Description

The Duplus Roof Lantern

The highest quality contemporary roof lanterns manufactured in the UK.

Ultra-slim glass-to-glass, structurally bonded hip and ridge joints, make our frameless roof lanterns some of the slimmest systems on the market. These 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, there is no requirement for an internal framework. When looking up at the roof lantern from the room below, the external glass cappings remain unseen. This gives the internal finish of the glass-to-glass joints a sleek, ’frameless’ and contemporary aesthetic that is truly jaw-dropping.

Duplus has a wealth of experience and expertise allowing 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 roof lanterns 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 roof lanterns, where the outer edge of the glass is vulnerable to breakage, we fully enclose the double-glazed units within the perimeter aluminium 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 reducing maintenance requirements.

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

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, octagonal & pyramid 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.

For larger sizes, please visit https://duplus.co.uk/product/lantern-rooflight

All our roof lanterns are delivered FULLY ASSEMBLED. No need for time-consuming assembly on-site. Furthermore, they are significantly more secure compared to kit systems.

FAQ's

The biggest roof lantern we manufacture is 5.8m x 2m external kerb dimension. There is a single central glazing bar along each length.

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.

Not at all. Any glazing primarily south / south west facing, will attract a lot more sunlight and therefore solar heat than glazing facing any other orientation. In such instances, we would recommend incorporating high-performance solar control glazing, as it will retract most of the solar heat, whilst maintaining maximum natural light.

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 54mm wide overall.

Not necessarily. This can spoil the aesthetics of your frameless lantern. There are many other ways to achieve the required ventilation. Most of your ventilation will come from windows, sliding doors or bi-folding doors. On a warm sunny day, you will most likely have the windows and doors open. This will provide ample ventilation. If you are looking to achieve cross-ventilation, you can incorporate ventilation within the upstand, just below where the rooflight sits.

For external cleaning we can help. We can apply an easy clean coating to the glass which will help keep the glass clean. However, you may hear of ‘self-cleaning’ glass. There is no such product on the market. Most products only help reduce maintenance periods and still require periodic cleaning. However, in most instances easy clean will help keep the glass looking cleaner for longer. Internally, the lantern will require cleaning with warm soapy water but usually no more than once a year.

The height for a 30 degree lantern at 1 metre wide, including packaging is approx. 400mm and the height for a 40 degree lantern at 1 metre wide, including packaging is approx. 540mm.
