Duplus Circular Rooflights

Our fixed circular rooflights are structurally silicone glazed to give a sleek, elegant appearance with exceptional strength and rigidity. Our product is delivered fully assembled and is very easy to install. The framework of our circular rooflight is manufactured from an extruded aluminium profile that is curved using our in-house rolling machinery. This enables us to produce a wide range of circular rooflight sizes to meet your specific requirements.

Water & Dirt Runoff

The flush glaze design of our circular rooflights allow water and dirt to run off the edge with ease. Ideally we would recommend installing these rooflights and any ‘flat’ rooflights with a slight fall to enable this process.

Optional Finishes

Duplus circular rooflights are double glazed in clear HEATSOAKED toughened safety glass as standard.

Options are available:

  • Blue tinted glass
  • Bronze tinted glass
  • Grey tinted glass
  • Obscure finish for privacy
  • High-performance solar control (minimise solar gain (g) and maximise light transmittance (Lt))




Yes, we offer circular walk-on rooflights. Our standard circular rooflights are not walk-on. Please contact Duplus for a quotation.

Material Specifications, Installation & U-Value

Our circular rooflight achieves outstanding thermal performance. True U-value and Ud-value are available upon request.

The extruded aluminium perimeter frame is powder-coated RAL 9005 black matt as standard. Other RAL colour options are available upon request.

As standard, all double glazed units incorporate clear low ‘E’ glass achieving a centre pane U-value of 1.1 W/m²K.

Very easy to install and available in sizes from 1000mm diameter to 2000mm diameter without the requirement for intermediate bars.

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