Pergola / August 28, 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.
So while buying wooden pergolas ask their manufacturers if they are partially notched or fully notched. Buyers should be aware that notching creates interlocking joints and this fortifies the structure. Also notching insures that all your timbers stay straight and true over the decades because they cannot move. Most manufacturers skimp on notching partially or completely to reduce their construction costs and will tell you that hardware will take care of the issue. It does not. If just one of your Pergolas timbers has hidden stresses in it (quite common) as it weathers over the years it will turn twist or sag.
The choice of materials to cover or roof the pergola depends on the buyers instincts as to the choices for durability permanency and availability. In tropical Australia zinc-galvanized corrugated sheets do not reflect infrared or ultraviolet much. White roofs reflect better. White or soft shades are better colors for a cool roof. As the Earth seeks to get greener the best choice of course is to enjoy traditional open roofed pergolas. Painting your Pergola Anything that is exposed to the harsh elements of nature will eventually need protection. Painting is one of the best ways to provide this protection.
