Learn moreAs the perfect combination of present and past, this GGL SD5J2 centre pivot window from VELUX has a bright white painted internal finish which is ideal for modern interiors while the black external profile and glazing bar has been specially designed to suit conservation buildings. It coordinates with the surrounding original aesthetics and guidance and blends seamlessly into the roof.
Thanks to the top control bar with integrated ventilation, you can let fresh air in even when the window is shut. With a centre pivot function, this VELUX Conservation roof window is effortless to clean from inside by rotating 180° and locking into place with the built-in barrel bolt. It offers smooth operation due to the high-quality pivot hinges while the innovative Thermo-Technology™ offers energy efficiency by transferring less energy to keep your home warm.
Including an underfelt collar (BFX) for a watertight seal between the roof and the window and an insulation collar (BDX) for eliminating cold bridges and a reduction of heat loss, this VELUX Conservation roof window comes with EDJ recessed flashing which is suitable for use with tiles up to 90mm thick in profile. Providing a streamlined and sleek finish for your roof window, the recessed flashing ensures you can fit the window 40mm deeper into the structure so that there is minimal protrusion above the roofline. With click-on covers, installation is straightforward, quick and safe while the blue line indicates where you need to position your brackets.
With double glazing (70), this VELUX centre pivot Conservation window comes with premium features such as a UV filter, toughened glass, safety lamination and VELUX’s unique rain noise reduction. The UV filter protects your furnishings from the sun’s harmful UV rays which can cause fading while the toughened glass delivers extra strength on the outer pane to defend against external environmental forces. With up to 35dB of sound insulation, the rain noise reduction allows a peaceful night’s sleep without being disturbed by heavy rainfall while the safety lamination stops the glass from falling into your room in the event of accidental breakage.

Question:
does the Conservation range have the option of solar powered motorised operation for opening and blinds. We live in a Conservation area and currently have Ten top-opening Heritage Velux windows. We would like to add another one in our bedroom but as it will be high up we need a blackout blind and electric operation as it will be too high to easily operate manually. We have been told by someone that the Conservation range would look very similar but can be motorised - is this correct? Please advise.
Answer:
Yes, many VELUX Conservation GGL windows can be upgraded with a solar conversion kit for remote-controlled opening, and solar-powered blackout blinds are also available. However, compatibility depends on the exact window model and code. This window is a manually operated, centre-pivot model, so please provide the full code of your existing Heritage windows—or the proposed new window size and code—and we can confirm whether the solar opening kit and blind are suitable.
Question:
I'm replacing a ggl2 window with a conservation window does this mean I have to cut down the existing inner lining by 40mm for it to fit ?
Answer:
If you're replacing an older VELUX GGL-2 MK08 with a VELUX GGL MK08 Conservation Window, you won't necessarily need to cut down the existing inner lining by 40mm. The structural frame size remains the same (780mm x 1400mm), so it should fit the existing roof opening. However, the conservation window does have a black external conservation profile, an external glazing bar, and slightly different frame/profile details compared to older GGL generations. These differences might require minor adjustments during installation, but not an automatic 40mm reduction. You would only need to cut down the existing inner lining if the old lining was fitted very tightly to the frame, or if you're fitting a new VELUX lining kit and need to achieve the current recommended lining geometry. If you can provide the full code from the old data plate (for example, GGL-2 MK08 3059 or similar), we can check if there are any frame-depth differences between that model and the current conservation window.
Question:
Is this still fitted like a normal velux?
Answer:
Yes, the fitting is the same it's just the colour and the bar down the glass that's different
