Pergola / August 28, 2018 / JulietteHughes
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.
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. Comparative Study of Roofing Materials for a Pergola Permanent structures like metal roofs are difficult to change but they can be repainted. Fibreglass and clean plastic materials may change colour after a period but they can be discarded and new ones can be installed easily.
Before commencing on the project finalize first where you would like your pergola to be placed and what kind of design and style you would like it to be. Assess the prospective locations for your pergola and determine which is best by considering the piping system of your home or garden; you must avoid putting up your pergola in places where it could possibly do damage to the pipes underneath the ground. Another very important thing to consider is the purpose for your pergola. Do you want it to be an extension of your home? Do you want it to be a place for welcoming guests? Or do you want it to be your little shady haven in the middle of your garden? This should help you determine your location. Decide also on the kind of design and style of your pergola.
