Square roof lanterns for Belfast homes
Four triangular panes meeting at a point: a pyramid lantern for square openings.
On the shortest day Belfast gets about 7h 15m of daylight, with the sun only 12.0° above the horizon at noon. Light from the sky overhead is the brightest available in winter, which is exactly what a roof lantern collects.
- No ridge, a neat apex cap instead
- Strong central focal point from below
- Ideal over a table, island or hallway

Questions from Belfast
Is a pyramid lantern more expensive than a rectangular one?
Per square metre it can cost slightly more, because every pane is a triangle and the apex needs a special joint. The difference is usually small next to the effect of size and glass choice.
Can I have an opening vent in a pyramid lantern?
Some ranges can fit a vent in one of the triangular panes, others cannot. We will tell you on the quote whether your chosen range allows it.
Is it worth having solar-control glass in Belfast?
With the midsummer sun about 58.8° high at noon, roof glass in Belfast gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
How quickly can I get a roof lantern in Belfast?
Stock sizes are typically ready in 5–10 working days, made-to-measure in 3–4 weeks, plus delivery. Your quote gives the date for BT1.
