Anthracite grey sliding doors across Northumberland
Before you settle on a door type, it helps to know what anthracite grey sliding doors do well and what to check before you order.
If your Northumberland home is listed, is a flat, or is covered by an Article 4 direction, check with the council before changing the colour of a door that faces the street.
If the windows on your Northumberland home are already anthracite, take a photo of the colour label on a frame or the paperwork so the door can be specified to the same RAL number.
- A blue-grey tone frames the garden view without the hard contrast of black, so the door reads as part of the elevation rather than a dark outline.
- Because the colour is part of the frame, not a film over it, small marks on aluminium can usually be touched in with a matched repair kit rather than replacing the section.
- Dual colour lets you keep anthracite on the outside for kerb appeal while choosing white or a soft neutral inside, so the frame suits the room you see every day.

Daylight and glass in Northumberland
Sun angles matter for big glazed doors. Around Northumberland, 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.

Approvals in England
In England, a replacement sliding door is a controlled fitting under the Building Regulations. In an existing home, a door with more than 60% glazing must reach a U-value of 1.4 W/m²K or better (or a Doorset Energy Rating of band C) under Approved Document L, and glass in doors must be safety glazing under Approved Document K. We arrange compliance through a competent person scheme installer or by notifying Building Control, and you receive the certificate.
Questions about anthracite grey sliding doors in Northumberland
Is the price different in Northumberland?
No. Guide prices for anthracite grey sliding doors are the same across mainland Britain, including Northumberland. The fitted price depends on size, system, glass and finish, and any structural work, all fixed in your written quote after survey.
What colour is RAL 7016?
RAL 7016 is anthracite grey, a dark grey with a slight blue undertone. It is one of the most widely specified colours for aluminium and uPVC windows and doors in the UK. On a sliding door it looks lighter in bright daylight and closer to charcoal on an overcast day, so it is worth seeing a physical sample outdoors before deciding.
Can I have anthracite outside and white inside?
Yes, a dual colour frame lets you have anthracite grey outside and white or another colour inside. Thermally broken aluminium frames have separate inner and outer sections joined by an insulating bar, so each side can be powder coated in its own colour before the frame is assembled. Dual colour adds a modest percentage to the price, which your quote shows.
What is the difference between textured and smooth anthracite?
Textured anthracite has a fine grain you can feel, while smooth anthracite has a flat satin or matt surface. Textured finishes hide fingerprints, light scratches and water marks better and suit doors that get heavy use. Smooth finishes look sleeker and more minimal but show dust and marks more readily. Both are durable powder coatings applied the same way.
