Once the temperature in the room which is ablaze reaches
a certain level, the intumescent material expands as a
foam crushing the pipe and closing off the cross section,
therefore preventing (for a specified length of time) the
fire and smoke from spreading through the opening.
Geberit HDPE and Geberit Silent-db20 fire protection
sleeves are Class 90, giving 90 minutes of fire protection.

Fire protection
To comply with building regulations B3 where pipes pass
through fire rated barriers, Geberit provides intumescent
fire sleeves that also incorporate a separate acoustic
sleeving. Geberit Fire Protection Sleeve RS90 Plus EN is
tested to BS EN 1366-3:2009 – Fire resistance tests for
service installations. Penetration seals.
Intumescent collars can be fitted using any means of
installation shown in Fig A or Fig B. Any gaps between
construction and pipe penetration are to be filled with a
fire rated intumescent mastic.
• Fire protection walls/ceilings require pipe penetrations
to be fire sleeved.
