What should blast-resistant glazing cost in Devon?
As a guide, allow £450 to £1,495 plus VAT (£540 to £1,794 inc VAT) per m² for blast-resistant glazing in Devon, 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 goes into blast-resistant glazing
- Manufacturer's test evidence supplied with your quote
- Laminated glass with thick or stiff interlayers
- Blast-resistant net curtains as a fragment-catching layer
- Sealed units with a laminated inner pane
- Glazing classed to BS EN 13541 or tested to ISO 16933 and 16934
- Work planned from the threat assessment and engineer's design
Covering Devon
We can arrange surveys and fitting anywhere in Devon, including Plymouth and Exeter. Dates depend on installer availability. Choose your town below for local details.
Devon spans Exeter's Georgian and post-war centre, Plymouth's rebuilt 1950s shopping streets and waterfront offices, and seaside towns where sea air is hard on window frames and seals.
Good candidates for blast-resistant glazing:
- Transport hubs, venues and stadium frontages
- Government, council and civic buildings
- Laboratories and industrial sites with process risks
- Embassies, courts and police premises

Before the glass is ordered
Fragment hazard
Some designs accept that glass will break but keep it in place; others allow controlled failure into a catching system. Both aim to stop flying shards.
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.
Glazing rules in 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 Devon: questions
Which towns in Devon do you cover?
We can arrange work anywhere in Devon, including Plymouth, Exeter, Paignton, Torquay and Newton Abbot, and in other towns across the area.
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.
