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.

Things to decide before you order
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.
Rules that apply in 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.
Listed buildings and conservation areas
Listed buildings in Wales need listed building consent from the local planning authority for works that affect their character, which can include replacing historic glass, glazing bars or sashes. Cadw advises on the historic environment in Wales. Reversible options such as secondary glazing are often easier to agree, but the council decides.

Blast-resistant glazing in Gwynedd: questions
Which towns in Gwynedd do you cover?
We can arrange work anywhere in Gwynedd, including Bangor, Caernarfon, Holyhead and Pwllheli.
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.
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.
