Powerdaylight Ø 35 cm Round Cradle ECO System - flat roof flashing
Powerdaylight 35cm Round Cradle ECO System - flat roof flashing
The Powerdaylight Cradle ECO is a light tube that is suitable for a flat or slightly sloping roof. The Deplosun daylight tube captures the daylight through a flat glass panel and transports it inside using a highly reflective tube.
The ECO version of the Powerdaylight Cradle is an extra insulated variant of the standard Cradle system. The flat glass panel is fitted with low-emission glass, the air chamber of which is filled with argon gas. The system achieves an insulation value of 0.74W/m²K, making this version suitable for passive construction.
The Powerdaylight daylight system is equipped with the following as standard:
- A flat glass panel made of toughened glass, which gives it impact and scratch resistance.
- A ‘Powerdaylight Cell’ reflective grid integrated within the flat glass panel which captures daylight and reflects it down into reflective tube.
- Reflective aluminum tubing which has an internal silver surface treatment with a specular reflection of up to 98%.
The Powerdaylight brand is aware of the potential of reusing materials and makes a conscious choice not to use plastic. Powerdaylight systems are manufactured from materials such as glass and aluminium which are 100% recyclable and sustainable.
