RAL Classic Colour Chart for Timber Windows & Doors

Understanding the RAL Classic Colour Chart System

The RAL Classic Colour Chart has been the benchmark for standardized colour communication across architecture, manufacturing, and building design since its creation in 1927 by the German Institute for Quality Assurance and Certification. Officially managed by RAL gGmbH, each tone is designated by a unique 4-digit code that ensures exact colour uniformity regardless of the batch or manufacturer.

When selecting exterior coatings for timber sash windows, box casements, and solid wood doors, referring to a certified RAL colour chart eliminates the risk of tone discrepancies between separate building components. At Timber Sash Store, all our hardwood frames are spray-finished in factory-controlled conditions using microporous breathable paints from Teknos Coatings, tinted to any hue within the complete RAL Classic Colour Chart catalogue.

Popular Colour Groups: From Natural Tones to Statement Finishes

Navigating the full collection of hues all RAL Classic palettes offer allows homeowners and specifiers to strike the right balance between traditional period elegance and contemporary design. Below are the primary shade families featured in our chart:

1. Architectural Whites, Creams & Blacks (9000 Series)

The collection of white and black hues represents the most frequently specified palette for UK conservation areas and Victorian townhouses. Shades like RAL 9016 Traffic White and RAL 9010 Pure White deliver a crisp, clean appearance on box sash windows, while RAL 9005 Jet Black and RAL 9004 Signal Black provide bold, modern contrast on contemporary heritage conversions.

2. Heritage Greys & Modern Neutrals (7000 Series)

Grey tones continue to dominate architectural trends across London and the UK. RAL 7016 Anthracite Grey, RAL 7035 Light Grey, and RAL 7040 Window Grey blend seamlessly with both London brickwork and smooth render facades.

3. Warm Earth Tones, Yellows & Oranges (1000 & 2000 Series)

For country cottages, rustic residences, and bespoke timber entrances, the classic yellow hues orange nuances provide welcoming warmth. Tones such as RAL 1013 Oyster White, RAL 1015 Light Ivory, and rich ochres replicate historic period pigments while offering maximum UV stability.

4. Classic British Greens & Coastal Blues (6000 & 5000 Series)

From RAL 6005 Moss Green to RAL 5011 Steel Blue, deep botanical and maritime shades pay homage to Georgian and Edwardian heritage palettes approved under Historic England Guidelines for Traditional Windows.

Expert Tips for Choosing Shades from the RAL Classic Colour Chart

Selecting the right tone from the RAL Classic Colour Chart for your property involves balancing architectural authenticity, surrounding masonry colours, and interior daylight levels. Here are recommendations from our joinery specialists:

• Dual Colour Options: Timber windows can be finished in dual tones. You can select an external shade from the RAL Classic Colour Chart (such as RAL 7016 Anthracite Grey or RAL 6005 Moss Green) to complement your exterior facade, paired with RAL 9016 Traffic White inside to maximize light reflection in interior rooms.
• Matte vs. Gloss Finishes: All colours from the ral colour chart can be applied with varying sheen levels. A 30% semi-matte finish is our standard for exterior timber sash windows as it masks minor wood grain variations while retaining high durability.
• Conservation Planning Compliance: If your home is listed or located in a Conservation Area, always consult with your local planning authority. Many UK councils favor muted shades such as RAL 9001 Cream or RAL 1013 Oyster White over ultra-bright whites.

Frequently Asked Questions About the RAL Classic Colour Chart

Can any timber sash window be painted in any RAL colour?

How long does a factory-sprayed RAL coating last on timber?

Under normal UK weather conditions, our multi-coat factory finish provides 8 to 10 years of weather protection before recoating is required, significantly outperforming on-site brush application.
