Anthracite grey sliding doors across Cornwall
Here is what to weigh up if you are considering anthracite grey sliding doors for a home in Cornwall:
If your Cornwall 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.
Choosing a colour for a Cornwall extension that will be seen from the garden all day? Hold textured and smooth anthracite samples up in daylight before committing to either.
- 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.
- 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.
- Anthracite frames pair well with dark grey handles, interlocks and track covers, giving a coordinated finish where no bright metal parts catch the eye.

Daylight and glass in Cornwall
In Cornwall the shortest day has roughly 8 h 01 min of daylight and the longest about 16 h 26 min. The noon sun sits near 16° above the horizon in winter and 63° in summer — so glass that faces south collects useful warmth from October to March, while a west-facing door may need solar control to stop it overheating in July.

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 Cornwall
Is the price different in Cornwall?
No. Guide prices for anthracite grey sliding doors are the same across mainland Britain, including Cornwall. The fitted price depends on size, system, glass and finish, and any structural work, all fixed in your written quote after survey.
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.
How does powder coating work?
Powder coating is a dry finishing process that bonds coloured polyester powder to the aluminium with heat. The profiles are cleaned and pretreated, the powder is sprayed on with an electrostatic charge so it clings evenly, and the frame is baked until the powder melts into a smooth, hard film. It resists chipping and fading far better than wet paint.
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.
