    Gideon Robert –

    I appreciate the quality of the product, its simple operation for opening and adjusting the shade, and how well it withstands different weather conditions. I’ve suggested it to anyone seeking to bring more natural light into their home, and our contractor found the installation process very straightforward.

    Cuthbert A –

    The delivery was delayed by 5 days; however, the skylights arrived on the same day the roofers came, and the work was almost complete. So, they unloaded the goods and immediately put them on the roof for installation.

Product details

VELUX FCM 3046 Flat Roof Skylight 870 x 1275mm

The VELUX FCM 3046 is a premium medium-large fixed flat roof skylight designed for brighter, more open interiors. Its 870 x 1275mm frame and 775 x 1181mm visible glass area make it a strong option for kitchens, dining rooms, living areas, raked ceilings, extensions and larger hallway zones where a square skylight may not provide enough daylight coverage.

Key product details

Product size 870 x 1275mm
Internal glass size 775 x 1181mm visible glass size.
Daylight area Approximately 0.92m² visible glass area, before any internal shaft or lining effect.
Approx. weight 27.67kg excluding flashing. Plan safe handling, lifting and roof access before installation.
Suitable roof type Flat and low-pitch roof applications where a suitable kerb/upstand and custom flashing detail can be used.
Roof pitch Suitable for roof pitches from 0° to 60°, subject to correct installation and waterproofing. A slight pitch is recommended where possible to reduce water ponding.
Flashing required Requires custom-made flashing, sold separately. See the matching custom flashing for VELUX FCM 3046.
Related opening models Need ventilation as well as daylight? Compare the VELUX VCM 3046 manual opening skylight or the VELUX VCS 3046 solar opening skylight.
Best rooms Kitchens, dining areas, living rooms, raked ceilings, open-plan rooms, extensions, larger hallways and stairwells.

Best suited for

The FCM 3046 is ideal when you want a noticeable daylight feature without choosing an extra-large skylight. Its rectangular shape gives a stronger spread of light than a small square model, making it well suited to kitchen benches, dining tables, lounge zones and longer ceiling areas.

It is also a good choice for many Melbourne renovation projects where the goal is to replace an older acrylic dome with a cleaner, glass, low-profile VELUX finish.

Model guide

About this VELUX FCM model

About the VELUX FCM 3046

The VELUX FCM 3046 flat roof skylight is a fixed glass skylight made for large, clear daylight without mechanical operation. It is a polished option for Melbourne homes where the room needs more light than a compact skylight can offer, but where ventilation is not required.

Compared with older acrylic or polycarbonate domes, the FCM 3046 provides a modern glass finish, high-performance glazing and a smooth low-profile exterior that helps suit contemporary rooflines.

Fixed vs opening options

The FCM 3046 is a fixed, non-opening skylight. It is best when the goal is daylight, sky view and a clean ceiling feature rather than airflow.

If the room needs ventilation, compare this model with the VELUX VCM 3046 manual opening skylight or the VELUX VCS 3046 solar opening skylight. For daylight only, the FCM 3046 keeps the system simpler and more cost-effective.

Supply only vs installed

Central Skylights can supply the FCM 3046 for pickup from Noble Park, arrange Melbourne delivery where available, or help with a complete supply-and-install option for suitable projects.

Supply-only suits builders, roofers and renovators who already have trades arranged. Homeowners often prefer full installation where the job needs roof preparation, custom flashing, shaft framing, plastering and finishing coordination.

Melbourne installation notes

Flat roof skylight installation in Melbourne needs careful planning around roof fall, kerb height, roof profile, sheet layout and flashing design. The 870 x 1275mm size should be positioned so the daylight spread, roof waterproofing and internal shaft all work together.

Before ordering, confirm whether the roof is corrugated, TrimDeck, Kliplok, tiled, membrane or another roof system so the correct custom flashing can be matched to the site.

Related opening models

Want the same size with ventilation?

Choose the fixed FCM 3046 when you only need natural light. If the room also needs airflow, the matching VCM and VCS 3046 opening models give you the same 870 x 1275mm size family with added ventilation options.

VELUX VCM 3046 Manual Opening Skylight

A cost-effective opening flat roof skylight with manual operation and a removable insect screen. Best suited when the skylight is within reach or can be operated with a rod.

VELUX VCS 3046 Solar Opening Skylight

A solar-powered opening flat roof skylight with remote operation, rain sensor and insect screen. Best suited for hard-to-reach areas or premium ventilation control.

How heavy is the FCM 3046?

Which rooms suit this size?

Can this replace an old acrylic dome skylight?

It can suit some replacement projects, especially where the existing opening and kerb are compatible, but the roof opening, throat size, kerb size and roof condition must be checked first.

Can Central Skylights install it?

Central Skylights can help with supply-only, pickup, delivery or full Melbourne installation depending on your roof type, access, location and project requirements.
