Lanterns and rooflights are sized to the outside of the kerb, not the hole in the ceiling. The first numbers we need are the outside length and width of the kerb you are building, its height, and the roof fall. Timber or masonry, insulated, with the vapour control carried up it and the roof covering lapped over the top.
Glass never sits straight on the roof covering. Even a low-profile rooflight sits on a kerb, because the upstand is what keeps the water out. It is the detail that gets missed when a rooflight is ordered from a plan.
Electric vents, opening rooflights and blinds need a cable route before the roof is closed, so get the electrician on the plan early.


Five powder-coated colours for the quickest lead time. Any other RAL colour to order, to match the roof or the room.
Two-tone on request: a dark outside with a white inside is the usual ask. Confirmed on the quote.
Self-cleaning outer pane, argon filled, warm edge spacer and toughened safety glass as standard on every unit.
The standard unit. Glass U-value 1.2 W/m²K.
The upgrade for bigger lanterns and rooms that need to stay warmer. Glass U-value 0.7 W/m²K.
Cuts glare and heat on south-facing roofs. The figure is how much of the sun's heat the double glazed unit reflects.
What each product can take. Anything electric needs power to the kerb before the roof is finished.
