Getting the right glass for your building

Keep or replace frames

If the frames are sound, new glass is the cheaper upgrade. If they are failing, we will tell you so you can compare with new windows.

Laminated inner or both panes

A laminated inner pane suits most homes. Laminating both panes adds protection on hidden elevations.

What the rules say in England

England

Windows needed for escape

Approved Document B expects many habitable rooms in houses, particularly upstairs, to have an escape window with a clear opening of at least 0.33 m², at least 450 mm high and 450 mm wide, with the bottom of the opening no more than 1,100 mm above the floor. Changing the glass does not alter that, but locks, secondary glazing and film must not stop the window opening. Laminated glass is hard to break through, so escape always relies on the window opening.

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.

Security glass for home windows in Greater London: questions

Which towns in Greater London do you cover?

We can arrange work anywhere in Greater London, including Central London, Islington, Bexley, Barking and Archway, and in other towns across the area.

Do I need new windows to get security glass?

No. If your frames are in good condition, we replace just the glass with laminated units made to fit them.

Can you match my obscure bathroom glass?

We can usually match common obscure patterns, or fit a laminated obscure glass with a similar look.

Does replacing the glass need building regulations approval?

Replacing glass in an existing frame is generally treated as a repair. Replacing whole windows is controlled work: notifiable in England and Wales, and in Scotland and Northern Ireland the council's building control can say whether approval is needed. New glass in a critical location should still be safety glass.
