You need to see if you can find a makers name on either the door or frame. The reason for this is there are many shades of white. If you can tell me the name i can then tell you the colour. If you measure to the outside edge of the bead and deuct 10mm this is the size needed. There are some very old Veka profiles which must have 15mm deducted to allow for bead holders. If the panel is ruined and you are ordering a new one you could simply drill a 3/16 hole about 3mm and push a matchstick through flush with one side and mark the other. This will give you the thickness of the panel. (In place of removing panel)Panes are Normally 20, 24, or 28mm if you cant buy a panel locally we sell a panel for £45.50 or £60 including postage.
