My friend Sheila came looking confused. She had heard about many types of vertical blinds but did not know which one to decide on. I told her to opt for the best of Insulated Vertical Blinds. These are unparalleled as regards design, price and quality. To the world outside it shows white but it shows colour to those inside. The net result is energy savings. The best fabrics are strengthened with 100% (thermal) white backing that dispenses with the use of louver grooves. These are insulated and coordinated vertically. Generally bottom weights are sewn-in but separate weights as well as chains are available with extra cost. A variety of colours make matching easy. The bonus is embossed designs.
