What is Floor Register?


Floor registers are commonly used on wood flooring, normally there are two kinds of floor registers, one is flush mount type, the other one is self rimming type, it function as air ventilator, ventilate the air between room and outside, and adjust the air flow volume and direction. Let us know more what is floor register and how it works.


Floor register can be found throughout homes that have forced air heating and cooling systems. Floor registers are used predominantly with perimeter distribution systems and they provide good air delivery for both heating and cooling, but how it works to heat or cool your home? The answer is below.



How Does Floor Register Work?


There will be a damper box to control airflow in two ways. By pressing the lever on the floor register damper box, it will open the shutters to allow greater amount of air to stream into the room.


If your furnace is generating hot air - you will warm up the room through the damper box, and if your furnace is generating cold air - you will cool the room through the damper box. By pressing the lever on the floor register damper box the other way, you will close the shutters and thus have an opposite effect on the room airflow.


Some floor registers have a lower damper box and a grille on the top. The grille is designed to protect items from falling into the damper box and distribute the warm or cool air throughout the room. The damper box holds a louver which controls the airflow. The air delivery pattern from a floor register can range from perpendicular to fan shaped depending on louver configuration.


Two types of dampers are commonly used on registers - single-blade dampers and opposed blade dampers. The opposed-blade generally provides more uniform air flow. Registers are available in three main variations for use on floor, baseboard or wall applications.
