How do balcony floors made of rubber granulate behave in different weather conditions?

Rubber granulate balcony flooring is specifically designed for outdoor use and is highly weather-resistant. Durable, adaptable, and long-lasting, it maintains its functionality and appearance even under extreme weather conditions. Below is a detailed overview of how rubber granulate balcony flooring performs under various weather conditions.

1. Rain and Moisture

Water Permeability:

• Allows rainwater to pass through the material, draining effectively via an underlying drainage layer or balcony outlet.
  Advantages:
  • Prevents puddle formation, reducing slip hazards.
  • Dries quickly after rain.
  • Prevents water stagnation, which could promote mold or algae growth.

Moisture Resistance:

• Does not absorb moisture, remaining structurally stable and functional even with prolonged water exposure.
• No risk of swelling, deformation, or loss of stability.

2. Sunlight and Heat

UV Resistance:

• High-quality rubber granulate flooring, especially with EPDM coating, is UV-resistant.
  Advantages:
  • Colors remain vibrant even under intense sunlight.
  • Material does not become brittle and retains its elasticity.

Heat Resistance:

• Can withstand temperatures up to 80°C without damage.
  Comfort:
  • Warms in the sun but remains more comfortable for bare feet compared to concrete or tiles.

3. Frost and Cold

Frost Resistance:

• Remains flexible and stable even in freezing temperatures.
  Advantages:
  • No cracks or damage from frost since the material doesn’t retain moisture.
  • Provides secure footing even on icy surfaces.

Snow Management:

• Clearing snow: Easily removed with a plastic shovel or broom. Avoid salt, which can degrade the surface over time.
• Meltwater drainage: Permeable flooring effectively drains meltwater, preventing icy patches.

4. Wind and Storms

• The heavy weight of the tiles ensures stability against strong winds.
• For high-wind areas, tiles can be glued or secured with interlocking systems for added stability.

5. Temperature Fluctuations

• Highly temperature-stable, handling extreme swings between heat and cold without issue.
• Thermal expansion: Expands slightly in heat and contracts in cold, without cracking or permanent deformation.

6. Dirt and Algae Growth

Dirt Resistance:

• Resists dirt, and light debris is often washed away by rain.

Algae and Moss Growth:

• Rare, as the material does not retain moisture. However, slight growth may occur in shaded, damp areas.
• Maintenance: Regular sweeping or rinsing with water and eco-friendly cleaners keeps the surface clean.

7. Substrate Protection

• Protects the underlying surface from weather effects such as moisture and temperature fluctuations.
  Advantages:
  • Prevents frost damage to concrete or screed.
  • Reduces erosion from rainwater.

8. Comparison to Other Flooring Materials

Tiles:

• Prone to cracking in frost and slipperier when wet.
• Grout lines require more intensive cleaning.

Wood:

• Needs regular maintenance (oiling, sealing) to prevent moisture and UV damage.
• Rubber granulate is far more durable and low-maintenance.

Concrete or Stone:

• Can crack in frost and become uncomfortably hot in direct sunlight.
• Rubber granulate remains elastic and pleasant to walk on.

9. Lifespan and Long-Term Performance

• Typically lasts 10–15 years, even under heavy use and varying weather conditions.
• Colors and material structure remain stable over time without the need for regular treatments.

Conclusion

Rubber granulate balcony flooring is an excellent choice for withstanding diverse weather conditions. It is water-permeable, UV-resistant, frost-proof, and temperature-stable, making it a long-lasting and low-maintenance solution for outdoor spaces. Whether exposed to rain, intense sunlight, snow, or frost, this flooring remains functional and safe. Compared to materials like tiles, wood, or concrete, it offers superior comfort, safety, and ease of maintenance.
