Fire Protection
Pyro Clear
-
Pilkington Pyroclear® is an advanced toughened fire-resistant glass for use as a basic integrity-only barrier. It is based on a new technology development which we’ve been perfecting and crafting for several years, built on an in-depth understanding of the behaviour of glass in fire, including new knowledge of the detail that influences the probability of glass failure.
Pilkington Pyroclear® is manufactured to high quality control standards, combining the best available expertise in both automotive and architectural premium glass processing. It is based on NSG proprietary technology combined with new R&D insights on the factors that affect the probability of premature failure of advanced toughened glass in fire (long acknowledged as a weakness of this type) and our proprietary accumulated technical experience on glass and glazing systems for integrity fire resistance from years of extensive fire testing and experience in fire safety.
Recent developments include:
Pilkington Pyroclear® Line - enabling Pilkington Pyroclear® to be specified as a butt jointed system, ideally suited for internal glass partitions for 30 and 60 minutes.
Pilkington Pyroclear® Plus - is either combined into an insulating glass unit or into a monolithic laminated glass that achieves an EW60 performance for internal, external screens, external facades and inclined applications - which means that there will be a reduced heat radiation for 60 minutes and in some configurations a 15 minute insulation value can be achieved.
Below is a guide to help you choose the right fire-resistant glass from our range for your application. Also shown below are our fire test summaries with details of some of the many tests carried out on Pilkington Pyroclear® to date.

Pilkington Pyroclear® is an integrity only product for 30 and 60 minutes, (E30 and E60) to BS EN 13501-02
Integrity with reduced heat radiation (EW60) is achieved by using Pilkington Pyroclear® Plus in an insulating glass unit (IGU) or a monolithic laminated glass
Unique product design and system description, manufacturing process and quality assurance system
Recognised to have a superior visual quality due to special processing, high quality toughening and high quality process control
Has achieved a target of more than 50 consecutive successful fire tests in timber framed systems
Designed for compatible edge cover of up to 20 mm for metal frames and 15 mm for timber (NB. Typical value for modified toughened is commonly given as 10 mm maximum to minimise the risks of unpredictable failure)
Exploits our developed proprietary R&D knowledge and expertise on glazing systems in timber frames (system design, materials, glazing arrangements)
Large pane size capability in metal systems (1.970 m x 4.0 m)
Pilkington Pyroclear® has been tested with a variety of glazing seals including a foam tape option for use in timber doors and screens
Produced at our premier architectural glass processing site in the UK to the highest of quality control standards
Pilkington Pyroclear® Line allows large pane butt jointed systems to be specified for 30 and 60 minute internal applications
Pyrodur
-
Using the same technology as Pilkington Pyrostop®, Pilkington Pyrodur® is tried and tested against fire and hot gases.
Pilkington Pyrodur® is widely used and specified in a range of softwood and hardwood timber. Offering up to 60 mins integrity, Pilkington Pyrodur® can combine impact resistance (BS EN 12600) up to Class 1(B)1 and penetration resistance (BS EN 356) to classification P(1)A , which is a requirement in Approved Document Q and recommended in Secured by Design.
In the event of fire, Pilkington Pyrodur® turns opaque providing both the integrity requirements of a barrier to hot gases and flames. As such, Pilkington Pyrodur® complies with British, European and ISO test standards.

Provides passive protection for escape from buildings or firefighter access
Well known and recognised by Fire and Building Control Authorities
Suitable for internal and external applications
Can be used in some of the lightest density and slimmest timber frame profiles
Also suitable for steel, aluminium and fire rated composite frames
Achieves an integrity rating of at least 30 minutes and an insulation rating of 15 minutes
Excellent sound reduction properties
Fire performance not dependent on critical framing edge cover requirements
Pilkington Pyrodur® is available through approved Stockists nationwide who have the technical expertise to help you specify the correct product and advise on installation
Can be incorporated into sealed double glazed units but in order to comply with CE marking requirements these should only be sourced through attestation level 1 suppliers, who are accredited to or licensed for manufacture of Pilkington Pyrodur® fire-resistant sealed units
There is no need for consideration of the fire direction when specifying Pilkington Pyrodur® fire-resistant sealed units
P(1)A classification to BS EN 356
