What is an electric opening skylight for flat roofs?
Electric polycarbonate opening rooflights are like traditional rooflights, but utilise electric actuators that allow them to open and close with ease. These actuators are controlled with a switch.
It’s created using thermally efficient materials, and can save you money on heating and lighting bills – our blog ‘Are Rooflights Energy Efficient?‘ covers this topic in more detail

Range Of Sizes
If your requirements fall outside of what we supply, we will happily discuss your options and further guide you should you desire. Standard sizes are available in 150mm increments starting at 600x600mm all the way up to 1800x1800mm.
Instructions To Measure For Builders Upstand Installation
Measure external builders upstand
Acceptable tolerance:
• Fixed / unvented domes = dome size +20/-20mm
• Opening / vented domes = dome size +40/-20mm
For example, height of the upstand should be 150mm high and the width should be 75mm if you are fitting on a builders upstand. As demonstrated in red above, your external timber size should match that of your purchased item (drop-down menu on our website) e.g both should be 900x900mm. If you purchase a 900mm by 900mm from the drop down menu on our website your external timber size as shown in red above (Measure here) should be 900mm by 900mm.
Instructions To Measure for Domes With PVC Kerb
Measure internal roof opening
Acceptable tolerance = dome size +20/-30mm
For example, the drop-down menu on our website allows you to choose the measurement you require. If you buy with a 150mm or 300mm high upstand and you buy a 900x900mm from the drop down menu then your timber size (shown above in red) which is your structural opening size should also be 900x900mm.
*Centre pane U-value is a measure of the thermal efficiency of the glazing type.
#Ud-value is a measure of the thermal efficiency of the whole rooflight (calculated in accordance with NARM Technical Document NTD2).
~Glass glazing option is not available with the access hatch option and limits other opening options depending on size
Part L Building Regulations require a U-value of at least 2.2W/m2K: Brett Martin Daylight Systems recommend the use of at least triple skin rooflights in all applications
Tint Guidelines:
The light transmission properties of the polycarbonate rooflight are displayed in the table below:
Clear – high visibility
Maximum transmission of light
Pristine vision of sights and all objects through the dome via maximum clarity
Opal – diffused light and solar control
A unique combination of high levels of diffused light transmission and privacy.
Ultimate prevention of solar glare and mass reduction of solar heat gain
Reduced visual capacity by impairing vision through the dome of sights and objects
Patterned – privacy
High levels of light transmission combined with personal privacy
The diffusion of natural daylight
The heightened impairment of vision through the dome
Upstand:
Builders upstand (opening / vented)
The dome comes with a uPVC frame. This attaches to the top of the builders upstand and all housing ventilation/opening equipment.
150mm uPVC
For mounting at roof surface level, providing 150mm of waterproofing height (exact kerb profile varies with specification)
300mm uPVC
Typically mounted below roof surface level, to provide 300mm of height for waterproofing and insulation
Trickle Vents
2 manually operated hit and miss trickle vents providing combined 8400mm² equivalent area ventilation. Please note trickle vents cannot be supplied with 450mm by 450mm size.
The design life of actuators is at least 10,000 cycles and where present, electrical actuators are guaranteed for 1 year. Our units are guaranteed for a period of 10 years but are anticipated to continue to be fit for purpose beyond this. We expect them not to distort and lose weather-tightness, not to become perforated or lose any major structural efficiency for around 20 years.
Delivery & Lead Time
All sizes below are on a 2-3 working day lead time. For all other sizes, lead time on application. Usually, other sizes will be 3-7 working days but this depends workload.
If remote and rain sensor options are selected lead time would be around 5 working days.
Please note that the transport company is not responsible for delivering inside the property. They are not insured to do this so you will need to ensure an appropriate person is designated and on site to offload the product out of the vehicle once the driver arrives. We do not recommenced arranging equipment and installation until the item has been delivered.

I installed a 1400 x 1200 Flat Rooflight for a client and can thoroughly and totally recommend TGS.
First the ordering process was clear and simple. Then, as it was the first time I had used this product and my determination to understand the fitting process and to ensure a robust and leak free product, I contacted their technical section who couldn’t have been more helpful. Result was a perfect installation that looks pleasingly simple, stylish and floods the very contemporary extension with light. Thanks guys - I’ll certainly recommend and use you again.

I've used flat roof lights from Toughened Glass Systems in three residential projects and they've not only enhanced the visual appeal , light distribution and ambiance of our living rooms, but they've been holding on very well over time. The value for money and service provided by them has always been on point so I'm happy to recommend them.
