Triple glazed fixed and picture windows in County Antrim
Homes across County Antrim, including Belfast, Lisburn and Ballymoney, can have triple glazed fixed and picture windows measured, made to order and fitted.

Rules in Northern Ireland
The rules for replacement windows in Northern Ireland are set by Technical Booklet F1 (2022): 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
Can a fixed window be the escape window?
No. An escape window must open. We keep or add an opening window where one is needed.
Is a picture window worth triple glazing?
Big panes lose a lot of heat and can feel cold to sit near. Triple glazing keeps the inner pane warmer, which makes the space by the window more comfortable.
Do fixed windows need trickle vents?
The room still needs ventilation. If the fixed window replaces one with vents, ventilation must be provided another way, for example a vented frame or an adjacent opener.
Do you cover all of County Antrim?
We arrange surveys and fitting across County Antrim.
Do I need permission for triple glazed fixed and picture windows in Northern Ireland?
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.
