So What is the Solution?
All these situations could have been avoided with one solution, a cover over the pergola. I can hear some of your thoughts now… "A cover takes away from the pergola’s appearance." "My pergola was constructed so the slats would block the sun at the right times of the day." There may be some truth to these thoughts, but what if there was a way for a pergola to provide shelter, allow sunlight in, AND still look like a gorgeous piece of outdoor design? There is! Multiwall sheets, often referred to by the brand name of Polygal, are a structured sheet product available in double and triple layered configurations and manufactured in various colors and degrees of transparency. Polygal allows sunlight in but provides protection from unwanted elements, such as rain. Thermogal, a specially designed polygal sheet is commonly used in bronze or clear when covering an outdoor area. Clear Polygal is less noticeable because of its transparent nature. It also provides protection from rain and allows sunlight in. Bronze Polygal also provides protection from rain but is tinted and keeps the temperatures under the material cooler. The real question now is: why would you build a pergola without a cover?What Products Should I Use?
