Our Secured By Design roof lantern has been tested by a leading independent testing facility, BRE (Building Research Establishment) and achieved LPS 2081:Issue 1 certification. This means that our secured roof lanterns conform to the requirements set out in The Building Regulations Approved Document Part Q (Secured by Design). The test involves a timed manual attack using various methods to determine whether the rooflight can withstand an attack by an intruder.
To achieve secured by design Part Q certification, our rooflights are double glazed with an outer pane of clear toughened and HEATSOAKED safety glass and an inner pane of clear laminated glass. 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).
Unlike traditional ‘stepped edge’ glass rooflights where the outer edge of the glass is vulnerable to breakage, our secure roof lanterns 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.
As with all our rooflight products, this Secure By Design roof lantern 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.
This roof lantern is also available without external cappings for a truly frameless external appearance.
Our accredited structural silicone glazing techniques enable us to produce our 30-degree frameless low-pitch Secured By Design roof lantern. Frameless in design and no requirement for an internal framework to the product 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.
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.
All our rooflight glazing specifications incorporate clear low ‘E’ glass as standard, achieving a centre pane U-value of 1.1 W/m²K. Please refer to our FAQ section for an explanation of heatsoaked glass.
Delivered FULLY ASSEMBLED. No need for time-consuming assembly on-site. Significantly higher security compared to kit systems.
If you require a higher level of security enhancement, we can offer a Secured By Design rooflight to suit.

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.
