Controlling the heat in a stunning living room Linda’s client loved the living room window, until the afternoon sun came blazing through. One of the issues with this window is it is west facing and creates a lot of heat as well as light. Linda solved the problem beautifully with this a flat arched valance with pleated cascading ends. The view from the stair landing shows how stunning this window treatment is. What really makes a difference is the trim. The braided top tasseled fringe set the valance apart from the stripped panels. The secret here is each 122 inches long panel is lined with black-out fabric. The treatment looks just as beautiful when closed. The beauty is the black-out lining blocks the intense afternoon light and heat that normally pours through this window.
