Pilkington Pyrodur®

Fire-resistant glass for integrity and reduced heat radiation


Pilkington Pyrodur® is a clear laminated fire-resistant and safety glass (in thickness from 9 mm) designed to provide basic integrity fire protection, but also offering limitation of radiant heat transfer. It relies on the same generic technology as Pilkington Pyrostop® comprising fewer interlayers. 


Suitable for internal and external applications where fire-resistant glasses are required to provide integrity and a prescribed level of insulation up to class EW 60. Pilkington Pyrodur® is available in single and double glazed form, for use with steel, aluminium, softwood and hardwood timber frames. 

It can be combined with functional glasses to produce a wide range of products for numerous applications. 
Pilkington Pyrodur® is particularly suited for use in doors, screens and partitions where lightweight, narrow profiles are important and ease of glazing is a priority. Further applications include insulating glass units in façades and roof glazing (special compositions for inclined applications).


  • Provides proven integrity for up to 60 minutes when used in a suitable, tested glazing system, restricting the spread of flames, smoke and hot gases
  • It relies on the same generic technology as Pilkington Pyrostop® comprising thinner and fewer interlayers
  • Special clear intumescent interlayers, reacting to form a rigid, opaque, visual barrier to flames, helping to reduce panic and fear during evacuation of the building
  • Added benefit of reducing the transmission of conductive and radiant heat from the fire
  • Totally clear, unobstructed vision
  • Provides effective noise control
  • Can provide impact safety performance, dependent upon thickness
  • Can be combined with other functional glasses for greater flexibility in applications
  • Available in different thicknesses and compositions for internal or external applications
  • Available in monolithic or insulating glass unit form
