Powerdaylight Ø 35 cm ECO flat roof exterior (roof) components
Additional or enhanced items in this Eco upgrade
- Insulated flat roof flashing
- Insulation lens
Key Features:
- Better insulation performance, thermal transmittance of the assembled system is U=0.7 W/m²K* (passive house standards) as opposed to 1.3 W/m²K of the standard
- Superior sound insulation, 66 dB as opposed to 62 dB of the standard
Performance Guidelines:
- Max. ceiling height: 5 metres
- Light spread (diameter at floor level): approx. 4 metres depending on ceiling height.
- Recommended maximum system length: 9 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 Ø 35 cm ECO flat roof exterior (roof) components
Versatile and a true all-rounder. Has double the light output of the Powerdaylight Ø 25 cm and can therefore be placed in any room of the house or used to illuminate areas within commercial premises such as meeting rooms, corridors and showrooms.
Flat roof flashing
The flat roof flashing is suitable for all types of flat roof coverings, such as: EPDM, PVC, TPO, Bitumen, CPE.
At an additional cost, the flashing is available with a PVC coating to ensure good adhesion with PVC roof coverings. The flat roof flashing is also available with an increased upstand height for green roof applications.
ECO
ECO is an optional enhancement available for the Powerdaylight 25 cm and 35 cm models (Pitched and flat roof) to enhance the thermal and acoustic properties of the Powerdaylight daylighting system to passive house standards
Supplied with
- Inner dome = Additional dome provides double glazed element at roof level
- Insulated roof flashing = Twin-skinned, insulated flashing, available for flat or pitched roof
- Insulation lens = Creates thermal compartments within the tube
Product features
- Double daylight output compared to Ø 25 cm ECO
- Brightens workplaces as well as houses
- Thermal transmittance of the assembled system U=0.7 W/m²K* (passive house standards)
*Not included but necessary to achieve specifications multi-layer foil insulation (External tube insulation jacket to BS EN12667 & ISO8302 (0.0345 W/m²K))
