Wood in the kitchen: which species can handle the Caribbean climate?

Wood in the kitchen is beautiful. Wood in the Curaçaose kitchen is a choice you must make carefully — otherwise it warps, cups or (in the worst case) splits. Here's what we've learned in 12 years of practice about which species and which constructions actually survive.

First: what does our climate do to wood?

On Curaçao relative humidity hovers between 70% and 85% year-round[^1]. Wood moves — expanding in humid spells, shrinking in dry ones. An untreated piece of solid oak can change 3–5 mm in width over a year[^2]. For a kitchen front that means cracks at the joints, drawers that no longer close, and long-term discolouration.

The answer isn't "choose the best species" — that one magical wood doesn't exist. The answer lies in construction + treatment + climate class.

What is a climate class and why does it matter?

The European standard DIN 68861 rates furniture for durability of use, and EN 14322 does the same for laminate fronts. Schüller and Nobilia test their kitchens against "Climate Class 3" — broadly meaning "resistant to varying humidity loads up to 85% RH at 23°C"[^3]. This is exactly what you need on Curaçao.

At every purchase, explicitly ask for the climate class on the product spec. Both German brands we carry meet it as standard. Cheaper Italian or Asian brands often don't.

Rankings per wood species (based on our own practice)

🟢 Good in Caribbean climate:
- Oak (Quercus robur, Quercus alba) — dense structure, low absorption. Our number 1 for warm-wood looks.
- Walnut (Juglans regia) — slightly denser than oak, darker. Great if you want a warmer feel.
- Iroko (Milicia excelsa) — tropical species, often used on the island. Ask for FSC-certified because some forests are over-exploited.

🟡 With the right treatment:
- Ash (Fraxinus excelsior) — dense structure but absorbs moisture, needs solid finishing
- Black walnut (Juglans nigra) — similar to walnut but softer

🔴 Better avoided:
- Beech (Fagus sylvatica) — absorbs moisture 40% faster than oak
- Pine and spruce — soft, softwood, warps easily
- Birch — sensitive to mould in damp corners

Solid vs veneer — a misunderstanding

Many people assume "solid = better". Not automatically. A veneer layer on a dimensionally stable core (HDF or MDF) can be more stable in humid climates than solid wood, because the core doesn't move. Schüller's and Nobilia's premium series specifically use oak veneer over a stable core for exactly this reason.

Solid is ideal for: worktops (where you really want the mass), island side panels.
Veneer is ideal for: cabinet and drawer fronts — where dimensional stability matters more than "authenticity".

FSC or PEFC — why that label matters

Both certifications guarantee responsible forestry. Extra important for Curaçao because many woods that look "tropical" may come from illegally harvested forests. Schüller publishes the FSC label per item[^4]; Nobilia works with PEFC. Either is enough for anyone who takes sustainability seriously.

Practical tip: store the wood 48 hours indoors before installation

We do this on every island installation. Fresh fronts from the container are first stored for 2 days in the final room, so the wood acclimatises to the climate before assembly. The difference between "perfect fit" and "door no longer closes" is exactly these 48 hours.

Finish: oil, lacquer, or UV-resistant varnish?

• Oil (like Schüller's natural-oil finish): beautiful, matte, feels natural — but needs annual touch-up in Caribbean climate. For enthusiasts.
• Lacquer (water-based): standard, easy maintenance, fine for 95% of use cases.
• UV-resistant varnish: for direct sun exposure (east or south windows) we recommend this. Prevents discolouration.
