For ICT systems, what minimum grade of plywood should be used facing the interior of the building?

The recommended minimum grade of plywood for facing the interior of a building in ICT (Information and Communications Technology) systems is A/grade. This grade is specified due to its higher quality and suitability for interior finishes where aesthetics, durability, and moisture resistance are important. Using A/grade plywood ensures a smooth and clean finish, which is essential when integrating ICT equipment and systems that may be sensitive to environmental conditions.

A/grade plywood has fewer imperfections and a more attractive appearance, making it ideal for visible installations. This grade also offers better resistance to warping and provides a stable surface for mounting equipment or racks. In contrast, lower grades like B, C, or D may have knots, inconsistencies, and exposed voids, which may compromise the overall integrity and appearance of the installation. Therefore, A/grade plywood is the most suitable choice for ensuring both functionality and aesthetics in ICT systems.
