PYROBEL ~ Fire
Resistant Glass
(Approved by BOMBA Malaysia) |
|
OVERVIEW
Architects and designers are increasingly looking for larger
blazed screens and doors to provide buildings with new aesthetic
designs and more comfort and safety for the people who use them.
But in many cases, these glazings must be fire resistant to
comply with the building regulations which aim to stop the
spread of fire and to enable a safe evacuation of the building.
To fulfil these requirements, the manufacturer has developed the
pyrobel range of fire resistant glasses, tested and approved
according BS 476:Part22:1987, on both Integrity and Insulation
criteria. Pyrobel is a fully transparent fire resistant glass,
available in large sizes, which offers valuable sound reduction
properties and complies with safety requirements of BS 6206. |
 |
 |
|
|
|
|
PYROBEL
Pyrobel is a multi-laminated glass assembled with clear
intumescent interlayers.
In case of fire, these interlayers expand at around
120°C and transform into a rigid and opaque shield.
|
|
Once formed, this opaque shield
enables the glazing to meet: |
|
|
the integrity criterion, as the
glazing will not collapse, nor let any flames, smoke or
hot gases pass through. |
|
|
The insulation criterion, as no
radiant nor conductive heat are transmitted. |
| |
|
|
Pyrobel provides a complete
protection against fire: |
|
|
the integrity function ensures
that the fire will not spread to adjacent rooms, stairs,
floors or buildings; |
|
|
the insulation function avoids the
danger or combustible materials being ignited on the
protected side and ensures a safe and panic-free
evacuation as people will not see any flames nor feel
any heat. |
|
|
 |
|
| |
|
APPLICATIONS
Pyrobel can be used in all applications where building
regulations stipulate a specific level of fire resistance and
where natural light and clear visibility are required, such as:
hospitals
schools
hotels, restaurants
stores, shopping centres
office buildings, computers rooms
industrial buildings, warehouses, laboratories
airports
|
|

FIRE REGULATIONS
Fire regulations are specified by several national and
international standards.
Building regulations, By-laws and Codes describe the specify
level of fire protection required (criteria, period of time).
Pyrobel glass is only a part of a complete fire resistant
system. It is the responsibility of the users to ensure that the
fire resistant element as a whole satisfies the current
regulations, and to obtain the approval from the competent
authorities.
The manufacturer disclaim all liability should Pyrobel be installed in
systems that do not company with the regulations.
Pyrobel has been successfully tested according to most European
standards, including BS 476:Part 22: 1987 (which, together with
BS 476: Parts 20, 21, 23 and 24 supersedes BS 476: Part 8:
1972). |

FIRE TEST
The element to be fire tested is placed in front of a
furnace that is heated according the Time/Temperature Curve
described by the respective standards.
Two different criteria are considered:
INTEGRITY
i.e. the ability of the element to prevent the passage of flames
or hot gases. This criterion is assessed either visually (no
collapsing or sustained flaming), by means of a cotton fibre pad
(no glowing of flaming) or by gauges that may not penetrate
through cracks or tears in the glazing. |
|
 |
|
|
|
INSULATION
i.e. the ability of the element to stop conductive and radiant
heat. The mean temperature on the unexposed face must not
increase by more than 140°C above ambient, nor must it increase
by more than 180°C above ambient at one point. A fire resistant
glass must fulfil at least the integrity criterion. Pyrobel
glasses fulfil both integrity and insulation criteria for
durations of 30, 60, 90 or 120 minutes. Please refer to the
respective Pyrobel data sheets for more details. |
|
| |
|
QUALITY
The Pyrobel quality and performances are carefully
controlled at each step of production. Due to the nature of its
special intumescent interlayers, Pyrobel may exhibit or develop
some minor imperfections such as small inclusions and bubbles, a
slight distortion and a light haze. These features which do not
affect the free vision nor the fire resistance of the glazing
shall not be considered as defects provided the variation of
haze and light transmission do not exceed 5%. The edge area may
include larger air bubbles or imperfections that will be hidden
by the rebates.
|
|
 |
|
|
STORAGE
Pyrobel must be stored in dry and ventilated conditions, at temperatures
between -20°C and 40°C, not exposed to solar radiation or UV light. In
case, Pyrobel must always be transported and stored in upright position.
On racks, Pyrobel must be stored slightly inclined (6 to 10° from the
vertical) and fully supported. A soft spacer must be placed between each
glazing. Do not pile up more than 20 sheets per rack. Pyrobel is
delivered in ready-to-install cut sizes, with and edge protection tape.
Pyrobel can not be cut on site and the edge protection tape must not be
removed nor damaged. |
| |
GLAZING INSTRUCTIONS
|
|
|
Do not allow any contact of the
glazings edges with water. |
|
|
Do not install Pyrobel in
locations where the glass temperature might exceed 40°C. |
|
|
Always refer to the fire test
reports. |
|
|
Avoid all glass to metal contact. |
|
|
Do not exercice any restraint on
the glazing. |
|
|
Do not damage the glazings edges
not the protection tape. |
|
|
Keep the rebates dry and free from
aggressive products (acids, organic solvents, ets.). |
|
|
Use hardwood setting blocs or
equivalent (shore hardness A 75) |
|
|
Provide an edge clearance of 4-5
mm. |
|
|
Provide front and black clearances
of 4-5 mm, using closed cells foam tape. |
|
|
Provide a rebate depth of minimum
20 mm. |
|
|
Apply a neutral silicone sealant
immediately after glazing. |
|
|
 |
|
| |
|
EXTERNAL GLAZING
For external application, or in case of direct solar radiation
on the glazing, Pyrobel is available as external grade, with a
UV filter.
Pyrobel external grade must be correctly orientated, according
to its label.
The glazing must be either fully bedded using neutral silicone
or installed in drained and ventilated rebates and carefully
sealed with a neutral silicone capping.
Outside applications are only permitted if the temperature limit
of 470°C is not likely to be exceeded.
For future advice on glazing details, please refer to the
respective Pyrobel data sheets or to Glaverbel technical
services. |

PYROBELITE
For applications where fire resistant glasses with a rating of 30
minutes integrity only are required, Glaverbel has developed Pyrobelite,
a new product thinner than Pyrobel but based on the same technology,
that offers comparable advantages of clearness, safety, sound reduction
and availability in small to large sizes from stock.
Pyrobelite is a laminated glass assembled with only one clear
intumescent interlayer. Pyrobelite meets the integrity criterion of BS
476:Part 22:1987 for a duration of 30 minutes.
Contrary to the other monolithic fire resistant integrity glasses that
remain clear when exposed to fire, Pyrobelite turns opaque as its
interlayer expands. This characteristic reduces the heat transfer
through the glazing and ensures a safe and panic-free evacuation of the
building.
Last but not least, the protection offered by Pyrobelite after formal
integrity failure is still very effective, as the Pyrobelite is
available as 7 mm glazing for interior use and 11 mm glazing for outside
use or high safety applications (class A according to BS 6206).
Please refer to the Pyrobel data sheet for more details. |

PYROCET FIRE
RESISTANT GLASS
FIRE RATING: 60 MINUTES INTEGRITY
DESCRIPTION
PYROFIRE (M) SDN BHD has teamed up with C3S
Securiglass of United Kingdom to offer users a Fire-rated One Hour
Glazing System popularly used in Europe. This system uses a 6mm thick
glass panel, Pyrocet, - a super tough monolithic fire resistance glass
panel housed in a stainless steel frame profiled to exacting standards
to ensure performance.
State-of-the-art technology today has made it possible to make glass
that combines high strength with high fire resistance properties. This
monolithic glass has a strength that is at least 6 times stronger than
conventional float glass of the same thickness and 1.5 times stronger
than tempered glass. Its usage therefore allows for greater safety to
life and property in buildings.
PYROFIRE Glazing System is best used in high traffic areas and offices.
It is an ideal passive fire-fighting material and its see-through effect
makes it a choice material for Internal Partition Walls, Control Rooms,
Clean Rooms, Glass Curtains, Windows, Facades, High Traffic Entrances,
Escape Doors or Emergency Doors, Fire/Smoke Barriers, Safety Barriers
etc.
PYROFIRE Glazing System is already in use in Malaysia for its fire
resistance performance. |
