How big a roof lantern or flat roof light can go, the roof pitch it sits at, and the glazing and colour choices — across our Korniche and Infinity ranges.
We supply two glazed roof ranges — Korniche and Infinity — each offering both a pitched lantern roof and a flush flat roof light. Here's what each can actually do, size- and spec-wise, based on the manufacturers' own published figures.

| Minimum size | 850mm × 850mm (square), 850mm × 732mm (rectangular) |
| Maximum size | Up to 6m × 4m (rectangular), up to 4m × 4m (square/pyramid, 4 glass units) |
| Roof pitch | Fixed 25° |
| Glazing | 28mm double-glazed units, argon-filled, warm-edge spacer bar; self-cleaning glass available |
| Security | PAS24 as standard |
| Standard colours | Gloss White (RAL 9910), Matt Grey (RAL 7016), Matt Black (RAL 9005) — bespoke RAL/BS and dual-colour also available |
| Warranty | 10 years |

Figures as published by Infinity. Exact minimum/maximum order sizes for your chosen style — ask the trade counter for the full made-to-measure range before specifying.
Both ranges offer two distinct glazed roof styles:
If you'd rather replace an existing conservatory roof entirely with a solid, fully insulated tiled roof instead of more glazing, see our SupaLite tiled roofs page.
Korniche's roof lantern goes up to 6m × 4m (external) for a rectangular lantern, or 4m × 4m for a square or pyramid lantern made from 4 glass units. Infinity's aluminium roof lanterns are also available made-to-measure — check with our trade counter for the exact size range on your preferred style.
Korniche's minimum order size is 850mm × 850mm for a square lantern, or 850mm × 732mm for a rectangular one.
Korniche's lantern roof uses a fixed 25° pitch. A flat roof light (Infinity Roof Light or Korniche Flat-Glass) sits flush and isn't pitched in the same way — it's designed for flat-roof openings instead.
A roof lantern has a pitched, multi-panel glazed roof that sits up from the ceiling line, giving extra height and a more traditional conservatory-roof look. A flat roof light sits flush with a flat roof for a minimal, frameless-looking result. We supply both as separate systems within the Infinity and Korniche ranges.
