Fire protection Units

Provide you with integrity/insulation and protection from radiation.
Plus passive protection from the effects of fire for up to 180 minutes (product dependant).


A range of fire-resistant glass units are available from Pilkingon Plyglass offering varying levels of protection, which are measured in terms of:

  • Integrity - the time the glass remains intact in a fire.
  • Insulation - the amount the glass will limit the temperature rise on the non-fire side. 
It should be noted that fire-resistant glass should always be specified as part of a complete glazing system, and installation carried out by specialists in order to ensure it achieves its expected fire performance.

Pilkington Pyrodur® Units 
These products use laminated intumescent layers to combine integrity and insulation for a short period of time in a completely clear glass. In a fire the clear interlayer foams to provide an opaque barrier, thus reducing fear and panic during evacuation.

  • Offers 30 and 60 minutes integrity, with full insulation for a short period of time, in a 10 mm thickness product.
  • Restricts flames and hot gases.
  • Turns opaque in a fire.
  • Grades available for internal and external applications.
  • Tested and approved with a wide range of fire-resistant framing materials, glazing gaskets and sealants.
  • Impact safety performance up to Class 1(B)1 BS EN 12600
  • Tried and successfully tested in a wide range of applications, including the Certifire Scheme.
  • The Pilkington range of fire-resistant glass units can be combined with other functional glass types.
