Notching: Another important point to consider is notching. Notched pergolas last for longer times and have greater wind resistance capacity. 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 Pergola`s timbers has hidden stresses in it (quite common). as it weathers over the years. it will turn. twist or sag. This will cause your beautiful Pergola`s lines to be ruined.
The durability of pergola depends on the materials chosen for its construction. As the roofs are permanently exposed to the elements of nature. the paint chose may fade easily. Also. materials such as fabric may fray or fade and plastic or fibreglass roofs may get warped or change colour.
Painting your Pergola. Anything that is exposed to the harsh elements of nature will eventually need protection. Painting is one of the best ways to provide this protection. It gives colour to the wood and also conceals some of the natural defects and characteristics that may stand out obscuring the real beauty of the wood. Paint is also beneficial because they prevent moisture damage and rust. Acrylic paints are the best choice for painting pergolas as they provide the best protection.
Pergolas made of quality timber tend to be a bit costlier than those made from less decay resistant woods. Your first real decision is how long you`d like the structure to last. Once you determine this. see if the manufacturer has warranties that match your requirements. If so. then you can move on to thinking about size and design and the orientation of your pergola. Most reputable pergola manufacturers will allow you to send in pictures of your backyard. They will also allow you to ask any questions regarding the product and its installation procedures. A good percentage of pergola installation requires some customization. Take the time to make your investment in an arched pergola fruitful by taking a few minutes to make sure the dimensions and the positioning is thought out.
