What should blast-resistant glazing cost in Dorchester?
As a guide, allow £450 to £1,495 plus VAT (£540 to £1,794 inc VAT) per m² for blast-resistant glazing in Dorchester, 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.

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.
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.
Glazing rules in England
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.
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.

Blast-resistant glazing in Dorchester: questions
Which areas near Dorchester do you cover?
We can arrange work in Dorchester and in nearby Weymouth (7 miles), Bridport (14 miles) and Yeovil (18 miles). 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.
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.
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.
