Flat rooflights for Slough homes
A single near-flat pane on an upstand: minimal, low and discreet.
In midsummer the noon sun stands about 61.9° high over Slough, so roof glazing gets the full strength of it. That is why solar-control glass is worth considering on larger lanterns here.
- Fixed or electric opening versions
- Usually cheaper than a lantern
- Minimal, frameless-looking from inside

In England, building regulations energy guidance sets a limiting U-value of 2.2 W/m²K for new and replacement rooflights in existing homes, measured horizontally.
Lanterns on permitted development extensions are part of the extension's height limits. Adding one to an existing roof is different: over 150 mm of projection can mean a planning application.
Building regulations in Slough 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.
