Pergola / August 25, 2018 / JulietteHughes
While traditional pergolas were intended mainly for beauty and comfort the current designs place more emphasis on providing protection from the harsh elements of nature such as rain and snow and ultra-violet radiation. The design of a pergola depends on the geographical location. Depending on the area the grade or the direction of the sun a pergola may be a gazebo an extension of a building an open terrace or a veranda that has grapevines criss-crossing a latticed roof. One of the most important considerations when designing a pergola is the roofing structure and shape The roof design on a pergola depends on the availability of direct sunlight as well as the geography and natural features of the region.
Glass panels although strong enough to serve as pergola covering dont work for all kinds of environments making them vulnerable to hailstorms. So it is always advisable to check your location before transforming your pergola with transparent insulations. Other types of roofing materials used in pergolas include metal pergola roofing materials which is considered the most durable and permanent roofing material and fabric deck pergola covers which helps in extending your outdoor furnitures life. While fabric deck coverings extend furnitures life it also reduces or protects you from direct ultraviolet rays.
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.
