LONDON GRENFELL TOWER (JUNE 2017)

the use of the flammable cladding being blamed for

spreading the fire that killed at least 70+ people.

Barry Turner, director of technical policy at Local Authority

Building Control, which represents council building control

teams in England and Wales, said: What we need to

know is what was inspected. You can go on site 16

times but not necessarily see everything you need to see.

They may have inspected the fixings, the fire barrier and

the cavity, which are equally important but are useless if

you put a flammable material on the front.

COMBUSTIBILITY V.S. FIRE RESISTANCE

Non-combustibility:

Material characteristic

Test standard: BS 476 Part 4 Non-combustibility test

for materials

Limited combustibility : BS 476 Part 7 Method of test

to determine the classification of the surface spread of

flame of products

Fire resistance:

System Characteristic : openings + penetrant +

firestop sealing

Test standard: Linear joint: BS EN 1366-3 or

Penetration seal: BS EN 1366-4; BS 476 Part 20.

Materials of non-combustible DO NOT mean

they are fire resistance within a given
