Glass however is extremely durable and requires no maintenance. When it is manufactured cleanly without any air or other materials intruding during production, it can withstand rain and ice for hundreds of years. I do not see this wood being able to achieve the same durability without intensive care and repainting which will probably cancel out the ecological effects quite soon.
