Technical Glass Products announced that Pilkington Pyrostop glass with 3M SCLARL 400 film now offers the advantages of security as well as fire protection.
Pyrostop has received a Level III bullet resistance rating, indicating it can stop a .44 Magnum bullet.
With increased emphasis being given to security issues in construction, concerns about violence and gunfire often overlap with concerns about fire. Yet most types of protective glazing are highly flammable, due to their composition. During a fire, they can generate tremendous mounts of flames and smoke that can cause further damage to life and property.
Pyrostop is considered a glass firewall. While other fire-rated glass products contain the spread of flame and smoke, Pyrostop is designed for use I location such as stairwells and elevator lobbies where it is also critical to control the transfer of heat produced by a fire.
