Pilkington Pyrodur™ Plus is an advanced
thin, clear fire-resistant laminate glass,
which easily meets all the latest European
fire and impact standards. Using a special
clear intumescent interlayer; it offers
an excellent combination of fire and impact
performance, making it the ideal choice
for internal fire-resistant doors and
partitions.
Narrow profile nominally
7.5mm thick.
Integrity fire performance,
30 minutes classfication.
Partial insulation
and exceptionally low Ievels of transmitted
radiant heat.
Impact performance
to BS6206: 1981 Class C.
Meets thc requirements
of the new European impact standard as
a laminated glass.
Fire
Performance
Fire Glass:
In the event of fire, the interlayer intumesces
and turns from clear to opaque, so creating
an effective integrity barrier against
hot gases and flames.
Once
opaque, the interlayer also significantly
cuts down the Ievel of radiant heat from
the fire, achieving exceptionally low
radiant heat intensities for such a thin
integrity glass.
Under
independent testing conditions, (reference
test reports RF00137 and RF00138), integrity
in excess of 40 minutes was achieved -
a safety margin of 30%, above the minimum
clas)fication time of 30 minutes.
Performance
in the tests allows an approved fire door
containing Pilkington Pyrodur™ Plus
to bc classfied as a Category B door within
the specific provisions of BS EN 1634-1,
which allows specific increases in dimensions
under the field of direct application
allowed by the standard.
Impact
safety
Pilkington Pyrodur™ Plus complies
with BS6206: 1981 Class C and, when tested
according to the new European standard,
it shows safe breakage in the manner of
a Iaminated glass.
Sound
insulation
Pilkington Pyrodur™ Plus offers
an acoustic improvement over standard
fire-resistant glass of similar thickness.
The Rw index (weighted sound reduction)
is 35dB
Applications
and usage
Pilkington
Pyrodur™ Plus provides the optimum
combination of fire and impact performance,
making it the ideal choice for fire-resistant
doors and partitions. It can only be used
in internal applications.
Finished
sizes of Pilkington Pyrodur™ Plus
are supplied with a distinctive silver
edge tape. This tape must not be removed
or replaced, nor must thc glass be proccssed
or cut to any other size than that supplied.
Application
applies to the normal environmcntal conditions
found in occupied places of work or assembly.
Glazing
As with any other fire-resistant
glass, Pilkington Pyrodur™ Plus
must only be used as part of an appropriately
rated system. We recommend that glazing
is carried out by a FTRAS accredited installer.
Whilst
Pilkington Pyrodur™ Plus can be
easily glazed, due to the nature of the
special interlayer handling guidelines
must be adhered to. Copies of these guidelines
are available on request.
Glass
weight is typically 18kg per m2 and thickness
tolerances fall within the limits set
by BS EN 12543-5 (ie. +/- lmm).
