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 35 cm is the most versatile daylight tube, a real all-rounder. The Solatube Ø 35 cm has double the daylight output of the Solatube Ø 25 cm and therefore transports daylight to every room in a home or business premises. For example, in homes – rooms such as the living room, bedroom, bathroom and in commercial buildings - meeting rooms, offices, corridors and retail spaces. This Solatube can be used on all types of roofs. We would suggest a maximum ceiling height of up to 3 metres for the Solatube Ø 35 cm system.

Round and square
The Solatube Ø 35 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 35 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.

The Cradle version is available for the Solatube Ø 35 cm round and is provided with the Cradle to Cradle (C2C) certificate. This certificate guarantees that the production process has no impact on the environment.

At Techcomlight we are aware of the potential of reusing materials. It is therefore a conscious choice not to use plastic in the Cradle version. The materials used, such as glass, are 100% recyclable and sustainable.

Walkable and driveable
The unique feature of the Powerdaylight daylight system is that the system is optionally available in both walk-over and drive-over versions. Ideal for illuminating areas under (roof) terraces, gardens and sidewalks.

The drive-over dome has even more load capacity than the walk-over variant (400 kg), namely 1000 kg. This makes it possible for vehicles such as motorcycles and cars to drive over this flat dome.

Two adjustable angles
Unless you are installing into a flat roof, you will almost certainly require adjustable angle adaptors; every Solatube Ø 35 cm daylighting system is supplied with two 0-30 degree adjustable angles as standard.

The Solatube Ø 35 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 Solatube Ø 35 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 Solatube Ø 35 cm through a vertical wall or the façade of a building.

Unusual applications
In addition to the standard applications, the Solatube Ø 35 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 Solatube 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.
