What should blast-resistant glazing cost in Barnes?

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.
Glass and fitting options
- Blast-resistant net curtains as a fragment-catching layer
- Anti-shatter film with edge-retention systems for existing windows
- Sealed units with a laminated inner pane
- Laminated glass with thick or stiff interlayers
- Deep-bite frames and structural silicone or mechanical retention
- Work planned from the threat assessment and engineer's design

Before the glass is ordered
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.
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
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.
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 Barnes: questions
Can you survey in Barnes and nearby towns?
Yes. Surveys in Barnes, Chiswick and Putney are booked around 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.
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.
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.
