Intura FL Premium · Black Edition
Round flat roof window with glass: daylight with character
A round skylight adds something special to any room. With an Intura FL Premium round flat roof window, you can combine that striking shape with flat insulating glass and a stylish black finish. For daylight above the dining table, a view of the sky from the kitchen or an architectural feature in an extension.
Discover eight diameters ranging from Ø 60 to Ø 200 cm, with HR++ double glazing, HR+++ triple glazing or solar control glazing. Are you looking for a round dome for a flat roof? Then take a look at the alternative with flat glass, a matching flashing and a matt black aluminium frame in RAL 9005.
Black Edition: flat glass with a matt black edge.
Impression: natural light and a view of the sky.
Visual impression: a sleek accent on the flat roof.
A round roof window that adds both light and character
A round flat roof window breaks up the straight lines of a ceiling and naturally draws the eye. During the day, it brings natural light inside; from inside the room, you can look up at the sky through the clear glass. In this way, the light opening becomes part of the interior.
The round Intura FL Premium Flatlight is a fixed daylight solution for flat roofs. The flat glass and matt black aluminium frame give the window a sleek appearance. The Flatlight and the matching fibreglass flashing are finished in black RAL 9005 on the outside.
Use a single round skylight above a central point, such as a dining table or kitchen island. Or distribute several round skylights across a larger space. The appropriate diameter and positioning depend on the roof structure, the layout and the desired level of daylight.

Round dome or round flat roof window with glass?
Anyone looking for a round dome will come across various solutions. A traditional round dome usually has a domed cover made of acrylic or polycarbonate. A round flat roof window has a round light opening with flat glass.
The Intura FL Premium is a good choice if you want to combine the round shape with insulating glazing and a flat finish. You can choose between double or triple glazing, with clear or solar-control glass.
Intura round flat roof window with glass
- Top: flat insulating glass.
- Material: glass with a black aluminium frame.
- Insulation: double HR++ or triple HR+++.
- View: clear view through clear glass.
- Sun protection: choice of double or triple sun-protective glazing.
Round plastic dome
- Top: usually a spherical plastic dome.
- Material: acrylic or polycarbonate.
- Insulation: depends on wall thickness and any additional glazing.
- Appearance: depends on whether a clear or opal version is chosen.
- Sun protection: depends on the material and version.
Would you like a round skylight with a modern glass finish? Then a round Intura flat roof window is an attractive alternative to a plastic dome.
Compare the complete systems: glazing, frame, flashings and roof connection. The insulation value of the glazing alone does not indicate how the entire roof light performs.
From compact to spacious
Round flat roof windows in eight diameters
Choose a compact round skylight or a large glass surface that becomes a striking feature of the architecture. The range includes the following diameters:
Ø 60 cm
Ø 80 cm
Ø 90 cm
Ø 100 cm
Ø 120 cm
Ø 150 cm
Ø 180 cm
Ø 200 cm
A larger diameter provides a greater glass surface area. In the case of a circle, this surface area increases in proportion to the square of the diameter: a circular opening of Ø 200 cm has four times the surface area of an opening of Ø 100 cm. The actual amount of light entering also depends on the glazing, the orientation and the finish of the light well.
Please check the dimensions before ordering. The roof opening, clear light opening and external dimensions may differ from one another. The availability of each diameter and glazing option will be confirmed on request.
Daylight, insulation and summer comfort
Which glazing should you choose for your round roof window?
The right glazing depends on the use of the room, the desired insulation and the amount of sun on the roof. There are four glazing options:
HR++ clear double glazing
HR++ double glazing combines insulating glazing with a clear view. A suitable choice if you want to bring natural daylight and a view of the sky into a room beneath a flat roof.
Triple HR+++ clear glazing
Triple HR+++ glazing consists of three panes of glass and is designed to provide a higher level of insulation. It is an attractive option for projects where particular attention is paid to the insulation of the building envelope.
Double glazing HR++ solar control
This version combines double-glazed insulating glass with solar control properties. Consider A9 if the room receives a lot of direct sunlight and you wish to limit the amount of solar heat entering the room.
Triple glazing HR+++ with solar control
B9 combines triple glazing with solar control properties. This allows you to take both thermal insulation and solar gain into account when choosing your round flat roof window.
Solar control glass lets daylight in whilst limiting the amount of solar heat entering the room. The effect depends on the chosen glazing configuration. When making your choice, ask about the insulation value, light transmission and solar heat gain coefficient.
A round flat roof window for an extension, kitchen or living room
The positioning determines where the daylight falls and how you experience the round shape.
- Extension: bring light into the centre of the room, where façade windows have less reach.
- Kitchen: install a round skylight above the cooking island or work area.
- Living room: brighten up a seating area or the central part of the room.
- Dining room: give the dining table a distinctive spot beneath a round skylight.
- Hallway or landing: add daylight to a space with little natural light from the façade.
- Office or reception area: combine natural light with a striking design.
Adjust the position to suit the roof structure and the space below. A carefully finished round light well enhances the effect of the skylight.
Renovation and replacement
Replacing an existing round dome with glass
Do you want to replace a round plastic dome with a round flat roof window made of glass? Then have the existing situation assessed first.
As well as the diameter, the upstand, supporting structure, roof covering and available installation space are all key factors. The weight of the new unit and the connection to the roof insulation must also be taken into account.
Please send Intura photographs, dimensions and, if possible, a cross-section drawing. This will enable us to assess which model is suitable for your roof and what structural modifications are required.
