Blast-resistant glazing in Deeside

What should blast-resistant glazing cost in Deeside?

As a guide, allow £450 to £1,495 plus VAT (£540 to £1,794 inc VAT) per m² for blast-resistant glazing in Deeside, supplied and fitted. Size, glass makeup, access and frame condition move the price, which is confirmed in writing after the free survey.

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.

Before the glass is ordered

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.

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.

Glazing rules in Wales

Wales

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.

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.

Blast-resistant glazing in Deeside: questions

Can you survey in Deeside and nearby towns?

Yes. Surveys in Deeside, Hawarden and Buckley are booked around installer availability.

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.

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.
