What is a flat skylight?

A flat skylight is a low glazed unit set into a flat roof, so daylight falls straight into the room below. It lights deep plans, hallways, landings and extensions that side windows cannot reach.

01

Fixed skylights

The simplest build, which does not open and suits hallways, landings and rooms with other ventilation.

02

Openable skylights

Opens to let warm air rise out and fresh air in, for hot kitchens and extensions with no opening window.

03Technical specification

04Asked before every survey

The questions that matter.

What is the difference between a fixed and an openable skylight?
A fixed skylight only lets light in, while an openable one also ventilates. Choose openable for a kitchen, an extension or any room that gets hot in summer with no other opening window, and fixed for a hallway or landing where air already moves.
Do I need planning permission for a flat skylight?
Often not for a house, but it turns on how far the unit projects and on the property. Flats, conservation areas and listed buildings are stricter, and Building Regulations apply on top. Your architect or your council gives the answer for your address.
Will a flat skylight leak?
Not when it is fitted properly. The weak point on a skylight is rarely the glass. It is the junction between the unit, its kerb and the roof covering. We measure on site before manufacture, and the same team supplies and fits the unit.
