How long does a geodesic dome last?
The galvanized steel frame can last over 50 years. The PVC membrane typically requires replacement every 10 to 15 years depending on UV exposure.
Data Insight: A materials science review in 2022 (Journal of Industrial Textiles) confirmed architectural PVC membranes retain 85% tensile strength after 10 years of moderate UV exposure.
