First of all you must find the size and series of your Roto window. Remember: you do not need to measure the wndow - you just need the Roto window code.
The code may be inside a red, grey or blue tab or sometimes on a metal plate located on the sash (the part of the window that moves) see the images below:
The serial number will be similar to the following examples:
Depending on the age of your Roto window, the data plate and its position on the window varies, but it holds relevant information
If you are having problems locating the serial number please do not hesitate to contact us on 01949 845399 or at firstname.lastname@example.org.
The first 3 numbers listed in the example above tell you the series of the window. Each series requires a different blind.
The 435 series is a timber window with a centre pivot.
The 735 series is available in timber or PVC and pivots at the top third.
IMPORTANT: Blinds for series 4 and 7 (whether timber or PVC) are compatible!
The 320/339/559 all correspond the 320 series window. This is a timber window with a centre pivot. This series window has now been discontinued; however we do still sell blackout blinds and roller blinds to suit these common old style windows.
The 800 series is a 'means of escape' window and is top hung.
So to sum up! There are 4 different series blinds to order:
NOTE: The letters in the serial number you do not need to worry about. They can tell us the year the window was made and what material it is made from.
