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.

Fibreglass and clean plastic materials may change colour after a period but they can be discarded and new ones can be installed easily.
You can generally save more by using plans rather than kits. However when you use plans you still have to buy the materials and tools from the materials list that accompanies the plan. In this case the materials you will buy are not yet fitted so you will have to cut and shape them yourself. But if this is not an issue with you because you are fairly skilled and have the basic tools then using plans would be very cost-efficient. Kits on the other hand cost a lot more than plans. If you have below average skills you might want to spend on a pergola kit. The kits will already come with a detailed how to instruction list basic tools and cut or shaped materials that are supposed to fit perfectly when assembled correctly.
