Compare the finish in context, not from a screen alone
Use the swatches to establish a direction, then confirm the exact supplier reference, texture and sheen on a physical sample. Availability varies by frame, panel and manufacturer.
Strong architectural contrast for aluminium, uPVC and composite systems.
| Material | Common finish route | Useful strengths | Confirm before ordering |
|---|---|---|---|
| Aluminium | Powder coating, smooth or textured | Broad RAL choice, durable dark colours, dual colour | Supplier range, sheen, marine-grade needs and lead time |
| Timber | Opaque paint or translucent stain | Warm, repairable finish with traditional detail | Maintenance cycle, grain variation and coating system |
| uPVC | Coloured substrate or applied foil | Low maintenance, woodgrain effects, dual colour on selected systems | Exact foil, frame compatibility and external/internal face |
| Composite doors | Factory-finished slab and frame | Coordinated panel, glazing and furniture options | Panel/frame colour match, hardware finish and batch variation |
Can the inside and outside be different colours?
Many aluminium and selected uPVC systems offer dual-colour frames. The exact combination depends on the product, coating or foil range and lead time, so both faces should be written into the quotation.
Is the same RAL colour identical across every product?
Not always. Substrate, texture, sheen, batch and coating method affect how a colour appears. Compare adjacent components on approved physical samples rather than relying on the RAL reference alone.
Which dark colour is easiest to live with?
Dark finishes can show dust, salts and surface marks more readily. A textured or satin finish is often more forgiving than a high gloss, but maintenance and exposure should be discussed for the actual property.
