Blast-resistant glazing in Risca

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

Our guide range for blast-resistant glazing in Risca is £450 to £1,495 plus VAT (£540 to £1,794 inc VAT) per m², including fitting. The survey is free for new installations and your fixed price follows in writing.

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.

Typical settings for blast-resistant glazing:

Offices in city centres and near potential targets
Government, council and civic buildings
Laboratories and industrial sites with process risks
Transport hubs, venues and stadium frontages

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.

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 Wales

Wales

Planning permission

In Wales the local planning authority decides whether a new or altered shopfront needs planning permission. Replacing glass in an existing frame usually does not, because the outside of the building looks much the same. Bollards or barriers on the pavement need consent from the highway authority, normally the council.

Fire-rated glass is different

Glass in fire doors and fire screens must be fire-rated glass tested as part of that door or screen, under Approved Document B for Wales and, in non-domestic premises, the Regulatory Reform (Fire Safety) Order 2005. Security and laminated glass are not fire-rated unless the product is tested for it, so the two cannot simply be swapped.

Blast-resistant glazing in Risca: questions

Which areas near Risca do you cover?

We can arrange work in Risca and in nearby Newport (5 miles), Cwmbran (5 miles) and Caerphilly (6 miles). 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.

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.

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.
