About MEDIGUARD Plain
A plain 15mm tile for clinical areas with strict cleaning regimes: it resists disinfectants, repels water and has been tested against a range of hospital pathogens. Absorption is low, so it suits theatres, isolation rooms and labs rather than spaces needing acoustic treatment.
