Flat rooflights for Corsham homes
A single near-flat pane on an upstand: minimal, low and discreet.
In midsummer the noon sun stands about 62.0° high over Corsham, so roof glazing gets the full strength of it. That is why solar-control glass is worth considering on larger lanterns here.
- Sized to your upstand
