Roof Lantern

Our accredited structural silicone glazing techniques allow the production of a Glass lantern rooflight without the requirement for internal framework to the products hips or ridge. When looking up at the rooflight, the external hip and ridge cappings are designed to remain unseen. The internal finish of the glass to glass joints creates a sleek, ’frameless’ contemporary aesthetic that is truly jaw-dropping. If preferred we offer a lantern without the external hip and ridge cappings and therefore glass to glass joints externally as well as internally – see Capless Roof Lantern.

Duplus Lantern 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). Unlike traditional ‘stepped edge’ glass rooflights where the outer edge of the glass is vulnerable to breakage, our rooflights fully enclose the double glazed units within the perimeter framework to eliminate this risk. The top surface of the double glazed unit is flush with the external face of the perimeter frame to allow rainwater to disperse rapidly, minimising cleaning and maintenance requirements.

The extruded thermally broken Aluminium perimeter frame is powder coated RAL 7016 Anthracite grey matt externally and RAL 9910 white matt internally as standard. External hip and ridge cappings are fitted for aesthetics and are powder coated RAL 7016 Anthracite grey matt to match the external perimeter frame at the base of the lantern rooflight. 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.

Also available in lighter weight, higher performing triple glazing achieving a centre pane U-value of 0.6 W/m²K.
