Which suits my window?

Pick your window to see what suits it, what to watch for, and how each one looks.

Every picture on a sliding door

  • Wave curtains, sheer and blockout, ivory. Sliding door.

    Wave curtains, sheer and blockout

    Good for: Soft light by day, nearly dark when the blockout is drawn

    Watch for: A thin edge of light can show at sides and centre; needs room to stack beside the open panel

  • Vertical blind. Sliding door.

    Vertical blind

    Good for: Louvres turn for light and draw to one side to clear the door

    Watch for: Needs stack-back room; a blind fixed in front must not trap the handle

Bay, French doors, a high bathroom window or something else? Describe it in your own words and your installer will advise.
