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 glazing 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 120 whilst providing unobstructed open view by using very slim vertical butt-joints between the glass units.

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 up to EI 120. 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.
