Toughened safety glass in Barnet

What should toughened safety glass cost in Barnet?

Budget £114 to £414 including VAT (£95 to £345 plus VAT) per pane for toughened safety glass in Barnet, supplied and fitted. Larger panes, thicker makeups and difficult access cost more; the price is fixed in writing after the 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.

Clear, tinted, obscure, low-iron and sandblasted finishes

Balustrades in a laminated toughened makeup

Before the glass is ordered

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.

Heat soaking

Rare nickel sulphide inclusions can make toughened glass break without warning. Heat soaking reduces the risk and is worth specifying for large, high or overhead panes.

Glazing rules in England

England

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.

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.

Toughened safety glass in Barnet: questions

Can you survey in Barnet and nearby towns?

Yes. Surveys in Barnet, Potters Bar and Borehamwood are booked around installer availability.

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.

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.

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.
