The question comes up often enough that it’s worth addressing directly. Someone is considering a solid hardwood dining table or a set of outdoor garden furniture, and the concern is termites. Malaysian homes are not strangers to the subterranean termite. It’s a legitimate consideration — and the answer, when the right species is chosen, is more reassuring than most people expect.

At Johor Wood Furniture, we work exclusively with hardwood species, and several of the species we use most frequently carry strong natural resistance to termite and insect attack as part of their inherent material properties. This isn’t a treatment applied after milling — it’s built into the wood itself, developed over decades of the tree’s growth. Understanding why these species resist termites helps explain why they’re worth specifying.
Why Some Woods Resist Termites Naturally
Wood durability against biological attack — including termites, fungal decay, and insects — is primarily a function of extractive content. Extractives are natural chemical compounds deposited in the heartwood of the tree as it matures: resins, tannins, oils, and phenolic compounds that are toxic or repellent to organisms that would otherwise consume the wood. Dense, slow-growing tropical hardwoods tend to have higher extractive content than fast-growing plantation timbers, which is one of the key reasons they command premium pricing.
The Malaysian Timber Industry Board classifies timber durability in five classes, from Class 1 (very durable, heartwood resistant to all forms of attack) through Class 5 (not durable). For furniture and outdoor use in Malaysia, you want Class 1 or Class 2. Anything below that in a termite-active environment is a risk you don’t need to take.
Chengal: The Gold Standard
Chengal (Neobalanocarpus heimii) is rated Class 1 for durability. It is one of the most naturally resistant hardwoods available in Malaysia, with a high resin and extractive content that makes it genuinely repellent to subterranean termites, dry wood termites, and wood-boring beetles. This is the species we recommend without reservation for anyone concerned about long-term durability — whether for interior furniture that may sit in a high-humidity ground-floor space, or for outdoor pieces in direct contact with the surrounding environment.
Chengal’s density (typically 830–980 kg/m³ air dry) also means it’s physically difficult for insects to penetrate even when the chemical resistance is not in play. The combination of extractive content and density makes it one of the most comprehensively insect-resistant timbers available to Malaysian buyers. It commands a price premium for exactly these reasons.
Balau: Comparable Performance, Slightly More Accessible
Balau (Shorea spp.) covers several species within the heavy hardwood group and generally rates Class 1 to Class 2 for durability depending on the specific species. It shares with chengal the high density and extractive content that makes it resistant to termite attack under normal conditions. Balau is the species we use most frequently for outdoor decking, pergola structures, and garden furniture — applications where long-term exposure to termite-active soil environments is a real factor.
In interior furniture applications, balau is an equally reliable choice. It won’t be chemically treated before it reaches your home — its durability is entirely natural — and it doesn’t off-gas anything in the process. That’s a consideration that matters to some buyers, particularly for furniture in children’s rooms or enclosed living spaces.
Merbau: Durable, with Caveats
Merbau (Intsia palembanica) also rates Class 1 to Class 2 and is widely used in flooring and outdoor joinery across Southeast Asia precisely because of its natural durability against insects and decay. One practical note: merbau heartwood contains water-soluble extractives that will leach reddish-brown staining in rain or with surface moisture, particularly when freshly machined. This is not a structural issue — it’s an aesthetic one, and it reduces significantly after the first season. If you’re planning merbau outdoor furniture adjacent to paving, plan for initial staining and manage with a good surface rinse-down after installation.
What About Suar?
Suar (Samanea saman) is somewhat lower in durability class than chengal or balau — it typically rates Class 2 to Class 3. For interior furniture where direct termite exposure is minimal, suar is absolutely appropriate. Its extraordinary visual character — the wide, flowing grain, dramatic figure, and natural voids — makes it a popular choice for statement dining tables and feature pieces. For ground-contact or fully exposed outdoor applications in high-risk areas, we’d advise chengal or balau instead.
Practical Risk Reduction
Even with Class 1 species, sensible installation practices reduce termite risk further. Keep furniture legs off direct soil contact where possible. Ensure adequate ventilation beneath outdoor pieces. Don’t allow mulch or organic debris to accumulate in direct contact with furniture bases. For high-risk properties — particularly older houses with known termite activity — annual inspection remains worthwhile regardless of the timber species in use.
The combination of the right species and sensible housekeeping effectively eliminates termite damage as a realistic concern for hardwood furniture in Malaysian homes. The failure cases we’ve seen — and they are not common — almost always involve untreated softwood, engineered wood, or furniture left in direct contact with contaminated soil. Properly specified hardwood furniture from reputable species does not typically fail this way.

Frequently Asked Questions
How do I get started with a custom order?
The easiest way is to message us on WhatsApp at +60 16-717 9573 with your requirements, reference photos if you have them, and your approximate budget. We will respond promptly with an indicative quote and arrange a consultation if needed.
How long does custom furniture take in Johor Bahru?
Most custom pieces take between two and six weeks depending on the size, the wood selected and how detailed the design is. Simple items such as a coffee table can be quicker, while large dining sets, built-in wardrobes or pieces requiring special timber may take longer. We confirm an estimated timeline as part of your quotation.
Do you deliver outside Johor Bahru?
Yes. While our workshop is in Masai, Johor Bahru, we deliver completed furniture throughout Malaysia and to Singapore. Delivery arrangements and any associated costs are confirmed when you place your order.
Which wood is best for outdoor furniture in Malaysia?
Chengal and Balau are the top choices for outdoor furniture in Malaysia thanks to their density and natural resistance to moisture, rot and insects. Chengal is the most durable and premium option, while Balau offers excellent weather resistance at a slightly lower cost.
