Includes a new educational chapter for designers and specifiers, to aid in the specification and implementation of duct leakage and testing methods. Understanding the Basics is a comprehensive non-technical manual written to provide an overview of HVAC systems and can be used for self-study, group training, or reference.

Covers fire dampers, breakaway connections, combination fire and smoke dampers, framing of structural openings, contract plan marking, installation instructions and special applications.

Architectural sections include elaborate cornices, skylights, domes, spires, spun balusters, gargoyles, smacma, storefronts, metal buildings and metal roofs. This booklet of waterproofing illustrations and reminders covers curb and roof penetrations and sealings, as well as the interface between the roof and the location at which the manuaal, piping, electrical wiring or sheet metal ductwork pass through the roof. It is a new American National Standard.

Also covers flashing, metal roofs, copings, gravel-stop fascia. Need a leg up on the competition?

Presents practical troubleshooting and corrective tips for typical problems of roof panels, gutters, downspouts, fascia, copings, flashing, ridges and hips, valleys, expansion joints, penetrations, fasteners and soldering. Included are new tables for stainless steels and aluminum, plus expanded chapters on materials, welding practices, and a guide specification. The duct sizing tool offers a inch maximum duct diameter. As alternatives to table use, the publication has a manual calculation procedure using equations and fully developed examples, and offers optional calculation software.

Achieving uniqueness in building construction should start at the top. The safety chapter covers such items as health effects, hazard controls and safety procedures. Covers the fundamentals of space condition requirements and explains how the various types of air, hydronic and refrigeration HVAC manuql designs can be applied to buildings.

It reviews materials and reinforcement of duct systems, as well as assembly and supports of ducts. Also covers details for connections to equipment and air terminals, hanger schedules, reinforcement requirements, fabrication of rectangular duct and fittings, closures of seams and joints, channel and tie rod reinforcements, plus hangers and supports. It gives guidance in understanding these synthetic materials, as well as assistance in determining their strengths, corrosion resistance and advantages over other materials.


Architects and designers are encouraged to use this invaluable resource to assure that their specifications reflect professionally vetted design details.

The manual incorporates the current technology available for contractors and designers to provide a state-of-the-art system.

It also includes sample reports and timesaving pre-start and start-up checklists. Contractors interested in new opportunities will find market entry guidance and ideas to assist them in the development of new business strategies that target the renovation of existing buildings.

Download all of this and more amnual from members-only section of www. The request must pertain to a specifically identified portion of a SMACNA technical document that does not involve published text which already provides the requested information.

A written safety and health program is essential to many project bid documents. In addition, variable frequency drives, direct digital control systems, lab smaacna exhaust balancing and the latest balancing equipment and procedures are presented. Methods to identify and remediate lead, asbestos, or other materials that are classified as hazardous materials are not intended to be within the scope of this standard.

The Guideline covers how to manage the source of air pollutants, control measures, quality control and documentation, communication with occupants. It applies to the commercial, industrial and institutional markets. Sheet Metal Welding Guide This publication and the wealth of information it contains are intended to assist contractors, estimators and shop supervisors in profitably managing the welding activity in a sheet metal shop.

Session highlights the considerations in specifying and installing fire dampers, smoke dampers, combination fire and smoke sacna and ceiling dampers in HVAC systems. Technical Inquiry SMACNA develops and publishes more than 30 technical documents with more being added to the library each year and several in review and revision cycles. Here are some examples.

Updated coverage of welding processes; flux-cored wire guidelines; and the latest equipment. Available to both members and non-members. Accepted Industry Practice For Industrial Duct Construction This guide is a compilation of accepted industry practices and construction techniques having received wide acceptance for the fabrication and installation of industrial duct systems.

These recorded webinars cover business management, safety and health, labor relations and technical topics are available at no cost to SMACNA members.

Sign Up For E-News. Basic formulas used in the industry for recovering shop burden costs make this guide a real gem.


Emphasizes the importance of regular and appropriately timed inspections because a small problem discovered early can manula 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.

Items of special interest include performance contracting, CFC refrigeration regulation, and new automation system open protocols. It is an updated product that provides a source of the labor units data required to fabricate and install HVAC materials and equipment. New in this edition is an engineering and design chapter to provide additional information to design professionals, double-wall construction details, new casing construction details and additional accessory items.

These drawings illustrate the best practices in custom architectural sheet metal work. Includes tables for selection of free standing stacks from 20 feet to feet high, and diameters to inches, companion flange, stiffener sizes and stacks with access ladders and platforms.

Individual chapters detail system information for controls, multizone, dual duct, terminal reheat, variable air volume, induction and special applications such as dedicated outside air and thermal energy storage. A model specification enables one to easily prepare custom project smmacna for installation of PVC air handling systems.

Technical Resources

It presents accepted industrial practices for the application of sheet metal lagging to manuak duct, pipe, tanks, boilers, furnaces and other accessories. New to the publication are design considerations for free standing stacks under resonant vibration, established limits on stacks fitted with testing platforms, larger stack selection diameters, and consideration of custom designed anchoring systems instead of a standardized schedule.

Make a Technical Inquiry. The new edition includes a smavna extensive list of fee options and has been revised to comply with current building codes all within a single document for user convenience. Construction Standards Accepted Industry Practices for Sheet Metal Lagging Providing numerous examples of sheet metal lagging applications, this publication assists the designer, contractor and plant engineer in understanding and solving the complexities involved in the design, fabrication and installation of sheet metal lagging systems.
