Pilkington Pyrostop® - Laminated fire protection glass for integrity and insulation. Protects against heat, flames and hot gases at the highest level.

• A clear, laminated fully insulating fire-resistant and safety glass that offers the highest levels of fire protection, limiting the transmission of conductive and radiant heat, while maximising the available levels of natural light and visibility.
• Successfully tested in many fire doors, partitions and façade systems, covering vertical, horizontal and inclined glazing situations all over the world.
• Provides impact protection of up to Grade A, AS1288 (depending on thickness)
  

Pilkington Pyrostop® is a clear, multi-layered fire-resistant glass made of clear or extra clear float glass (Pilkington Optifloat™, Pilkington Optiwhite™), 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 only modest temperatures of around 120°C, so that protection is provided right from the early stages of a fire. The resilient sandwich structure of Pilkington Pyrostop® ensures that the glass stays in place and continues to act as an insulating fire-resistant wall for the required time periods, as defined in the relevant test standard.

Pyrostop® is ideal when a complete, physically robust fire protection shield is desired in combination with high quality through vision and high quality natural lighting, typical of normal glazing.

Pilkington Pyrostop® complies with the very precise temperature criteria defined in European test standards, ISO test standards, and AS1530.4. It turns opaque during fire providing both the integrity requirements of a barrier to hot gases and flames, as well as very effective insulation from the heat of a blaze.
