Our flat roof lantern is designed for large frameless roof lanterns between 3500mm and 5800mm in length. Our accredited structural silicone glazing techniques allow a design identical to our smaller flat roof lantern but with the introduction of a centre ultra slim rafter but without the requirement for internal framework to the products hips or ridge. When looking up at the roof lantern, 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.
Duplus large frameless roof lanterns are double glazed in clear HEATSOAKED 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.
Building Regulation Part Q (Secure by Design) compliant variants available.
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 our lantern & pyramid 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 on heatsoaked glass.
