Square roof lanterns for Falmouth homes
Four triangular panes meeting at a point: a pyramid lantern for square openings.
In midsummer the noon sun stands about 63.3° high over Falmouth, so roof glazing gets the full strength of it. That is why solar-control glass is worth considering on larger lanterns here.
- Stock colours or any RAL on request
- No ridge, a neat apex cap instead
- Strong central focal point from below

Planning and building regulations for Falmouth
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.
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 Falmouth 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.
