Curious if anyone has thought to use XPS foam as a cover for an above ground pool. Similar to a hot tub but not nearly as thick. Could be sectioned off to keep the weight down. Reinforce the seems with thin steel or even 1x2s. Bungee the edges down or throw a rock on top for wind. Wonder if it would insulate as well as a solar cover? It would keep a lot more debris out of the pool and would be easy to leaf blow the top off before removing it.
