Vapor control facing for wall finishing system
A finishing system insulation panel includes a primary insulation board, a covering suitable to provide an aesthetically pleasing surface and a film bonding the covering to the primary insulation board. The film is configured to substantially retard the flow of air, moisture, and gases.
This application is a continuation-in-part application of U.S. patent application, Ser. No. 10/ 754,316, filed on Jan. 9, 2004 entitled, “INSULATION SYSTEM WITH VARIABLE POSITION VAPOR RETARDER”, which is incorporated herein by reference in its entirety.
TECHNICAL FIELDThe present invention relates generally to an insulated panel mounting system for building structures and, more particularly, to wall finishing systems capable of retarding the flow of air, moisture, and gases.
BACKGROUND OF THE INVENTIONHomeowners often desire to finish rooms, such as basements, in a manner which provides a comfortable and aesthetically pleasing atmosphere.
Most basements are constructed of common materials including cinder block walls or poured concrete walls. Left unfinished, cinder block or poured concrete basement walls can allow humidity into the basement, and also allow the loss of heat through the basement walls. Traditionally, basement walls have been finished by known methods including attachment of wood studs to the basement walls and subsequent attachment of an interior wall surface, such as drywall or paneling, to the wood studs. Insulation materials such as glass fiber insulation batts have been placed between the wall and the wall surface before attachment of the wall surface to the wood studs. In another known method, a granular or loose-fill fibrous insulation material is poured or blown into the spaces between the wall and the interior wall surface after the interior wall surface is attached to the wood studs.
A known method of finishing a room involves the use of insulative panels releaseably connected to installed frame members as developed by the assignee herein, Owens Corning, and as described in the Weir et al. U.S. Pub. No. 2004/0219853 A1 for a “Room Finishing System”, and the Hettler et al. U.S. Pub. No. 2005/0150183 A1 for an “Insulation System with Variable Position Vapor Barrier”, both of which are expressly incorporated herein by reference.
It would be advantageous if the insulative panels were finished with a facing capable of retarding the flow of air, moisture, and gases.

BRIEF DESCRIPTION OF THE DRAWINGS
The description and drawings disclose an insulation finishing system 10 for finishing a room. With reference to
The insulation finishing system 10 includes a plurality of lineals 20 which create primary insulation cavities 16, as shown in
The lineals 20 can be attached to the wall 12 in any suitable manner. In certain embodiments, the lineal 20 is attached to the wall 12 with suitable fasteners 14; however, in other embodiments, the lineal 20 can be affixed to the wall 12 with a suitable adhesive material or any other mechanism which provides attachment to the wall 12.
The insulation finishing system 10 further includes primary insulation boards 50. The primary insulation boards 50 may be made of any type of insulating materials, such as, but not limited to, fiberglass, fiberglass board, rock wool board, mineral board, or a foam board. The foam board may be formed from extruded or molded polystyrene, polyisocyanurate, phenolic, polyurethane, or other similar insulation materials.
The primary insulation boards 50 include a decorative facing 54 bonded to the outer surface of the primary insulation board 50, as best shown in
As best shown in
In certain embodiments, one or more of the lineal partitions members 24, 25 can include one or more inwardly extending detents 28a, 28b for securing the trim piece 40 in the lineal 20. The lineal base plate 22 can optionally include at least one break-away notch 29 that extends along the intersection of the lineal base retaining flange 22a and the lineal partition 24. The break-away notch 29 allows the installer to easily remove the lineal base retaining flange 22a so that the lineal 20 can be installed in a corner or other area such as against a window or door (not shown).
The insulation finishing system 10 also includes a plurality of trim pieces 40 which connect to the lineals 20 and retain the primary insulation boards 50 within the primary insulation cavity 16. As shown in
As shown in
In general, the trim retaining flanges 42a and 42b maintain the finishing system insulation panels 60 in the primary insulation cavities 16 and provide a decorative interface between adjacent finishing system insulation panels 60′. In certain embodiments, as shown in
As discussed previously, the primary insulation boards 50 include a decorative facing 54. As best shown in
Subsequent to the bonding of the softened film 58 to the covering 56, the softened film 58 is used to bond the covering 56 to the primary insulation boards 50. The bonding of the softened film 58 and the covering 56 to the primary insulation board 50 can be completed using various manufacturing methods including a continuous rolling operation in which the softened film 58, the covering 56 and the primary insulation boards 50 are fed together to form a finishing system insulation panel 60. Alternatively, a pressing operation can be used in which the softened film 58, the covering 56, and the primary insulation boards 50 are pressed together to form a finishing system insulation panel 60. Any other manufacturing operation can be used provided the manufacturing operation is sufficient to bond the softened film 58 and the covering 56 to the primary insulation board 50. Alternatively, subsequent to the bonding of the covering 56 to the softened film 58, the assembled covering 56 and softened film 58 can be cooled and can be held for further use in a convenient manner such as in rolls, stacked or any other storage manner sufficient to safely and conveniently store the assembly of the covering 56 bonded to the film 58. At a later time, the assembled covering 56 and the film 58 can be heated to soften the film 58 for bonding to the primary insulation boards 50.
In addition to bonding the covering 56 to the primary insulation board 50, the film 58 also substantially retards the flow of air, moisture, and gases, without requiring the use of a separate vapor or air barrier (not shown). The film 58 is made of a polymer material, such as polyurethane, nylon, ethylene vinyl acetate, polyethylene or any material suitable to bond the covering 56 to the primary insulation boards 50 and substantially retard the flow of air, moisture, and gases. The film 58 can have a softening point within the range of from approximately 190° F. to approximately 300° F. To effectively retard the flow of air, moisture, and gases, the film 58 has a permeability rating of between 0 to 35 grams per hour per square foot as determined by water vapor transmission tests, such as ASTM E96. Typical water vapor transmission tests, such as the ASTM E96, evaluate the transfer of water vapor through semi-permeable and permeable materials over a period of time. Alternatively, the film 58 can have a variable permeability rating of between 0 to 35 grams per hour per square foot to allow variation in the flow of air, moisture, and gases through the finishing system insulation panels 60 as seasonal changes in temperature and humidity occur. A known product that has a variable permeability rating is “MemBrain: The SMART Vapor Retarder” which is available from Certainteed Corporation. Air retarding performance of the film 58 is measured using air transmission tests, such as ASTM E1677 or other similar testing methods, which are useful in measuring the rate of air flow in building materials.
During the installation process of the insulation finishing system 10, various components may be installed in a step-wise fashion until the wall 12 is covered. An initial lineal 20 is fixed to a wall 12, thereby forming an initial primary insulation cavity 16. An initial finishing system insulation panel 60 is positioned in the initial primary insulation cavity 16, such that the end portion 51 of the initial finishing system insulation panel 60 is pressed against the lineal partition 24 using hand applied pressure. Only hand applied pressure is necessary to affect an interference fit between the end portion 51 of the finishing system insulation panel 60 and the lineal partition 24. Following installation of the finishing system insulation panel 60, a subsequent lineal 20 is pressed against the installed finishing system installation panel 60, again using only hand pressure, and the subsequent lineal 20 is fastened to the wall 12 using appropriate fasteners 14. This procedure is followed until the wall 12 is covered by the finishing system insulation panels 60. Alternatively, other installation techniques can be used.
In certain installations, a temporary clip, such as a scrap part of a lineal 20 and/or trim piece 40, can be used to hold the finishing system insulation panels 60 within the primary insulation cavity 16 during the sequential installation of subsequent finishing system insulation panels 60.
In a certain embodiment, the interference fit between the finishing system insulation panels 60 and the lineal partitions 24, 25 is in the horizontal direction a, as shown in
As shown in
As shown in
In summary, the insulation finishing system 10 includes finishing system insulation panels 60 and various mounting components such as lineals 20 and trim pieces 40. The finishing system insulation panels 60 include a covering 56 bonded to primary insulation panels 50 by a film 58. The film 58 both bonds the covering 56 to the primary insulation panel 50 and substantially retards the flow of air, moisture, and gases. The film 58 eliminates the use a separate vapor or air barrier.
In another embodiment, the insulation finishing system 110 includes a second layer of insulating materials and additional components for mounting the second layer of insulating materials. The insulation finishing system 110 includes lineal adaptors 130 that create secondary insulation cavities 118, as shown in
The lineal adaptors 130 include an adaptor base plate 132 with opposing adaptor retaining flanges 132a and 132b and a connector member 133 which extends from a bottom side of the adaptor base plate 132. The connector member 133 can have any desired shape so that the connector member 133 can fit within the lineal receiving channel 126. In the embodiment shown, the connector member 133 has generally convex walls 133a and 133b. In certain embodiments, the adaptor connector 133 snaps into the lineal partitions 124, 125 such that the adaptor connector 133 releasably retains the lineal adaptor 130 in engagement with the lineal 120. If necessary, the lineal adaptor 130 can be removed without damage to the lineal 120 or the lineal adaptor 130 itself. Additionally, the lineal partitions 134 and 135 allow a releasable connection to be formed between the lineal adaptor 130 and the trim piece 140. Referring again to
In certain embodiments, one or more of the adaptor partitions 134, 135 can include one or more inwardly extending detents 38a, 38b for securing the trim piece 140 to the lineal adaptor 130. The adaptor base plate 132 can optionally include at least one break-away notch 139 that extends along the intersection of the adaptor base retaining flange 132a and the adapter partition 134. The break-away notch 139 allows the installer to easily remove the adaptor retaining flange 132a so that the lineal adaptor 130 can be installed in a comer or other area such as against a window or door (not shown).
The insulation finishing system 110 further includes a plurality of finishing system insulation panels 180 having a covering 174 bonded to an outer surface of secondary insulation boards 170 by a film (not shown). When installed, the finishing system insulation panels 180 are located in the secondary insulation cavity 118.
The secondary insulation boards 170 may be made of the same materials used to make the primary insulation boards 50, as discussed previously.
The covering 174 and the film used to bond the covering 174 to the secondary insulation panels 170, as shown in
In certain embodiments, the primary insulation panel 50 has a first thickness and the secondary insulation panel 170 has a second, different thickness. It is to be understood that the R-values of the primary insulation panel 50 and the secondary insulation panel 170 may be determined for a particular geographic region.
In a manner similar to that discussed earlier with respect to the primary insulation panels 50, the finishing system insulation panels 180 can be installed against the adapter partitions 134, 135 in a step-wise fashion until the primary insulation panels 50 are covered. Alternatively, other installation techniques can be used.
As shown in
In summary, the insulation finishing system 110 includes a second layer of insulating panels and additional mounting components. The second layer of insulating panels includes a covering 174 bonded to the secondary insulation panels 170. The covering 174 includes a film (not shown) which both bonds the covering 174 to the secondary insulation panel 170 and substantially retards the flow of air, moisture, and gases. The film eliminates the requirement to use a separate vapor or air barrier.
