Choosing the right plaster size

To choose the right plasterboard size, consider the specific requirements of your construction project. Assess the intended use, structural needs and the dimensions of the walls or ceilings where the plasterboard will be installed.

The thing is:

Thicker boards may offer enhanced fire resistance and acoustic properties, while standard thickness boards are suitable for most applications.

What’s more:

Don’t forget to verify local building codes and regulations to ensure compliance. Factor in transportation and installation logistics, as larger sheets may be more challenging to handle. To find out more about plasterboard, check out our buyer’s guide.
