As can be seen from the attachment/image below, EN1063 BR4 Glass is available in 2 spall variants, no spall (NS) and spall allowed (SA),

Both options may be available in fire rated versions dependent on Certifire availability.  Alternatively a dual glazed system can be utilised to offer fire rated and bullet resistant properties.  

The fire rated variants can be incorporated into our Fire Resistant Windows or Security and Counters to fit your projects needs.

Alternatively if you require EN 1063 BR4 glazing only, this can be incorporated into our Bullet Resistant Windows or Bullet Resistant Doors, allowing a Vision Panel to be included in the design of the door.
