Optilight® Skylight Window Codes
A common question that we are asked is “How do I find my Optilight® Skylight Window Code?”. Optilight® roof windows are commonly installed in loft conversions and open plan kitchens.
Finding the right 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.
IF YOU NEED ANY ASSISTANCE IN FINDING YOUR WINDOW CODE, THEN PLEASE GIVE US A CALL ON 0161 524 6402, email us at team@skylight-blinds-direct.co.uk or SUBMIT SIZES
Once you have confirmed your window code, go straight to the Optilight® Skylight Blinds category here.
