    The skylights arrived promptly and looked fantastic. I attached flanges and installed it as a flush mount on my roof eave. It provides additional light at the door while still shielding against rain—a truly ideal solution.

Product details

VELUX FCM 3446 Flat Roof Skylight 970 x 1275mm

The VELUX FCM 3446 is a premium large rectangular fixed flat roof skylight for Melbourne homes that need a stronger daylight feature without moving into the very largest FCM sizes. Its 970 x 1275mm frame and 876 x 1181mm visible glass area make it ideal for kitchens, dining areas, living rooms, stairwells, extensions and open-plan spaces.

Key product details

Daylight area Approximately 1.03m² visible glass area, before any internal shaft or lining effect.
Approx. weight 29.48kg product/shipping weight, excluding custom flashing. Confirm final handling requirements 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 3446.

Best rooms Kitchens, dining rooms, living areas, stairwells, larger bathrooms, open-plan extensions, studios and brighter hallway zones.

Best suited for

The FCM 3446 works well when you want a generous daylight feature with a balanced rectangular shape. It gives noticeably more light than smaller square models, while still being easier to position than the longest flat roof skylights.

This makes it a strong choice above kitchen benches, dining zones, stairwells, family rooms and modern extensions where natural light needs to feel broad, premium and intentional.

Fixed or opening?

Related opening models to compare

The FCM 3446 is the fixed daylight-only option. If the room also needs fresh air, odour release or passive ventilation, compare nearby opening flat-roof skylight models before ordering.

Current model

FCM 3446 Fixed

Best for maximum natural light with a clean, low-maintenance fixed glass design. Ideal where ventilation is not required.

Best for: daylight, sky view, lower maintenance and a premium fixed-glass finish.

Nearby opening option

VCM 3434 Manual Opening

A nearby manual-opening flat-roof model for rooms where fresh air is useful and the skylight can be operated by hand or pole.

Best for: bathrooms, laundries, kitchens and rooms needing simple ventilation.

Nearby solar option

VCS 3434 Solar Opening

A nearby solar-powered opening flat-roof model with remote operation, useful where easy control and automatic rain protection are priorities.

Best for: higher ceilings, convenience, ventilation and smarter operation.

Note: FCM 3446 is fixed-only. If you need opening ventilation in a similar flat-roof format, confirm the closest available VCM or VCS size before ordering.

Model guide

About this VELUX FCM model

About the VELUX FCM 3446

The VELUX FCM 3446 flat roof skylight is a fixed glass skylight designed for generous daylight, modern glazing performance and a clean low-profile roof appearance. Its 970 x 1275mm format gives broad, useful light coverage for medium to large interiors.

Compared with older acrylic or polycarbonate domes, the FCM 3446 offers a premium glass finish that will not yellow, crack, craze or become brittle in the same way over time.

Fixed vs opening options

The FCM 3446 is a fixed, non-opening skylight. It is best when the goal is natural daylight, sky view and a clean ceiling feature rather than ventilation.

If airflow is important, compare nearby opening flat-roof models such as the VCM 3434 manual opening skylight or VCS 3434 solar opening skylight. For daylight only, the FCM 3446 keeps the system simpler and lower maintenance.

Supply only vs installed

Central Skylights can supply the FCM 3446 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

Large flat roof skylights need careful planning around roof fall, kerb height, roof profile, sheet layout and flashing design. The 970 x 1275mm size should be positioned so daylight spread, external waterproofing and internal shaft design 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.
