Fire Stopping Selector
List the service penetrations through fire rated walls and floors and get the generic type of fire stopping each one needs: by service, pipe material and size, wall or floor type and fire rating. Flags the cases that need special care, builds a penetration schedule for inspection and shows the standard fire curve the seal has to survive.
How to use: add each penetration type with its wall or floor, rating, service and size. The seal type is generic: always use a tested system from one maker that matches the exact case. Tap i for help.

5. How it works
What fire stopping does
A fire rated wall or floor only works if every hole through it is sealed to the same rating. Fire stopping restores integrity (no flames or hot gases through) and insulation (the unexposed side stays below about 140 K average and 180 K maximum rise) around pipes, cables, ducts and trays.
Matching seal to service
Metal pipes do not melt but conduct heat, so they need a sealant or mineral wool seal and sometimes lagging to meet insulation. Plastic pipes melt and leave a hole, so they need intumescent collars or wraps that swell and close it. Cables and trays use coated batts, sealants or cable transits. Ducts pass through with a fire damper or as fire rated ductwork. Combustible pipe insulation must be part of the tested system.
Tested systems only
Every seal must match a tested and listed system: the same wall or floor, service, material, size, insulation, pipe end configuration (U/U, C/U for plastics in EN 1366-3) and annular gap. Mixing products from different makers is not allowed. Label each seal, keep the system data sheet in the O&M manual and have it inspected before ceilings close.
Selector gives the generic seal family only. The system, product and installation detail come from the fire stopping maker's tested data and the project fire engineer, and must meet the UAE Fire and Life Safety Code, NZBC C/AS2 or NCC as applicable.
