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.

Offices in city centres and near potential targets

What to think about first

New glazing or retrofit

New facades can be designed as a full tested system. Existing buildings often get film with edge retention, internal secondary glazing or curtains instead.

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.

Consents and safety: England

Listed buildings and conservation areas

In England, listed building consent from the council may be needed to replace historic glass such as crown or cylinder glass, or to alter glazing bars, sashes and frames. Historic England publishes guidance on traditional windows. Secondary glazing and window film are often easier to agree because they can be removed later, but the council's conservation officer makes the decision.

Glazing in workplaces

Regulation 14 of the Workplace (Health, Safety and Welfare) Regulations 1992 requires windows and transparent surfaces in walls, partitions, doors and gates to be of safety material or protected against breakage where health or safety makes that necessary, and to be marked so people notice them. The employer or the person in control of the premises decides what is needed through their risk assessment.

Blast-resistant glazing in Oswestry: questions

Can you survey in Oswestry and nearby towns?

Yes. Surveys in Oswestry, Shrewsbury and Chester are booked around installer availability.

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.

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.
