Duplus Octagonal Roof Lanterns

Our Octagonal roof lantern is low pitch and frameless adopting the same technology as our most popular lantern rooflights and pyramid rooflights which means it has no internal hip framework. This ensures that the maximum amount of natural light is able to penetrate through to the room beneath.

Not only does this give a more contemporary appearance, but structural silicone glazing techniques offer greatly improved thermal efficiency when compared to similar products that rely on supporting internal aluminium framework.

Advanced Features

Duplus octagonal glass roof lanterns are double glazed in clear HEATSOAKED toughened safety glass as standard.

We offer a range of tints:

  • Blue tint
  • Bronze tint
  • Grey tint

Why not opt for an obscure finish for privacy or high performance solar control to minimise solar gain (g) and maximise light transmittance (Lt).

This octagonal rooflight is also available without external cappings for a truly frameless external appearance.


Material Specifications & U-Value

Our rooflights achieve outstanding thermal performance. True U-value and Ud-value available upon request.

The extruded thermally broken aluminium perimeter frame is powder-coated RAL 7016 dark grey matt externally and RAL 9910 white matt internally as standard. External hip cappings are fitted for aesthetics and are powder coated RAL 7016 dark grey matt to match the external perimeter frame at the base of the pyramid rooflight. Other RAL colour options are available upon request.

As standard, all our Octagonal rooflight double glazed units incorporate HEATSOAKED clear low ‘E’ glass achieving a centre pane U-value of 1.1 W/m²K. Please refer to our FAQ section for an explanation of heatsoaked glass.

Delivered FULLY ASSEMBLED. No need for time-consuming assembly on site. Furthermore, significantly higher security compared to kit systems.
