Grilles

Floor Grilles

Supply and return for underfloor systems.

Floor grilles are installed in the floor to deliver conditioned air or serve as return air intakes.

Floor grilles must be robust enough to withstand foot traffic — they are typically manufactured from heavy-duty extruded aluminium or steel with a load rating appropriate for pedestrian or light vehicular use. Bar spacing is engineered to prevent heel or shoe tip entrapment while maintaining adequate free area for airflow.

A volume control damper can be incorporated beneath the grille to allow individual outlet balancing, a useful feature in large open-plan office environments where local comfort adjustment is required.

Applications

Floor supply at glazed perimeters counteracts cold drafts in winter.
