Aluminium has enjoyed a huge resurgence in recent years as more and more people discover that modern aluminium doors and windows can provide all the benefits that PVCu and timber windows can.
But by far, one of the biggest advantages of aluminium is how it is coloured. So here is what you should know about powder coated doors and windows.
What is powder coated aluminium?

Aluminium windows and doors benefit from powder coating technology that gives you huge colour choice and much more besides.
The way aluminium windows and doors are coloured is different from PVCu or timber. For example timber windows and doors are coloured using a wet paint process. PVCu windows are also coloured with a wet paint or the profiles can be covered with a foil instead of paint.
Powder coated aluminium uses a dry paint process using polyester powder. Before the aluminium extrusions are painted, they will undergo a series of cleaning and pretreatment processes so that any dirt and grime can be removed first. The aluminium profiles are submerged in a series of tanks that clean and prepare them for painting.
To paint the profile it is placed in the paint booth that is filled with the chosen colour powder. An electrical charge is applied to the extrusion and as the powder is sprayed it bonds onto the aluminium. The final part of the process once the aluminium has been painted is to bake it in a special oven as part of the curing process.
Virtually unlimited colour choice with aluminium.
Again one of the biggest advantages of powder coated finishes is the massive choice of colour available. You’ll have seen white, grey, black and brown windows in showrooms and you may even have had aluminium windows fitted yourselves previously.
However aluminium can give you a choice of over 200 colours. Add to this number further options of satin, matt or gloss finishes and your choice becomes bigger still.
Another advantage of modern aluminium profiles is that they make it very easy today to have different colours inside and out. This was previously much more difficult to achieve.
Powder coating doesn’t stop at basic colours.
Another advantage of powder coating and modern colouring processes is the contemporary range of colours available. If you’re looking for a highly contemporary finish you can choose metallic effect colours. These have the sparkle or sheen of bare metal and many architects are today favouring these types of colours.
We can also provide you textured paints. Our Sensations range of colours gives you all the above benefits of powder coated aluminium but the paint has a rough, textured and very tactile feel. This feels like sandstone, granite or limestone. It really does have to be seen to be appreciated.
Colour matching to existing windows.
Perhaps you had aluminium windows fitted a few years ago and are now looking to replace the rest of the windows in your home or add a new extension?
If you’re worried about colour matching on your window and doors, this is far easier to achieve than other materials. All we need is the original paint reference of your older windows and you’ll have a colour match assuming you’ve been cleaning your existing windows on a regular basis and they’re not faded or damaged.
Or you may be having one type of product from one supplier and your doors and windows from us and want to colour match? Again no problem the RAL reference will usually ensure that everything will look the same.
There are even ancillary items chosen for windows such as trickle vents, trims, architraves and add on sections that can all be powder coated to give your home a uniform appearance throughout.
So as you can see, powder coated windows and doors not only give you the slim lines, great aesthetics and strength that aluminium is renowned for but also a virtually unlimited choice of colour.
