Blast-resistant glazing in Merseyside

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

Expect £450 to £1,495 plus VAT (£540 to £1,794 inc VAT) per m² for blast-resistant glazing in Merseyside. The written quote names the glass makeup, the price and the lead time before you commit.

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

England

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.

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 Merseyside: questions

Which towns in Merseyside do you cover?

We can arrange work anywhere in Merseyside, including Liverpool, Birkenhead, St Helens, Southport and Wallasey, and in other towns across the area.

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.

Does blast glazing affect fire doors and fire screens?

Glass in fire-rated doors and screens must stay fire-rated glass tested in that system. Blast measures there need fire-rated products or a specialist design, never a swap to plain laminated glass.

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.
