Our bespoke walk on glass rooflights has been designed to visually enhance the appearance of dark cramped spaces which can benefit from natural light. RLRL walk on rooflights are the most seamless design available on the market.
RLRL rooflights are supplied with a 33mm toughened laminated top pane making them one of the most thermally efficient and noise reduction walk on rooflight glass products on the market.
The walk on glass product is designed and manufactured in the United Kingdom so you can be assured it is manufactured to the highest quality and complies with the relevant UK standard.
The glass walk on rooflights can be customised further to include options below:
- Anti slip sand blasted top pane
- Clear glass (standard)
- Privacy satin glass
- Custom sizes
This unit was designed from the ground up to fill the need for a high-quality walk-on skylight at a competitive price in the UK. A skylight that, whilst relatively inexpensive, is suitable for the most demanding of commercial applications. With 33 mm toughened glass fitted as standard, this skylight can be walked on by roof maintenance teams without any fear of accident or injury (assuming normal precautions are observed). It is also eminently suitable for rooftop gardens, as well as flat-roofed residential properties with rooftop recreational areas.
Walk On Skylight Key Benefits
Walk On Skylights have a number of benefits to offer that make them a potentially good choice for a variety of different applications:
- Easy Installation – Our walk-on skylights are designed to be very easy to install. Assuming that you hire a suitably qualified and experienced professional, you should not expect to encounter any issues when installing these units in your commercial premises.
- Safe and Secure – The thick, toughened glazing ensures that these skylights are completely safe to walk on and are not an easy target for opportune thieves.
- Energy Efficient – The thick, toughened glass also helps to deliver exceptional energy efficiency performance, in combination with the well-constructed frames and high-quality seals. For commercial applications where heat loss is a potential concern, our bespoke walk-on skylight is an excellent option.
- Decent Noise Insulation – In addition to security and energy efficiency, the toughened glass with which these skylights are fitted performs one more vital function: it helps to insulate the interior of your property from external sources of noise disturbance.
- Smart Aesthetic – Fitted flush to the roofline, our walk-on skylight is the perfect choice when aesthetic concerns are to the fore. If you wish to retain the clean lines of your building's existing architectural features, these skylights will perform flawlessly.
If you would like to make sure that your new walk-on skylight project is an unqualified success, our bespoke units are just what you need.
Installing Your New Walk On Skylight
Any competent builder or roofer in your area should be able to complete the installation of your new skylight without any difficulties. Designed to be installed on an insulated upstand, full instructions are provided with each unit. For more details, please see the Fitting & Measurements tab or feel free to pick up the phone and speak to us if you prefer.
Easy & Hassle-free Fitting
The walk on rooflights we supply can be easily installed by a roofer or builder. We supply this complete and easy-to-follow step-by-step guide, including technical support documentation, in order to facilitate the installation.
Each walk on glass rooflight that we supply can be conveniently installed on an insulated upstand coupled with an support timber trim, which your roofer/builder can provide.
Any installation-related diagrams and information you see on this page is for general guidance purposes only as each project can vary in terms of design and construction according to the architect’s drawings. Furthermore, upstand dimensions and design may also vary based on the architect’s drawings and insulation specifications. However, your walk on rooflight may be custom-designed at an additional cost to suit wider upstands featuring larger than 100mm overhangs, should you require.
General Installation and Measurement Guidelines
RLRL flat walk on roof lights are very easy to install by a competent roofer or builder. Below, you’ll find a simple fitting guide explaining each step. In order to get technical support, you can contact us via email or give us a call. Please note walk on skylights are much heavier than standard non walk on rooflights.
How to measure the opening
Before you can buy your rooflight walk on glass, the first step is to take measurements of the structural opening where you want the glass walk on rooflight to go. It is recommended that at least 5mm tolerances should be allowed all around the structural opening in order to let the walk on glass rooflight’s bottom pane fit effortlessly into the opening.
For instance, if you purchased 1000mm x 1000mm walk on rooflight from our drop down menu this will be the size of the top pane of glass that rests on top of the upstand. The bottom pane of glass will be 100mm smaller all around which would make the bottom pane 800mm x 800mm. You would make the structural opening 810mm x 810, upstand width up to 65mm wide and height 150mm high in this example.
For all walk rooflight units purchased from our website, the top pane has a black 100mm boarder and a 100mm overhang all around. The top pane can be made bigger for bigger upstand width if required at an additional cost.
For clarity as another example, if you purchase a 1000mm by 2000mm from our drop-down menu on our website. For this size walk on roof window the bottom pane that slots into the structural opening will be 100mm smaller all around making it 800mm x 1800mm which means your structural opening should be 810mm x 1810mm. Upstand width should be up to 65mm wide and 150mm high, allowing a 35mm lip on each side of the top pane as per diagram below. The top pane walk on glass panel will be 1000mm by 2000mm.

How to prepare your roof
The walk on skylights are secured onto a timber kerb which will be prepared by your roofer or builder as part of the flat roof construction process.
It’s important for the timber upstand to protrude at least 150mm above the roof. Ensure that the pitch is at least 5°, which is deemed sufficient to allow water to flow down easily and prevent water pooling on top of the glass. For walk on rooflights many customers install that product flat, this won’t affect the performance of the walk on glass but may result in water pooling until it’s dry.
How to install your walk on roof lights
The last step required to finish the roof before you can install your walk on glass roof light is to apply a roof covering to the upstand’s side, which makes it weatherproof (illustration below).
Just to quickly reiterate, it’s important to get the timber upstand protrude by at least 150mm above the roof – the pitch should be 5° if possible, allowing rainwater to flow down with ease. Before sealing the product with silicone, water can be applied to test the flow off of water, if pooling occurs a higher pitch may be required. If a self-clean option is selected, please note it works effectively at pitches of 10 degrees and above.
Apply a reasonable amount of compatible silicone to the Upstand’s top part according to the silicone supplier’s data sheet, after which you can place the top pane rooflight onto the top of the upstand . Apply pressure all around the 100mm overhang so that the silicone spreads evenly and seals any gaps. Finish the silicone with a silicone finishing tool.
Next, the bottom pane needs to be supported on all four sides after it is set in place with the support trim fitted and bonded prior to the plasterboard. Secure the aluminium angle or timber batten to the timber structure. Apply compatible structural silicone between the bottom aluminium angle trim’s or timber battens surfaces and the bottom pane of glass according to the supplier’s data sheet, and firmly secure into place. Wipe away any excess silicone using a finishing tool. The trim can then covered with plasterboard.
The bottom and top panes of glass at this stage are fully supported. Only sealants compatible with the top of the upstand, glass, aluminium angle trim and setting blocks should be used. Sealants used should be compatible with Dowsil 3363. Dowsil 791 low modulus weather proofing silicone and Dowsil 895 Structural sealant are compatible with Dowsil 3363. Some sealant suppliers may require primer to be applied to surfaces.
If required once the above is complete you can build up your roof decking material to make the rooflight flush with your roof decking as per the diagram below. Please note this last step below is not essential.
