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.
2. Do the pergola plans take into account the sun? Since the purpose of the pergola is to protect people under it it is crucial that you take into account the path that the sun takes when it goes over your garden. If you want it to catch the sun you will still have to take the path of the sun into account. Therefore you should only approve the location of the pergola after you have confirmed that the suns path has been analyzed. 3. What materials do the pergola designs specify? Traditionally wood is regarded to be the best material for building pergolas. The reason for this is the fact that wood pergolas turn out to be cheaper than pergolas made from other materials.
Furthermore wood is the most organic material that you will find for building pergolas. Other materials that people have been known to use include vinyl and aluminum. 4. Have the pergola plans been made to scale? Depending upon your garden the size of the pergola would also vary. It would be entirely pointless if you end up with a pergola too big or too small because it would fail to serve its primary purpose. Hence make sure that the size of the pergola corresponds to the size of your garden before giving the go ahead for its construction. 5. Which shape do the pergola plans give your pergola? Finally you will also have to make a choice between different shapes of the pergola.
