Pilkington Pyrostop is a fire-rated and impact safety-rated glazing
material. Pilkington Pyrostop also blocks heat, protecting people and
valuables on the non-fire side of the glass during a fire. It is listed for
use in doors, sidelites, transoms, borrowed lites and wall applications
with a fire rating of up to 2 hours.
Where needed, Pilkington Pyrostop can double as security glazing,
offering the same protection as bullet resistant glass (without the
flammability of polycarbonate).
Pilkington Pyrodur is a 5/16" (7 mm) thick fire-rated and impact
safety-rated glazing material. It is based on the same advanced
technology as Pilkington Pyrostop, combining glass and a special
interlayer that turns to foam during a fire. Pilkington Pyrodur is listed
for use in interior doors with a fire rating requirement of 20 minutes.
