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.

Good candidates for blast-resistant glazing:

Embassies, courts and police premises
Offices in city centres and near potential targets
Government, council and civic buildings
Laboratories and industrial sites with process risks

Before the glass is ordered

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.

Glazing rules in Northern Ireland

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.

Fire-rated glass is different

Glass in fire doors and fire screens must be fire-rated glass tested within that system, under Technical Booklet E and, for non-domestic premises, the Fire and Rescue Services (Northern Ireland) Order 2006 and Fire Safety Regulations (Northern Ireland) 2010. Security and laminated glass are not fire-rated unless the product is tested for it.

Blast-resistant glazing in Downpatrick: questions

Can you survey in Downpatrick and nearby towns?

Yes. Surveys in Downpatrick, Comber and Newtownards 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.

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.

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.
