Book Overview

HVAC Duct Construction Standards – Metal and Flexible, 4th Edition SMACNA is primarily for commercial and institutional projects and contains first time ratings for the TDF and the TDC connectors. Schedules have been standardized on “minimum” thickness rather than “nominal” thickness of sheet metal – a major change. The new construction standards contain re-rated rectangular, round, oval and flexible duct constructions for positive or negative pressures up to 10″ water gauge (2500 Pa). Widths go to 120″ in gages 26 to 16. Diameters go to 84″ in gauges 28 to 16. New performance requirements facilitate equivalent ratings for non-illustrated construction. The data have been reorganized for easy use and reference; includes soft metrics.

Key Aspects:

  • Flat oval tables for positive/negative pressure applications
  • Spray and aerosolized duct sealants
  • Non-fiberglass duct liner applications
  • Added information on spiral duct fittings
  • Updates to duct hanger requirements
  • Flexible duct hanger spacing and support bracing

Highlights:

  • Updated Duct Construction Standards
  • Detailed Construction Guidelines
  • Installation Requirements
  • Tools for Designers and Contractors
