A testament to modern design and the power of natural light, the VELUX CFU 2093 Fixed Flat Glass Double Glazed Rooflight is an effective flat roof window solution, whether your roof is flat or gently sloping with a pitch ranging from 2° to 15°. These sleek glass rooflights offer a discreet and contemporary look that seamlessly integrates with your architectural vision.
This new generation of rooflights features a remarkable 52% increase in natural daylight compared to older generation windows, ensuring your rooms are bathed in natural light all year round. This not only makes your rooms brighter and more inviting, but it will also help you reduce your reliance on artificial light.
Designed to withstand the elements, these rooflights offer dependable weatherproofing to protect your interiors from the harshest conditions. Their slim, modern profile is a sleek alternative to traditional glass domes while their double-glazed glass not only promotes energy efficiency but also excels in sound insulation, creating a tranquil atmosphere in your home. VELUX's high-performance insulation is integrated into the frame to give the best possible protection against heat loss and protection against thermal bridges. For safety, the inner pane is laminated, meaning that should damage to the outer pane occur, shards of glass will not fall into your home and risk injuring occupants.
These rooflights aren't just a favourite among homeowners; they are also ideally suited for buildings like schools, supermarkets, and other industrial properties, where their elegance and functionality shine through. And if durability is a concern, rest assured that these rooflights are scratch-resistant and remarkably easy to clean, ensuring they maintain their stunning appearance for years to come.
Please note:
Question:
What is the total build up height of the window when installed on a builders kerb?
Answer:
The VELUX CFU 080080 2093 Fixed Flat Glass Double Glazed Rooflight is designed to be installed onto a builder's kerb or upstand. VELUX recommends a minimum kerb height of 150 mm above the finished roof level. The rooflight itself projects approximately 150 mm above the kerb. Therefore, the typical overall build-up height from the finished roof surface is around 300 mm. However, please note that the final dimension could vary depending on the height of the kerb constructed on your site.
Question:
Is the velux fixing kits included in the item or needed to be purchased purchased separately in order to fit the window for CVU and CFU units?
Answer:
For the VELUX CFU and CVU flat roof units, the necessary installation fixings are included with the window system. Therefore, you do not need to purchase a separate VELUX fixing kit as you would for a pitched roof window. These units are designed to be fixed directly to the builder's upstand or kerb using the supplied installation components. Please ensure to follow the VELUX installation instructions for correct and secure fitting.
Question:
I would like to replace an Atlas rooflight with a Velux CFU 120120 on the existing builders kerb. I don't seem able to see anywhere the intenal dimension of the Velux rooflight to establih whether this would fit over the kerb dimension I have. Can you advise on this dimension please. Many thanks
Answer:
For the VELUX CFU 120120 2093 Fixed Flat Glass Double Glazed Rooflight, the crucial dimension you need to consider for an existing builder's kerb is the rough opening or internal kerb size. This should approximately be 1200mm x 1200mm. The CFU range is designed to sit on a builder's kerb where the clear internal opening matches the size code. In this case, a 120120 unit is intended for a 1200mm x 1200mm internal kerb opening. The external frame size is approximately 1415mm x 1415mm. Please verify these dimensions with your existing setup to ensure a proper fit.
Question:
Hello, does this window need a fixing kit or anything else when purchasing?
Answer:
The VELUX CFU 120090 2093 Fixed Flat Glass Double Glazed Rooflight is generally designed to be installed as it is, without a separate fixing kit. However, whether you need additional components can depend on your specific roof system and your roofer's preferences. For instance, you might need a fixing kit if you're using single-ply membranes (EPDM, PVC, TPO), if you want a VELUX-approved mechanical fixing method, or if you're strictly adhering to VELUX installation best practice / warranty guidance. I would recommend discussing this with your roofer or installer to determine if additional items are required for your specific circumstances. You can also refer to the VELUX installation guide for more information. Here is the link to the guide: VELUX CFU Installation Guide
Question:
Does this come with an Up stand?
Answer:
Yes, the VELUX CFU 080080 2093 Fixed Flat Glass Double Glazed Rooflight - 800mm x 800mm does come with an upstand. The upstand is designed to provide a secure and weather-tight seal between the rooflight and the roof surface. For additional details and installation instructions, you can refer to the product's Installation Guide.

Does the 600 x 600 flat roof velux need an insulated collar?
Answer:
The VELUX CFU 060060 2093 Fixed Flat Glass Double Glazed Rooflight - 600mm x 600mm does not explicitly require an insulated collar as part of its specifications. However, to ensure optimal thermal performance of your rooflight, it may be beneficial to consider supplementary insulation.
