Triple glazed fixed and picture windows in Belfast
Looking at triple glazed fixed and picture windows for a home in Belfast? We survey, quote and fit across County Antrim, and the BT1 postcode district is part of that.
The best energy performance of any window type: no opening gaps. A fixed or picture window does not open; it is one large pane in a slim frame, used to frame a view or bring in light.
Winter light and glass choice in Belfast
In Belfast, midday sun in late December sits around 12° high, with roughly 7 h 15 min of daylight. For windows facing north or shaded by neighbours, cutting heat loss matters more than solar gain; on open south-facing glass, ask about a higher solar-gain unit.

Rules for fixed and picture 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.
Planning: 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
The surveyor measures every opening, checks ventilation, escape windows and safety-glass zones, and talks through styles. Your written quote lists each item with its glass build-up and U-value, and the price is fixed for that specification.

Questions from Belfast
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.
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.
