Toughened safety glass in Grantham

Toughened safety glass in Grantham: what will it cost?

As a guide, allow £114 to £414 including VAT (£95 to £345 plus VAT) per pane for toughened safety glass in Grantham, supplied and fitted. Size, glass makeup, access and frame condition move the price, which is confirmed in writing after the free survey.

Toughened safety glass is ordinary glass that has been heated and rapidly cooled so its surface is held in compression, making it four to five times stronger than annealed glass of the same thickness. If it does break, it shatters into small, relatively blunt pieces instead of sharp shards, which is why it is used in doors, low-level panes and frameless partitions.

Getting the right glass for your building

Toughened or laminated

Toughened gives strength and safe breakage. Laminated gives safe breakage and stays in place, which is what security needs. Many doors use both in one sealed unit.

Barriers and balustrades

Glass that acts as a barrier usually needs a laminated toughened makeup so it stays in place if one ply breaks.

What the rules say in England

England

Safety glass in critical locations

In England, section 5 of Approved Document K treats glazing in doors and in side panels within 300 mm of a door edge, from floor level up to 1,500 mm, and any other glazing below 800 mm, as a critical location. Glass there should break safely, be robust, or be guarded. Laminated or toughened glass meeting BS EN 12600 class 3 is the usual answer, rising to class 2 for door and side-panel panes wider than 900 mm.

Fire-rated glass is different

Glass in fire doors, fire screens and protected escape routes has to be fire-rated glass tested as part of that door or screen system, under Approved Document B and the fire safety duties of the building's responsible person. Laminated and security glass are not fire-rated unless the product says so. Where a pane needs both fire and security performance, it must be a product tested for both.

Toughened safety glass in Grantham: questions

Can you survey in Grantham and nearby towns?

Yes. Surveys in Grantham, Sleaford and Newark-on-Trent are booked around installer availability.

Why did my toughened glass break on its own?

Occasionally a tiny nickel sulphide inclusion or edge damage causes spontaneous breakage. Heat-soak tested glass reduces the risk for large or high panes.

Where must safety glass be used?

In critical locations: in England, Approved Document K covers glazing in and beside doors up to 1,500 mm from the floor and other glazing below 800 mm; Wales has the same idea in its Approved Document N, Scotland in standard 4.8 and Northern Ireland in Part V. Glass there must be safety glass or protected.

How can I tell if glass is toughened?

Look for a permanent mark etched in a corner naming the standard. Polarised sunglasses can also show faint patterns in toughened glass. We can check during the survey.
