What is an electric opening rooflight?

Electric opening rooflights are types of rooflights that use electrical systems to open or close. They feature all the benefits of normal rooflights, such as extra natural light and improved ventilation, with the added benefit of being able to open it with ease. 

With manual opening rooflights, you’re required to open and close them yourself.

Our opening rooflights are safe and reliable

Our opening skylights are designed to be safe and long-lasting. This rooflight comes with a bottom pane of 6.4mm inner laminated glass, compared to competitor products which often only feature a 6mm bottom pane. Larger rooflights come with a laminated glass that is 9.5mm or 11.5mm. Laminated panes are made by taking two plies of glass and bonding a film or interlayer in between them. Should they shatter, the layer between the two plies holds the glass in place, preventing pieces of glass from falling to the floor, ensuring safety.

If toughened glass was used, it would shatter into pieces that could cause injury. This means that our rooflight with laminate glass on the bottom provides a greater level of safety than those that have a bottom pane consisting of toughened glass only. The skylight can be easily positioned on top of the existing builder’s upstand and is manufactured to ISO 9001 industry standards in the UK.

How do electric and manual opening rooflights work?

Operated electrically or manually, this rooflight is connected to the mains power if electric option is selected and can be operated using a wall switch while there is the option to take advantage of remote or rain sensor. This makes opening and closing the rooflight efficient. If the manual option is selected a winding rod is used to open the rooflight. 

The rooflight uses single or tandem actuators, with the chosen option dependent on the size. Smaller rooflights will use actuators that are concealed, while large sizes will have an actuator that is more suited to heavy-duty use, and is, therefore, exposed.

If the ventilation option is chosen, then the hit-and-miss trickle vents which are manually operated can provide a ventilation area that is equivalent to 8400mm2. The manual rooflight is operated using worm gear via a pole which is sold separately.

Is this opening rooflight thermally efficient?

Both our manual and electric opening rooflights offers a centre pane U-value of 1.1W/,2K. This provides an exceptional level of thermal efficiency, making it one of the best on the market. If you’d like more information, view our blog ‘Are Rooflights Energy Efficient?’.

A modern design

The design of the rooflight stands out with a contemporary look and a sleek design. It has a flush fitting and a slim powder-coated frame, allowing the maximum amount of light to enter the room. The framework is slim and this means that it can barely be seen after it is installed following our fitting guide. However, you should make sure that all sizes are correct prior to making payment as all orders are made to order and so, the sizes cannot be altered once we have started the manufacturing process.

A 4-degree pitch is required as a minimum with the maximum pitch being 15 degrees. View our full range of pitched roof windows if you’re looking for a rooflight for a sloped roof.

Measuring and Installation guide

Please see fitting instructions below and downloadable PDF link at the bottom of this page.

Please note size you purchase from our website drop down menu is based on the finished external upstand dimensions. If you purchase a 1000mm by 1000mm from our website then your external upstand dimension would be 1000mm by 1000mm. We have 40mm tolerance all around built into our sizes so if your external dimensions were 1040mm by 1040mm this would still fit. The width of your upstand should be 75mm wide.

Our rooflight is supplied complete with uPVC frame that fixes to top of builders upstand and houses any opening equipment. We can supply a PVC upstand for an additional cost but you would need to contact us before order is placed.

Acceptable tolerance:

– Opening Glass Rooflight = rooflight size +40/-20mm

Please note self-clean option is only offered with some sizes and only works effectively at pitches of 10 degrees and above. The recommended pitch is 4 to 15 degrees. Sometimes customer may require installing at a lower than the recommended pitch.  If choosing to do this, then we strongly advise pouring water over the top of the skylight to ensure the flow of the water is smoothly off the unit before the rooflight is installed.  The only purpose of the skylight pitch is so the maximum efficiency of the self-clean coating is utilised (if selected) along with water and dirt to drift off.  When installed completely flat with no pitch then the water could pool on the top of the rooflight glass which won’t affect the performance or cause leaking. You may be able to see visible water when looking up at the skylight due to the lower pitch, however the warranty is still valid, but you may notice water pooling when looking up. Please be aware electric rooflights should not be fitted in high humidity areas, for example above a shower.

The glass balustrade gives us an amazing view onto the lake outside. So happy we ended up going for the frameless glass balcony from Toughened Glass Systems instead of one with posts

My job is to design the interiors for a lot of houses and a lot of times the hardest part was when the client wanted some really inexpensive rooflights that should look like some contemporary ones as well. That until I found Toughened Glass Systems and started working with them more and more. They have a lot of this kind of stuff at a very decent price, a price for anyone I can say. If you’re looking for cheap skylights for flat roofs or any types of roof lights, they probably have something for you.
