How are floor and ceiling registers used?

Floor registers are part of your heating and ventilation system. They give you an important way to regulate airflow within your home. 

Here are some of the ways Imperial Floor Registers can add comfort to your home:

  • Maintain uniform temperatures from room to room
  • Direct air flow away from certain areas
  • Isolate rooms that you don’t need to heat or cool
  • Block cold air from entering the home from the basement
  • Help circulate cold air from the basement to cool the home
  • Move warm air produced by a wood stove to the upper floors

What is the difference between a register and a grille?

What is a register?

Registers are covers or grates placed in the air flow openings in your house. They give you control over volume and direction of the air entering a room. A floor register works by pressing the lever on the floor register's damper box to open shutters that direct air into the room. By pressing the lever on the floor register's damper box the other way, the shutters close reducing the flow of air.
 

 

What is a grille?

Grilles are the vents through which air is pulled out of a room for circulation back to the central heating or cooling unit. Grilles do not have the damper controls found on registers. Imperial Grilles are installed in cold air return ducts.

Characteristics of registers

  • They include a damper that provides control, to direct and diffuse the amount of air that enters a room. 
  • Registers may direct air in one, two, three or four different directions depending on the type of register.
  • They are installed on floors, walls and ceilings. 
  • If they are blocked the temperature in a room can be greatly affected. 
  • Most registers have a single valve or a multi-shutter damper.
 

Characteristics of grilles

  • They have no damper to close off the flow of air. 
  • They may be located in floors, ceilings and walls. 
  • They provide return air circulation within a room; where unobstructed flow is required for heating/cooling system efficiency. 
  • You may have several small grilles located throughout your home or one large central grille installed near the furnace.

How to replace an existing register or grille

When installing new floors, many overlook replacing existing floor registers with ones that complement their new flooring and home decor. Fortunately, this is something anyone can do themselves. 

Step-by-step

  1. Determine the size of the register.
    Remove the original vent cover to expose the ventilation opening. Measure the length and width of the opening. Subtract 1/8" to 1/4"(depending on how square the opening is) and this is the inside dimensions for the new floor registers. Reinstall old register until you get the new ones. 
  2. Select an Imperial Register.
    Imperial Registers are designed to fit the standard openings used in most homes. A wide variety of designs and finishes are available.
  3. Unpack and Install.
    Imperial Registers come fully assembled. Simply drop into place. 
 

To replace a ceiling register

Replacing a ceiling register is just like that of the floor register except for a couple of steps:

  1. After the initial size check, make sure that there is sufficient wall or ceiling space at the short ends of the wall register to allow for you to attach it to the wall with screws that are provided with your new register. 
  2. Final installation requires a screwdriver to attach the wall register to the wall or ceiling with the screws provided. 

Measure the opening… NOT the register!

How to create an new opening for a register or grille?

If you are expanding your heating and/or cooling system, we recommend you consult an HVAC technician about placement and installation. 

If you are simply adding a register, say for distributing heat from a wood stove, following these instructions should help:

What you'll need:

  • Heating duct
  • Tape measure
  • Pencil
  • Saw
  • Imperial Register or Grille
 

Step 1 - Locating and measuring

Measure the rough opening as specified on the Imperial Register or Grille packaging. Check for joists and other potential obstructions before locating the register or grille. When you’re doing this, you need to be sure that it sits square and an ample distance from the wall. Draw the shape of the opening on the existing floor.

Step 2 - Sawing

Next, saw through the subfloor and the hardwood floor in your room. If you’re putting carpet in the room, you will need to fit the floor heating vents before you install the carpet. Using a reciprocal saw, cut through the floor and cut roughly around the rectangle you’ve made where the floor heating vent will fit through the floor. You don’t have to be exact with this because the frame of the Imperial Grille will cover any irregularities. 

Step 3- Fitting the vent

An Imperial Floor Register or Vent uses its own weight to stay in place on the floor, so just insert into opening

How to deflect air where you want it

Since hot air rises, you might want to direct it to the center of a room

The Imperial Pop-Up Register is perfect for floor registers that are covered by curtains or furniture. When not covered, it works like a typical floor register. But when the curtains are closed and cover the register, simply close the register top, and pop it up to redirect the airflow to the side, for optimum heating or cooling efficiency!

Imperial Pop-Up Registers also features a 100% shut off damper that stops the airflow completely, a handy feature for total control over airflow or when airflow is not required.

The Imperial Pop-Up register is easy to clean, rust proof, scratch resistant and ideal for light humidity areas. It can be installed in both floor and ceiling application with heating and cooling systems.

The Imperial Air Deflector is also an alternative.
