Pergola / August 27, 2018 / JulietteHughes
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.
Traditional pergolas can be transformed into modern style by replacing its roofing with transparent materials. There are several transparent materials which can be used as roofing such as Plexiglas sheets complete-transparent covers and glass panels. Plexiglas sheets can be used if you want protection from rain and direct sunlight without heating the sitting area of the pergola. Complete-transparent covers are used if you want to keep the traditional style of your pergola but still provide the protection you need from rain. On the other hand the glass panels can be used if your pergola is located in an open area without worrying about falling tree branches or fruits.
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.
