Description

The ASTROflame range of Astro DS duct sleeves are intended for use where a ventilation duct passes through a fire CE Certification for Astro Duct Sleeverated wall. The sleeve maintains the integrity of the fire rated wall which would otherwise be lost.

In the event of a fire, the advanced Astro DS Duct Sleeve will expand with the heat, crushing the duct and closing off the hole to the fire for at least 2 hours except the 220x90mm version which is rated 60mins.

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.
