Pergola / August 28, 2018 / JulietteHughes
Your pergola might be a simple feature in your garden or it might even be a more elaborate structure acting as a walkway or pathway or designed as a corner pergola. Materials to Build a Pergola Pergolas can be made of either wood stone or a combination of the two. Popular pergola structures of today feature wooden materials as they are much more affordable to construct. Weather-resistant wood will be important since this type of garden feature will most certainly be exposed to some harsh elements of weather. Western red cedar is a fantastic choice when choosing wood for your project.
Currently the materials that are used for roofing include metals plastic fibreglass polycarbonate fabric etc. Metal Roof The advantage of a metal roof is that it can be adjusted to the exact size and shape of the structure. A choice of metals such as copper aluminium or tin also helps to make an easy decision. Metals not only easy to cut and shape they also provide excellent protection from the weather conditions. However they also have some disadvantages such as disallowing light to enter the area or enabling the temperature to get too hot inside the area.
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.
