Blast-resistant glazing in Barry

How much should I budget for blast-resistant glazing in Barry?

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

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.

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.

Consents and safety: Wales

Wales

Listed buildings and conservation areas

Listed buildings in Wales need listed building consent from the local planning authority for works that affect their character, which can include replacing historic glass, glazing bars or sashes. Cadw advises on the historic environment in Wales. Reversible options such as secondary glazing are often easier to agree, but the council decides.

Fire-rated glass is different

Glass in fire doors and fire screens must be fire-rated glass tested as part of that door or screen, under Approved Document B for Wales and, in non-domestic premises, the Regulatory Reform (Fire Safety) Order 2005. Security and laminated glass are not fire-rated unless the product is tested for it, so the two cannot simply be swapped.

Blast-resistant glazing in Barry: questions

Can you survey in Barry and nearby towns?

Yes. Surveys in Barry, Penarth and Cardiff are booked around installer availability.

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.

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.

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.
