As a guide, allow £450 to £1,495 plus VAT (£540 to £1,794 inc VAT) per m² for blast-resistant glazing in County Londonderry, 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.

What to think about first

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.

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: Northern Ireland

Northern Ireland

Glazing in workplaces

The Workplace (Health, Safety and Welfare) Regulations (Northern Ireland) 1993 contain an equivalent requirement to Great Britain's: windows and transparent surfaces in walls, partitions, doors and gates must be of safety material or protected where health or safety requires it, and marked so they are apparent. The employer's risk assessment decides where.

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 Londonderry: questions

Which towns in County Londonderry do you cover?

We can arrange work anywhere in County Londonderry, including Coleraine, Derry, Limavady and Magherafelt.

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.

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.
