Duplus Roof Lanterns

The highest quality roof lanterns Manufactured in the UK, maximising natural light with ultra-slim glass to glass hip and ridge joints. Accredited structural silicone glazing techniques allow the production of our leading frameless, low pitch aluminium roof lantern for flat roofs.

Due to the frameless design and structural bonding, there is no requirement for internal framework to the 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.

Our ultra-slim glass to glass structurally bonded joints make our frameless roof lanterns some of the slimmest systems on the market. We have over 60 years of experience in the design and manufacture of flat roof lanterns. Our wealth of experience and expertise allows us to produce a market-leading product range at competitive prices.

Security

Whether you are considering a new build or renovating a flat roof, we have a range of secure lantern rooflights suitable for your project. For new builds, we have our Secured by design Part Q roof lantern range with enhanced security features, fully tested to meet LPS 2081:Issue 1 accreditation.

Advanced Features

Duplus roof lanterns 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

Unlike traditional ‘stepped edge’ glass lantern rooflights, where the outer edge of the glass is vulnerable to breakage, we 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.

Also available without external cappings for a truly frameless external appearance.

FAQ’s

The steepest pitch we offer is 40 degrees, with a maximum length of 5.8m and maximum width of 2m. There is a single central glazing bar along each length.

Unfortunately, we do not provide openers on our roof lanterns. Our lantern rooflights are frameless and therefore no frame to carry the opening window. You may however wish to view our opening rooflight range that does have openers.

The advantage of roof lanterns over rooflights is a tendency to let more light in, due to the pyramid-style construction. Duplus provide frameless designs, so no framework at the hips or ridge, increasing the amount of light that enters the room.

No by their very shape, one wouldn't walk on a roof lantern! However, we do provide walk-on rooflights.

The width of external decorative trims that protect the glass on our lantern rooflights is 30mm wide overall.

Material Specifications & U-Value

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 on all our roof lanterns, octagons & pyramids double glazed units include 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 of heatsoaked glass.

All products are delivered FULLY ASSEMBLED. No need for time-consuming assembly on-site. Furthermore, significantly higher security compared to kit systems.
