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.
