Why Indoor Humidity Matters More Than Most People Realise
Discover how indoor humidity affects teak furniture and learn practical ways to prevent cracking, warping, and joint movement.
Many homeowners assume teak furniture is completely maintenance-free. While teak is exceptionally stable, environmental conditions still matter—particularly indoor humidity.
Wood is hygroscopic, meaning it naturally absorbs and releases moisture from the air. During dry periods, teak can lose moisture and shrink slightly. During humid periods, it expands.
This movement is normal, but extreme fluctuations can create issues such as:
- Minor surface cracks
- Joint movement
- Slight plank separation
- Uneven doors or drawers
Air conditioning can also contribute to dryness, especially when furniture is positioned directly under vents.
The solution is not complicated:
- Maintain indoor humidity around 40–60%
- Avoid placing furniture beside heat sources
- Keep furniture out of prolonged direct sunlight
- Use humidifiers in excessively dry environments if needed
Understanding these natural behaviors helps homeowners distinguish between normal timber movement and actual defects.
