ETS-Lindgren offers two types of RF Shielded Floors; Monolithic and Modular. Monolithic flooring is ideal for installations in moist, damp environments while modular flooring is a good choice when quick installation is necessary. Our in-place Monolithic floor consists of structurally bonded materials that include a copper RF attenuator, dielectric material, and a moisture resistant barrier. Modular RF flooring uses a copper-clad wood core. A mechanical non-ferrous clamping system joins the panels together.
