Slim aluminium windows across Croydon
Security on aluminium windows comes from multi-point locking, internally glazed beads, lockable handles and robust hinges. For easily accessible windows in new homes in England, Approved Document Q expects security to the PAS 24 standard, and specifying the same for ground-floor replacements is a sensible precaution.
Aluminium windows can be fitted with trickle vents in the frame head, which matters because in England, Approved Document F expects ventilation after window replacement to be no worse than before. The glazier records the existing vents at survey and sizes new ones to suit each room.
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.
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.

Working in Croydon
- Postcodes covered
- CR0, CR2, CR5, CR7, CR8, CR9, SE19, SE25 and the surrounding area, including South Croydon, Wallington and Carshalton
- Coast
- Croydon is well inland, around 33 km from the nearest coast, so salt exposure is not usually a factor.
- Daylight and sun
- In Croydon the midwinter sun reaches about 15° above the horizon at noon, with roughly 7.6 hours of daylight, rising to about 62° and 16.4 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
- Large aluminium units are heavy, so city jobs need planned unloading, parking and sometimes lifting gear or extra hands for upper floors. Flats need freeholder consent and planning permission, and conservation areas often control frame colour and glazing bar patterns.
- 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.

Approved Document B covers escape windows. Where an existing window is an escape route, typically in first-floor bedrooms, its replacement should give at least the same escape opening as before.

Aluminium Windows in Croydon: questions
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.
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.
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.
How do I look after powder-coated aluminium windows?
Clean powder-coated aluminium windows with warm water and a mild, non-abrasive detergent a few times a year, then rinse and dry. Avoid scouring pads, solvents and pressure washers close to the seals. Keep drainage slots clear and put a little light oil on hinges and locking points. Near the coast, more frequent washing removes salt deposits.
