When specifying materials for drylining projects, plywood backing boards are often a small but essential detail.
Used within partition systems, they provide the reinforcement needed to support sanitaryware, radiators, grab rails and other wall-mounted fixtures — helping ensure long-term performance and avoiding issues post-installation.
Plywood backing boards provide structural reinforcement within metal stud partitions, allowing fixtures to be securely fixed where plasterboard alone would not be sufficient.
Installing backing boards during first fix is standard practice on many projects and helps avoid costly remedial work later.
Common thicknesses for drylining backing boards include:
Plywood backing boards are commonly used for:
In higher humidity environments such as commercial washrooms, marine plywood may be specified for improved moisture resistance.
This makes it suitable for areas exposed to moisture or frequent use, where durability is important. As always, final material selection should align with project specifications.
Rather than sourcing plywood separately, it can be added to your drylining package alongside plasterboard, metal stud and ceiling systems.
