Things to decide before you order

Side panels too

Side panels within 300 mm of the door are critical locations as well, and a weak side panel is an easy way in. We usually do both together.

Composite door glass

Some composite doors use a cassette made by the door's maker. We check whether a laminated version is available before quoting.

Rules that apply 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.

Security glass for doors in Hertford: questions

Do you cover Hoddesdon as well as Hertford?

Yes. As well as Hertford, we can arrange surveys in nearby Hoddesdon, Welwyn Garden City and Hatfield. Dates depend on installer availability.

Can you keep my stained or leaded glass design?

Usually. We add a laminated pane behind the decorative glass inside the sealed unit, or have a matching unit made.

Does door glass have to be safety glass?

Yes. Glass in doors up to 1,500 mm from the floor, and in side panels within 300 mm of the door edge, counts as a critical location and needs safety glass or protection.

Can you replace glass in a composite door?

Often. Some composite doors take a standard unit; others use the maker's own cassette, which we source where possible.
