Where a lantern adds height and presence, a flat rooflight disappears: a single sealed pane sitting almost flush on its kerb, reading from inside as a clean rectangle of sky.

We supply fixed flat rooflights in standard and bespoke sizes — double or triple glazed, walk-on rated where needed — supply-only UK-wide or installed by our teams.
Modern flat rooflights are structurally bonded units: the glass adheres to a slim aluminium sub-frame, leaving no visible fixings and almost no frame sightline from below. A 3–5 degree fall, built into the kerb or the unit, keeps rainwater shedding. Standard double glazing covers most rooms; triple glazing answers bedrooms and Passivhaus-leaning specs; and walk-on rated units with laminated structural glass turn flat roofs and terraces into usable floors above habitable rooms. Sizes run from compact 600 × 600 hallway lights to bespoke panes over 3m, with solar-control and self-clean coatings throughout the range.

Lanterns add height, presence and all-direction light — right for big kitchen-diners. Flat rooflights are quieter: flush, minimal, perfect for hallways, bathrooms, smaller rooms and strict modern aesthetics. Many projects use both.
A small one — 3 to 5 degrees of fall so water sheds rather than ponds. It's built into the kerb or the unit itself and is invisible from inside the room.
A structurally rated unit with thick laminated glass engineered for foot traffic — it turns a flat roof or terrace into usable floor while lighting the room below. Each one is load-calculated for its span.
Yes — electric opening versions with rain sensors are available for ventilation and, in the right configuration, for roof-access duty. Fixed units remain the slimmest and most economical.
Standard ranges run past 3 metres on the long edge, and bespoke structural units go larger. Beyond certain spans glass thickness steps up — we'll spec it for the size and walk-on requirements.
