Blackwood: powder coated aluminium windows
The price of aluminium windows depends on the size and number of frames, the profile system, opening sashes, colour and finish, glass specification and access. Dual colours, special finishes, glazing bars and triple glazing add cost. See the guide prices for typical ranges, and the written quote fixes your figure.
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.
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.
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

About Blackwood for this job
- Postcodes covered
- NP12 and the surrounding area, including Bargoed, Gelligaer and Abercarn
- Coast
- Blackwood sits roughly 19 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 Blackwood 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
- 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 Wales
- In Wales, Approved Document N covers safety glazing: safety glass is needed in and around doors and in low-level glazing where people could walk into it.

In Wales, replacing a whole window or glazed external door is building work and is notified either by an installer registered with a competent person scheme or through the local authority's building control. Replacing only the glass in an existing frame is treated as a repair.
Options to choose between
Flush casement
Sashes sit level with the outer frame for a clean, timber-like look, often chosen for period-style or contemporary homes.
Tilt and turn
Inward-opening sashes that tilt for secure ventilation or swing open for cleaning and escape, useful for flats and high floors.
Casement windows
Side-hung, top-hung or fixed sashes in slim aluminium frames, suiting most houses and extensions, with flush or stepped sash designs.
Aluminium Windows in Blackwood: questions
Are aluminium windows better than uPVC?
Neither is better for every home; they suit different priorities. Aluminium gives slimmer frames, larger glass areas, a hard-wearing powder-coated finish and a wide colour choice. uPVC usually costs less and has chunkier frames. Both can meet the energy standard for replacement windows when specified correctly, so compare the certified ratings, the look you want and the guide prices.
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.
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.
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.
