Aluminium windows in Larne
Aluminium frames are usually finished with polyester powder coating, baked on at the factory in a choice of RAL colours and in matt, satin or textured finishes. Dual-colour frames are possible, such as anthracite grey outside and white inside, so the windows can suit both the street and the room.
Steel-look aluminium windows reproduce the slim frames and glazing bars of traditional metal windows while adding a thermal break and double glazing. They are often chosen to replace failing original steel windows in 1930s houses, though conservation areas and listed buildings may need consent for the change.
Aluminium is strong enough to hold large, heavy glass units in narrow frames, so sightlines are slimmer than uPVC of the same size. That means more glass and more daylight from the same opening, which suits modern extensions, wide picture windows and slim replacements for old steel windows.
Powder-coated aluminium does not need painting, but it does need cleaning. Wash frames with warm water and a mild detergent a few times a year, rinse, and avoid abrasive pads or solvents. Clean more often near the sea or busy roads, where salt and grime sit on the surface for longer.
Included as standard

About Larne for this job
- Postcodes covered
- BT40 and the surrounding area, including Carrickfergus, Ballyclare and Newtownabbey
- Coast
- Larne is about 1 km from the coast or a tidal estuary, so salt air and wind-driven rain are worth planning for. Salt air attacks metal finishes, so aluminium windows near the coast need a coating and pretreatment suited to marine exposure, stainless or protected hardware, and more frequent washing. Check that the coating terms allow for a coastal site before ordering.
- Daylight and sun
- In Larne the midwinter sun reaches about 12° above the horizon at noon, with roughly 6.9 hours of daylight, rising to about 59° and 17.1 hours in midsummer. Slim aluminium frames let more daylight through the same opening. Large south or west-facing panes can overheat rooms, so solar-control glass may help, while north-facing rooms benefit from high light-transmission low-E glass that keeps heat in during short winter days.
- Access and setting
- Rural homes often mix old stone walls with modern extensions, and aluminium suits both when profiles are chosen carefully. Irregular openings are measured individually, and exposed sites benefit from systems with high weather ratings and well-sealed joints against driving rain.
- Rules in Northern Ireland
- Technical Booklet V covers safety glazing in Northern Ireland, including glass in and around doors and low-level glazing where people could walk into it.

Aluminium Windows in Larne: questions
Do aluminium windows get condensation on the frames?
Modern thermally broken aluminium windows are far less prone to frame condensation than older aluminium windows made without a thermal break. Condensation can still form on any window if a room is humid and poorly ventilated, so trickle vents, extractor fans and sensible heating still matter. Warm-edge spacer bars also help keep the edges of the glass warmer.
How long does it take to install aluminium windows?
Most single windows are fitted within a day, and a typical house takes a few days on site depending on the number of windows and the access. The longer part is manufacturing, because frames are cut, coated and glazed to the survey sizes. The expected lead time is confirmed in writing when you accept the quote.
Can aluminium windows replace original steel windows?
Yes, steel-look aluminium windows are designed for this. They copy the slim frames and glazing bars of old metal windows while adding double glazing and a thermal break. Original steel frames are often set into the masonry, so removal can disturb render or plaster, and the survey checks this. Listed buildings and conservation areas may need consent first.
What guarantee do aluminium windows come with?
Manufacturer guarantees apply to the frames, powder coating, hardware and sealed units, and the terms are confirmed in writing. Coating cover often depends on the site environment and on regular cleaning, so read the conditions. Guarantee terms for the installation are set out in writing with your quote, before you agree to go ahead.
