With the passage of time and the action of nature, absolutely all building elements deteriorate. The same is true for wood, although depending on which one we choose, times vary widely.
Each type of wood has its advantages and disadvantagesIn addition, not everyone is exposed in the same way, as there is no universal option and it is better that we choose based on our needs, the environment to which it will be subject and the budget.
Most Common Conifers
O cedar, a sequoia it’s him cypress There are three woods that we can find in outdoor work without specific treatments.
Both cedar and sequoia are stable woods, do not deform normally if the drying was adequate and have considerable natural resistance. However, they can break when working with screws and tend to release tannins to the outside if they are not properly sealed, which can deteriorate the layers of paints and varnishes applied.
The cypress, a little weaker, has similar characteristics. It has a much lighter color.
Price and availability are directly related to the area we are in and how close we have farms to these open-air woods.
The white oak
White oak has less porous wood than other types of oak. This makes it difficult for moisture to advance and therefore decompose. As with previous woods, care must be taken when working with fasteners, such as screws, as they can break.
Aesthetically it is a much appreciated wood.
Most Common Treated Woods
One of the most frequent options is wood treated in autoclave, mainly pine. After this treatment, the wood substantially increases its resistance to moisture, insects and fungi, although this does not mean that it cannot break or deform.
The price is generally not high when compared to other alternatives.
High density tropical woods
There are a number of woods, imported mainly from South America and Africa, with a great resistance to humidity, fungi and insects due to their high density. Ipê, teak and mahogany are three of these woods.
In addition, this high density offers resistance to shocks and deformations.
Their price is usually quite high, especially considering the expansion of demand for these woods for external use.
