Primary weather factors are responsible for most of the damage done to any material or product exposed outdoors. Sunlight, heat, and water are acting together synergistically, causing microscopic ageing, visible degradation, and product failure.
Solar radiation includes UV, visible and IR parts, each impacting materials surfaces. High temperature drives degradation, temperature cycling adds mechanical stress which may form cracks. Finally, gaseous (humidity) and liquid water can have synergistic effects on weather ageing.
