Blast-resistant glazing in Northampton

How much does blast-resistant glazing cost in Northampton?

Budget £450 to £1,495 plus VAT (£540 to £1,794 inc VAT) per m² for blast-resistant glazing in Northampton, supplied and fitted. Larger panes, thicker makeups and difficult access cost more; the price is fixed in writing after the 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.

Fitting in Northampton and nearby

Surveys in Northampton (NN1) are booked around installer availability, as they are in nearby Wellingborough (9 miles) and Daventry (12 miles).

Northamptonshire mixes Northampton's town-centre retail and Victorian shoe-trade streets with newer estates around Corby and Wellingborough and stone villages towards Oundle.

Typical places for blast-resistant glazing:

Transport hubs, venues and stadium frontages
Laboratories and industrial sites with process risks
Government, council and civic buildings
Embassies, courts and police premises

Things to decide before you order

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.

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.

Rules that apply in England

England

Listed buildings and conservation areas

In England, listed building consent from the council may be needed to replace historic glass such as crown or cylinder glass, or to alter glazing bars, sashes and frames. Historic England publishes guidance on traditional windows. Secondary glazing and window film are often easier to agree because they can be removed later, but the council's conservation officer makes the decision.

Glazing in workplaces

Regulation 14 of the Workplace (Health, Safety and Welfare) Regulations 1992 requires windows and transparent surfaces in walls, partitions, doors and gates to be of safety material or protected against breakage where health or safety makes that necessary, and to be marked so people notice them. The employer or the person in control of the premises decides what is needed through their risk assessment.

Blast-resistant glazing in Northampton: questions

Can you survey in Northampton and nearby towns?

Yes. Surveys in Northampton, Wellingborough and Daventry 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.
