Description

London Underground approved, pre-mixed inorganic powder suitable for adding to water to produce a mortar which is intended for use as a gap filling material where non-combustible pipes and ducts penetrate fire compartment floors and walls.

Non-combustible compound manufactured from lightweight aggregates, inorganic binders and gypsum cement.

Features and benefits:

  • Approved for use on the London Underground (product ID: 2425).
  • The use of extensive shuttering is not necessary.
  • Non-flammable/ non-explosive.
  • Manufactured in the UK.
  • Expected to last the lifetime of the service installation.

Standards and approvals:

Tested in accordance with BS 476: Part 20: 1987. The tests were conducted on a fire compartment wall penetrated by a variety of services which included galvanized sheet metal duct and iron pipes, all pointed up in QF4 compound to a thickness of 160 mm. Results demonstrated that the integrity and insulation values of QF4 were retained for four hours.

Application/ installation:

  • Suitable for use in all types of building.
  • Compatible with most building materials.
  • After mixing with clean water, can be poured or trowelled into position
  • Easily workable, and can be built up on flat surfaces without slumping.

Coverage:

One square metre at 160 mm thickness requires approximately 320 kg (13 x 25 kg sacks) of QF4 and will provide a four hour rated fire seal.
