Pilkington Pyrostop® Line

Pilkington Pyrostop® Line

Fire-resistant glass solutions for butt-jointed integrity and insulation performance.


The Pilkington Pyrostop® Line Range stands for reliable and sustainable solutions for butt-jointed glazings for internal applications where additional vertical framing between glass panes are not an option.
Today two different types offer a variety of solutions designed to meet integrity and insulation fire resistance performance up to EI 60 whilst providing unobstructed open view by using very slim vertical butt-joints between the glass units.

Flush design meets structural integrity

Pilkington Pyrostop® Line Triple - as a Triple Glass Unit - has been designed for use in flush glazed partitions for internal applications and is an sustainable and long-lasting solution complying with additional mechanical load requirements. It is a robust performer comprising Pilkington Pyrostop® and two toughened glass panes either side combined into a triple  Insulating Glass Unit whilst offering a wide choice of colours and designs.

Flush design meets panoramic view

Pilkington Pyrostop® Line is the monolithic version for butt-jointed vertical glazing for internal application with integrity and insulation fire resistance performance. It is based on the same generic tried and tested technology as Pilkington Pyrostop® and offers the same fire resistance performance allowing panoramic view partitions with very slim butt-joints of only approx. 5 mm width.
