Blast-resistant glazing in Essex

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

Guide prices for blast-resistant glazing in Essex 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

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.

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

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.

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 Essex: questions

Which towns in Essex do you cover?

We can arrange work anywhere in Essex, including Southend-on-Sea, Basildon, Colchester, Chelmsford and Harlow, and in other towns across the area.

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.

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.
