Most people choose aluminium window frame colours from a swatch card in a showroom, under lighting that looks nothing like a Perth summer afternoon. The colour is only half the decision. The finish sitting underneath it decides whether the frame still looks the same in fifteen years, and it is the part almost nobody asks about. If you are specifying aluminium window frames for a build or a renovation, that finish matters more than the shade.
Powder Coated Aluminium or Anodised: Two Very Different Finishes
Aluminium window frame colours sit on top of one of two finishes, and they are not interchangeable. Almost every residential frame in Western Australia is powder coated aluminium: a dry polymer powder is applied electrostatically to the bare extrusion and baked, so it fuses into a hard continuous skin. It is durable, and it comes in effectively any colour, which is what makes those huge swatch cards possible.
Anodising works differently. Rather than adding a layer on top, it grows a controlled oxide layer out of the aluminium itself, so the finish is part of the metal and cannot chip or peel. The trade off is range. Anodised aluminium colours are limited to natural silver, bronzes, blacks and a few champagne tones, because you are colouring an oxide layer rather than painting a surface.
Both have their own Australian Standards. Architectural powder coating is specified under AS 3715, revised in 2025, and anodic coatings under AS 1231. Those standards set coating thickness, adhesion and weathering performance, so a specification naming one is worth more than a supplier simply calling a finish durable.
Do Aluminium Window Colours Fade in the Perth Sun?
Some do, and coating grade is the biggest factor. Powder coatings are made in different durability grades, from standard architectural polyesters through to super durable and fluoropolymer grades built for high ultraviolet exposure. Perth sits under some of the highest UV levels of any Australian capital, so a grade that holds colour in Hobart is not automatically the right call here.
Pigment choice matters too. Deep reds, bright blues and many organic pigments are less stable under UV than the oxides used in greys, whites and blacks, so the aluminium window colours that fade first are usually the boldest ones. Ask for the coating grade in writing, because a colour name on a quote tells you nothing about how it will weather.
Why Black Aluminium Windows Behave Differently to White
Black aluminium windows are the most requested look in Perth right now. There is nothing wrong with them, but they behave differently. A dark frame absorbs far more solar radiation, so surface temperatures on a north or west facing wall climb well above what white aluminium windows reach beside them.
- More thermal movement. Aluminium expands as it heats, and on long spans that movement has to be allowed for in how the frame is made and fixed.
- More heat transferred inwards. A hot frame conducts warmth into the room, which is why dark frames pair well with double glazing or a thermally broken frame.
- Higher coating demand. Dark colours run hotter, so the coating works harder, and a super durable grade earns its place.
- Visible surface marking. Matte black shows dust, salt film and fingerprints more readily than mid greys, so it wants washing more often.
None of that is a reason to avoid black. It is a reason to specify the coating and the glazing to match the colour rather than treating the colour as a purely visual choice.
Choosing Window Frame Colours That Suit the House
The most reliable approach is to pick aluminium window frame colours against the fixed elements of the building rather than the trend of the moment. Roof, brick, render and gutter colours are staying put for decades, so they are the honest reference points.
- Monument window frames against light render or pale brick, for contrast without the heat load of a true black.
- Surfmist windows on coastal and Hamptons style homes, where a warm off white stays softer than a stark white.
- Anodised natural or bronze on mid century and brick homes, where a metallic finish reads as period appropriate.
- Frames matched to the screens. A frame and a screen in slightly different blacks is very obvious once installed, so specify security screen doors and frames together.
We are also asked constantly whether existing frames can just be repainted. Site painting over a factory finish does not bond the way a baked coating does, and it will generally void the coating warranty. The proper routes are stripping and recoating the extrusion off site, or replacing the frames, depending on the condition of the existing sections.
Why Choose Action Glass & Aluminium for Aluminium Window Frames in Perth
Salt is the other half of the Perth story. Homes within a few kilometres of the coast sit in a marine environment, and airborne salt left on a coating accelerates its breakdown, particularly around fixings and cut edges. Coating warranties are typically conditional on regular fresh water washing, and in coastal zones that condition is stricter.
Because we manufacture rather than resell, we can talk through coating grade, exposure and colour together instead of handing you a swatch card. We have worked on Perth homes, shopfronts, schools and industrial buildings since 1969, our glass installation meets AS 1288, and our workmanship is guaranteed. Our custom aluminium windows and doors are built to suit the opening and the exposure.
