Before the glass is ordered

Which pane is laminated

Laminating the inner pane is the usual security choice. Laminating both panes adds protection on high-risk elevations.

Energy performance

Choosing low-E glass, argon and warm-edge spacers keeps the window as efficient as possible, often better than the unit being replaced.

Glazing rules in Northern Ireland

Northern Ireland

Listed buildings and conservation areas

Listed buildings in Northern Ireland need listed building consent from the council for works affecting their character, which can include historic glass and sash windows. The Department for Communities' Historic Environment Division advises on these cases. Conservation areas bring extra scrutiny of shopfronts and external changes.

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 double-glazed units in County Down: questions

Which towns in County Down do you cover?

We can arrange work anywhere in County Down, including Banbridge, Bangor, Comber, Downpatrick and Holywood, and in other towns across the area.

How long do new units take?

Units are made to order after the survey. Lead times vary with glass type and size, and we confirm them when we quote.

Do security units reduce noise?

Laminated glass already damps sound better than plain glass, and acoustic interlayers improve it further, which helps on busy roads.

Will a laminated unit be heavier?

A little. A laminated pane weighs about the same as a solid sheet of the same thickness. On large opening sashes we check hinges and friction stays.
