What type of gypsum board is used on a curved wall?

For constructing curved walls, the flexibility of the gypsum board is crucial. The ideal choice is a flexible board, commonly referred to as flexboard, which is specifically designed to bend and conform to curved surfaces without cracking.

The dimensions, particularly the thickness of 1/4 inch, allow for a greater degree of flexibility compared to thicker boards. In this context, the choice of 4 x 8 dimensions provides a balance between manageability during installation and sufficient coverage for the wall area. While 4 x 10 and 4 x 12 boards may also be flexible, their longer lengths may be more challenging to handle or fit into tighter spaces, especially given the unique requirements of a curved wall.

Thus, the selection of a 4 x 8 x 1/4 Flexboard ensures that the material can easily accommodate the curvature while remaining lightweight and easy to work with, making it the most suitable option for this application.
