Thicker options provide more durability and are suitable for heavy-duty applications, whereas thinner backers are ideal for lightweight projects. Available thicknesses range from .020" in the Polybak PB69 to .035" in the Polybak Ultra Veneer Backer, offering diverse options to fit various project requirements.
