How it works

Today modern architecture favours transparency...

even far beyond the facade: the architects prefer natural light and open spaces to determine the design of large buildings right down to their structural core. Wherever these “open” concepts meet local construction and fire safety requirements for the protection of human life and property, transparent fire-resistant glazing comes into play. This allows modern, bright and open space design, as well as safety to be combined in a variety of multi functional systems.

Pilkington fire-resistant glass is represented in several hundred fully tested and approved glazing systems. This includes doors and partitions of various framing materials and designs, facades and roof glazing and more recently even the first fire-resistant sliding doors and windows.

How it works

Pilkington Pyrostop® and Pilkington Pyrodur® are clear, multi-layered fire-resistant glasses made of clear (Pilkington Optifloat™) or extra clear float glass (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 relatively modest temperatures around 120°C, such that protection is provided right from the early stages of a fire.
