A roof lantern gives more light from several sides and adds height and shape to a flat roof, while a skylight sits low, costs less and is simpler to fit. Choose a lantern for a statement feature in a larger room and a skylight for a smaller space or where height is limited.
How do a lantern and a skylight compare?
| Feature | Roof lantern | Skylight |
|---|---|---|
| Light | From several angles | Mainly from directly above |
| Appearance | Raised, architectural | Flush and discreet |
| Heat loss | More glass area, so greater loss | Smaller glazed area |
| Fitting | Needs an upstand and bigger opening | Simpler to fit |
| Cost | Higher | Lower |
Do the same regulations apply?
Mostly. A new or replacement rooflight, including a lantern, must reach 2.2 W/m²K or better under Approved Document L. A roof window in a pitched roof of 15 degrees or more has a tighter limit of 1.6 W/m²K.
When is a skylight the better choice?
A skylight is the better choice for small rooms, tight budgets and exposed locations where a raised structure adds wind load or planning difficulty. The room size and roof height are the deciding factors.
