Blast-resistant glazing in Bletchley

Blast-resistant glazing in Bletchley: what will it cost?

Our guide range for blast-resistant glazing in Bletchley is £450 to £1,495 plus VAT (£540 to £1,794 inc VAT) per m², including fitting. The survey is free for new installations and your fixed price follows in writing.

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 goes into blast-resistant glazing

Manufacturer's test evidence supplied with your quote
Anti-shatter film with edge-retention systems for existing windows
Glazing classed to BS EN 13541 or tested to ISO 16933 and 16934
Work planned from the threat assessment and engineer's design
Laminated glass with thick or stiff interlayers
Deep-bite frames and structural silicone or mechanical retention

Fitting in Bletchley and nearby

Surveys in Bletchley (MK3) are booked around installer availability. We also cover nearby Milton Keynes (3 miles), Leighton Buzzard (6 miles) and Ampthill (10 miles).

Milton Keynes' glass-fronted shopping centre and business districts contrast with Buckinghamshire's older towns, where Aylesbury, Amersham and Marlow keep many period shopfronts.

Typical settings for blast-resistant glazing:

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

Getting the right glass for your building

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.

What the rules say in England

England

Fire-rated glass is different

Glass in fire doors, fire screens and protected escape routes has to be fire-rated glass tested as part of that door or screen system, under Approved Document B and the fire safety duties of the building's responsible person. Laminated and security glass are not fire-rated unless the product says so. Where a pane needs both fire and security performance, it must be a product tested for both.

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.

Blast-resistant glazing in Bletchley: questions

Can you survey in Bletchley and nearby towns?

Yes. Surveys in Bletchley, Milton Keynes and Leighton Buzzard 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.

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.

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.
