Negative air pressure is an absolute requirement to prevent the spread of a respiratory disease like COVID-19. To create a negative air pressure environment, all spaces and gaps leading to the ward need to be effectively sealed in order for the air handler to develop and maintain negative air pressure in the ward. That means doors, windows, ceiling panels, and other air intrusions need to be sealed around the perimeter allowing the air to be removed from the room and processed through the proper filtration system in the hospital. To do this, Tuck Tape Sheathing Tape presents the strongest bond for uneven and varying surfaces. Tuck Tape's backing ensures a continuous and air tight barrier for improved efficiency in a medical ward environment.
