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.
Choices you can make
- Anti-shatter film with edge-retention systems for existing windows
- Sealed units with a laminated inner pane
- Blast-resistant net curtains as a fragment-catching layer
- Manufacturer's test evidence supplied with your quote
- Laminated glass with thick or stiff interlayers
- Deep-bite frames and structural silicone or mechanical retention
Fitting in Derby and nearby
We can arrange blast-resistant glazing across Derby, the main centre for Derbyshire, and in nearby towns including Belper, Ilkeston and Heanor.
Derbyshire combines Derby's Victorian terraces and city-centre shops with gritstone villages and spa towns in the Peak District, where Bakewell and Buxton have conservation areas.
This glazing suits:
- Government, council and civic buildings
- Embassies, courts and police premises
- Offices in city centres and near potential targets
- Transport hubs, venues and stadium frontages
Questions we will ask at the survey
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.
Building regulations and safety in England
Listed buildings and conservation areas
In England, listed building consent from the council may be needed to replace historic glass such as crown or cylinder glass, or to alter glazing bars, sashes and frames. Historic England publishes guidance on traditional windows. Secondary glazing and window film are often easier to agree because they can be removed later, but the council's conservation officer makes the decision.
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.

Blast-resistant glazing in Derby: questions
Which areas near Derby do you cover?
We can arrange work in Derby and in nearby Belper (7 miles), Ilkeston (8 miles) and Heanor (8 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.
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.
