Roto Skylight Window Codes

A common question that we are asked is “How do I find my Roto Skylight Window Code?”. Roto roof windows are commonly installed in loft conversions and open plan kitchens.

Finding the right Roto Skylight window code is really simple and in most cases no measuring is required. Window manufacturers attach a product plate to the frame giving you the window code.

Use the illustration below to give you an idea of what information should be on the plate. If you can’t find one, then simply measure the visible glass size, and use the table below to find the code, or give us a call, and we will ascertain the correct code.

Skylight Window Product Plate

The product plates for Roto windows are often in Red or Blue. Open the cover of them to reveal the information as displayed below. Although there is a lot of information only parts of it are relevant. All you need to note down for ordering is the Serial Number and Window Code. On the images below we have circled where these are.

If you cannot find the data plate follow the instructions below and note down the information required.

1) Measure the visible glass size, width first, then the drop in millimeters. Using the tables below find your window sizes in the visible glass width & visible glass drop columns. Once located look left of the table for the window code.e.g. in the table below 384mm x 544mm is Window Code 5/7

2) Check if the frame made from Wood or PVC? Look in the first column in the tables below for wood or PVC to choose any of the Series numbers.

Please note: The frame type must match the glass size. For example a window code 5/7 in a wood frame is a different size toa 5/7 with a PVC frame.
