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.

Getting the right glass for your building
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.
What the rules say in Northern Ireland
Planning permission
Planning in Northern Ireland is handled by the eleven councils, which decide whether a new or altered shopfront needs permission; changing the glass in an existing frame usually does not. Bollards or barriers on a public footway need consent from the Department for Infrastructure's roads service.
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 County Armagh: questions
Which towns in County Armagh do you cover?
We can arrange work anywhere in County Armagh, including Armagh, Craigavon, Lurgan and Portadown.
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.
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.
