Choosing the right wood for outdoor furniture is crucial to ensure its durability and longevity when exposed to the elements. When selecting wood species for outdoor use, you need to consider factors like weather resistance, insect and rot resistance, maintenance requirements, cost, and aesthetics. With so many options available, it can get overwhelming to decide what wood is truly the best for outdoor furniture. This comprehensive guide will walk you through the pros and cons of various wood types to help you make an informed decision.
Weather Resistance
Outdoor furniture must be able to withstand rain, snow, intense sun, and moisture. Some wood species have natural oils, resins, and extracts that make them more resistant to water damage and the effects of weathering.
Teak
Teak is often considered the gold standard when it comes to weather resistance. This tropical hardwood has a high oil content that repels water, prevents swelling and shrinkage, and helps the wood maintain its shape and structure over time. Teak develops a beautiful silvery-grey patina when exposed to the elements. It requires no finish or treatment besides annual cleaning. Teak’s natural oils also make it resistant to mold, mildew, and bacterial growth.
Cedar
Western red cedar is another great choice for outdoor use. It has natural preservatives called thujaplicins that act as fungicides and insect repellents. The oils in cedar also help repel water. This versatility makes cedar suitable for a range of outdoor projects from patio furniture to decking. It has good dimensional stability but may shrink slightly over time. Cedar needs to be stained or sealed periodically to maintain its reddish-brown color.
Ipe
Ipe is an incredibly dense tropical hardwood that offers exceptional weather and rot resistance. It has an interlocking grain structure and high natural oil content that sheds water. Left unfinished, ipe will turn a silver-grey when exposed to the sun and rain. Scratches and dents are less visible on ipe compared to other woods. It does not require any chemical preservatives or treatment. Ipe is durable enough to last over 40 years outdoors.
Pressure-Treated Woods
Lumber like southern pine is often pressure-treated with chemicals that help protect against rot, fungi, termites, and other pests. The preservatives used give treated wood its distinctive green tint. Pressure-treated pine is an affordable option for outdoor projects. But it does require periodic sealing or staining for longevity.
Synthetic Materials
Outdoor furniture made from manmade materials like recycled plastic lumber or HDPE is impervious to moisture, rot, and pests. Synthetics will not crack, warp, or deteriorate like real wood. But they lack the beauty and character of natural wood grains. These materials can also get quite hot when exposed to direct sunlight.
Insect and Rot Resistance
Some wood species have natural properties that make them resistant to insect damage and decay caused by fungi, mold, and mildew. Woods with higher density, oil content, and extractives repel common pests like termites. Marine environments and excessive moisture necessitate the use of woods with natural rot-resistant properties.
Teak
With its high oil content and dense grain, teak is exceptionally resistant to wood-boring insects like termites. It’s also resistant to fungal attacks and rot due to its weather-resistant properties.
Cedar
Cedar contains oils that act as natural pesticides, protecting it against termites, carpenter ants, and other bugs. The aroma of cedar also helps repel moths. Its water-repellent qualities make it resistant to rot and fungal decay.
Redwood
Redwood features tannins, resins, and oils that help protect it from insect infestation and fungal growth. It has good decay resistance but may be susceptible to termites in certain environments. Proper treatment and maintenance are needed for long-term protection.
Ipe
Ipe’s extreme density and oil content make it resistant to wood-boring insects. It has exceptional natural rot resistance and does not easily mold or mildew. Ipe can last over 40 years in tough outdoor conditions with minimal upkeep.
Pressure-Treated Wood
Chemically treated lumber is protected against fungal decay and common wood pests like termites and carpenter ants. It retains its pest-resistance properties even after being cut or shaped for projects. Periodic re-application of preservatives may be needed.
Composite Lumber
Composite decking and furniture made from a mix of wood fibers, plastics, and other polymers are not susceptible to insect damage or rotting from moisture. Composite lumber contains no actual wood, so pests have no organic material to infest and destroy.
Maintenance Requirements
Outdoor furniture requires periodic cleaning, sealing, staining or refinishing based on the wood type to keep it looking its best. Some woods need more maintenance than others.
Teak
Teak needs very little maintenance besides an annual cleaning with a soft bristle brush and mild detergent. Re-oiling is not required since teak has sufficient natural oils. No finishing is needed for the first 2-3 years of outdoor exposure.
Cedar
Although naturally rot-resistant, unprotected cedar will weather to a grey color over time. Stains or sealants should be applied every 1-2 years to preserve its rich color. Smooth cedar needs more frequent reapplication than textured or knotty cedar.
Ipe
Ipe can be left unfinished indefinitely, allowing it to age naturally to a silver patina. If you prefer the rich brown color, ipe needs a UV-protectant finish reapplied annually. Smooth ipe requires more frequent maintenance than rough-sawn ipe boards.
Pressure-Treated Wood
Treated lumber is porous and prone to cracking, splintering, and cupping. It requires annual sealing or staining to protect it from moisture damage and maintain its appearance. Semi-transparent stains work better than solid color stains on treated wood.
Redwood
Though naturally decay-resistant, redwood needs periodic sealing, staining, or oiling every 1-2 years for best results. Water-repellent preservative treatments may also be applied to maintain color and smooth texture.
Composite Lumber
One of the benefits of composite lumber is its low maintenance needs. Composite furniture requires only occasional cleaning with soap and water. It does not need sealing, staining or repainting over its lifetime.
Cost
Exotic hardwoods like teak and ipe come at a premium price, while pressure-treated pine is highly affordable. Consider the total lifecycle cost and durability when investing in outdoor furniture.
Teak
As a high-end wood, teak commands premium pricing. But properly maintained teak furniture can last up to 75 years outdoors, offering excellent return on investment. Teak is a worthwhile splurge for heirloom-quality outdoor furniture.
Cedar
Western red cedar provides a good balance of affordability and weather resistance. It costs moderately more than pressure-treated pine but significantly less than exotic hardwoods. Cedar offers long-lasting performance at a reasonable price point.
Ipe
Ipe is one of the most expensive woods for exterior use due to high demand and limited supply. But its extreme density and longevity – over 40 years outdoors – help offset the steep initial cost over time. Ipe is ideal for those prioritizing durability and performance.
Pressure-Treated
Pressure-treated lumber is the most budget-friendly option for outdoor projects. Although affordable, frequent maintenance and replacement costs add up over the years. Treated wood makes sense for temporary structures rather than long-term furniture.
Redwood
Genuine redwood lies in the middle price range – more than pine but less than exotic varieties. Redwood’s natural beauty, decay resistance, and moderate pricing make it a practical choice for many homeowners.
Composite Lumber
Composite and plastic lumber have high upfront costs, though technological advances are bringing prices down over time. Their weather-resistance and low-maintenance merits make composites cost-effective in the long run.
Aesthetic Qualities
The visual appeal of the wood species influences the look and style of outdoor furniture. Certain woods exhibit distinctive grain patterns, textures, and colors.
Teak
Teak has an attractive straight, tight grain pattern ranging from pale yellow to dark golden brown. When exposed to the elements, it ages to a dignified silver-grey finish. Teak’s natural beauty and neutral weathered tone allow it to fit any style.
Cedar
Western red cedar displays a wide array of warm reddish-brown hues and swirling grain patterns. Its aromatic wood has a knotty, uneven texture. Cedar offers a rustic and traditional visual flair.
Ipe
Ipe is almost black when fresh-cut, maturing to a rich reddish-brown. It has a consistent grain and smooth texture. Ipe’s dramatic coloration and minimalist look lend a contemporary, modern style.
Redwood
Redwood has vibrant red heartwood with light sapwood in hues of pink and cream. Figures like burls and swirls create visual interest. Redwood has a refined yet outdoorsy look perfect for craftsman-style homes.
Pine
Pressure-treated pine is yellowish initially but weathers to a grey, rustic appearance. The wood grain is relatively smooth and uniform. Pine has a casual, down-to-earth look and feel.
Composite Lumber
Composite lumber comes in a diverse range of earthy tones like greys, browns, and beiges. The plastic wood grains lack natural variation. Composites have a consistent, minimalist appearance.
