All of our products come with the following features

Our contemporary styled fixed octagonal rooflight incorporate structural silicone glazing techniques ensuring a complete, factory finished, high quality product. Fully watertight with a high quality, flush glazed and elegant appearance. Our fixed rooflights incorporate fully enclosed double glazed units to eliminate risk of breakage. Traditional stepped edge glass rooflights have a significantly higher vunerability to breakage due to their exposed edges.

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

Our fixed rooflight is easy to install. An integral perimeter gasket creates an air and water seal without the need for site applied silicone. The product is secured via screw fixing to the builders kerb externally and a matching cover clip is then applied to conceal the fixings.

We can offer a variety of bespoke shaped fixed rooflights. Please call us on 0116 2610710 with your requirements and we’ll be happy to assist.


All our rooflights satisfy the thermal performance criteria defined in the Building Regulations and achieve a high resistance to condensation under normal conditions. We can provide True U-value and Ud-values upon request.

The Duplus rooflight range is tested for weathertightness to BS EN 14351-1:2006 +A1:2010 clauses 4.2, 4.5 and 4.14 – Our test reports are available in our technical section.

As standard, the extruded aluminium perimeter frame is powder coated RAL 7016 dark grey matt or RAL 9005 black matt. We can offer other RAL colour options upon request.

Our glazing specifications incorporate clear low ‘E’ glass as standard, achieving a centre pane U-value of 1.1 W/m²K.

We deliver our fixed rooflights FULLY ASSEMBLED and fully weathertight. No time consuming assembly on site required. Furthermore, significantly higher security compared to kit systems.
