Pilkington Pyrodur (EW-glazing)

Pilkington Pyrodur® (EW-glazing)
Fire-resistant glass for applications that require protection from fire and smoke in combination with reduced transfer of radiant heat

A range of fire-resistant glass types is available in offering increasing levels of classified protection, which is measured in defined time periods (30, 60, 90, 120 and 180 minutes) and in terms of Integrity and Insulation or Integrity only as designated by the European Standards. It should be noted that fire-resistant glass must always be specified as part of a tested and approved glazing system, and installation should be carried out by specialists in order to ensure that the expected fire performance achieved should be called upon.

Insulation : The ability of a specimen of a separating element to restrict the temperature rise of the unexposed face to below specified levels. 
Temperature rise on the unexposed fire side shall not be more than 140ºC (average value) or 180ºC (maximum individual value) above ambient temperature

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.

Fire Classification
These diverse regulations and requirements for the use of fire-resistant glazing have led to the definition of the European standardised fire-resistance performance classification which comprises three classes:
Class EI : Fire-resistant glass in this category offers highest level of protection from fire, smoke and radiant heat for a defined period of time.
Class EW : Glass in this category offers an integrity performance (protection from fire and smoke) whilst reducing transfer of dangerous radiant heat.
Class E : Fire-resistant glass which remains transparent in the event of fire offers protection from fire and smoke event of a fire (integrity only performance). But does not reduce the transfer of dangerous radiant  heat in the event of a fire.

How it works
Pilkington Pyrostop® and Pilkington Pyrodur® are clear, multi-layered fire-resistant glasses made of clear or extra clear float glass, laminated with special transparent intumescent interlayers. When exposed to fire, the pane facing the flames fractures but remains in place, and the interlayer immediately foams up to form a thick, resilient and tough insulating shield that absorbs the energy of the blaze. This takes place at relatively modest temperatures around 120°C, such that protection is provided right from the early stages of a fire.
