Its 550 x 1800mm frame and 462 x 1711mm internal glass size make it ideal for open-plan living areas, kitchens, dining spaces, long hallways, stairwells and feature shafts where maximum daylight is the priority and ventilation is not required.

Best suited for

The FS C12 is best used when you want a tall architectural daylight feature while keeping the narrow 550mm VELUX C-size width. It can visually stretch a room, brighten a long hallway or bring a dramatic sky view into a stairwell or open-plan space.

Because of its extra-tall format and 38.55kg weight, this model needs more planning around lifting, rafter location, flashing, shaft design and roof access than smaller FS skylights.

Light & heat control

Suitable blind for VELUX FS C12

Because the FS C12 has a large vertical glass area, a matching VELUX solar remote blind is especially useful for controlling glare, heat and privacy in bedrooms, living areas, west-facing rooms, TV spaces and home offices.

VELUX Solar Remote Blinds for FS Skylights

The matching blind product for FS C12 is the VELUX FS blind range, including FSCD Solar Honeycomb Blackout and FSLD Solar Translucent options. Select the FS C12 550 x 1800mm size option when ordering.

  • FSCD Solar Honeycomb Blackout: best for stronger room darkening, glare control and heat reduction.
  • FSLD Solar Translucent: best for softer filtered daylight while still reducing glare.
  • Solar remote operation: convenient control without needing a hard-wired power connection.

When should you add a blind?

A blind is worth considering when the skylight is above a bedroom, living area, home office, TV area or any room where you want better control over sunlight, privacy and summer heat.

For most FS C12 installs, the skylight, flashing and blind should be selected together so the size and accessories match correctly before ordering.

Need ventilation?

Nearby opening pitched roof skylight options

The FS C12 is a fixed daylight-only skylight. If the room also needs airflow, compare nearby 550mm-wide opening models before ordering. These are smaller than FS C12 but add natural ventilation.

Manual opening

VELUX VS C08 Manual Opening Skylight

A manual-opening pitched roof skylight for natural light and fresh air. It includes an insect screen and can be operated by winder handle or rod, depending on reach.

Electric opening

VELUX VSE C08 Electric Opening Skylight

A wired electric-opening skylight with remote operation, built-in rain sensor and insect screen. A premium option when the skylight is out of reach but power is available.

Solar opening

VELUX VSS C08 Solar Opening Skylight

A solar-powered opening skylight with wireless operation, rain sensor and insect screen. A convenient ventilation option without needing a hard-wired power connection.

Model guide

About this VELUX FS model

About the VELUX FS C12

The VELUX FS C12 fixed skylight is designed for pitched roof homes where the priority is maximum daylight, a stronger sky view and a clean interior finish rather than ventilation.

Its white painted interior frame, grey aluminium exterior cappings and low-profile roof position make it a premium daylight upgrade for larger rooms, older skylight replacements, long ceiling shafts and spaces that feel too dark during the day.

Fixed vs opening options

The FS C12 is a fixed, non-opening skylight. It is usually the simplest VELUX option when you want a large daylight feature without an opening mechanism.

If ventilation is required, compare nearby 550mm-wide opening models such as the VS C08 manual opening skylight, VSE C08 electric opening skylight or VSS C08 solar opening skylight.

Supply only vs installed

Central Skylights can supply the FS C12 for pickup from Noble Park, arrange Melbourne delivery where available, or help with a complete supply-and-install option for suitable projects.

Supply-only is useful for builders, roofers and renovators who already have trades arranged. Homeowners often prefer full installation for a larger unit like this, especially where the job needs roof preparation, flashing, shaft framing, plastering and lifting coordination.

Melbourne installation notes

Pitched roof skylight installation depends on roof pitch, tile or metal roof profile, rafter spacing, water flow and the correct flashing selection. FS C12 has an extra-tall frame, so final placement should balance daylight spread, roof framing, lifting access and the finished internal shaft.

Before ordering, confirm whether your roof is tiled, corrugated, TrimDeck, Kliplok or another metal profile so the correct C12 flashing can be matched to the skylight.
