Transparent Fire Walls - Rated Protection against heat, flame, smoke and hot gases.
Pilkington Pyrostop® is the product to use wherever a complete, physically robust fire protection shield is desired in combination with the high quality through vision and high quality natural lighting typical of normal glazing.
In the event of fire Pilkington Pyrostop® provides both the integrity requirements of a barrier to smoke, hot gases, and flame, as well as very effective insulation from the heat of a blaze. As such, Pilkington Pyrostop® complies with the very precise temperature criteria defined in European test standards and ISO test standards.
During such a standard test it is possible during the early stages to comfortably touch the surface of Pilkington Pyrostop® on the non-fire side, whilst the inner fire surface of the glass could be exposed to flames with temperatures as high as 1.000 °C. Even by the end of the test, the outer surface glass temperature will be less than an average of 140 °C higher than ambient starting temperature, and in no spot individually higher than 180 °C. These temperatures are a long way away from those that would cause the dangerous spread of fire by radiant heat and spontaneous ignition of flammable furnishings.
So Pilkington Pyrostop® provides not only built in safety for escape or firefighter access, but also protection against the spread of fire and limitation of fire damage. It has an additional benefit that the opaque insulating interlayer blocks out the fire which minimises panic, and acts as a pointer for the fire services, to indicate the presence of fire on the other side.
Pilkington Pyrostop® is suitable for all applications where full fire insulation together with basic protection against flame and smoke is a requirement of the local building regulations. Typical situations are partial or full size fire door and partition glazing along escape routes, room compartmentation, roofs, floors and facade glazing. Pilkington Pyrostop® is also designed to be used in windows to prevent break out of fire and movement of fire along or up the outside face of the building or across re-entrant corners, as well as the prevention of fire transfer from one building to another.
In all installations Pilkington Pyrostop® must always be used as part of a fully approved fire-resistant glazing system. Under no circumstances must it be installed in frames which are not fire rated.
Even thicker Pilkington Pyrostop® versions for longer time fire-resistant ratings of 60 minutes and more are designed to give the high visual quality, high light transmission, and unadulterated colour rendering properties shown by the thinner glazings in the Pilkington Pyrostop® range. This is achieved by the use of Pilkington Optiwhite™ special white glass to optimise transparency.
Whenever architects choose Pilkington Pyrostop® they are ensuring first class fire-resistant protection. They are also working with a glass that allows the realisation of aesthetically pleasing designs in a comfortable and fire safe building environment.
