Greenhouse glazing materials question

20 years ago

Does anyone know where I can find an unbiased comparison of the various corrugated plastics: fiberglas, PVC, and polycarbonate? Home Depot doesn't sell fiberglas anymore. They've got PVC and polycarbonate.

The fiberglas on my greenhouse roof has yellowed. Should I replace it, or can it be restored somehow?

I am also posting this on the greenhouse forum.
