Polycarbonate Sheets, Acrylic Sheets, Impact Resistant, Corrugated, Twinwall Plastic Sheets
Polycarbonate and acrylic are both stronger than glass. Acrylic has 10 times the impact resistance of glass, but polycarbonate has 250 times the impact resistance of glass. Acrylic has a high gloss finish and is more transparent than polycarbonate. The difference is negligible at first, but the gap will widen as polycarbonate will yellow, as a result of sun-exposure. Over time both will lose visual clarity, the difference being that acrylic can be polished to regain it and polycarbonate cannot be. For the purpose of growing in a greenhouse, polycarbonate may be the better choice because it is much more resilient. But for aesthetics, such as a home-attached structure, acrylic may be a better choice if you want a something stronger than glass.
