Pilkington Pyrodur®

Using the same technology as Pilkington Pyrostop®, Pilkington Pyrodur® is tried and tested against fire and hot gases. 

Pilkington Pyrodur® is widely used and specified in a range of softwood and hardwood timber. Offering up to 60 mins integrity, Pilkington Pyrodur® can combine impact resistance (BS EN 12600) up to Class 1(B)1 and penetration resistance (BS EN 356) to classification P(1)A , which is a requirement in Approved Document Q and recommended in Secured by Design.

In the event of fire, Pilkington Pyrodur® turns opaque providing both the integrity requirements of a barrier to hot gases and flames. As such, Pilkington Pyrodur® complies with British, European and ISO test standards.
