Blast-resistant glazing in Bridport: what will it cost?
Guide prices for blast-resistant glazing in Bridport 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.

Getting the right glass for your building
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.
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.
What the rules say 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.
Fire-rated glass is different
Glass in fire doors, fire screens and protected escape routes has to be fire-rated glass tested as part of that door or screen system, under Approved Document B and the fire safety duties of the building's responsible person. Laminated and security glass are not fire-rated unless the product says so. Where a pane needs both fire and security performance, it must be a product tested for both.

Blast-resistant glazing in Bridport: questions
Do you cover Dorchester as well as Bridport?
Yes. As well as Bridport, we can arrange surveys in nearby Dorchester, Yeovil and Weymouth. Dates depend on installer availability.
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.
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.
