Blast-resistant glazing in Portsmouth: what will it cost?
Guide prices for blast-resistant glazing in Portsmouth are £450 to £1,495 plus VAT (£540 to £1,794 inc VAT) per m² for supply and fitting. We confirm a fixed price in writing after a free survey, before any glass is ordered.
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
- Blast-resistant net curtains as a fragment-catching layer
- Manufacturer's test evidence supplied with your quote
- Deep-bite frames and structural silicone or mechanical retention
- Work planned from the threat assessment and engineer's design
- Sealed units with a laminated inner pane
- Laminated glass with thick or stiff interlayers

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.
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.
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.
Planning permission
Changing the glass in an existing window or shopfront does not usually need planning permission, because the building looks much the same afterwards. A new or altered shopfront, or security features added to the outside of a building, may need planning permission from the council. Bollards or barriers on the pavement need the highway authority's consent, which is normally the council.

Blast-resistant glazing in Portsmouth: questions
Do you cover Gosport as well as Portsmouth?
Yes. As well as Portsmouth, we can arrange surveys in nearby Gosport, Fareham and Havant. Dates depend on installer availability.
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.
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.
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.
