Pergola / August 27, 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.
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.
Look for pergola manufacturers that have been in the business for at least five years. The advantage of choosing such a manufacturer is that they can be more reliable in terms of fulfilling their product warranty or helping you with replacement parts at any time. Avoid Sizing Errors: Since most Pergola buyers are one time buyers many sizing errors are common. For example a common mistake is to assume the positioning of the 4 corner posts is the size of the pergola being offered. For instance if the four corner posts of a pergola are expected to sit on the corner of your brand new concrete pad that is 10 x 12 and purchase a 10 x 12 pergola you will discover on receiving your pergola kit that the posts are set at 8 x 10 to the outside corners.
