Are black sliding doors right for homes in Edinburgh and the Lothians?
The right door depends on the opening, the room and the way you use the garden. Here is how black sliding doors tend to work out in practice:
Want black frames on your Edinburgh and the Lothians home but worried about upkeep? The textured sandtex finish is a sensible middle ground, since it hides marks far better than smooth black.
Got a small, north-facing back room in Edinburgh and the Lothians? A dual colour frame keeps the black outside while a paler inner face stops the room feeling boxed in.
- Black frames can be paired with black handles, interlock caps and track covers so the whole door, including its hardware, reads as a single dark outline.
- Thermally broken aluminium systems are designed to cope with the extra expansion that comes from dark frames heating up in strong sun.
- A black frame recedes against the view, so even a door with a standard-width interlock can look slimmer and more minimal than the same profile in a pale colour.

Daylight and glass in Edinburgh and the Lothians
Sun angles matter for big glazed doors. Around Edinburgh and the Lothians, midday sun reaches about 58° in summer and drops to about 11° in winter. That low winter sun is free heat through south-facing glass; high summer sun is easier to shade with a roof overhang, and solar-control glass helps where there is none.

Questions about black sliding doors in Edinburgh and the Lothians
Is the price different in Edinburgh and the Lothians?
No. Guide prices for black sliding doors are the same across mainland Britain, including Edinburgh and the Lothians. The fitted price depends on size, system, glass and finish, and any structural work, all fixed in your written quote after survey.
Do black sliding doors get hot in the sun?
Yes, black frames absorb more solar heat than lighter colours, so on a south- or west-facing elevation they can become hot to touch on a sunny afternoon. Good thermally broken aluminium systems are designed to handle the extra expansion. If the glass area is large, solar-control glass helps limit how much heat passes into the room as well.
What is the difference between RAL 9005 and RAL 9004?
RAL 9005 is jet black, the deepest standard black, while RAL 9004 is signal black, which is very slightly lighter and softer. Side by side, 9005 looks more intense and 9004 can appear marginally warmer. On a door frame the difference is subtle, so most people decide by looking at both samples against their own brick or render.
Does a black frame affect the U-value?
The frame colour does not meaningfully change the tested U-value of an aluminium sliding door, which depends on the thermal break, the glass and the seals. A good double glazed thermally broken aluminium slider typically achieves around 1.2–1.6 W/m²K for the whole door, depending on the system and glass specification.
