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.

Before the glass is ordered

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.

Who sets the level

The design pressure comes from a threat and risk assessment by a security adviser or blast engineer, not from the glass supplier.

Glazing rules in England

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.

Fire-rated glass is different

Glass in fire doors, fire screens and protected escape routes has to be fire-rated glass tested as part of that door or screen system, under Approved Document B and the fire safety duties of the building's responsible person. Laminated and security glass are not fire-rated unless the product says so. Where a pane needs both fire and security performance, it must be a product tested for both.

Blast-resistant glazing in Gosport: questions

Can you survey in Gosport and nearby towns?

Yes. Surveys in Gosport, Portsmouth and Fareham are booked around installer availability.

Is blast film enough on its own?

Film helps hold glass together but works much better when the film is anchored to the frame so the whole pane cannot fly in. Plain film without retention offers less.

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.
