The Evo curtain and track system gives you a flatter, more modern looking curtain. Evo Curtains are made with a single reverse pleat, and with the addition of a pelmate, this curtain and track system gives you the equivalent insulation of a traditional curtain and pelmet. The single pleating means less fabric is required in your curtain, which gives the benefit of a smaller stack, when the curtain is open, thereby increasing the amount of light coming into your room, whilst enhancing your view outside.
