What Is Teak Wood?
Teak (Tectona grandis) is a large deciduous hardwood native to South and Southeast Asia, found naturally across Myanmar, Thailand, Laos, and India. For centuries, it has been prized by shipbuilders, furniture makers, and architects for its exceptional combination of strength, natural beauty, and weather resistance.
Today, teak is grown on managed plantations across Indonesia, India, and Central America, making it more accessible — though old-growth Burmese teak remains in a class of its own.
Key Characteristics of Teak
- Janka Hardness: ~1,070 lbf — hard enough for heavy use, workable enough for fine detailing
- Natural Oils: High silica and oil content make teak naturally water-resistant and resistant to rot, insects, and warping
- Color: Golden to medium brown when freshly cut; weathers to a silver-grey patina if left untreated outdoors
- Grain: Straight to slightly wavy, with a coarse, uneven texture
- Weight: Moderately heavy — approximately 630–720 kg/m³ when dried
Common Uses of Teak
Teak's versatility is one of its greatest strengths. Here's where you'll most often find it in use:
- Outdoor Furniture: Teak's oil content makes it ideal for garden furniture, decking, and benches without the need for constant maintenance.
- Marine Applications: Boat decking and yacht interiors have relied on teak for centuries due to its anti-slip texture when wet and its resistance to saltwater.
- Indoor Furniture: Fine dining tables, cabinets, and flooring benefit from teak's warm tones and durability.
- Construction: Doors, window frames, and structural elements in tropical climates where moisture and insects are constant threats.
- Carving: Teak is workable enough for decorative carving, widely used in Balinese and Javanese craft traditions.
Plantation Teak vs. Old-Growth Teak
| Property | Plantation Teak | Old-Growth Teak |
|---|---|---|
| Age at harvest | 20–40 years | 80–200+ years |
| Oil content | Lower | Higher |
| Durability | Good | Excellent |
| Cost | Moderate | Very High |
| Availability | Widely available | Scarce / regulated |
For most applications, responsibly sourced plantation teak performs excellently and is the ethical choice. Old-growth teak from Myanmar is subject to strict export controls and should only be purchased from verified legal sources.
Working with Teak
Teak's silica content can dull cutting tools faster than many other hardwoods. Use carbide-tipped blades and tools where possible. The natural oils can also inhibit adhesive bonding — always clean surfaces with mineral spirits or acetone before gluing. Teak finishes beautifully with teak oil, Danish oil, or can be left to weather naturally outdoors.
Sourcing Responsibly
When purchasing teak, look for FSC (Forest Stewardship Council) certification or verified plantation origin. Indonesian and Indian plantation teak are widely available through reputable timber yards. Avoid products that cannot confirm their chain of custody, particularly for items claiming to be "Burmese" or "Myanmar" teak.
