When looking for cost effective choices, the option of product is crucial.
Glass: Standard 4mm float glass is durable and scratch-resistant. However, it is much heavier and needs a more significant framing system, which increases the expense.Acrylic (Perspex): Acrylic is significantly lighter and has better thermal insulating properties than glass of the exact same density. It is likewise more impact-resistant. The drawback is that it can scratch more quickly and may need specific cleansing products to prevent "clouding" over time.Polycarbonate: Often used for security, polycarbonate is practically unbreakable.
