With various finish, glazing and operation options to choose from, this VELUX GGL MK04 centre-pivot roof window features innovative Thermo-Technology™ which transfers minimal energy so your home can stay warm and comfortable. Ideal for transforming your small room with plenty of daylight, it includes click-on covers which ensure a speedy, easy and safe installation.
With a straightforward red and blue line bracket system, you can distinguish between standard and recessed installations. Providing seamless movement thanks to the high-quality pivot hinges, this VELUX centre-pivot window effortlessly rotates 180° and secures into place with a built-in barrel bolt so you can clean the outer pane from the safety of inside your home. With a convenient yet elegant top control bar, you can allow fresh air to flow into your home through the ventilation flap even when the window is closed while the filter stops insects and dust.
Including pre-mounted brackets, you can find the perfect interior blind to complement your colour scheme and fit your window so you can control the amount of daylight that enters your room. It simply clicks into position, and you can insert the pre-cut side channels.
What’s more, all the standard glazing options boast quality features including a UV filter, VELUX’s unique rain noise reduction, safety lamination and toughened glass. The rain noise reduction helps to ensure a peaceful night’s sleep without heavy rain noise on the window while the UV filter safeguards your furnishings against harmful UV rays which can cause fading. The toughened glass offers extra strength to the outer pane to protect against external environmental factors while the safety lamination inhibits the glass from falling if it were to accidentally break.

Answer:
The correct flashing kit depends on the roof profile and pitch.

Question:
VELUX GGL MK04 207021U White Centre Pivot Electric Window INTEGRA - 78cm x 98cm - is this window anthracite colour on the outside please?
Answer:
Yes, the VELUX GGL MK04 207021U White Centre Pivot Electric INTEGRA window has a grey powder-coated aluminium external cladding, which is the standard VELUX external finish and is generally described as anthracite grey/dark grey in appearance from the outside. The "White" in the product name refers to the internal white-painted timber finish, not the exterior. So in summary: - Inside: White-painted timber finish - Outside: Grey powder-coated aluminium cladding (dark grey/anthracite appearance) If you're trying to match existing anthracite windows or rooflights, this VELUX finish is typically a good visual match, although it is not supplied in a RAL 7016 anthracite powder coat as standard.
Question:
VELUX GGL MK04 2070 - IS this UPVC or painted wood

Question:

When the window is closed is there any ventilation?
Answer:
Yes, the VELUX GGL MK04 2070 White Centre Pivot Window does provide ventilation even when it's closed.

Question:
What does the guarantee cover, please? Mine is broken at the handle.
Answer:
The guarantee provided by VELUX typically covers issues arising due to manufacturing defects. However, it's important to note that it usually does not cover accidental damage or issues due to normal wear and tear, which might include a broken handle. To get the most accurate information on what your guarantee covers, I'd recommend referring to the original documentation that came with your VELUX GGL MK04 2070 White Centre Pivot Window. If you have misplaced this, our customer service team might be able to assist further or you may want to contact VELUX directly for clarification.
Question:
My ggl c04 electric windows work fine but the windows themselves have started to leak - they’re pitched at about 15degs. Do you sell just the replacement window (i.e. without the surround) compatible with electric opening mechanism? Thanks
Answer:
I'm sorry, but we do not sell the windowpane separately for the VELUX GGL MK04 3070 Pine Centre Pivot Window Laminated - 78cm x 98cm. We only sell the complete unit as they come supplied from VELUX assembled. If your window is leaking, it might be worth looking at how the flashing has been installed - if this is not correctly installed it can lead to leaking. You can refer to the VELUX Installation Guide for more details on proper installation. Here's the link to the guide: VELUX Installation Guide. If you continue to have issues, it may be best to contact a professional for an assessment.
Question:
What is the aperture size required for this window? Do you have a pdf drawing of the window. I only have 100cm on the length between horizontal trusses. I'm sure I read that the sizes 78 x 98cm was the outside size of the window but a message in this thread says it is plus 45mm on the 98cm length. Does the window come with a tile flashing or is that an extra?
Answer:
The dimensions of the VELUX GGL MK04 Centre Pivot Roof Window are indeed 78cm x 98cm. However, this refers to the external frame size. The actual structural opening required for installation will be slightly larger, generally about 20mm more around each side, so you would need to account for this when fitting the window. You can find more detailed dimensions and technical drawings in the downloads section of the product page. Regarding your question about tile flashing, it is not included in the package and needs to be purchased separately. You can find a suitable flashing kit on our website in the 'Pitched Roof Windows' category, or in the ancillaries on the right of this product page. Please ensure you select a flashing kit that is compatible with your specific roof material and profile.
Question:
Hi, please could you tell me if this product Will fit with original flashings ( if in good condition) with the already installed GGL 304 3000? Thanks
Answer:
I'm sorry, but the VELUX GGL MK04 2070 White Centre Pivot Window Laminated - 78cm x 98cm is not compatible with the original flashings of the GGL 304 3000. VELUX flashings are not compatible across different generations. It's recommended to use the appropriate flashings with the window model for a proper fit and to ensure the window functions correctly.
