Triple glazed bay and bow windows in Antrim
Homes in Antrim can have triple glazed bay and bow windows supplied and fitted, with surveys arranged across County Antrim including BT41.
Three- and five-light bays, structure checked and supported. A bay window projects out from the wall in angled sections; a bow window curves in more, shallower sections.
Winter light and glass choice in Antrim
On the shortest day, Antrim gets about 7 h 13 min of daylight and the midday sun reaches only about 12° above the horizon. Low winter sun means north-facing rooms here gain little solar heat, which is where triple glazing’s lower heat loss helps most.

Rules for bay and bow windows in Northern Ireland
In Northern Ireland, replacement windows must meet 1.6 W/m²K, or a Window Energy Rating of band C or better. Replacing windows or external doors does not need full plans or a building notice, but the work must still comply; enlarging an opening or other structural change needs building control approval.
Before ordering: Check with your council planning office before changing the style, material or size of windows or doors, and always for listed buildings, conservation areas and flats.
How it works
You will know exactly what you are buying: the quote states the unit build-up, frame, finish, fitting work and how Building Regulations compliance is handled. On fitting day each opening is replaced and closed up before the team moves on.
- Every opening measured, including escape and vent needs
- Frames rated for the weight of triple glass
- Old windows removed and taken away
- Each opening closed up the same day
Questions from Antrim
Can I change a bay to a flat window?
That is a structural and planning change, not a like-for-like replacement. Ask and we will explain what it involves.
Do bay windows need bay poles?
If the old frames carry load from above, yes. We check on survey and include support in the quote where needed.
How long does it take to get triple glazed bay and bow windows fitted in Antrim?
After the survey, typical manufacture time is 5 to 8 weeks, and most homes are fitted in 1 to 4 days.
Do I need permission for triple glazed bay and bow windows in Antrim?
In Northern Ireland, check with your council planning office before changing the style, material or size of windows, and always for listed buildings and flats. Check whether your street is in a conservation area or covered by an Article 4 direction before changing the style.
