Perhaps you mean fire ventilation? In most cases, fire ventilation is installed in commercial buildings. This type of ventilation prevents the spread of fire and removes smoke from the room. I have seen such ventilation only a few times in residential buildings built several years ago. If you have something like this at home, you’re in luck. The most important thing is the constant care of such a structure. Problems often arise from dirt and dampness, which can create an undesirable odor.

I-Stud Cavity Shaft Wall Systems can be erected horizontally and used as economical fire resistive assemblies for corridor ceilings, stair soffits and protection for mechanical ducts. Depending on the span of your ceiling, I-Stud and J-Track depth and gauge required will vary. The I-Stud Cavity Shaft Wall Systems for Horizontal Duct Protection consist of I-Studs 24″ o.c. with 1″ Fire-Shield Shaftliner panels inserted in the steel tabs, and three layers of 1/2″ Fire-Shield C wallboard attached to the stud flanges opposite the Shaft liner panels. This system provides fire protection for mechanical ducts and has been tested from both sides. (Refer to WHI-694-0300.1.) Single layer 5/8″ Fire-Shield or Fire-Shield C wallboard attached to the stud flanges opposite the 1″ Shaft liner panels provide one-hour fire protection when used as a corridor ceiling or stair suffix. Two layers of 1/2″ Fire-Shield C wallboard attached to the stud flanges opposite the 1″ Shaft liner provide two-hour fire pr
