Outside, cedar has natural weather-resistant properties that make it a good choice for siding, shingles, decking, greenhouses, arbors and fences. It’s considered to be a “durable” wood that can withstand exposure to the elements. It is also a great moth repellent.
Cedarwood essential oil is known to repel spiders, lice, gnats, ticks, mosquitoes and fleas. As an added perk, cedar also provides a clean, woody scent that will make everything it touches smell nice.
Cedar thrives in damp climates, enabling it to withstand many conditions. Cedar doesn’t shrink, swell, warp, or decay even when there are severe changes in weather, which makes it such an ideal choice for exterior siding. Cedar is sound resistant. Cedar is a porous wood, which gives it the ability to absorb noise.
In outdoor structures that are not in contact with the ground, such as decks, gazebos, pergolas and fence boards, cedar may last 30 years or longer. When in contact with the ground, such as when it’s used for fence or support posts, it can last between 15 and 20 years.
The “phenols” also are responsible for Cedar’s natural resistance to moisture, decay and insect infestation. The natural resistance provided by the oils and acids are what make these species more popular in outdoor applications. Properly finished, cedar will last for decades even in harsh environments.
