With the innovative daylight systems from Powerdaylight you can transform your home or workplace into a healthy and pleasant place to live or work. The unique light-harvesting dome brings in a huge amount of daylight through a reflective tube from every angle. The diffused natural light is spread into the room by means of a stylish ceiling diffuser.

The Solatube Ø 25 cm transports daylight into smaller areas of a home or business premises, such as a hallway, attic, toilet or perhaps a walk-in wardrobe. This Solatube can be used in both residential and commercial construction and on all types of roofs. We would suggest a maximum ceiling height of up to 3 metres for the Solatube Ø 25 cm system.

Round and square
The Solatube Ø 25 cm system is available with various ceiling diffuser style options in both a round or square finish. The square diffuser system also has a unique option which can be recessed into the ceiling.

The Solatube Ø 25 cm system can be upgraded to the ECO (Energy Care Optima) specification which enhances the thermal and acoustic properties making it suitable for Passive construction.

Two adjustable angles
Unless you are installing into a flat roof, you will almost certainly require adjustable angle adaptors; every Solatube Ø 25 cm daylighting system is supplied with two 0-30 degree adjustable angles as standard.

The Powerdaylight Ø 25 cm can be used on all types of roofs and facades. The flat roof flashing is suitable for all types of roof coverings such as EPDM, PVC, TPO, Bitumen, CPE.

The Powerdaylight Ø 25 cm pitched roof flashing comprises of Ubiflex, a non-lead waterproof flashing material manufactured from reinforced aluminium mesh with a mixture of modified bitumen, which makes installation quick and easy.

In addition to flashings for corrugated iron, profiled steel or thatched roofs there is also an option available to install a Powerdaylight Ø 25 cm through a vertical wall or the façade of a building. 

Unusual applications 
In addition to the standard applications, the Solatube Ø 25 cm can also be used in a number of specific and unusual applications, such as lighting fauna and bicycle tunnels, installed underground to light a cellar or basement or installed through a prefabricated chimney. If your potential application is not listed, please do not hesitate to contact us.

As the sun does not always shine (or, on the contrary, if there is a need for less daylight), it is possible to integrate various optional accessories into this Powerdaylight system, such as an artificial (electrical) light fitting, a daylight dimmer and even a bathroom ventilation system. If required, security and fire protection options are also available.
