Definitions
- the present invention relates to insulation products and methods of making the same, and more particularly to insulation products having facing layers thereon and methods of making the same.
- Fibrous Insulation Blankets issued April 22, 2003, (Weinstein I) the entirety of which is hereby incorporated by reference herein, describes an elongated insulation blanket that has a series of cuts extending between the major surfaces of the blankets with successive cuts being separated by a series of separable connectors located intermediate the major surfaces of the blanket.
- Each series of separable connectors holds together adjacent sections of the blanket for handling, but are separable by hand so that the blanket can be handled as a unit for insulating a cavity having a predetermined width or separated by hand into two or more sections at one or more of the series of the separable connectors for insulating a cavity having a lesser, nonstandard width.
- the blanket has a facing bonded thereto by a bonding agent, having one or more perforated lines in the facing that permit the facing to be separated by hand at each series of cuts and separable connectors.
- Insulation Blanket issued October 22, 2002 (Weinstein II), the entirety of which is hereby incorporated by reference herein, also describes insulation mats having permeable sheets on a first and or second major surface of that mat, where the permeable sheets are separable by hand due to the low tear strength of the sheets.
- the sheets are described as having the tear strength about equal to the tear strength or tensile strength of facial or bathroom tissue.
- These permeable sheets are not vapor barrier facing layers, which are also shown coupled to the mats. [0006] Therefore, there is a need for an insulation product, and method of making the same, that can be formed into sections having nonstandard widths, but without significant field work and without compromising the vapor barrier formed on the insulation product.
- An insulation product comprising an insulation mat comprising randomly oriented fibers.
- the mat has first and second major surfaces and a pair of side portions.
- a vapor retardant facing layer is bonded to at least one of the major surfaces of the mat.
- the facing layer has a fiber orientation such that the facing layer has a ratio of machine direction tensile strength to cross machine direction tensile strength which permits the facing layer to be separated by hand along a substantially straight line selected in the machine direction.
- a method of manufacturing an insulation product comprising the following steps: providing an insulation mat comprising randomly oriented fibers, the mat having first and second major surfaces and a pair of side portions; and adhering a vapor retardant facing layer to at least one of the major surfaces of the mat, the facing layer having a fiber orientation such that the facing layer has a ratio of machine direction tensile strength to cross machine direction tensile strength which permits the facing layer to be separated by hand along a substantially straight line selected in the machine direction.
- a facing layer having reduced width and/or paper weight but of sufficient cross machine direction tear strength may be achieved.
- the process of forming a faced insulation product is also simplified in that various facing layers each having different perforation locations are not required for different modular products and need not be stored and/or the step of perorating the facing layer can be eliminated or reduced. Cost saving attributable to materials and storage thereof may be realized.
- an insulation product including an insulation mat comprising randomly oriented fibers, the mat having first and second major surfaces and a pair of side portions, and a facing layer comprising cellulosic fibers, such as a cellulosic paper, bonded to the insulation mat with a vapor retardant adhesive.
- the facing layer includes a central portion coextensive with the at least one major surface and at least one tab portion adjacent the central portion and extending beyond the at least one major surface.
- the layer or paper has a fiber orientation such that a ratio of machine direction tensile strength to cross machine direction tensile strength in the facing layer is at least about 4:1, preferably about 4:1 to 20:1. and more preferably 6:1 to 15:1.
- the facing layer is also preferably non- perforated in at least the machine direction.
- the insulation mat includes a plurality of separable segments. The segments are coupled to each other along at least one plane oriented in the machine direction.
- a method of forming a reduced width insulation product from a master insulation product for installation in a structure comprising the following steps: (a) providing a master insulation product comprising an insulation mat comprising randomly oriented fibers, the mat having first and second major surfaces and a pair of side portions; and a facing layer comprising a cellulosic paper bonded to the insulation mat with a vapor retardant adhesive, the facing layer having a fiber orientation such that the facing layer has a ratio of machine direction tensile strength to cross machine direction tensile strength which permits the facing layer to be separated by hand along a substantially straight line selected in the machine direction, wherein the insulation mat includes a plurality of separable segments, the segments being coupled to each other along at least one plane oriented in the machine direction; and (b) separating the facing layer in the machine direction substantially along a plane from said at least one plane to remove at least one of the separable segments from the master insulation product, thereby providing a reduced width insulation product.

- “Mat” means a fibrous material consisting of randomly oriented filaments, short fibers (with or without a carrier fabric), or swirled filaments held together with a binder, and are available in blankets of various thicknesses, widths, weights, and lengths.
- “Insulation Mat” includes insulation boards, such as duct boards, insulation batts and acoustic insulation;
- “Machine Direction” as used herein with respect to a layer means the direction in which the greater number of the fibers of a sheet of paper tend to be oriented as a result of the forward motion of the wire of the papermaking machine.
- the paper so produced is stronger in the machine direction, and also experiences less dimensional variation in the machine direction due to changes in humidity.
- Cross Machine Direction with respect to a layer means the direction at right angles to the machine direction
- Teensile Strength means the load or force required to break a specimen
- Tear Strength means the force required to tear a layer at a precut edge, to a specific length, and measured in milli-Newton. This property is typically importance for printing, writing and wrapping papers.
- Insulation materials generally span the range from light weight, flexible and resiliently compressible foams and nonwoven fiber webs to rigid or semi-rigid boards.
- these insulating materials have densities in the range of about 0.5-7 lb/ft 3 (8-112 kg/m 3 ).
- Foam and nonwoven fiber web materials are usually provided in continuous sheeting that is sometimes cut to preselected lengths, thus forming batts.
- These articles are usually characterized as "low density,” having a density in the range of about 0.5-6 lb/ft 3 (8-96 kg/m 3 ), and preferably about 1-4 lb/ft 3 (16-64 kg/m 3 ), and more preferably 0.3 to 1.5 lb/ft 3 (4.8-24 kg/m 3 ).
- the thickness of the insulation blanket or mat is generally proportional to the insulated effectiveness or "R-value" of the insulation.
- low density insulation mats typically have a thickness between about 3.5-10 inches.
- rigid to semi-rigid insulation boards tend to have densities in the higher portion of the range, at about 2-7 lb/ft 3 (32-112 kg/m 3 ), and preferably at about 4-7 lb/ft (64-112 kg/m ).
- These boards customarily are produced as sheets typically having a thickness in the range of about 0.25-2 inches, and more preferably about 0.5-2 inches, and about 2-4 feet wide by about 4-12 feet in length.
- Insulation product 100 includes insulation sheet 10, which may comprise a high or low density insulation mat or board, as described above, formed from organic fibers such as polymeric fibers or inorganic fibers such as rotary glass fibers, textile glass fibers, stonewool (also known as rockwool) or a combination thereof. Mineral fibers, such as glass, are preferred.
- Insulation sheet 10 includes first and second major surfaces 12, 13 and longitudinal side portions 14, 15.
- a vapor retarder facing layer 17 which may be a cellulosic paper, typically formed from Kraft paper, coated with a bituminous adhesive material, such as asphalt, polymeric resin, or polymeric film, such as LDPE (low density polyethylene), or a combination of these materials, is provided on one major surface 12 of the insulation sheet 10.
- the facing layer 17 and bituminous layer 16 together form bitumen-coated Kraft paper 31.
- the coating is preferably applied in a sufficient amount so as to provide an effective barrier or retarder for water vapor, for example, so as to reduce the water vapor permeability of the Kraft paper to no more than about one perm when tested by ASTM E96 Method A test procedure.
- the facing layer 17 can be secured to the bottom of major surface 12 of the insulation sheet 10 by an adhesive, such as a hot-melt adhesive. Additional details of facing layer 17 are provided below.
- Insulation product 100 may include a pair of optional side tabs 18 and 19 that can be fastened to wooden or metal studs, for example.
- Various known configurations for side tabs or flaps 18 and 19 are known.
- the facing layer 17 can be water vapor impermeable or permeable, depending on its makeup, degree of perforation and intended use.
- insulation sheet 10 is a low density matt or batt formed from glass fibers bound together with a heat cured binder, such as known resinous phenolic materials, like phenolformaldehyde resins or phenol urea formaldehyde (PUFA). Melamine formaldehyde, acrylic, polyester, urethane and furan binder may also be utilized in some embodiments.
- the insulation is typically compressed after manufacture and packaged, so as to minimize the volume of the product during storage and shipping and to make handling and installation of the insulation product easier. After the packaging is removed, the batt insulation product 100 tends to quickly "fluff up" to its prescribed thickness for insulation.
- insulation mat 10 includes first separable segment
- mat 10 is illustrated as including two separable segments 10a, 10b, this is for illustrative purposes only and mat 10 can include any number of separable longitudinal segments.
- Mat 10 may be sized to fit between support members spaced at standard widths, while segments 10a, 10b can be sized to accommodate anticipated, nonstandard or standard spacings. In one embodiment of the mat 10 of FIG. 1, mat 10 has a total width between about 11-24".
- section 10a has a width between about 9-13" and section 10b has a width between about 2-7".
- FIG. 1. illustrates adhesive layer coupling segments 10a and 10b together along substantially the entire thickness and length of the insulation mat 10, this is not a requirement.
- the adhesive layer need not extend the entire length of the interior surfaces of the segments in plane 22. Rather, the adhesive layer can be intermittently applied on the surfaces along the length of segments 10a and/or 10b.
- the adhesive layer 20 may comprise one ore more adhesive strips located between the first and second major surfaces 12, 13 and extending along the inner surfaces segments 10a and/or 10b.
- mat 10 is approximately 15" wide and has a thickness of approximately 3.5".
- 1" adhesive bond should provide sufficient adhesion between separable segments 10a and 10b.
- a first longitudinal strip of adhesive having a height of about .5" is applied approximately 1" above the first major surface 12 and along an interior surface of segment 10a and/or 10b and a second longitudinal strip of adhesive having a height of about .5" is applied approximately 1" below the second major surface 13 and along an interior surface of segment 10a and/or 10b.
- mat 10 is approximately 15" wide and has a thickness of approximately 6.25".
- a 2" adhesive bond should provide sufficient adhesion between separable segments 10a and 10b.
- a first .5" longitudinal strip of adhesive is applied approximately 1" above the first major surface; as second .5" longitudinal strip of adhesive is applied approximately .5" above the first longitudinal strip; a third .5" longitudinal strip of adhesive is applied approximately 1.25" above the second longitudinal strip; and, a fourth .5" longitudinal strip of adhesive is applied approximately .5" above the third longitudinal strip and approximately 1" from the second major surface 13.
- Fig. 2 is a bottom plan view of insulation product 100. The dashed lines illustrate the position of tabs 18 and 19, and do not illustrate perforations. Insulation product 100 has a defined width W and length L, which may vary depending on whether insulation product 100 is provided in roll or batt form.
- facing layer 17 comprises a cellulosic fiber containing material, such as a cellulosic paper, preferably a directional Kraft paper having fibers oriented in substantially the machine direction, as opposed to the cross machine direction.
- a cellulosic paper preferably a directional Kraft paper having fibers oriented in substantially the machine direction, as opposed to the cross machine direction.
- a polymeric film, woven knit or nonwoven with anisotropic mechanical properties can be used. Mixtures of polymeric, cellulosic and inorganic fibers can be used.
- These alternative facing layers may be coupled to the mat with, for example, a hot melt adhesive.
- Facing layer 17 is shown coextensive with major surface 12 of insulation mat
- the EXOPACK 40# product exhibits a machine direction tensile strength to cross machine direction tensile strength ratio of about 2.5:1 but a machine direction to cross machine direction tear strength ratio of only about 5:4 as discerned from the product specification/vendor sample property sheets. This relatively unitary tear strength ratio does not allow for the easy creation of clean, straight tears in the paper in the machine direction without the aid of a cutting tool.
- the paper exhibits unintended and significant propagation of the tear in the cross direction.
- the fiber orientation is such that the facing layer has a ratio of machine direction tensile strength to cross machine direction tensile strength which permits the facing layer to be separated by hand along a substantially straight line selected in the machine direction, and thus the tear strength of the layer 17 is sufficiently higher in the cross machine direction than the machine direction, the difference should not be so great such that the separable segments are prone to unplanned separation, such as during shipping or packaging or during deployment of product 100 as a unitary product rather than separable segments.
- the ratio of the machine direction tensile strength to cross machine direction tensile strength in facing layer 17 is at least about 4:1, and more preferably at least about 6:1, and still more preferably at least about 8:1. In one embodiment, the ratio is between about 4:1 to 20:1, and more preferably, between about 6:1 to 15:1, and more preferably between about 8: 1 to 11 : 1.
- the preferred facing layer has been described in terms of its fibers and fiber orientation being selected to provide a specified ratio of machine direction tensile strength to cross machine direction tensile strength sufficient to provide a cross machine direction tear strength to machine direction tear strength, such as measured by the Elmendorf Tear test.
- the machine direction and cross direction tear strengths are not believed to be linearly related to tensile strength, and do depend at least in part on paper weight and thickness.
- the ratio of the machine direction tensile strength to cross machine direction tensile strength is preferably selected such that facing layer 17 can be torn or otherwise easily separated along plane 22 (FIG. 2) in the machine direction (parallel to longitudinal edges 14, 15) that separates the separable segments of mat 10 without the use of perforations in layer 17 and without the propagation of the tear significantly in the cross machine direction.
- the absence of perforations in layer 17 prevents possible breaches of the vapor barrier in layer 3 1 at the perforations, particularly when the insulation product is used between support members spaced at standard distances, i.e., when the separable segments are not removed from the mat 10. Still further, the layer 17 can be torn in the machine direction at any location along the width W of mat 10. This feature allows the manufacturer to locate the connection between the separable segments of insulation mat 10 (shown at adhesive connection 20 of FIG. 1) at any point along the width of mat 10 without changing the configuration of layer 17. With prior art mats, the perforation location in the facing layer would have to be adjusted to align with the connection of the separable segments if they were resized.
- FIG. 1 illustrates separable segments 10a and 10b and facing layer 31 partially separated starting from first major surface 12 towards second major surface 13.
- the segments can be separated starting from second major surface 13 towards first major surface 12 as shown in the partial separation illustrated by FIG. 2 A.
- the connection between separable segments and the tear strength/tensile strength of the facing layer 17 in the machine direction are preferably selected to allow for a field separation, such as by tearing by hand without the aid of a tool, such as a cutting tool, although this option is not precluded.
- layer 17 prior to tearing facing layer 17 in the field, layer 17 is creased at a selected location in the machine direction to further aid is creating a straight, clean tear.
- segments 10a and 10b can be separated starting from second major surface 13 towards first major surface 12 and towards facing layer 31. Once segments 10a and 10b are separated, facing layer 31 is then creased at the separation between the separable segments and then torn in the machine direction in a clean, longitudinal tear to form two separate faced longitudinal mat segments.
- the layer 17 may be pre-creased in the machine direction at the desired tear location, i.e., creased prior to gluing or otherwise bonding the layer 17 to the major surface of the mat. This embodiment 100B is illustrated in FIG.
- the increased machine direction strength also provides increased resistance against tearing in tabs 18 and 19 when tabs 18 and 19 are secured to framing members, such as by staples or other fastening means.
- tabs 18 and 19 may be folded one or more times to increase the thickness of tabs 18 and 19, thereby increasing their tear strength, the improved tear resistance may permit tabs 18 and 19 to comprise a single layer of paper 17, i.e., tabs 18 and 19 may be deployed as unfolded tabs.
- layer 17 comprises a 15-40 pound/2880 ft 2 directional Kraft paper, more preferably a 27-37 pound directional Kraft papers, such as is available from Lydall, Inc. of Manchester, Connecticut. Examples of directional Kraft paper available from Lydall, Inc. include:
- the 18-l/2# Manning® 456 paper has a machine direction to cross machine direction tensile strength ratio of about 8.97:1.
- the ratios for the 27-l/2# Manning® 556 and 35# Manning® 532 products are about 10.29:1 and 6.42:1, respectively.
- Various trials were run to face glass fiber insulation mats with traditional non- directional Kraft paper and directional Kraft paper. The line speed was run at 120 ft/min using 15" x 93" folded Kraft batts split into two 7.5" wide pieces connected by an approximately 1/8" strip of uncut mat along the bottom of the mat. In the first trial, standard, non-directional EXOPACK 40# semi-extensible Kraft paper available from Canfor Co.
- the 37# directional Kraft paper was creased prior to bonding to the insulation batt. A significant improvement was observed in the product; a hand tear or rip of the facing layer followed the crease very well until about the last 3" of the product.
- 27# Manning® directional uncreased Kraft paper was bonded to the insulation batt. It was observed that the 27# paper tore more easily than the 37# sample, but the paper did not follow the split between the batt segments as well as the 37# creased sample.
- the 27# paper was creased prior to bonding to the insulation batt.
- the trial production runs illustrated that the directional Kraft paper does help create a fault plane for separation of the facing in the machine direction at a selected location. It was also observed that a crease, at least with the papers tested, is preferred to help define the fault plane, so that the paper does not select an undesired path of least resistance during separation.
- the 37# directional Kraft paper appears to be an acceptable facing layer when creased in the desired location, such as by creasing bars. It is believe that interlocking rollers may be preferred for creating the crease in full production.
- the 27# facing layer is potentially too thin in its current form for reliable use. It is believed that a directional Kraft facing layer between about 27-37#, such as 32# may provide an optimum balance of strength and cost.
- FIG. 3 illustrates an exemplary method of adhering facing layer 31 to insulation sheet 10.
- sheet 10 which preferably comprise two or more separable longitudinal segments, may be presented by the feed conveyer 104 to a heated roll 102, to which is simultaneously supplied a continuous web of bitumen-coated Kraft paper web 31, fed between the heated roll 102 and the sheet 10.
- the web of Kraft paper fed via roller 102 after being bitumen-coated is supplied from a roll 108 on payout stand 118, through an accumulator 138 for tensioning the Kraft paper web 31.
- the outside surface of the web can be marked at a marking station 114 with identifying information such as the R- value of the glass fiber sheet and the production lot code before the Kraft paper web 3 1 is applied to the bottom of the sheet 10.
- identifying information such as the R- value of the glass fiber sheet and the production lot code
- the edges of the Kraft paper web 31 axe folded over to form the side tabs 18, 19 (FIG. 1) just prior to the web contacting the heated roll 102.
- the Kraft paper web 31 is oriented so that the bitumen-coated side of the Lraft paper web 31 faces the bottom of the glass fiber sheet 10 and so that the paper has a higher tensile strength in the conveyed direction of sheet 10 (i.e., along the length of sheet l O) than across the width of sheet 10.
- the temperature is preferably selected to provide enough heat to soften the bituminous coating, which is supplied from bitumen source 120, such that the bitumen-coated Kraft paper web 31 adheres to the underside of the glass fiber sheet 10.
- the faced glass fiber sheet is transported away from the heated roll 102 by a tractor section 106 and delivered to a chopper 112, which periodically chops the faced glass fiber sheet to form insulation product 100 of appropriate length, e.g., 48-105" for insulation batts and 32-100' for insulation rolls.
- the mat 10 Prior to or after facing the mat 10 with facing layer 31, the mat 10 may also be provided to a sheer (not shown), which slices the at into sections or strips having desired widths, e.g., 15", some of which may be further sectioned to form the separable segments of mat 10 discussed above.
- the insulation products 100 so formed are then transported to packaging equipment (not shown). If the sheer is disposed prior to application of facing 31, facing layer 31 is provided from separate rolls 108 spaced to provide an individual facing layer 31 of appropriate width to each sliced section of sheet 10.
- mat 10 includes a plurality of separable segments.
- mat 10 includes two or more segments that are coupled together along their lengths by an adhesive 20.
- U.S. Patent Application Serial No. XX/XXX,XXX [Attorney Docket No. D0932-00438], entitled “Method and Apparatus for Adhering Together Lanes of Compressible Products", filed February 11, 2004 and U.S. Patent Application Serial No. 10/690,295, entitled “Separable Fihrous Insulation”, filed October 21, 2003, the entirety of which are hereby incorporated by reference herein, describe segmented mat 10 and exemplary methods of making the same.
- a wedge device is inserted between two separate lanes of a compressible product, such as an insulation mat, to split apart at least a portion of the lanes of product.
- Either the wedge device or the separate lanes of the compressible product are advanced to move the wedge device and lanes relative to one another.
- An adhesive is applied onto an inside wall of one or both of the lanes of the compressible product while at least a portion of the lanes are split.
- the inside walls of the lanes are then contacted to form a single adhered product, such as mat 10 shown in FIG. 1A including a plurality of separable segments.
- FIGS. 2-7 illustrate a mat having perforated cuts therethrough, leaving separable connectors (formed from the insulation mat) remaining to connect the lengthwise segments of the insulation mat.
- Weinstein I also discloses a method of forming the perforated mats using water jet cutting or compression cutting stations and rotary cutting saw stations as shown in and described in connection with, for example, FIGS. 16-18 of Weinstein I Likewise, commonly assigned U.S. Patent Application Serial Nos.
- FIG. 4 is a perspective view of an insulation product 100 A including an insulation blanket having separable segments 10a and 10b coupled together and divided by kerf 24 formed, for example, using a chopping blade or saw.
- a modular faced insulation product that provides for user friendly field separation into smaller segments while not compromising the vapor retarder barrier thereon.
- a facing layer having reduced width and/or paper weight but of sufficient cross machine direction tear strength may be achieved.
- the process of forming a faced insulation product is also simplified in that various facing layers each having different perforation locations are not required for different modular products and need not be stored and/or the step of perforating the facing layer can be eliminated or reduced. Cost saving attributable to materials and storage thereof may be realized.
- the insulation product has been described as including a facing with its improved machine direction fiber orientation oriented along the length of the insulation product, such that the facing layer and mat can be split into separate longitudinal segments
- the facing layer may alternatively be adhered to the insulation mat such that the machine direction of the facing layer aligns with the width of the mat rather than the length of the mat.
- the mat of the insulation product may be made separable into mats of varying length rather than width.
