> Product Description
The Astro Low Profile Duct Sleeve are a family of CE Marked fire penetration seals designed to firestop PVC ventilation ducts/pipes when installed through fire rated constructions.
The unique vacuum formed intumescent material design ensures that the expansion direction of the material crushes and seals the ducting in a fire situation without the need for any additional metal sleeving.
The lack of metal sleeving, not only makes installation easy, it also limits the risk of heat transfer through the structure as well as allowing compression to ensure a tight seal against fire and smoke or tight fitting against the ceiling soffit where needed.
The Astro Low Profile Duct Sleeve provide fire resistance ratings for Integrity (E) and Insulation (I) for up to EI120 minutes depending on the construction.
Fire Tested for both internal and external wall constructions. The Fire Sleeves are CE Marked with a European Technical Assessment.
The duct sleeves are available to fit common sizes of rectangular and circular plastic ventilation ducts.
