Steel look aluminium windows in Christchurch: what to know
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.
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.
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.
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.
What a typical job includes
- Fitting, sealing and finishing the reveals neatly
- Thermally broken aluminium frames powder coated to order
- Removal and disposal of the existing windows
- Sealed double or triple glazed units to specification

- Coast
- Christchurch 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 Christchurch the midwinter sun reaches about 16° above the horizon at noon, with roughly 7.7 hours of daylight, rising to about 63° 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.

Aluminium Windows in Christchurch: 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.
Are aluminium windows secure?
Aluminium windows can be very secure, because the metal is strong and the frames carry multi-point locks, internal glazing beads and lockable handles. For easily accessible windows in new homes in England, Approved Document Q expects PAS 24 security. Asking for windows tested to that standard is a good benchmark when replacing ground-floor windows in an existing home.
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.
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.
