because a small problem discovered early can be fixed at a low cost, preventing minor damage from becoming a substantial problem until the cost of repair and remediation becomes excessive.

Sections include load calculations, duct design, duct construction, insulation, vents, air terminals, control applications, system specifications and other updated industry equipment and methods for residential systems. Timesaving IAQ tracking forms can be modified to meet specific contractor needs.

Includes tables, shelves and wall lining details as well as minimum dimension and metal thickness standards for constructing light, medium and heavy-duty kitchen equipment that should provide owners with years of trouble-free usage.

Sealants, moisture transfer methods and air leakage are also covered. A basic reference guide to industry-accepted practices for fabrication and installation of commercial kitchen ventilation systems and custom-built food preparation equipment. As alternatives to table use, the publication has a manual calculation procedure using equations and fully developed examples, and offers optional calculation software.

A thorough explanation of recommissioning leads one through the preliminary investigation, survey and documentation phase, the design and installation of system modifications, and the actual recommissioning test.

Identified as DALT by some government agencies. Assists the designer, contractor and code officials in understanding the complexities of designing, installing, construction and balancing both the exhaust and make-up air systems required in commercial kitchen ventilation. The guide assists TAB technicians with preplanning and establishing teams so that energy use is minimized whether the work is done in new or existing buildings.


In addition to the basic engineering guidelines for the sizing of HVAC ductwork systems, the manual also provides related information on materials, methods of construction, economics of duct systems, duct system layout, pressure losses, fan selection, duct leakage, acoustic considerations, and Testing, Adjusting and Balancing TAB. The manual shows how very low- and very high-risk areas of the country can be accommodated. It contains negative pressure construction for 4″ w.

The new edition includes a more extensive list of bracing options and has been revised to comply with current building codes all within a single document for user convenience.

Whoops, our bad…

Dtandards an updated level of technical information necessary for energy conservation and retrofits of today’s commercial facilities.

The food service equipment section offers practical guidelines for designing, fabrication, evaluating and installing a wide range of custom-built food service equipment. Carefully examining the information along with the local climate conditions will enable users to select the proper details for practically any residential architectural sheet metal application.

New in this edition is an engineering and design chapter to provide additional information to design professionals, double-wall construction stzndards, new casing construction details and additional accessory items.

Changes to the manual include expanded tables for stainless steel and aluminum, expanded tables for duct sizes up to 96 inches in diameter, introduction of a new Duct Class 5 for systems handling corrosives, and spiral lockseam pipe.

Architects and designers are encouraged to use this invaluable resource to assure that their specifications reflect the proper design details. It also contains master isometric roof plans keyed to details; new roof drainage design data; revised roofing, flashings and copings; wind pressure test reports; model project specifications; and metrication.
