Pergola / August 24, 2018 / JulietteHughes
Plastic and Fibreglass Another variation of roofing for pergolas includes using plastic or fibreglass. The advantage of these options is that they are lightweight and inexpensive. They may also be easily cut to size and allows the light to filter in depending on the colour of the roof. They also protect the pergola from the harsher elements of the weather including the rain and snow. Also ultraviolet radiation may be reduced when using these two options. Although plastic may not be a green choice Fibreglass can be manufactured from recycled materials. Polycarbonate Polycarbonates are thermoplastic polymers which can be easily moulded and has a high impact resistance along with other advantages such as heat resistance ease of shaping flame retardancy and toughness.
The reason is pergolas are always sized based on their roof size. And in most cases pergolas are recessed back from the roof edge anywhere from 8 inches to a couple of feet depending on the design (commonly 12"). Custom design or sizing can be a good idea to get a suitable pergola for your place. Look for manufacturers that insist on shop drawings prior to building and take the time to check everything repeatedly and make sure that all measurement and details are agreed to in writing ahead of delivery time. Assembly required/Assembly Instructions: Make sure you have collected assembly instructions from the manufacturers.
The pergola has evolved from its famous brick and stone posts of 19th and 20th century to modern wood designs of the 21st century. The idea of modern wood design of pergolas is its affordability and increasing popularity in modern garden designs. But because brick and stone are weather resistant hardwoods such as Western Redcedar and Coast Redwood are used instead to match with the pergolas made of brick and stone. As the normal use of a pergola is being an arbor for vines some architects introduced pergolas as a structure made as a protection from rain or direct sunlight.
