To order louvres only, you would need to find the design and colour you are interested in on our website. On the order form on the right hand side of the screen, select 'louvres only' from the headrail section.
The order form will then ask for the drop of the louvres and the quantity required as well as giving the options available.
As the drop of louvres isn’t the overall drop of the blind, you only need to enter the size you wish your louvres to be. All of our louvres are 89mm wide.
