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

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.

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: England

England

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.

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.

Blast-resistant glazing in Derbyshire: questions

Which towns in Derbyshire do you cover?

We can arrange work anywhere in Derbyshire, including Derby, Chesterfield, Long Eaton, Ilkeston and Swadlincote, and in other towns across the area.

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.

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.

Who decides what level of protection we need?

Your security adviser, insurer or a blast engineer, based on a threat and risk assessment. Government guidance from the National Protective Security Authority covers the approach.
