Blast-resistant glazing in Darlington

Blast-resistant glazing in Darlington: what will it cost?

As a guide, allow £450 to £1,495 plus VAT (£540 to £1,794 inc VAT) per m² for blast-resistant glazing in Darlington, supplied and fitted. Size, glass makeup, access and frame condition move the price, which is confirmed in writing after the free 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.

Embassies, courts and police premises
Laboratories and industrial sites with process risks

Getting the right glass for your building

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.

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

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 Darlington: questions

Do you cover Newton Aycliffe as well as Darlington?

Yes. As well as Darlington, we can arrange surveys in nearby Newton Aycliffe, Stockton-on-Tees and Thornaby-on-Tees. Dates depend on installer availability.

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.

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.

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.
