How are non-masonry siding products typically sold?

Non-masonry siding products are typically sold by the square or by the piece. This method is common in the building materials industry, particularly for products like vinyl siding, fiber cement siding, and some types of wood siding.

When sold by the square, it means that the siding is measured in increments of 100 square feet, which is a standard unit of measure for exterior materials. This approach allows contractors and homeowners to easily calculate how much material they need based on the area they wish to cover. By selling by the piece, individual panels or sections of siding can be purchased, which is beneficial for smaller projects or repairs where only a few pieces are required.

The other methods of selling siding products do exist in certain contexts, such as selling in bundles, but this is more common for roofing materials, or by weight, which is less typical for siding. Selling by the length of the strip is also less common due to the varied widths of siding products, making square footage a more effective measure for estimating needs and ensuring proper coverage.
