Black roof lanterns for Isleworth homes
RAL 9005 jet black for crisp contrast and steel-look interiors.
In midsummer the noon sun stands about 62.0° high over Isleworth, so roof glazing gets the full strength of it. That is why solar-control glass is worth considering on larger lanterns here.
- Usually no surcharge as a stock colour
- Pairs with steel-look screens and doors
- Sharp contrast against sky and ceiling

Planning and building regulations for Isleworth
For homes in England, a new or replacement rooflight should achieve a U-value of 2.2 W/m²K or better in the horizontal position, under Approved Document L.
Planning-wise, a lantern on a new extension is judged as part of that extension, while one added to an existing roof can fall outside permitted development if it stands more than 150 mm proud.
Building regulations in Isleworth 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.
