About the DS Duct Sleeve Product
The range of DS Duct Sleeves are intended for use where a ventilation duct passes through a fire rated wall. The sleeve maintains the integrity of the fire rated wall which would otherwise be lost.
In the event of a fire, the advanced DS Duct Sleeve will expand with the heat, crushing the duct and closing off the hole to the fire for up to 120 minutes.
The Ventilation duct sleeves are available to fit all common sizes of plastic ventilation duct and are suitable for retro fitting with access only required from one side.
