Powerdaylight Ø 25 cm pitched roof exterior (roof) components

Transform your home or workplace into a bright, healthy environment with Powerdaylight’s innovative daylight systems. Our unique light-capturing dome draws in an abundance of natural light from all angles, channelled through a reflective tube. The stylish ceiling diffuser then disperses the soft, natural light throughout the room.

Small but mighty – for the smallest spaces at home or work

The Ø 25 cm version offers the best insulation values in its class. It’s ideal for illuminating compact areas such as toilets, small bathrooms, or hallways – and especially suited for use in listed or heritage buildings.

The Powerdaylight Ø 25 cm efficiently transports daylight to smaller spaces in both residential and commercial settings. Think of hallways, corridors, attics, toilets, or even walk-in wardrobes. This system is suitable for all roof types in both housing and utility buildings. We recommend using it for ceiling heights up to 3 metres.
