Nevertheless, it is heavier and requires a more considerable framing system, which increases the cost.Acrylic (Perspex): Acrylic is considerably lighter and has much better thermal insulating homes than glass of the same density. It is likewise more impact-resistant. The drawback is that it can scratch more quickly and may need particular cleaning products to prevent "clouding" in time.Polycarbonate: Often used for security, polycarbonate is essentially solid.
