When looking at houses, many people love the fact that somewhere in their lower level house, they will have a sliding glass door. But no one understands that once you move in your going to need to cover the slider, to avoid becoming a sitting duck! Sliders will not only allow tons of light to stream in, but privacy levels will drop dramatically. The initial discussion becomes do I deal with it or waste tons of money covering up this huge slider? There are many products out there on the market that could potentially be put up as a window treatment, but the price tag could have you second guessing your judgement.
