Definitions

  • the present invention relates to packaging, and more particularly to packaging for insulation products.
  • Removal of the tape can cause tearing in the FSK layer, thereby compromising the integrity of the vapor barrier layer. It is believed that sealing the plastic bags before the water has completely dried prolongs the drying process and is a main cause of the adhesion problem. However, it is neither practical nor preferred to delay packaging of the product to employ a drying process, which necessarily adds costs and time to the manufacturing process.
  • a packaged insulation product comprising an insulation product oriented for storage or transportation and disposed in a removable package.
  • the package includes a vapor-permeable membrane.
  • the packaged insulation product comprises an insulation product comprising a fiberglass mat and a facing layer bonded to a first major surface thereof.
  • the insulation product is compressed in roll or folded form for storage or transportation thereof and secured by a tape disposed around the insulation mat and contacting the facing layer.
  • the tape includes a water-based or activated adhesive and the insulation product is disposed in a removable package comprising a non-perforated smart vapor retarder membrane, wherein the moisture vapor permeability of the smart vapor retarder membrane increases with increases in ambient humidity.
  • the membrane allows drying to occur through the process of vapor diffusion, thereby improving the speed of drying of the adhesive that couples the tape to the facing layer, which, it is believed, prevents the undesired strong bond therebetween that can lead to tearing of the facing layer upon removal of the tape.
  • the membrane also allows other trapped moisture to escape from the packaging, thereby limiting odors in the insulation mat typically associated with excess trapped moisture.
  • the membrane comprises a smart vapor retarder such as a Nylon film not only because of its excellent moisture vapor permeability characteristics, but for its other physical characteristics as well.
  • Nylon is a rather tough plastic material with a high tensile strength. Nylon films also exhibit low flammability even without any fire protecting chemicals. The film can typically be used without any additives, which improves its recyclability.
  • the use of a packaging comprising a smart vapor barrier also allows for packaging of the product immediately or soon after winding rather than temporarily setting the product aside unpackaged for air drying.
  • a packaging for storage or transportation of an insulation product in roll or folded form comprising a vapor-permeable membrane sized to envelope the insulation product.
  • a method of packaging an insulation product comprises the steps of providing an insulation product in rolled or folded form for storage or transportation, disposing the insulation product in a removable package comprising a vapor-permeable membrane, and closing the package.
  • FIG. 1 is a side elevational view of a rolled insulation product
  • FIG. 1A is a front elevational view of the rolled insulation product of FIG. 1 ;
  • FIG. 2 is an exploded view illustrating the placement of the rolled insulation product of FIG. 1 into a packaging
  • FIG. 3 is a cross-sectional view of the rolled insulation product of FIG. 1 taken along Line 3 - 3 ;
  • FIG. 4 is a perspective view of a packaged insulation product
  • FIG. 5 illustrates a packaged product comprising an alternative embodiment of a vapor-permeable packaging
  • FIG. 6 illustrates a packaged product comprising a plurality of insulation products therein.
  • FIG. 1 is a side elevational view of a rolled insulation product or batt 10 comprising insulation mat 8 rolled for storage and/or transportation after packaging.
  • insulation mat 8 is generally provided in lengths between about 50-150′ with a width between about 2-6′.
  • insulation mat 8 is a low density product having a density in the range of about 0.5-2.5 lb/ft 3 (8-40 kg/m 3 ).
  • the thickness of the insulation mat 8 is generally proportional to the insulated effectiveness or “R-value” of the insulation.
  • the insulation mat has a thickness in the range of about 1-3′′.
  • Insulation mat 8 is preferably formed from organic fibers such as polymeric fibers or inorganic fibers such as rotary spun glass fibers, textile glass fibers, stonewool (also known as rockwool) or a combination thereof. Mineral fibers, such as glass, are preferred.
  • the fibers are often 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, nylon, urethane and furan binder may also be utilized in some embodiments.
  • insulation mat 8 has a facing layer 6 , typically a vapor retarder facing layer, adhered to a major surface thereof.
  • Reference 12 identifies the end of the rolled mat 8 .
  • the facing layer comprises a laminate layer such as a FSK (foil (e.g., aluminum)-scrim-Kraft paper) or PSK (plastic-scrim-Kraft paper) laminate layer.
  • the FSK or PSK layer may be coated with a bituminous adhesive material, such as asphalt, for securing the laminate layer to the mat 8 or, more typically, a water based adhesive such as an acrylic or polyvinyl acetate.
  • a bituminous adhesive material such as asphalt
  • a water based adhesive such as an acrylic or polyvinyl acetate
  • the facing layer 6 can be secured to the major surface of the insulation mat 8 by a hot-melt adhesive.
  • the insulation mat 8 is typically compressed after manufacture and then 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. Up to seven or more mats 8 can be stored within the same packaging.
  • the diameter “D” of each rolled product 10 is typically between about 1.5-3′, more typically about 20-30′′, with a width “W” typically around 48′′.
  • the insulation product tends to quickly “fluff up” to its prescribed label thickness for insulation.
  • the mat 8 Prior to packaging, the mat 8 is wound on a winding machine, such as a Dyken winder, and the rolled insulation product is held in roll form with one or more paper tape strips applied to the circumference of the roll.
  • the tape 14 is wrapped around the circumference of each of the rolled products and coupled to facing layer 6 , specifically, to the foil or plastic portion of the FSK or PSK laminate layer, respectively.
  • Each product includes one or more strips of tape, typically two strips of tape 14 as shown in FIGS. 1 and 1 A.
  • the tape 14 is typically a paper tape with a water based or activated adhesive, such as a gummed, non-reinforced heavy duty paper tape available from Holland Manufacturing Co., Succasunna, N.J.
  • the wound product which is held in place by the tape 14 , is then packaged in a removable package, such as bag 16 (as shown in FIG. 2 ), to protect it from damage and keep the insulation clean and dry.
  • Bag 16 preferably comprises a non-perforated vapor-permeable membrane that allows water from the water based or activated adhesive on tape 14 and other water present in rolled batt 10 to evaporate from bag 16 into the surrounding environment.
  • the vapor-permeable membrane can be from 0.1-100% of the surface area of the bag 16 .
  • the vapor-permeable membrane can be a patch on a standard polyethylene bag, for example, as shown in FIG. 6 described below.
  • a water vapor permeable but substantially liquid impermeable material includes a polyurethane film.
  • the film can be treated for improving the water-resistant properties while not reducing its ability to be water vapor permeable.
  • materials which have been reported as being effective for improving the water-resistant properties of layers are the following: lattices of vinyl acetate, vinyl chloride, acrylics, acrylonitrile, and ethylene in addition to the monomers of styrene, butadiene, and isoprene, poly(vinyl alcohol), with or without a minor amount of poly(vinyl acetate); metallic resinates; wax or asphalt or mixtures thereof; a mixture of wax and/or asphalt and also cornflower and potassium permanganate; water insoluble thermoplastic organic materials such as petroleum and natural asphalt, coal tar, and thermoplastic synthetic resins such as poly(vinyl acetate), poly(vinyl chloride) and a copolymer of vinyl acetate and vinyl chloride and acrylic resins;
  • the vapor-permeable membrane comprises a smart vapor-permeable membrane, i.e., a membrane that changes its moisture vapor permeability with the ambient humidity condition, such as Nylon.
  • the bag 16 or portion of the bag 16 , is formed from a material such as the MEMBRAINTM Smart Vapor Retarder available from CertainTeed Corporation of Valley Forge, Pa.
  • This smart vapor retarder is a polyamide film, specifically about 99-100% by weight Nylon 6, blown to approximately 2-mil thickness. The film changes its permeability with the ambient humidity condition.
  • the product's permeance is 1 perm or less when tested in accordance with ASTM E96, dry cup method, and increases to greater than 10 perms using the wet cup method.
  • This process allows the closed packaging to increase its drying potential dependent upon the presence of water inside the package, such as water from the adhesive tape 14 .
  • the product reacts to relative humidity by altering pore size, allowing water vapor to pass through it. This transformation allows drying to occur through the process of vapor diffusion, thereby improving, after packaging, the speed of drying of the adhesive that couples the tape 14 to the foil or plastic layer of facing layer 6 , which, it is believed, prevents the undesired strong bond therebetween that can lead to tearing of facing layer 6 upon removal of the tape 14 .
  • the film also allows other trapped moisture to escape from the packaging, thereby limiting odors in the insulation mat typically associated with excess trapped moisture.
  • Nylon film smart vapor retarders are preferred not only because of their moisture vapor permeability characteristics, but for other physical characteristics as well.
  • Nylon is a rather tough plastic material with a high tensile strength.
  • a membrane of about 50 ⁇ m (2 mils) has mechanical properties equivalent to a polyethylene film of 150 ⁇ m (6 mils) thickness.
  • Nylon films also exhibit low flammability even without any fire protecting chemicals. The film can typically be used without any additives, which improves its recyclability.
  • the packaging environment have relatively low humidity, which promotes diffusion of water from the packaged product (i.e., the higher humidity environment) to the surrounding low humidity environment, once the packaging is closed, storing the product in higher humidity environments should not be a problem after the water has substantially diffused out of packaged product.
  • the use of a packaging comprising a smart vapor barrier also allows for packaging of the product immediately or soon after winding rather than temporarily setting the product aside unpackaged for air drying.
  • FIG. 4 is a perspective view of a packaged insulation product 18 , i.e., a rolled insulation batt 10 disposed in a sealed package 16 .
  • the package 16 is sealed or otherwise closed at any open ends, such as by a wire tie 20 or other means for closing or sealing the package 16 .
  • the preferred packaging 16 includes a non-perforated smart vapor retarder layer.
  • the packaging may includes perforations for allowing water vapor to escape.
  • FIGS. 1, 1A , and 2 illustrate the insulation mat 8 as being provided in rolled form for packaging.
  • orientations suitable for packaging for transportation or storage and not specifically show such as folded orientations or other stacked orientations, may also be employed.
  • the insulation product may be secured in its orientation by a tape and in some embodiments, no tape or other sealing means may be used prior to packaging.
  • FIG. 5 is a perspective view of a packaged product 18 A comprising an alternative embodiment of a package.
  • package 16 A comprises a bag, such as a conventional polyolefin (e.g., polyethylene) bag having one or more patches 22 comprising a vapor-permeable membrane as described above.
  • the patch 22 may be stitched, heat sealed or otherwise coupled in any other viable manner to bag 16 A to provide a vapor window to the outside environment for diffusion of water thereto.
  • FIG. 6 illustrates an embodiment of a packaged insulation product 18 B comprising more than one insulation batt 10 within a bag 16 .
  • the insulation batts 10 are shown in phantom.
