Getting the right glass for your building

Keep the design

Most decorative glass can be copied or rebuilt with a laminated backing pane, so the door looks the same.

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.

What the rules say in Northern Ireland

Northern Ireland

Replacing glass in an existing frame

Building regulations in Northern Ireland are administered by the eleven councils' building control services. Replacing only the glass in an existing frame is generally treated as a repair, while replacing whole windows or doors can be controlled work, so check with building control first. New glass in a critical location should be safety glass under Part V.

Safety glass in critical locations

In Northern Ireland, safety glazing is covered by Part V of the Building Regulations (Northern Ireland) 2012, with guidance in Technical Booklet V. It follows a critical-location approach similar to Great Britain, covering glazing in and beside doors and at low level. Laminated or toughened safety glass is the usual answer; building control at the council can confirm the detail.

Security glass for doors in County Londonderry: questions

Which towns in County Londonderry do you cover?

We can arrange work anywhere in County Londonderry, including Coleraine, Derry, Limavady and Magherafelt.

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.

Is toughened glass enough for a door?

It meets the safety rule but not the security need, because a broken toughened pane falls out. A laminated pane meets both.
