Blast-resistant glazing in Tiverton

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.

Choices you can make

Sealed units with a laminated inner pane
Laminated glass with thick or stiff interlayers
Glazing classed to BS EN 13541 or tested to ISO 16933 and 16934
Work planned from the threat assessment and engineer's design
Blast-resistant net curtains as a fragment-catching layer
Anti-shatter film with edge-retention systems for existing windows

Getting the right glass for your building

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.

What the rules say in England

England

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.

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 Tiverton: questions

Which areas near Tiverton do you cover?

We can arrange work in Tiverton and in nearby Exeter (12 miles), Taunton (19 miles) and Exmouth (20 miles). Dates depend on installer availability.

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.

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.
