Insulated air ducts
Insulated air ducts are mainly used for transition segments where air of a certain temperature must be supplied into the emission area, keeping in account the loss of heat energy along the air duct’s entire length. Such a system provides a means to minimize changes in temperature along the air duct. A synthetic nonflammable material is used for insulation, which is located between the external and internal fabric layer. Also, air ducts such of these do a wonderful job of insulating sound.
