Blast-resistant glazing in Alloa

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

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

Scotland

Glazing in workplaces

Regulation 14 of the Workplace (Health, Safety and Welfare) Regulations 1992 applies in Scotland. Windows and transparent surfaces in walls, partitions, doors and gates must be of safety material or protected against breakage where health or safety requires it, and marked so people see them. The duty holder's risk assessment decides where.

Planning permission

Under the Scottish planning system the council decides whether a new or altered shopfront needs planning permission; changing the glass in an existing frame usually does not. Bollards or barriers in a road or footway need consent from the roads authority, which is normally the council.

Blast-resistant glazing in Alloa: questions

Can you survey in Alloa and nearby towns?

Yes. Surveys in Alloa, Stirling and Grangemouth 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.

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.
