Like-for-like replacement for most post-war homes. A casement window has sashes hinged at the side or top that open outwards, the most common window style in UK homes.

Winter light and glass choice in Ballymena

By midsummer Ballymena has about 17 h 20 min of daylight, but in December only around 7 h 11 min, with the noon sun at about 12°. Triple glazing keeps more heat in during those long, dark months; big south and west windows may suit solar-control glass for summer.

Rules for casement 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

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.

  • No pressure: the quote is yours to keep

Questions from Ballymena

Do casement windows need trickle vents?

If the old windows had them, yes, and at least as large. If not, ventilation must be no worse than before. We size this on survey.

Are triple glazed casements harder to open?

They are a little heavier, but with correctly sized hinges they open and close smoothly.

Do you fit triple glazed casement windows in Ballymena?

Yes. We arrange surveys and fitting in Ballymena and across County Antrim. Send your postcode and the windows or doors you want replaced, and we will book a free survey.

Do I need permission for triple glazed casement windows in Ballymena?

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.
