Our range of duct sleeves are intended for use where a ventilation duct passes through a fire rated wall while still allowing the thermal movement of the duct. The sleeve maintains the integrity of the fire rated wall which would otherwise be lost, and also provide excellent acoustic insulation too.

In the event of a fire, the advanced duct sleeve will expand with the heat, crushing the duct and closing off the hole to the fire for at least 2 hours to match the ceiling, except the 220x90mm version which is 60 minute.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.

Our duct sleeves have been independently tested in accordance with BS476 Parts 20 and 22:1987, EN 1366-3 : 2009 and EN 13501-1 : 2007. Supplied in sizes from 110mm x 54mm to 308mm x 29mm, all with a length of 180mm. The sleeves are easily cut to size to minimize wastage, with no mastic required, thereby reducing on site time.

    I called fireprotectiononline for advice before purchase and this was given in full, and promptly. The vent collar was delivered quickly and was easy to use. Excellent all round.
