Winter light in Coleraine
Coleraine is far enough north that the December sun barely clears 11° at midday, with only about 7 h 08 min of daylight. Long, dark winters are where triple glazing’s lower heat loss matters most.
Rules 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.
- 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
Do you fit triple glazing in Coleraine?
Yes. We arrange surveys and fitting in Coleraine and the BT51 district. Send your postcode and what you need, and we will book a free survey.
Do I need planning permission in Coleraine?
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 before changing the style.
Which frame is best for a house in Coleraine?
It depends on the house rather than the town: uPVC for value, aluminium for slim frames and big panes, timber for period homes, alu-clad timber for low upkeep. Our surveyor will talk through the options.
How much does triple glazing cost in Coleraine?
Our guide prices are the same UK-wide: triple glazed uPVC windows from £695 each and a 3-bed semi from £9,395, fitted and inc VAT.
