These can be quoted assembled with ripple iron, in which case all you have to do is affix it over your window. They can be bought in any stage  of  completion from just the  side peices to it being complete, framed and screwed  with or without the ripple iron and flashing. Our standard range is manufactured from 90x35mm pine and are trenched around a solid piece of marine ply and glue/screwed/nailed permanently together. Dropper styles are interchangeable upon request, and any type of scroll work can be placed into the slatted section. We also have a myriad of brackets to choose from, or you can always use your own design.
