Blast-resistant glazing in Muswell Hill

What should blast-resistant glazing cost in Muswell Hill?

Budget £450 to £1,495 plus VAT (£540 to £1,794 inc VAT) per m² for blast-resistant glazing in Muswell Hill, 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.

What goes into blast-resistant glazing

Glazing classed to BS EN 13541 or tested to ISO 16933 and 16934
Blast-resistant net curtains as a fragment-catching layer
Work planned from the threat assessment and engineer's design
Anti-shatter film with edge-retention systems for existing windows
Laminated glass with thick or stiff interlayers
Deep-bite frames and structural silicone or mechanical retention

Fitting in Muswell Hill and nearby

Greater London has every kind of glazing, from Georgian sashes and Victorian bays in conservation areas to high-street shopfronts, office curtain walling and new-build flats.

Good candidates for blast-resistant glazing:

Government, council and civic buildings
Laboratories and industrial sites with process risks
Transport hubs, venues and stadium frontages
Offices in city centres and near potential targets

Before the glass is ordered

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.

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.

Glazing rules in England

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.

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 Muswell Hill: questions

Can you survey in Muswell Hill and nearby towns?

Yes. Surveys in Muswell Hill, Wood Green and Archway 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.

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.
