Blast-resistant glazing in Hitchin: what will it cost?
Our guide range for blast-resistant glazing in Hitchin 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 you can specify
- Anti-shatter film with edge-retention systems for existing windows
- 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
- Glazing classed to BS EN 13541 or tested to ISO 16933 and 16934

Getting the right glass for your building
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.
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.
What the rules say in 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 Hitchin: questions
Do you cover Letchworth Garden City as well as Hitchin?
Yes. As well as Hitchin, we can arrange surveys in nearby Letchworth Garden City, Stevenage and Luton. Dates depend on 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.
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.
Does blast glazing affect fire doors and fire screens?
Glass in fire-rated doors and screens must stay fire-rated glass tested in that system. Blast measures there need fire-rated products or a specialist design, never a swap to plain laminated glass.
