Black sliding doors across County Londonderry
A few practical points decide whether black sliding doors suit a particular room and opening:
Have white render on your County Londonderry property? Black frames give the sharpest contrast against it, but view jet black and signal black samples on the wall before choosing.
Where the rest of a County Londonderry home has white windows, a black sliding door on the rear extension can work well, provided the extension reads as a separate, modern addition.
- Powder coating bonds the black colour to the metal with heat, so the frame does not need repainting, only washing with mild soapy water a few times a year.
- Jet black RAL 9005 gives a crisp, deep contrast against white render or pale brick, turning the door into a strong graphic element on the elevation.
- Signal black RAL 9004 is a fraction softer than jet black, which can suit homes with warmer stone or brick where a pure black would look harsh.

Questions about black sliding doors in County Londonderry

The door price is the same as anywhere else. Because County Londonderry is covered by arrangement, any travel cost for delivery and fitting is shown in your quote before you order; the survey itself is free.
Can I have black sliding doors in uPVC?
Yes, uPVC sliding doors can be supplied in black, usually as a foil laminated to the white uPVC profile. Dark foils on uPVC expand more in strong sun than aluminium, and the look and texture differ from powder-coated aluminium. Our uPVC sliding doors page explains the colours available on that material.
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.
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.
