Which Wood Lasts the Longest? Teak wood easily lasts the longest when used for outdoor furniture or decking. When properly maintained, it can last for the entirety of your life and years after.
The bristlecone pine provides us with our oldest trees: up to 5,000 years old! It thrives at high elevations in California. There is a mix of long-lived hardwoods (like oaks and hickories) and softwoods (like firs, redwoods, and yew) that live for many years.
Redwood and Cedar. While pine is the best exterior softwood for the money, Redwood and Cedar are better exterior softwoods for stability. Redwood and Cedar are pinkish, with heart redwood being a darker pink than Western Red Cedar.
Choose Rot Resistant Wood for Your Project
Well-known domestic examples include cedar, redwood, old-growth cypress, mulberry, yew, osage orange, and black locust. Tropical wood examples include ipe, lignumvitae, purpleheart, and old-growth teak.
Cedar wood projects typically last more than 20 years without splitting, rotting, or warping. White oak and teak are also long lasting woods that are resistant to decay, twisting, cracking, or warping.
The best water resistant wood types & species. Iroko, Oak, Western Red Cedar, Cherry, Maple and heat-treated woods are just a few examples of timber that boast excellent dimensional stability and high resistance to shrinking and warping in the face of moisture.
While redwood or teak certainly qualify, five more common lumber species that also stand up well to sunlight, moisture and wood-boring insects are Western red cedar, Spanish cedar, cypress, white oak and mahogany. Red cedar tends to be knotty, but it's affordable and widely available.
While similar to standard exterior plywoods, marine plywood is the highest quality (AA, AB, and BB), constructed from wood without knots. Eliminating the knots in wood improves durability because it practically eliminates the possibility of water pockets forming within the wood.
Teakwood is one of the hardest and most durable of all natural woods. It is resistant to rotting, sunlight, rain, frost, and snow, making it suitable for outdoor construction and furniture. However, it is expensive and sometimes hard to find.
Of locally available woods, Black Ironwood is typically the strongest type of wood you can find in America. It's found in Florida and has a 3,660 lbf (16,280 N) Janka rating. Other strong North American woods include species of hickory, maples, oaks, walnuts, and beeches.
Pine. Pine wood is probably the cheapest wood that you can get on a consumer level, but it is also one of the best wood options when high strength and low cost are needed. Pine wood is sourced from the dozens of different pine species that grow natively around the world.
Heirloom-quality handmade wood furniture should last more than a lifetime. In fact, it can last for decades if properly maintained. This type of wood furniture is more likely to reach the “antique” milestone, meaning it can last 100 years or more.
Wood is naturally very durable--in moderate, sheltered environments it can last for thousands of years without substantial change. Biological deterioration is found principally in the form of insects and fungi.
It is the world's oldest surviving wooden structure. Horyuji was constructed from Japanese cypress that were roughly 2,000 years old. It has been 1,300 years since the cypress were cut down, and the wood still stands firm.
Since it's widely available, fir can be useful for those running a slightly tighter budget. It's one of the cheapest woods for outdoor use. If you're a woodworker or DIY garden furniture maker, this species also works and machines well, in addition to holding finishes easily — whether a clear varnish, stain or paint.
Naturally resistant woods that are commercially available include black locust (Robinia pseudoacacia), teak (Tectona grandis), ipe (Tabebuia spp.), California redwood (Sequoia sempervirens) and bald cypress (Taxodium distichum). These have the highest resistance to rot over time.
The logs that float are less dense than the logs that sink. Testing out a few samples of wood illustrates this. A piece of cedar, which is rather light, will easily float on top of water. Oak, on the other hand, is a much heavier piece that's often called a hardwood.
Waterproof hardwood flooring is natural hardwood, pine, or bamboo that has been enhanced by technology to make it impervious to liquid. The tech varies according to the manufacturer. For example, Shaw makes a product comprising a layer of real wood on top of a core of stone polymer composite (SPC).
