What thickness is recommended for A-C-rated fire-retardant plywood backboards installed in telecommunications rooms?

The recommended thickness for A-C-rated fire-retardant plywood backboards installed in telecommunications rooms is 19 mm (3/4 in). This thickness provides an optimal balance between robustness and weight, ensuring that the backboard can support the necessary telecommunications equipment while maintaining fire-retardant properties.

Backboards that are too thin may not provide adequate support for equipment, which can lead to failure over time. Conversely, backboards that are excessively thick may add unnecessary weight and complicate installation without providing additional performance benefits. The 19 mm thickness is compliant with industry standards, ensuring both safety and functionality in telecommunications environments. Using this thickness contributes to effective cable management and supports the overall integrity of the telecommunications setup.
