Toughened safety glass in March

What should toughened safety glass cost in March?

Budget £114 to £414 including VAT (£95 to £345 plus VAT) per pane for toughened safety glass in March, 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.

Fitting in March and nearby

March is about 14 miles from Peterborough, the main centre for Cambridgeshire. We can survey and fit across the PE15 district and in nearby places such as Wisbech and Peterborough.

Cambridgeshire has listed college streets and shopfronts in Cambridge and Ely, Peterborough's Victorian terraces and modern retail, and science-park offices with large glazed facades.

Good candidates for toughened safety glass:

Glazed doors and side panels
Frameless office partitions and doors
Balustrades in a laminated toughened makeup
Shower screens and splashbacks

Before the glass is ordered

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.

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.

Replacing glass in an existing frame

Replacing only the glass or sealed unit in an existing frame is generally treated as a repair in England rather than notifiable building work. Replacing a whole window or door is notifiable and is normally certified through a competent person scheme or approved by building control. Either way, new glass in a critical location should still be safety glass.

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 March: questions

Which areas near March do you cover?

We can arrange work in March and in nearby Wisbech (8 miles), Peterborough (14 miles) and King's Lynn (19 miles). Dates depend on 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.

Is toughened glass a security glass?

No. Toughened glass is strong and breaks safely, but once broken the pane falls out and leaves the opening clear. For security, choose laminated glass or a unit with a laminated pane.

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.
