Circular Rooflight

Starting from £1199

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 rooflight sizes to meet your specific requirements.


Duplus fixed rooflights are double glazed in clear toughened safety glass as standard, with options of blue, bronze or grey tinting or if preferred, an obscure finish for privacy or high performance solar control to minimise solar gain (g) and maximise light transmittance (Lt).


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