VELUX Window Sizes – The Easy Guide!
VELUX Window Sizes
We have put together this very simple and easy to use guide to help make it easier for you to buy the correct size window for your projecty. This VELUX Window Sizes Guide will help you understand the product codes for VELUX windows, as we know that with the huge amount of sizes, model numbers and window codes, it can get really confusing! But with our easy to use VELUX chart you can discover the exact window you need in minutes.
It is also worth noting that if you are replacing an existing VELUX window then you can use the VELUX size guide to discover which VELUX new generation size code relates to your old roof window code. For example, if your current VELUX roof window code is GGL2, that means the new VELUX window code would be MK08. To help explain this further, take a look at the chart below.
The easy guide to your VELUX Window Codes
VELUX are known for their high quality products and latest in innovation, this also means that their product range will change as time goes on. Making what was once the latest window, an older style as a new one is launched. These continuous improvements over the years then means that older style VELUX windows then become ‘out of date’ in terms of the off-shelf support.
However, this will not be a problem because the new off-shelf VELUX flashings can be made to fit older style VELUX windows in most circumstances.
Old VELUX Window Sizes, Serial Numbers and Number Codes
Below are some examples of window size codes and window sizes, depending on when the window was produced.
VELUX dimensions refer to the external window frame and not the internal aperture in the roof.
- Window size 55 (W) x 78 (H) code 102 or CO2 or CKO2
- Window size 55 (W) x 98 (H) code 104 or 6 or CO4 or CKO4
- Window size 78 (W) x 98 (H) code 304 or 1 or MO4 or MKO4
- Window size 66 (W) x 118 (H) code 206 or 5 or FO6 or FKO6
- Window size 78 (W) x 118 (H) code 306 or 14 or MO6 or MKO6
- Window size 78 (W) x 140 (H) code 308 or 2 or MO8 or MKO8
- Window size 138 (W) x 98 (H) code 804 or 7 or UO4 or UKO4
- Window size 114 (W) x 118 (H) code 606 or 4 or SO6 or SKO6
- Window size 98 (W) x 160 (H) code 410 or 3 or P10 or PK10
- Window size 134 (W) x 140 (H) code 808 or 8 or UO8 or UKO8
Where are the VELUX Brand Windows Codes Located?
Did you know that every VELUX rooflight made after 1968 will have a data plate attached to it, which gives exact information about the model. VELUX has created its own personalized stamp which consists of codes that will tell you exactly what type of window/rooflight you have.
The VELUX brand window codes are found on the top right-hand edge of the roof window when you open it. The data plate tells you the type of window and the window size shown through the code. As shown below in the example, 304 would be 78cm x 98cm and the bottom window code 4 would be 114cm x 118cm.
