Mildenhall: steel look aluminium windows
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 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.
Large aluminium windows that reach low down, such as floor-to-ceiling glazing, need safety glass. In England, Approved Document K treats glazing within 800mm of the floor as a critical location, so those panes are usually toughened or laminated and permanently marked to show their safety classification.
Aluminium windows are fabricated to order: profiles are cut, coated, assembled and glazed to the survey sizes. Lead times can be longer than for standard white uPVC, particularly for special colours or steel-look designs, and the expected timescale is confirmed in writing when you accept the quote.

Mildenhall at a glance
- Postcodes covered
- IP28 and the surrounding area, including Newmarket, Bury St Edmunds and Ely
- Coast
- Mildenhall is well inland, around 52 km from the nearest coast, so salt exposure is not usually a factor.
- Daylight and sun
- In Mildenhall the midwinter sun reaches about 14° above the horizon at noon, with roughly 7.4 hours of daylight, rising to about 61° and 16.6 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 Mildenhall: questions
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.
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.
What colours can aluminium windows be?
Aluminium windows can be powder coated in almost any RAL colour, in matt, satin, gloss or textured finishes, and many systems offer a different colour on each side. Anthracite grey, black and white are common choices, but heritage greens, creams and bronze tones are available too. Special colours can extend the manufacturing lead time, which is confirmed with the quote.
