Product details
Performance per combination (Glass + skylight)
Each additional wall added to the skylight improves the thermal insulation (U-value). The finish (Clear, Opal, Heatstop) determines how much light and solar heat enters.
(Explanation of terms: U-value = Insulation value (the lower, the better) | LT = Light transmission | G = Solar gain/heat transmission)
iDome + Single-walled skylight
The most popular base for maximum light incidence.
- Insulation value (U-value): 0,93 W/m²K
- Clear (Acrylic/PC): LT: 66-68% | G: 44-46%
- Opal (Acrylic/PC): LT: 44-62% | G: 32-40%
- Heatstop (PC): LT: 37% | G: 31%
iDome + Double-walled skylight
The perfect balance between extra insulation and high light yield.
- Insulation value (U-value): 0,79 W/m²K
- Clear (Acrylic/PC): LT: 58-61% | G: 37-40%
- Opal (Acrylic/PC): LT: 38-55% | G: 27-33%
- Heatstop (PC): LT: 31-33% | G: 24-27%
iDome + Triple-walled skylight
High-performance thermal insulation for living spaces.
- Insulation value (U-value): 0,69 W/m²K
- Clear (Acrylic/PC): LT: 53-55% | G: 33-34%
- Opal (Acrylic/PC): LT: 46-47% | G: 25-27%
- Heatstop (PC): LT: 28-30% | G: 21-23%
iDome + Four-walled skylight
Extreme insulation for passive or nearly zero-energy construction (BENG).
- Insulation value (U-value): 0,61 W/m²K
- Clear (Acrylic/PC): LT: 48% | G: 28-29%
- Opal (Acrylic/PC): LT: 44% | G: 24-25%
- Heatstop (PC): LT: 24-26% | G: 17-20%
iDome + Five-walled skylight
The absolute best in energy saving.
- Insulation value (U-value): 0,55 W/m²K
- Clear (Acrylic/PC): LT: 44% | G: 25%
- Opal (Acrylic/PC): LT: 40% | G: 22%
iDome + EP10 skylight
Maximum thermal performance with diffused light.
- Insulation value (U-value): 0,60 W/m²K
- Opal (Acrylic/PC): LT: 38% | G: 22-23%
Rw value (Acoustic value in dB)
For anyone bothered by tapping rain or ambient noise, sound insulation is essential. The Skylux iDome series clearly leads the way in noise reduction.
- Rw value iDome: 40 dB (Constant across all plastic top skylights)
- Performance: This makes the iDome almost 2x quieter than a standard 3-walled plastic skylight. Say goodbye to irritating tapping during a rain shower.
Glass & Construction
- Glass composition: Layered inner pane and tempered outer pane.
- Super-insulating PVC frame: The compact frame is filled with EPS (Ue value 0,49 W/m²K) for maximum insulation without cold bridges.
- Self-cleaning effect: Because the flat glass is covered by a domed plastic skylight, dirt rinses away easily and water does not remain on the surface.
- Burglar-resistant & Safe: Sleekly finished, fitted with anti-burglary screws/clips and 100% impact-resistant.
