The materials have an indirect and occasionally direct impact on durability, affordability, pricing, and service. If superior materials are used, the product will survive a long time; otherwise, it will not.

Wonderboard is mostly used in domestic settings, with commercial applications being less common. 

Because WonderBoard is not waterproof, it is vital not to utilize it in a business setting, as commercial settings sometimes necessitate a more cautious approach due to the huge number of persons involved.

While prices vary depending on the shop, thickness, and other considerations, a 3ft x 5ft tile of 14-inch-thick HardieBacker board costs around $12 on average.
