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.
Depending on the type of fabric used these pergolas may avoid the transmission of heat which could cause fading or damages to the roof. A tough and durable fabric that may usually be used in the making of the sails of a boat can also be used to filter ultraviolet rays and other harmful natural elements such as sunlight and heavy rain so that people can enjoy their investment for a long time.
