Anthracite grey roof lanterns for Windsor homes
RAL 7016 anthracite grey, a widely chosen colour to match grey doors and windows.
In midsummer the noon sun stands about 62.0° high over Windsor, so roof glazing gets the full strength of it. That is why solar-control glass is worth considering on larger lanterns here.
- Matt or textured finishes
- Usually no surcharge as a stock colour
- White inside to keep ceilings bright

Planning and building regulations for Windsor
England's Approved Document L caps the U-value of new or replacement rooflights in existing homes at 2.2 W/m²K, calculated with the glass horizontal.
On a permitted development extension the lantern counts towards the extension's height; on an existing roof, a rooflight projecting more than 150 mm may need planning permission.
Building regulations in Windsor are checked by your local authority building control team or a registered building control approver. Replacing a rooflight in an existing home is building work. Installers registered with a competent person scheme can self-certify; otherwise building control must be involved.

Questions from Windsor
Can the inside be a different grey?
Yes. Any combination is possible on most aluminium ranges; non-stock colours carry a small surcharge.
Will anthracite get hot in the sun?
Dark frames absorb more heat than white, but lantern frames are designed for it. The bigger effect on room temperature is the glass, which is why solar-control glass matters on south-facing roofs.
Can you fit a roof lantern in Windsor?
We can quote for fitting where we have cover. Send your postcode and photos of the roof and kerb, and we will confirm before quoting.
Who checks building regulations for a lantern in Windsor?
Your local authority building control team or a registered building control approver. For a lantern in a new extension it forms part of the extension's approval; replacements in existing homes have their own rules.
