Pergola / August 25, 2018 / JulietteHughes
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.
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.
Although in earlier times pergolas were constructed using brick and stone pillars modern designs employ weather resistant woods such as western red cedar or coast redwood. Pergola roofs may range from simple flat traditional roof elaborately curved roof pitched roof gabled roof or a gazebo style roof. Roofing materials There is a variety of materials that may be used to roof a pergola. The choice of roofing materials depend on the size shape and style of the structure. The durability and robustness of the construction depends on the materials that are selected for this purpose.
