Polycarbonate sheeting has an extremely high impact strength and is stable over a greater temperature range than polymethyl acrylates like Plexiglas. Polycarbonate is very transparent to visible light - better than many types of glass in fact. It’s a much better thermal insulator than glass too. Polycarbonate is used for custom-made signage, architectural glazing and similar purposes. Different version can have different properties - for example an increased scratch resistance, higher acoustic insulation or a higher UV resistance to overcome weathering.
