Size tip: A larger skylight does not automatically mean a better result. Roof structure, room proportions, orientation and the internal shaft can all affect how daylight spreads. For help, send Central Skylights your room and roof photos before ordering.
Why Choose a VELUX FCM Fixed Flat Roof Skylight?
The VELUX FCM is a fixed, non-opening glass skylight designed for flat and low-pitch roof applications. It is a strong choice when the main goal is to bring natural daylight into a room without adding ventilation or electric opening components.
- High-performance double glazing
- Laminated inner safety glass
- Toughened outer glass
- Clean, low-profile roof appearance
- Suitable for many flat and low-pitch applications
- Available in 14 different sizes
- Ideal for replacing many old dome-style skylights
- Works well with a properly designed plaster shaft
More Daylight, No Ventilation Required
FCM is best suited to rooms where natural light is the priority. For kitchens, hallways, living rooms, bedrooms, bathrooms and internal spaces, a fixed skylight can be a simple and effective way to brighten the room.
A Modern Alternative to Acrylic Domes
Many older skylights use acrylic or polycarbonate domes that can age, discolour or look dated. A glass FCM can provide a cleaner, more contemporary appearance where the existing opening and roof construction are suitable.
Flat Roof Installation, Upstands & Custom Flashing
A VELUX FCM installation is not only about choosing the skylight size. The roof profile, roof pitch, waterproofing method, upstand or kerb, flashing design, roof opening, structural framing and internal shaft all need to work together.
Custom Flashing
Flat and low-pitch roof projects commonly require a flashing solution matched to the roof material, roof profile and installation method. Central Skylights can help with suitable custom flashing solutions for many Melbourne projects.
Complete Installation
For suitable projects, our installation service can include the roof opening, skylight installation, custom flashing, shaft framing, plastering and sanding, ready for painting.
Builders, roofers, renovators and owner-builders can also purchase the skylight on a supply-only basis. For custom flashing information, visit our custom flashing for flat roofs section.
Important: The correct installation method depends on the actual roof. Before ordering a skylight or flashing, confirm the roof material, roof pitch, opening size and proposed installation detail.
FCM vs Manual & Solar-Opening Flat Roof Skylights
VELUX FCM — Fixed
Choose FCM when your main goal is natural daylight and you do not need the skylight to open. It is the simplest option in the flat-roof VELUX range.
VELUX VCM — Manual Opening
Consider a manual-opening model when you want daylight plus the ability to ventilate the room without electric or solar operation.
VELUX VCS — Solar Opening
A solar-opening model can suit rooms where ventilation and remote operation are important, particularly when the skylight is positioned out of easy reach.
Which One Should You Choose?
Start with the room. If ventilation is unnecessary, FCM is usually the logical fixed option. If airflow matters, compare the opening VELUX skylight ranges.

VELUX FCM Frequently Asked Questions
Does a VELUX FCM skylight open?

How many VELUX FCM sizes are available?

Can an FCM replace an old acrylic dome skylight?
In many projects, an FCM can be considered as an upgrade from an older dome-style skylight. Suitability depends on the existing opening, roof structure, dimensions and the new flashing or upstand detail.
Do I need custom flashing for a flat roof installation?
Many flat and low-pitch installations require a custom flashing solution matched to the roof material, profile, pitch and installation detail. Confirm the roof conditions before ordering.
