&gt; Show me 100 year old (or 200 year old!) reclaimed plywood and you&#x27;ll have made me a convert.<p>You can buy 200 year old teak.  There are plenty of wooden buildings around the world that are multiple hundreds of years old.<p>When plywood is shown to last 500 years without breaking a sweat, then I&#x27;ll believe it&#x27;s a great building material full stop.<p>For $500mm it should be built to last a millenia.  I know it&#x27;s not, but again, engineer brain.
