Pilkington Pyrostop^® is a clear, multi-laminated fully insulating fire-resistant safety glass that offers the highest level of fire protection, effectively blocking the transmission of conductive and radiant heat, while maximising the transmission of natural light and transparency.

The consistently high performance of Pilkington Pyrostop^® in fire tests and real fires is an attribute of its well-researched and refined multilayer intumescent technology.

Several float glass layers are combined with special transparent fire protection interlayers. In case of fire the glass pane facing the fire cracks and the first interlayer foams up and turns opaque, blocking the passage of fire and absorbing its energy.

This continues progressively layer by layer providing a capacity by design to withstand intense fires for extended periods of time.

The glass unit remains intact, heat is effectively blocked, and the robust fire and smoke resistance performance is maintained for the entire period of exposure to fire in accordance with the required classification.

Pilkington Pyrostop^® is designed for interior and exterior use where thermal insulation is required in the case of fire up to class EI 180. It is suitable for use with steel, aluminium and timber frames in monolithic form or insulating glass units.

Pilkington Pyrostop^® is ideal for use in transparent fire walls, windows (special application), doors, screens, partitions and façades as well as for horizontal applications (roof and inclined glazing).

Product Combinations

Pilkington Pyrostop^® is an innovative fire-resistant glass that can offer a variety of additional properties over and above its primary function. In addition to protection against fire, this glass can be equipped with other functions that fulfil the requirements of modern buildings. These include thermal insulation to increase energy efficiency, solar control for a pleasant indoor climate and sound insulation for a quiet atmosphere. Self-cleaning surfaces make maintenance easier, while safety and protection functions protect both people and property from damage. Integrated alarms and design options extend the range of applications, and special privacy options such as internal blinds ensure privacy and comfort. These multifunctional glasses thus combine maximum security with additional benefits and design freedom.
