Blast-resistant glazing in Enfield: what will it cost?
Budget £450 to £1,495 plus VAT (£540 to £1,794 inc VAT) per m² for blast-resistant glazing in Enfield, 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.
Choices you can make
- Laminated glass with thick or stiff interlayers
- Blast-resistant net curtains as a fragment-catching layer
- Work planned from the threat assessment and engineer's design
- Deep-bite frames and structural silicone or mechanical retention
- Manufacturer's test evidence supplied with your quote
- Glazing classed to BS EN 13541 or tested to ISO 16933 and 16934

Getting the right glass for your building
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.
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
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.
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 Enfield: questions
Which areas near Enfield do you cover?
We can arrange work in Enfield and in nearby Edmonton (2 miles), Tottenham (3 miles) and Wood Green (4 miles). Dates depend on 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.
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.
