Powerdaylight Ø 53 cm Eco Cradle flat roof exterior (roof) components
Additional or enhanced items in this Eco upgrade
- High-performance insulated glass daylight collector
- Insulation lens
- 30 cm multifoil insulation
Key Features:
- Better insulation performance, thermal transmittance of the assembled system is U=0.76 W/m²K* (passive house standards)
-
Replacing the traditional polycarbonate dome with a flat glass plate greatly enhances the visual appeal – offering a modern, refined look that integrates seamlessly with contemporary architecture
-
Recyclable and eco-friendly: Glass is fully recyclable and has a lower environmental impact in the long run.
Performance Guidelines:
- Light spread (diameter at floor level): approx. 5 metres depending on ceiling height.
- Recommended maximum system length: 15 metres

*Not included but necessary to achieve specification - multi-layer foil insulation (External tube insulation jacket to BS EN12667 & ISO8302 (0.0345 W/m²K))
Powerdaylight Round ECO Cradle System - flat roof flashing
The Powerdaylight Cradle is a light tube that is suitable for a flat or slightly sloping roof. The Powerdaylight 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.
