Built for Nature’s Extremes. Designed to Last Decades.

Outdoor environments are unpredictable. Materials are tested not once, but continuously - by climate, by light, by moisture, by seasonal extremes. True performance reveals itself slowly, over years of exposure. Therefore Etna Design works with basalt fiber that was developed for precisely these conditions.

UV Stability - Enduring Colour and Structure

Prolonged exposure to ultraviolet radiation is one of the primary causes of material degradation in outdoor furniture. Many surfaces fade, weaken, or become brittle over time.

Basalt fiber offers inherent resistance to UV exposure due to its mineral composition. The material does not rely on surface treatments alone for protection. Structural stability remains intact, and colour retention is maintained even under intense sunlight. Etna Design products ensure consistency - in appearance and performance.

Resistance to Coastal Conditions

Salt-laden air accelerates corrosion in many conventional materials. Metals oxidize. Coatings deteriorate. Structural integrity can be compromised.

Basalt fiber does not rust, oxidize, or corrode. Its inorganic nature provides natural tolerance to saline environments, making it suitable for coastal architecture and open-air installations where exposure is constant and unavoidable.

Thermal Stability Across Extremes

Outdoor environments are defined by fluctuation. Summer heat. Winter frost. Sudden shifts between day and night temperatures. Our basalt fiber products demonstrate high dimensional stability across a broad temperature range. It does not warp, swell, or contract unpredictably. Structural performance remains reliable under thermal stress, preserving form and balance even in demanding climates.

Structural Strength Without Excess Weight

The continuous filament structure of basalt fiber provides high tensile strength and rigidity while maintaining relative lightness. This combination allows for sculptural forms that are structurally stable without unnecessary mass. The material supports architectural clarity - where strength is integrated into design rather than concealed behind reinforcement.

Longevity and Responsible Material Use

Durability is not only a question of performance - it is also a question of sustainability. Etna Design products are designed to last - and therefore reduce the need for replacement, repair, and resource consumption.

Basalt is a naturally occurring mineral material requiring minimal chemical additives during fiber formation. Its extended service life supports a more responsible approach to outdoor design - where longevity becomes an environmental advantage.

Designed for long-term performance across climates and decades.
