Aluminium Window & Door Colours & RAL Options

Every aluminium window, door and bifold we supply on the Smart Alitherm and Visofold/Visoglide systems is polyester powder-coated to order — a durable, weather-resistant finish that goes well beyond the handful of colours shown on most brochures. Here's what's actually available.

Finish types available

Smart Systems offers standard and non-standard finishes including full RAL colour matching, metallic finishes, anodised effect finishes, textured finishes, and dual colour (a different shade inside and out) on the Alitherm range as a standard option.

Smart's colour ranges

Smart groups its standard finishes into five named colour families, plus full custom RAL on request:

The five ranges

Naturals — everyday shades built around whites, greys and anthracite; the range most installations are specified in.
Sensations — Smart's textured colour range.
Cotswold — stone and countryside-inspired shades.
Alchemy — metallic finishes.
Creations — bold statement colours: Ruby Red, Sapphire Blue, Mint Green, Pastel Blue, Zinc Yellow and Moss Green.

Common examples

Traffic WhiteRAL 9016

Jet BlackRAL 9005

Anthracite GreyRAL 7016

Anthracite Grey (RAL 7016) is widely regarded as the most popular exterior colour for aluminium windows and doors in the UK.

These are examples, not the full chart. Ask the trade counter for the complete Smart Systems swatch and RAL chart before specifying, especially for non-standard or bespoke colours — lead times differ from the standard ranges above.

Choosing a colour for your project

Matching an existing UPVC or roofline colour on the same property — bring a sample or the original spec to the trade counter.
Dual colour is worth considering if your internal decor scheme differs from your preferred exterior — it's a standard option, not a bespoke upcharge, on the Alitherm range.
Textured and metallic finishes (Sensations, Alchemy) read differently in direct sunlight than a flat gloss or matt — ask to see a sample panel rather than judging from a screen.

Frequently asked questions

Can I have a different colour inside and outside?

Yes — dual colour is a standard option on Smart's Alitherm 400 and Alitherm Heritage aluminium systems, so you can match an internal decor colour while choosing a bolder shade outside.

Can you match a specific RAL code that isn't shown here?

Yes, non-standard RAL and bespoke colours are available in addition to the standard Naturals, Sensations, Cotswold, Alchemy and Creations ranges — ask us for a price and lead time, as bespoke finishes are ordered specially.

Does colour affect price or lead time?

Standard range colours are the fastest and most cost-effective option. Non-standard RAL or bespoke finishes are ordered specially and can extend the lead time — see our lead times guide.
