Blast-resistant glazing in Grantham

What is the price of blast-resistant glazing in Grantham?

Our guide range for blast-resistant glazing in Grantham 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.

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.

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.

Building regulations and safety in England

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 Grantham: questions

Which areas near Grantham do you cover?

We can arrange work in Grantham and in nearby Sleaford (11 miles), Newark-on-Trent (13 miles) and Melton Mowbray (14 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.

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.
