The high-spec modular structure is traditionally used for high performance shielding. Panels are galvanized sheet steel bonded to a wood core that are attached via framing joints. The RF panel system is typically self-supported via Unistrut so no attachment to a parent wall or to a slab above is required.

A function of RF construction is to create a noise free environment to retain RF signals inside of the shielded environment. To complete the RF shielded environment, all accessories and facilities associated with the enclosure will meet or exceed the minimum functional requirements (as listed below). This includes but is not limited to the entire six-sided RF enclosure, the RF door, waveguides for HVAC and/or piping, and RF filters for electrical.
