VELUX FS C04 Fixed Skylight 550x980mm for Pitched Roofs

The VELUX FS C04 is a fixed skylight built for Australian tiled and corrugated roofing. At 550 x 980mm it is a mid-size fixed roof window that floods bedrooms, studies and smaller living spaces with natural daylight. Because the sash does not open, the frame stays slim and the glazed area is larger, which makes it an economical way to add sky views and light to a room.

Frequently Asked Questions

What size opening does the FS C04 need?

The FS C04 is a 550 x 980mm skylight, which matches the rough opening for a VELUX C04 unit. The correct flashing kit is selected to match both the skylight model and your roof material, so confirm the profile with the supplier before ordering.

Can I add blinds to a fixed skylight?

Yes. The fixed skylight is compatible with VELUX solar remote blinds, which are powered by the sun and controlled with a hand-held remote, so there is no wiring in the ceiling. That lets you filter light and reduce heat gain without touching the skylight.

Does a fixed skylight need a flashing kit?

Yes. A flashing kit is required to make the skylight weathertight against the roof, and it is sold separately. The right kit depends on the skylight model and whether your roof is tiled, corrugated metal, TrimDeck or Kliplok.

How much heat does the glazing block?

The double-glazed unit blocks approximately 75% of solar heat, which helps keep the room cooler in summer. The NEAT self-cleaning coating also helps rain wash dirt off the glass so the skylight stays clear with less maintenance.
