Slim aluminium windows in Eastleigh
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.
Upper-floor windows may need to work as escape routes. In England, Approved Document B guidance for an escape window is an unobstructed openable area of at least 0.33 m², at least 450mm high and 450mm wide, and no more than 1100mm from floor to the bottom of the opening.
Modern aluminium window frames contain a thermal break: strips of low-conductivity material, usually polyamide, that separate the inner and outer aluminium. Without it, heat passes straight through the metal. Older aluminium windows made without thermal breaks are a common cause of cold frames and streaming condensation.
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.

- Coast
- Eastleigh sits roughly 8 km from the nearest coastline, close enough that exposure on open or high ground is worth considering. 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 Eastleigh the midwinter sun reaches about 16° above the horizon at noon, with roughly 7.7 hours of daylight, rising to about 62° and 16.3 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 England
- Approved Document K requires safety glass in critical locations in England: glazing in doors and in side panels within 300 mm of a door, up to 1500 mm above floor level, and any glazing in walls or partitions up to 800 mm above floor level.

Listed buildings in England need listed building consent for most changes to historic windows or glass, and conservation areas can restrict changes visible from the street. Speak to the council's conservation officer before ordering.
Choosing your aluminium windows
Flush casement
Sashes sit level with the outer frame for a clean, timber-like look, often chosen for period-style or contemporary homes.
Dual-colour powder coat
A different colour inside and out, such as anthracite grey outside with white inside, from a wide range of RAL colours and textures.
Steel-look windows
Very slim frames with glazing bars that mimic traditional metal windows, adding thermal performance and double glazing to the classic look.
Aluminium Windows in Eastleigh: questions
How much do aluminium windows cost?
The cost of aluminium windows depends on the number and size of windows, the profile system, how many sashes open, the colour and finish, the glass and the access. They generally cost more than equivalent uPVC because of the material and factory coating. See the guide prices for typical ranges; the written quote fixes the price for your exact specification.
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.
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.
Do I need permission to replace windows with aluminium?
In England, replacing windows on a house with ones of similar appearance usually does not need planning permission, but changing the material or style can matter. Flats and maisonettes lack permitted development rights for windows, and listed buildings, conservation areas and Article 4 directions can require consent. Building regulations apply to replacement windows across the UK, with different detail in each nation.
