Blast-resistant glazing is laminated glass fitted in a frame and fixing system designed to stay in the opening, or fail safely, when hit by the pressure wave from an explosion. Its purpose is to stop glass becoming high-speed fragments, which cause most injuries in a blast, and it is designed from a threat assessment rather than chosen off the shelf.

What to think about first
Fragment hazard
Some designs accept that glass will break but keep it in place; others allow controlled failure into a catching system. Both aim to stop flying shards.
Frame and fixings
The frame must hold the glass and the fixings must hold the frame. Upgrading glass alone can move the failure to the frame.
Consents and safety: Northern Ireland
Listed buildings and conservation areas
Listed buildings in Northern Ireland need listed building consent from the council for works affecting their character, which can include historic glass and sash windows. The Department for Communities' Historic Environment Division advises on these cases. Conservation areas bring extra scrutiny of shopfronts and external changes.
Glazing in workplaces
The Workplace (Health, Safety and Welfare) Regulations (Northern Ireland) 1993 contain an equivalent requirement to Great Britain's: windows and transparent surfaces in walls, partitions, doors and gates must be of safety material or protected where health or safety requires it, and marked so they are apparent. The employer's risk assessment decides where.

Blast-resistant glazing in County Down: questions
Which towns in County Down do you cover?
We can arrange work anywhere in County Down, including Banbridge, Bangor, Comber, Downpatrick and Holywood, and in other towns across the area.
Does blast glazing affect fire doors and fire screens?
Glass in fire-rated doors and screens must stay fire-rated glass tested in that system. Blast measures there need fire-rated products or a specialist design, never a swap to plain laminated glass.
What does ER1 to ER4 mean?
They are explosion-pressure classes in BS EN 13541. Glass samples are tested in a shock tube, with higher classes meaning higher pressures. The class applies to the glass, so the frame must be designed to match.
Can existing windows be made blast-resistant?
They can often be improved. Anti-shatter film with an edge-retention system, laminated replacement glass in strengthened frames or internal secondary glazing can cut the flying-glass hazard, depending on the threat.
