Choosing materials for a tropical climate

A material sample looks the same in every showroom. Ten years later it can look very different depending on the climate it lives in. In the Philippines, high humidity, strong sun and seasonal rain are the conditions every surface has to cope with.

Moisture is the main test

Humidity affects timber, boards and finishes more than heat does. Solid timber needs proper seasoning and sealing, and engineered products should be rated for humid conditions. In wet areas, porcelain tiles, sealed stone and properly detailed waterproofing are more forgiving than surfaces that absorb water.

Let the building breathe

Materials last longer in rooms that are ventilated. Mould usually appears where air is still. Cross-ventilation, roof overhangs and shaded openings protect interiors as much as any coating.

Choose finishes that age well

• Matte and textured surfaces hide wear better than high gloss
• Lime and mineral plasters tolerate movement and can be repaired
• Natural stone develops a patina rather than simply looking worn
• Fewer materials, used consistently, make a space feel calmer and are easier to maintain

The aim is not to avoid change but to choose materials whose change looks intentional.
