Are anthracite grey sliding doors right for homes in Hertfordshire?
These are the points a surveyor will go through with you when you choose anthracite grey sliding doors for a home in Hertfordshire:
Choosing a colour for a Hertfordshire extension that will be seen from the garden all day? Hold textured and smooth anthracite samples up in daylight before committing to either.
If your Hertfordshire home is close to the sea, washing powder-coated frames more often removes salt deposits and helps the anthracite finish keep its sheen.
- Powder coating is cured in an oven into a continuous film, giving a hard-wearing finish that does not need repainting, only occasional washing with mild soapy water.
- Grey sits comfortably with a wide range of materials, from buff and red brick to white render, timber cladding and stone, which keeps future redecorating options open.
- RAL 7016 is a widely used reference colour for windows and doors, which makes it easier to tie new sliding doors in with existing frames, fascias and garage doors.

Daylight and glass in Hertfordshire
At the latitude of Hertfordshire, the midday sun climbs to about 62° in late June but only about 15° in late December, when daylight lasts around 7 h 46 min against 16 h 42 min in midsummer. A south-facing anthracite grey sliding door lets that low winter sun deep into the room; on a west or south elevation, solar-control glass keeps summer afternoons comfortable.

Approvals in England
English Building Regulations treat a new or replacement external door in an existing home as a controlled fitting: it needs a U-value of 1.4 W/m²K or better (or Doorset Energy Rating band C) if more than 60% of it is glazed (Approved Document L), and safety glass in a critical location (Approved Document K). Compliance is arranged through a competent person scheme installer or a Building Control notification, so you get a certificate for your records.

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.
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.
Will anthracite aluminium match my anthracite uPVC windows?
It should be close, but it may not be identical. uPVC windows usually get their colour from a laminated foil, while aluminium is powder coated, so the texture and sheen can differ even when both are RAL 7016. Lighting also affects how each looks. Bringing a sample from the door to the window is the most reliable check.
