Abstract
A method and apparatus for creating an insulated barrier within a fireplace is described. A compressible insulator may be placed in a fireplace. Within the fireplace, the compressible insulator may be placed above a lintel on the inside of a firebox opening. The compressible insulator may also be placed below a damper. The compressible insulator may be used to insulate a fireplace and increase the temperature differential between the living space and air trapped between the compressible insulator and the damper. The trapped air may also increase the temperature differential between the living space and the chimney above the damper.
Description
- The present invention is generally related to energy conservation and insulation. More particularly, the present invention relates to a method and apparatus for creating an insulated barrier within a fireplace.
- Fireplaces are commonly found in homes, offices, and many other types of buildings. Fireplaces are architectural structures that are capable of containing a fire for heating a room or other area within a building. A fireplace includes a firebox and the firebox typically contains the fire and any material that is used to create the fire. The firebox is typically found on the interior of the building that contains the fireplace. A fireplace also typically includes a chimney or other flue that allows gas and other exhaust to escape the fireplace. The chimney or flue typically extends to the exterior of the building that contains the fireplace to allow the gas and other exhaust to escape to the outside of the building.
- A fireplace also usually includes a damper. A damper is a valve or plate that stops or regulates the flow of air inside the fireplace. The damper may be used in the chimney of the fireplace to close off the chimney. The damper may also be partly closed to control the rate of combustion when a fire is occurring in the firebox. However, the damper is not designed to act as an insulator. The fireplace is directly connected to the exterior of the building, so naturally occurring drafts entering or exiting through the fireplace may allow conditioned air to escape through the chimney or may allow outside air to enter the room that contains the fireplace. Because the damper is not designed to act as an insulator and because no other features of a typical fireplace are designed to act as an insulator, there is a need for providing an insulator in a fireplace to prevent the naturally occurring drafts in a fireplace. There is also a need to create a greater temperature differential between the chimney or flue and the living space.
- A method and apparatus for creating an insulated barrier within a fireplace are described. A compressible insulator may be placed in a fireplace. Within the fireplace, the compressible insulator may be placed above a lintel on the inside of a firebox opening. The compressible insulator may also be placed below a damper. The compressible insulator may be used to insulate a fireplace and increase the temperature differential between the living space and air trapped between the compressible insulator and the damper. The trapped air may also increase the temperature differential between the living space and the chimney.
- A more detailed understanding may be had from the following description, given by way of example in conjunction with the accompanying drawings wherein:
-
FIG. 1 shows an example of a fireplace structure; -
FIG. 2 shows an example cross-section view of a compressible insulator; -
FIG. 3 shows another view of a compressible insulator; -
FIG. 4 is a flowchart of an example method of installing a compressible insulator; -
FIG. 5 shows an alternate view of a fireplace structure; -
FIG. 6 shows an overhead view of a fireplace structure; and -
FIG. 7 shows an example of a compressible insulator. - The present invention will now be described with reference to the drawings. The fireplace insulator described herein may be placed in a fireplace. The fireplace insulator may be a compressible insulator. The compressible insulator may insulate the fireplace and increase the temperature differential between the living space and the air trapped between the compressible insulator and a damper. The trapped air also creates a secondary layer of insulation to further increase the temperature differential between the living space and the chimney.

FIG. 1 shows an example of afireplace structure 100. Thefireplace structure 100 includes achimney 104, adamper 106, alintel 108, acompressible insulator 110, asmoke chamber 112, afirebox 114, a firebox opening 116, and ahearth 118. One skilled in the art will appreciate that other features, not shown, may be included thefireplace structure 100. However, these features are not shown inFIG. 1 for clarity. - In a
typical fireplace structure 100 without acompressible insulator 110, air may escape from or enter through thechimney 104. Placing thecompressible insulator 110 in thefireplace structure 100 may provide a variety of advantages, as will be explained in detail below. Thecompressible insulator 110 may be placed above thelintel 108 on the inside of the firebox opening 116. Thelintel 108 may be a steel lintel. Thecompressible insulator 110 may also be placed below thedamper 106. Thedamper 106 may be in a closed position when thecompressible insulator 110 is placed below thedamper 106. Thecompressible insulator 110 may create an insulated barrier within thefireplace structure 100. The insulated barrier provided by thecompressible insulator 110 may increase the temperature differential between the living space in a room and the air trapped between thecompressible insulator 110 and thedamper 106. Further, the air trapped between thecompressible insulator 110 and thedamper 106 may also serve as an additional layer of insulation between the living space in a room and thechimney 104 or an exterior space. Thus, thecompressible insulator 110 may increase the temperature differential between the living space in a room and thechimney 104 or area outside of thechimney 104. The temperature differential may be a result of both the insulation within thecompressible insulator 110 as well as the insulation provided by the air trapped between thecompressible insulator 110 and thedamper 106. Accordingly, an advantage of thecompressible insulator 110 described herein is two layers of insulation resulting from adding a single layer to thefireplace structure 100. - The
compressible insulator 110, upon being installed, may provide sufficient lateral force against the sides of the interior of the firebox opening 116 to remain in place without any additional force or structures. Additionally, thecompressible insulator 110 may seal off any gaps or imperfections within thefirebox 114. Thecompressible insulator 110 may remain in any fixed position without the use of additional supports or adhesives. Thecompressible insulator 110 may be in the fixed position anywhere within thefireplace structure 100. The positioning and ability to remain fixed may be due to the structure, size, shape, and/or dimensions of thecompressible insulator 110. - The
compressible insulator 110 may also limit the amount of air drawn up and towards thechimney 104. In atypical fireplace structure 100, air may be drawn up and towards thechimney 104 due to a naturally occurring draft inherent in the design of thechimney 104. A downdraft may also be created based on differential pressures between the room in which thefireplace structure 100 is located and the outside climate. The inclusion of thecompressible insulator 110 into thefireplace structure 100 may prevent the loss of air from within the room in which thefireplace structure 100 is located. The air within the room may be conditioned to a particular temperature, so retaining the conditioned air may be an additional advantage of using thecompressible insulator 110. Further, retaining the conditioned air may increase the overall energy efficiency of the room or the building in which thefireplace structure 100 is located. - As explained above, the installed
compressible insulator 110 may create a seal within thefirebox 114. The installedcompressible insulator 110 may not be visible from a viewing angle looking directly at thefireplace structure 100 from within the room in which thefireplace structure 100 is located. Thus, thecompressible insulator 110 may also provide the additional advantage of aesthetic appeal. -

Thecompressible insulator 110 may include atop sheet 204, acore layer 206, rivets 208,ribbons 210, handles 212, and/or abottom sheet 214. Thecompressible insulator 110 may also include other features that are not shown inFIG. 2 . Thetop sheet 204 may be positioned such that it faces the upper portion of thefireplace structure 100 and thechimney 104. Thetop sheet 204 may be any length or width. For example, thetop sheet 204 may be between 3 mm and 10 mm thick. Thetop sheet 204 may be laminated to thecore layer 206. Thetop sheet 204 may be composed of, for example, polyethylene or polyurethane. One skilled in the art will appreciate that thetop sheet 204 may comprise any material capable of producing the desired properties described herein. - The
core layer 206 may comprise compressible material. The core layer may be any length or width. For example, thecore layer 206 may have a total thickness between 1 inch and 3 inches. The compressible material used for thecore layer 206 may be, for example, polyethylene, polyethylene foam, polyurethane, or other materials with similar properties.
