What type of plywood is recommended for telecommunications rooms (TRs) on at least two walls?

The recommended type of plywood for telecommunications rooms (TRs) on at least two walls is fire retardant plywood with a thickness of 19mm (3/4"). This choice aligns with industry standards that prioritize fire safety, especially in environments where electrical and telecommunication equipment may be present. Fire retardant plywood is specially treated to inhibit ignition and slow the spread of fire, which is crucial for maintaining safety and compliance in facilities that house sensitive electronics and wiring.

Using fire retardant materials in telecommunications rooms helps protect not only the physical structure but also the critical systems that support network services. As telecommunications equipment can generate heat and may be susceptible to electrical faults, having walls made from fire retardant materials mitigates potential fire hazards.

Other options may not provide the necessary level of fire resistance, which is vital for areas that house a significant amount of cabling and electronic devices. Thus, selecting the appropriate plywood type plays a pivotal role in ensuring safety and compliance with building codes relevant to telecommunications environments.
