Abstract
Description
- The present invention relates generally to removable panel finishing systems, and more particularly, to an acoustic partition that increases sound absorption in a removable panel finishing system for rooms such as may be found in single family homes or commercial buildings.
- Sound insulation materials are used in a variety of settings where it is desired to dampen noise from an external source. For example, sound insulation materials have been used in applications such as in appliances to reduce the sound emitted into the surrounding areas of a home, in automobiles to reduce mechanical sounds of the motor and road noise, and in office buildings to attenuate sound generated from the workplace, such as from telephone conversations or from the operation of office equipment. Acoustical insulation materials typically relies upon both sound absorption (i.e., the ability to absorb incident sound waves) and transmission loss (i.e., the ability to reflect incident sound waves) to provide adequate sound attenuation.
- Conventional acoustical insulation materials include materials such as foams, compressed fibers, fiberglass batts, felts, and nonwoven webs of fibers such as meltblown fibers. Laminates formed of one or more layers of insulation provide the desired acoustical and insulating properties and one or more additional layers of a rigid material provide desired mechanical strength properties and permit simple and convenient installation as well as proper functional performance. Such insulation materials may be used in the walls of single family homes and commercial buildings to both insulate and reduce sound emission from the rooms. Some examples of conventional acoustical materials are set forth below.
- U.S. Patent Publication No. 2004/0077247 to Schmidt et al. describes a nonwoven laminate that contains a first layer formed of thermoplastic spunbond filaments having an average denier less than about 1.8 dpf and a second layer containing thermoplastic multicomponent spunbond filaments having an average denier greater than about 2.3 dpf. The laminate has a structure such that the density of the first layer is greater than the density of the second layer and the thickness of the second layer is greater than the thickness of the first layer.
- U.S. Patent Publication No. 2004/0002274 A1 to Tilton discloses a laminate material that includes (1) a base layer formed of polyester, polypropylene, polyethylene, fiberglass, natural fibers, nylon, rayon, and blends thereof and (2) a facing layer. The base layer has a density of from approximately 0.5-15.0 pcf and the facing layer has a density of between about 10 pcf and about 100 pcf.
- U.S. Pat. No. 6,758,305 to Gelin et al. discloses a sound-deadening laminate that is formed of a structural skin and a layer of a sound-deadening material. The sound deadening material has an equivalent Young's Modulus between 50 and 600 psi. It is taught that the laminate may be attached to the framing members of a building.
- U.S. Pat. No. 6,152,259 to Freist et al. teaches a sound-deadening laminate that has a bituminous layer more than 1 mm thick bonded to one side of a thermal insulation layer such as foam or felt. An adhesive layer (e.g., cement) is positioned on the opposing side of the thermal insulation layer so that the laminate can be affixed to a component to be acoustically improved.
- U.S. Pat. No. 5,886,306 to Patel et al. discloses a layered acoustical insulating web that includes a series of cellulose fiber layers sandwiched between a layer of melt-blown or spun-bond thermoplastic fibers (e.g., polypropylene) and a layer of film, foil, paper, or spunbond thermoplastic fibers.
- U.S. Pat. No. 5,185,197 to Nixon discloses an acoustic panel that is formed of a lightweight fiberglass core with a white or light colored glass mat positioned on a first surface. The glass mat may be attached to the fiberglass core by an adhesive. A textured paint is applied to the outwardly facing surface of the glass mat to provide an aesthetically pleasing surface. It is preferred that a thin textures of colored, tiny flakes are applied to produce a mottling appearance.
- U.S. Pat. No. 4,948,660 to Rias et al. describes a heat and sound insulating panel that is formed of an outer layer of glass fibers, an insulating layer of glass fibers bound by an organic binder, and an aluminum film positioned between the outer layer and the insulating layer. The aluminum film has a thickness less than or equal to 9 microns.
- In newly constructed homes, it has become more commonplace to leave rooms unfinished and for the homeowners to finish the rooms themselves as more money becomes available or as the homeowner's family grows. Removable panel systems, such as the finishing system disclosed and described in U.S. Patent Publication No. 2004/0219853 to Weir, et al. entitled Room Finishing System, herein incorporated by reference in its entirety, provide an insulation system for a room that is easy to install and maintain. The finishing system described in Weir et al. contains a plurality of frame members attached to a masonry wall, a plurality of insulation panels, and first and second snap-in connectors to hold the insulation panels within the frame members. The second snap in connectors are releasably connected to one of the first connectors to permit easy removal of the insulation panel.
- Other examples of wall finishing systems are described below.
- U.S. Pat. No. 3,721,050 to Perina discloses a modular grid panel retention system that includes a framework attached to a masonry wall. Panels are attached to the framework by complementary hook and loop fasteners. The panels may be translucent to allow indirect lighting of a basement from behind the panels. It is taught that the grid panel retention system may be used in structures such as basements of industrial buildings and business establishments.
- U.S. Pat. No. 5,606,833 to Andersson discloses a wall structure for the interior sound and thermal insulation of rooms. The wall structure includes one-piece metal fastening profiles attached to the walls of a room or to composite insulating members to hold insulating members against the walls. The insulating members each include a soft insulating sheet fastened to a rigid support sheet. Fastening profiles fasten the insulating members by inserting them between the soft and rigid sheets and thus either attaching a particular insulating member directly to a wall or to an adjoining insulating member.
- U.S. Pat. No. 5,606,841 to Carter, Jr. discloses interior wall panels that have a rigid frame backing member to which an outer pliable sheet material is secured. A filling or padding material is retained between the sheet material and the backing member. The sheet material is secured through the filling at spaced locations to create a three dimensional surface relief. In some embodiments, the wall panels are constructed to provide thermal and insulating properties.
- Despite the numerous acoustical insulation products in existence in the art, none of the existing acoustical products provide sufficient sound attenuating properties for use in homes and commercial buildings. Thus, there remains a need in the art for insulation materials that have improved sound absorbing qualities, especially improved acoustical absorbing materials that can be utilized in a removable panel finishing system.
- It is an object of the present invention to provide an acoustical absorbing membrane or acoustic partition that may be used in removable panel finishing systems. The materials that form the acoustic membrane are not particularly limited so long as the materials possess sound-absorbing or sound-deadening qualities. Non-limiting examples of sound transmission loss materials suitable for use as the sound absorbing membrane include foil, a foil-faced asphalt material, elastomeric materials, composite laminates, a polymer film (e.g., polyethylene, nylon, and the like), a composite material formed of an organic bonding material and one or more types of reinforcement fibers, a cement board, a gypsum board, a gypsum/WUCS (wet use chopped strand glass) board, a dense WUCS mat, a film formed of a fiberglass reinforced resin, or any other dense polymeric material. The acoustic membrane may also be a film formed of a loaded polymer or copolymer such as a copolymer of ethylene-vinyl acetate (EVA) loaded with barium or CaCO3. In addition, the acoustic membrane may be rigid, flexible, or semi-flexible. The acoustic membrane may have a density of approximately 1 lb/ft2-3 lbs/ft2 and preferably has a thickness from about 1/16 of an inch—about ⅜ of an inch.
- It is also an object of the present invention to provide a removable panel finishing system that includes an acoustic membrane described herein to improve the sound absorbing properties of the finishing system. The acoustic membrane may be attached in a continuous or successive fashion around the room to be finished and may be affixed to the framing studs of the room by mechanical fasteners or adhesives. Joints between successive acoustic membranes may be sealed by tape or caulk to form a substantially continuous acoustic membrane, and therefore a continuous or nearly continuous sound barrier. A frame member formed of a base plate and two projecting arms may be attached to a stud through the acoustic membrane by mechanical fastening devices such that the arms of the frame member project away from the acoustic membrane and towards the interior of the room. Alternatively, the frame member may be affixed to the acoustic membrane by an adhesive. Insulating panels formed of an insulating core material, a fabric facer (such as a fabric or other decorative finish), and optionally a backing facer are positioned between the base plate of the frame member and retaining arms of either a corner frame member (for positioning the insulation panels in a corner of the room) or a divider member (for positioning the insulation panels along a wall of the room). The corner frame member and divider member are releasably connected to the frame member so that the insulation panels can be easily removed.
- It is a further object of the present invention to provide a removable panel finishing system that includes insulation panels having thereon an acoustic membrane described herein to improve the sound absorbing properties of the finishing system. The insulation panels may be formed of an insulating core material, an acoustic membrane, and optionally a backing facer. In one exemplary embodiment, the acoustic membrane is laminated to the insulating core by the use of an adhesive after formation of the insulating core material. Alternatively, the acoustic membrane may be adhered to the insulating core material either during fabrication by introducing the acoustic membrane to the forming section of a glass wool process or prior to curing the glass wool. The acoustic membrane may be formed of a waterproof material so that the insulation panels may be used in places where the insulation panel may be exposed to water or have a need to be cleaned, such as in a shower stall, near a bathroom sink, in a kitchen, or in a recreational room. The insulating panels are positioned between the base plate of the frame member and retaining arms of either a corner frame member (for positioning the insulation panels in a corner of the room) or a divider member (for positioning the insulation panels along a wall of the room) with the acoustic membrane facing the internal portion of the room to be finished. The corner frame member and divider member are releasably connected to the frame member so that the insulation panels can be easily removed.
- It is yet another object of the present invention to provide a drop ceiling utilizing a removable panel finishing system that includes insulation panels having thereon an acoustic membrane described herein to improve the sound absorbing qualities of the room. For example, a drop ceiling may be formed utilizing a removable panel system in conjunction with insulation panels formed of an insulating core material, an acoustic membrane, and optionally a backing facer. A framing member is mechanically and/or adhesively fixed to a sub-floor framing member such that the arms of the framing member face downwardly and into the interior of the room to be finished. The insulating panels are positioned between the base plate of the frame member and retaining arms of a divider member with the acoustic membrane facing the internal portion of the room. The divider members are releasably connected to the frame member so that the insulation panels can be easily removed.
- It is a further object of the present invention to provide a drop ceiling utilizing a removable panel finishing system described herein. In this exemplary embodiment, an acoustic membrane such as described above may be mechanically affixed to sub-floor framing members in a continuous or successive manner. Joints between successive acoustic membranes may be sealed, such as by tape or caulk, to form a substantially continuous acoustic membrane across the ceiling (and therefore form a continuous or nearly continuous sound barrier). A framing member having a base plate and two arms extending perpendicularly from the base plate may be mechanically and/or adhesively affixed to the sub-floor framing members such that the arms of the framing member face downwardly and into the interior of the room to be finished. The insulation panels are positioned between the base plate of the frame member and retaining arms of a divider member with the fabric facing facing the internal portion of the room. As with the embodiments described above, the divider member is releasably connected to the frame member so that the insulation panels can be easily removed.
- It is an advantage of the present invention that unlike conventional drywall walls, there is little or no dust generated during installation of the removable panel finishing system.
- It is another advantage of the present invention that the acoustic membrane can be easily cut, such as to fit around doors and/or windows.
- It is yet another advantage of the present invention that a removable panel finishing system utilizing the acoustic membrane absorbs approximately 75% of the sound energy within the room.
- It is a further advantage of the present invention that the acoustic membrane reduces echo time to less than about one second.
- It is also an advantage of the present invention that the acoustic membrane can be fabricated to have an aesthetically pleasing surface.
- The foregoing and other objects, features, and advantages of the invention will appear more fully hereinafter from a consideration of the detailed description that follows. It is to be expressly understood, however, that the drawings are for illustrative purposes and are not to be construed as defining the limits of the invention.

- The present invention relates, at least in part, to an acoustical absorbing membrane or acoustic partition that may be used in removable panel finishing systems. The components or materials that form the acoustic membrane are not particularly limited so long as the material(s) possess sound-absorbing or sound-deadening qualities. Non-limiting examples of sound transmission loss materials suitable for use as the sound absorbing membrane include foil (e.g., aluminum foil), a foil-faced asphalt material, rubberized asphalt, asphalt, elastomeric materials, composite laminates, a polymer film (e.g., polyethylene, polypropylene, polyethylene terephthalate (PET), ethylene vinyl acetate (EVA), and the like), or a composite material formed of an organic bonding material and one or more types of reinforcement fibers. The reinforcing fibers may be any organic or inorganic fiber that possesses good structural qualities as well as good acoustical and/or thermal properties. In addition, the acoustic material may be a cement board, a gypsum board, a gypsum/WUCS (wet use chopped strand glass) board, a dense WUCS mat, a film formed of a fiberglass reinforced resin, or any other dense polymeric material. For example, the acoustic membrane may be a film formed of a loaded polymer or copolymer (e.g. a vinyl polymer) such as a copolymer of ethylene vinyl acetate (EVA) loaded with barium or CaCO3. Other non-limiting filler materials for the polymer or copolymer include clay, iron, lead, steel, zinc, and stone. The acoustic membrane may be rigid, flexible, or semi-flexible. The acoustic membrane may have a density of from approximately 1 lb/ft2-3 lbs/ft2, and preferably has a density of from approximately 1 lb/ft2-2 lbs/ft2. In addition, the acoustic membrane may have a thickness from about 1/16—about ⅜ of an inch thick, preferably from abut ⅛—about ¼ of an inch.
- In one exemplary embodiment of the invention, the acoustic membrane is affixed to the frame of a room, such as in a residential home or commercial building. As shown in
FIG. 1 , aframe 10 includesstuds 12 that interconnect a base member 14 and atop member 16. The studs may be formed of metal, wood, or any other suitable building framing material. Mechanical fasteners (e.g., nails, screws, tacks, staples, and the like) or adhesives may be used to fasten theacoustic membrane 20 to the framingstuds 12. Theacoustic membrane 20 may be attached in a continuous or successive fashion around the room to be finished. Often, theacoustic membrane 20 is not of sufficient length to cover theframe 10 of a room in one solid piece. Thus, joints between successive acoustic membranes 20 (not shown) may be sealed, such as by tape or caulk, to form a substantially continuousacoustic membrane 20. The term “substantially continuous acoustic membrane” as used herein is meant to denote a continuous acoustic membrane or a nearly continuous acoustic membrane. - After the attachment of the
acoustic membrane 20 to thestuds 12, a removable panel finishing system may be placed on the acoustical membrane to finish the room. As used herein, the terms “finish”, “finishing”, and “finished” refer to the process of installing a removable panel finishing system to achieve a wall surface that would be acceptable for use in regularly inhabited rooms, including rooms in a residential home or a commercial building. A drop ceiling or floor treatment such as tiling, carpeting, or hardwood flooring may be installed at the same time as the removable panel finishing system, but these installations are not specifically required within the meaning of the terms “finish”, “finishing”, and “finished”. - As shown in
FIG. 2 , aframe member 22 may be attached to astud 12 through theacoustic membrane 20 by any conventional mechanical fastening devices, such as, but not limited to, nails, screws, tacks, or staples such that thearms 26 of theframe member 22 project away from theacoustic membrane 20. An adhesive may be used in addition to mechanical methods to attach theframe member 22 to awall stud 12. It is also considered within the purview of the invention to attach theframe member 22 to the acoustic membrane by an adhesive, provided that theacoustic membrane 20 is sufficiently strong to hold theframe member 22 and the remaining portions of the panel finishing system described hereafter. - A portion of an inside corner of a finished room is depicted in
FIG. 3 . In at least one exemplary embodiment of the invention, the corner of the finished room includes aframe member 22 attached to theacoustic membrane 20 and acorner frame member 30 releasably connected to framemember 22. It is to be appreciated that, inFIG. 3 , although theframe member 22 is shown as being affixed to theacoustic membrane 20 via an adhesive such as is described above, it could alternatively be affixed to astud 12 located behind thebase plate 24 of theframe member 22 by a mechanical fastening device and/or an adhesive (not shown). It should also be understood that variations in the designs offrame members 22 could occur and remain within the scope of the present invention. - As shown in
FIG. 3 , a releasable connection between theframe member 22 and thecorner frame member 30 may be achieved bycatches 28 located on thearms 26 of the frame member 22 (which form a female connector) and aconnection member 32 of the corner frame member 30 (which forms a male connector) and snaps between thecatches 28 such that thecatches 28 releasably retain theconnection member 32 therebetween. Alternatively, the releasable connection could be achieved by other arrangement of elements. For example, theframe member 22 could bear a male connector and thecorner frame member 30 could bear a female connector. Other types of snap-in connectors or fast-release connectors known to those of skill in the art may alternatively be used. - The
corner frame member 30 includes a pair of retainingarms 34. Each retainingarm 34 extends outwardly such that when the panel finishing system is assembled, at least a portion of eachrespective insulation panel 40 is located between one of the retainingarms 34 andbase plate 24. Theinsulation panel 40 may have a fabric facing ordecorative surface 44 on the side facing the room to provide an aesthetically pleasing surface and abacking member 48 on the back surface of theinsulation panel 40 to provide additional support. Thedecorative surface 44 may be colored and/or textured. The retainingarms 34 and thecorner frame member 30 thereby retain theinsulation panels 40 against thebase plate 24 and theacoustic membrane 20. It should be noted that because the retainingarms 34 each extend across a portion of arespective insulation panel 40, there is a relatively large margin of error available to an installer with respect the proper sizing of theinsulation panels 40 and the placement of theframe member 22 and thecorner frame member 30. In other words, there can be a relatively sizable gap between theend 42 of aninsulation panel 40 and, respectively, theacoustic membrane 20 orarm 26 of theframe member 22, and the finished wall will still have an attractive appearance because the gap will be hidden behind arespective retaining arm 34. This feature of the removable panel finishing system allows the installer to spend less time carefully measuring where to attach theframe member 22 or where to cut aninsulation panel 40 to fit it into an odd-sized space, with little appreciable reduction of overall thermal performance. - Turning now to
FIG. 4 , a portion of a finished room along a wall of a room where twoinsulation panels 40 abut along the same wall can be seen. As illustrated inFIG. 4 , twoinsulation panels 40 are retained against theacoustical membrane 20 by thebase plate 24 of theframe member 22 and adivider member 50 that are releasably connected. Thedivider member 50 includes two retainingarms 52 that maintain theinsulation panels 40 in positions adjacent theacoustic membrane 20 and maintain an aesthetic appearance between the twoinsulation panels 40. It is to be appreciated that inFIGS. 3 and 4 , many of the features of the releasable panel finishing system are the same regardless of the room under consideration. Thus, it should be understood that the releasable connection of thedivider member 50 andcorner frame member 30, the operation and advantages of the retainingarms - In at least one embodiment of the invention illustrated in
FIG. 5 , theinsulation panels 40 may be formed of aninsulting core material 46, abacking facer 48 on the rear surface of the insulatingcore material 46, and a fabric facing 44 on the front surface of the insulatingcore 46. Thebacking facer 48 may be a glass mat facer and may have a weight between 10 and 40 lbs per ream (2880 Ft2). As shown inFIG. 5 , thefabric facer 44 may be laminated to the insulatingcore 46 by the use of an adhesive 49 after formation of the insulatingcore 46. Preferably, the adhesive has a flame retardancy of less than 25 flame spread and 450 smoke generation (per ASTM-E85), applied at the rate of between 2 gms/ft2 and 8 gms/ft2. Alternatively, thefabric facer 44 may be adhered to the insulatingcore material 46 either during fabrication by introducing thefabric facer 44 to the forming section of a glass wool process or prior to curing the glass wool to form a board. The fabric on thefabric facer 44 can be any type of decorative covering, including natural and artificial fiber fabrics. A durable fabric is preferred so that when it is combined with theinsulting core material 46, it will pass relevant UL flame and smoke spread tests. In addition, fabric facing 44 provides aesthetics, abrasion resistance, cleanability, toughness, resiliency, rigidity, and elimination of occupant exposure to the insulating core material 46 (e.g., a fiberglass core material). - The insulating
core material 46 may be a foam or fibrous insulation board or a combination of an insulation batt and an insulation board. If a foam insulation board is used, a preferred board would be constructed from a resilient melamine foam such as a melamine foam sold under the Basotect® by BASF. If a fibrous insulation board is used, a preferred board is a 700 Series glass fiber insulation board available from Owens Corning, with a 703 Series board having a density of at least about 3 lb/ft3 being particularly preferred. Such glass fiber insulation boards are formed of glass fibers having a binder thereon which has been cured to bind the fibers into a matrix. For densities above about 2.25 lb/ft3, boards of such bindered glass fibers are relatively rigid and can generally support their own weight when stood on their end. Further, they do not sag by any significant amount when left in such a position for a long period of time. It is preferred that the insulatingcore material 46 and thus theinsulation panels 40, whether they are foam or fibrous, be relatively rigid so that thepanels 40 maintain their shape over time. It is also preferred that theinsulation panels 40 are tackable, e.g., that they are strong enough to hold the weight of a picture or other decorative hanging by means of one or more nails or tacks pushed into theinsulation panels 40. It should be understood, however, that because such boards are preferably made from a resilient melamine foam or a fibrous material, they have a generally soft, resilient surface and are relatively acoustically absorptive over a midrange of audible frequencies, e.g., a range including human speech, television programs, etc. - A
finished room 60 with the removable panel finishing system described above is shown inFIG. 6 . Thefinished room 60 includes a plurality ofdivider members 50 and corner frame members 30 (only one of which is shown inFIG. 6 ). The frame member 22 (not shown inFIG. 6 ), thedivider members 50, thecorner frame members 30, end trim members 64, and window trim members 66 are preferably composed of a polymer material (e.g., polyethylene, polypropylene, polyvinyl chloride, or polystyrene) or a metal material. A polymer material is generally preferred over a metal material to reduce the rate of heat conduction through thedivider members 50,corner frame members 30, end trim members 64, and window trim members 66. The outer surfaces of thetrim frame members 62 may be treated in a manner well-known in the art such that they possess a decorative finish, such as a simulated wood grain finish. Theroom 60 may also include afloor 68 and a ceiling 70. The ceiling 70 is shown in theFIG. 6 for convenience as a drywall ceiling, but it may alternatively be some form of a drop ceiling. Thefloor 68 is depicted inFIG. 6 as a tile floor. However, thefloor 68 may be carpeted, be a wood floor, or be otherwise covered with a suitable flooring material. In addition, theroom 60 may have windows and doors therein, such aswindow 72. - In an alternate embodiment of the invention, the
acoustic membrane 20 is pre-applied to thecore layer 46 of an insulation panel. Similar to thefabric facer 44 described above, theacoustic membrane 20 may be laminated to the insulatingcore 46 by the use of an adhesive 49 after formation of the insulatingcore material 46. Alternatively, theacoustic membrane 20 may be adhered to the insulatingcore material 46 either during fabrication by introducing theacoustic membrane 20 to the forming section of a glass wool process or prior to curing the glass wool.FIG. 7 depicts aninsulation panel 74 in which theacoustic membrane 20 is affixed to the insulatingcore material 46 with an adhesive 49. A backing facer may optionally be applied to the back surface of the insulatingcore material 46 of insulation panel 74 (embodiment not illustrated). InFIG. 7 , it is to be appreciated that theacoustic membrane 20 forms the external or exposed surface of theinsulation panel 74. Theacoustic membrane 20 may be fabricated to resemble stucco, bathroom tiles, wood, etc. In addition, theacoustic membrane 20 may be formed of any of the materials set forth above. For example, the acoustic membrane may be formed of a waterproof material such as a dense WUCS material, which would enable theinsulation panel 74 to be used in places where thepanel 72 may be exposed to water or have a need to be cleaned, such as in a shower stall, near a bathroom sink, in a kitchen, in a recreational room, etc. -
Insulation panel 74 may be utilized in the removable panel finishing system described above in an manner very similar toinsulation panel 40. For example, as shown inFIG. 8 , aframe member 22 may be mechanically and/or adhesively fastened to astud 12. Twoinsulation panels 74 are retained between thebase plate 24 of aframe member 22 and thedivider member 50 by the retainingarms 52. As with the embodiment described above,divider member 50 is releasably connected to theframe member 22 for ease of removing theinsulation panels 74. Theinsulation panel 74 is positioned between thedivider member 50 and thebase plate 24 in a manner such that theacoustic membrane 20 faces the inside of the room. It is also envisioned that theinsulation panel 74 may further include a fabric facer and that theinsulation panel 74 may be positioned between thedivider member 50 and thebase plate 24 such that the fabric facer faces towards the inside of the room. - It is to be appreciated that in both the
insulation panel 40 and theinsulation panel 74, the thickness of theacoustic membrane 20 and the insulation panel are not particularly limited, so long as the total thickness of theacoustic membrane 20 and the insulation panel do not exceed the length of thearms 26 of theframe member 22 to any appreciable degree. The thickness is desirably a thickness in which theinsulation panel 40 orinsulation panel 74 fits snugly between the retainingarms base plate 24 of theframe member 22. If the thickness of theacoustic membrane 20 and theinsulation panel arms base plate 24 would form, which would cause the insulation panel 40 (or the insulation panel 74) to move freely between the retainingarms base plate 24 of theframe member 22. - In another exemplary embodiment of the present invention, the
insulation panel 74 may be used to form a drop ceiling, such as in a basement or other room. An unfinished basement is typically formed of a masonry wall 80 (e.g., cinder blocks) andsub-floor framing members 82 as shown generally inFIG. 9 . A drop ceiling may be formed utilizing the removable panel system described above in conjunction withinsulation panel 74. An example of the positioning of a framing member andinsulation panels 74 is depicted inFIG. 10 . A framingmember 22 is mechanically and/or adhesively fixed to a sub-floor framing member such that thearms 26 of the framingmember 22 face downwardly and into the interior of the basement. Twoinsulation panels 74 are retained between thebase plate 24 of theframe member 22 and thedivider member 50 by the retainingarms 52. As with the embodiments described above, thedivider member 50 is releasably connected to theframe member 22 for ease of removing theinsulation panels 74. Eachinsulation panel 74 is positioned between thedivider member 50 and thebase plate 24 in a manner such that theacoustic membrane 20 faces the inside of the room. - In an alternate embodiment for forming a drop ceiling utilizing the removable panel finishing system described herein, the
acoustic membrane 20 is mechanically affixed to thesub-floor framing members 82 in a continuous or successive manner (not illustrated). Joints between successiveacoustic membranes 20 may be sealed, such as by tape or caulk, to form a substantially continuousacoustic membrane 20 across the ceiling. A framingmember 22 may be mechanically and/or adhesively affixed to thesub-floor framing members 82 such that thearms 26 of the framingmember 22 face downwardly and into the interior of the basement. Suitable mechanical fasteners include any conventional mechanical fastening devices such as staples, nails, screws, tacks and the like.Insulation panels 40 are positioned between thebase plate 24 of theframe member 22 and retainingarms 52 of a divider member with the fabric facing 44 facing the internal portion of the room. As with the embodiments described above, thedivider member 50 is releasably connected to theframe member 22 so that theinsulation panels 40 can be easily removed. It is to be appreciated that the drop ceiling embodiments are described herein are described with reference to an unfinished basement, but could equally apply to any unfinished room. - The invention of this application has been described above both generically and with regard to specific embodiments. Although the invention has been set forth in what is believed to be the preferred embodiments, a wide variety of alternatives known to those of skill in the art can be selected within the generic disclosure. The invention is not otherwise limited, except for the recitation of the claims set forth below.
