Float Glass Production
Sand, soda ash, Poured into a bath of Glass settles and is
limestone, salt-cake, molten tin at 1100°C pulled out at 600°C
dolomite are melted and annealed
at 1600°C Controlled atmosphere
Washed,

Glass Characteristics
Glass is fundamentally a very strong material
It can be severely weakened by fine cracks
and abrasions
It behaves like a brittle substance
It is usually found in the following forms
– Annealed (patterned)
– PVB laminated
– Thermally toughened
– Wired

Fire-Resistant Glass
Fire-resistant glass will only perform when it
is part of a suitable fire protection system
(i.e. in a tested fire screen)
Glass
Frame & glazing materials
Qualified glazier
(FIRAS Scheme)
Each element in the fire tested system is
as critical as the next
10
When to specify Fire-Resistant Glazing
In the event of fire...
The building should remain structurally intact
Fire spread over the internal linings of the building is inhibited
The external walls and roofs should resist the spread of
fire over their surfaces and fire spread from one building
to another is restricted
There should be sufficient degree of fire separation within the
building and between adjoining means of escape
There should be adequate means of escape
There should be easy access for fire fighters and rescue teams
11
When to specify Fire-Resistant Glazing
Building Regulations provide guidance on
the safe access and egress of buildings
The Building Control Act 1990
The Building Control Regulations (SI 496 of 1997)
Technical Guidance Document B: Fire Safety
Construction Products Directive (89/106/EEC) &
SI 198 of 1992
Approved Document E (Northern Ireland) 1994
Approved Document B (England & Wales)
12
When to specify Fire-Resistant Glazing
Building Regulations provide guidance on
the safe access and egress of buildings
British Standards Code of Practice for Fire Precautions
in the Design of Buildings, specifically BS 5588, give
alternative guidance on aspects of fire safety design
Some buildings are more complex in design
or incorporate features not covered by Approved
Document, Part B, e.g. Atria
Smoke screens are covered by BS 7346: 1990 Part 3
Specification for Smoke Curtains
13
Fire Tests on Building Materials
& Structures
BS 476: Part 22: 1987
Non load-bearing glazed elements have to be
tested to BS 476: Part 22: 1987: Clause 10
Two classifications
– ‘Integrity’
– ‘Insulation’
Fire performance is rated in 30 minute steps
(i.e. 30, 60, 90 or 120 minutes)
Fire-resistant glass is specified by two numbers,
the first referring to the integrity rating, the
second to the insulation rating
14
Fire Tests on Building Materials
& Structures
IS EN 13501-2 Classification document
– ‘Integrity’
– ‘Radiation’
– ‘Insulation’
Fire performance is rated in given steps
(i.e. 20, 30, 60, 90 or 120 minutes)
Fire-resistant glass is specified by three
numbers, the first referring to the integrity
rating, the second to the insulation rating
15
EN Standards for Fire Tests
European Standards will replace national standards:
IS EN 1363 Part 1 - General requirements for fire-resistance tests
IS EN 1364 Part 1 - Walls including glazing non-load bearing
IS EN 1365 Part 2 - Floors and roofs
IS EN 1634 Part 1 - Fire Doors
IS EN 13501 - 2 - Classification Document*
E - Integrity
EI - Integrity and Insulation
Product standards relating to glass have yet to be published before
fire-resistant glass can be CE marked. There will be a transitional
period from National Standards
*Also : EW – Radiation Classification
16
Definition of ‘Integrity’
According to BS 476: Part 20: 1987
2.9 Integrity
“ The ability of a specimen of a separating element to contain a
fire to specified criteria for collapse, freedom from holes, cracks
and fissures and sustained flaming on the unexposed face.
”
17
Definition of ‘Integrity’ & ‘Insulation’
According to BS 476: Part 20: 1987
2.9 Integrity
“ The ability of a specimen of a separating element to contain a
fire to specified criteria for collapse, freedom from holes, cracks
and fissures and sustained flaming on the unexposed face.
”
and...
2.8 Insulation
“ The ability of a specimen of a separating element to restrict the
temperature rise of the unexposed face to below specified levels.
”
It is very important to distinguish between
‘Integrity’ and ‘Insulation’ in the application
18
Fire Test Evidence
Make sure that…
The fire-resistant glass was tested to
the relevant standard
The fire-resistant glass was tested or
assessed as part of the framing system
The fire testing was carried out by
independent establishments
19
Fire Test Evidence
Manufacturers should be committed to
extensively testing their products and
over the years have carried out
considerable testing with all products
of their fire-resistant glass range
Make sure to always ask
for test evidence!
