The thickness of an acrylic mirror sheet can vary, depending on the size, desired durability, and the type of application you are using it for.
Generally speaking, acrylic mirror sheets are available in different thicknesses ranging from 0.5mm-6mm thick. The thickness of the sheet will also impact the overall price, with thicker sheets being more expensive than thinner ones.
Additionally, thicker sheets may require additional framing or support for larger or heavier installations that may add to the overall project cost.
