QF1 Fire Protection Compound

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 cables 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: 2424).

• 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 containing two series of penetrations. Heavy-duty and lightweight electricity cables, held in galvanized mild steel cable trays, and were pointed up in QF1 Fire Protection Compound to a thickness of 160 mm. Results demonstrated that the integrity and insulation values of QF1 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.

• Formulated to retain some flexibility on curing and intended for use to seal gaps around electrical cables where this physical characteristic allows subsequent installation of additional cables without the need to use masonry drilling equipment. A screwdriver or similar tool can be used to form a hole through the seal; the new cable can then be threaded through and any residual gap filled with a further application of QF1 compound.

Coverage:

One square metre at 160 mm thickness requires approximately 160 kg (8 x 20 kg sacks) of QF1 and will provide a four hour rated fire seal.
