What is a Chimney Register Plate and Why do You Need One?

When installing a log burner into a fireplace, two things need to happen with regards to the existing brick chimney above. Firstly, it needs lining (please see ‘Do I Need a Flexible Chimney Liner? Spoiler alert, yes you do) and secondly, it needs sealing off. That is the job of the Register Plate.

Chimney Register Plates (or Closure Plates as they are also known), are typically a sheet of thin metal – although they can be made from any non-combustible material – designed to be fitted above the stove at the base of the chimney opening. This serves three purposes:

  1. As heat rises off the stove, it will reflect off the Register Plate and back into the room, rather than being lost up the chimney.
  2. Prevents debris, soot, wildlife or insulating materials from falling into your living space.
  3. Hides from view the unsightly adapter and flexible flue liner.

Easy to cut to size and simple to install, our Register Plates come supplied with 4 angled brackets which secure to the inside of the chimney walls, you then simply offer the plate up to the brackets and secure with screws. Finish off with a bead of heat resistant silicone or cement around the edges of the plate.
