An air curtain, also known as an air door, employs a controlled stream of air aimed across an opening to create an air seal. This seal separates different environments while allowing a smooth, unhindered flow of traffic and unobstructed vision through the opening. This course discusses how air curtains work and why they can contribute to occupant comfort, energy efficiency, and indoor air quality when the door is open. It also reviews how air curtains improve whole-building energy efficiency versus conventional methods.

Textile air dispersion systems have come a long way from the days of cotton diffusers and duct socks. Today's systems are custom engineered and constructed from advanced polyester fabrics that offer features and capabilities not possible with other air distribution systems. This course examines the similarities and differences between metal and fabric systems and highlights the design, performance, efficiency, and sustainability characteristics unique to textile air dispersion. As well, the wide-ranging application possibilities for textile systems are explored.
