Definitions

  • This invention relates to a mineral fiber insulation blanket for insulating ductwork. More specifically, the invention relates to a mineral fiber insulation blanket incorporating a
  • strip of adhesive flange for securing adjacent blankets during installation thereof.
  • Insulation of heating, ventilating, and air conditioning ductwork is often provided through the application of a flexible blanket of an appropriate insulation material.
  • Such ductwork can be round, square or rectangular in cross sectional configuration.
  • the ductwork is made of metal and is used in commercial, industrial, and residential buildings.
  • the insulation material used to insulate such duct work is often comprised of mineral fibers, either fiber glass or rock wool.
  • FSK is a glass- scrim reinforced laminate of aluminum foil and kraft paper bonded together with a flame- retardant adhesive.
  • the inner kraft surface of the FSK laminate is adhesively bonded to the fiber glass blanket.
  • the flame-retardant properties of the adhesive utilized in conjunction with the facing are important in applications where building codes mandate the use of insulation materials which have such properties. Frequently, a water based adhesive material is utilized in bonding the facing material to the numeral fibers. For applications in which the insulation material will be subjected to high temperatures (heated air in ducts up to 350 degrees Fahrenheit), unfaced duct wrap is recommended.
  • Fiber glass duct wrap is commercially available in various densities and thicknesses
  • Increasing the density of the duct wrap improves its thermal performance. Heavier density duct wraps are more efficient insulators and provide better compression resistance during installation.
  • the thickness of the duct wrap insulation typically ranges from 1 1/2" to 3".
  • Duct wrap is sold in rolls of various lengths (usually from 50 to 100 feet ).
  • the width of the mineral fiber blanket utilized in producing rolls of duct wrap is typically 48 inches.
  • the facing material is typically 50" wide and is adhered to the mineral fiber blanket in such a way as to extend 2" over one lateral edge of the mineral fiber blanket thereby providing a stapling and taping flap, flange or tab which, in a completed installation, overlaps an adjacent section of insulation to assist in securing the sections together and to provide a continuous vapor retarding layer.
  • This flap, flange or tab can be referred to as a "factory fabricated flap.”
  • the material is installed by cutting appropriate lengths of material from the roll to accommodate the perimeter of the duct to be insulated, taking into account the thickness of the insulation material. Accordingly, a somewhat greater length of material is utilized than the perimeter of the ductwork.
  • Most duct wrap manufacturers provide a chart which specifies the additional length of material to be utilized in ducts of various perimeter lengths and cross sectional shapes. These charts also take the thickness of the duct wrap into consideration.
  • the length of insulation that is added due to the outside perimeter of the installed, compressed insulation being larger than the outside perimeter of the duct is known as "Stretch-Out Dimension," meaning the unrolled length of duct wrap sufficient to insulate a duct of a given perimeter material of a given thickness and density.
  • pipe insulation is generally less flexible than duct wrap and is sold in specific sizes to insulate pipe of a given diameter which is typically significantly smaller than the diameter of heating, ventilating and air conditioning ductwork.
  • the material is also sold in a cylindrical shape with a slit running the length of the cylinder to enable installation.
  • pipes are smaller in diameter than ductwork, it is typically easier to tape adjacent pieces or sections of pipe insulation in the conventional manner. Accordingly, there was no need to develop a method to eliminate the need to manually tape the circumferential seams between adjacent pieces or sections of pipe insulation.
  • the blanket which includes a strip of adhesive material adhered to the facing material along the length of the material near an edge thereof.
  • the adhesive is deposited on the facing material through the use of a pressure sensitive transfer tape.
  • the adhesive transfer tape comprising a release liner and an appropriate pressure
  • the sensitive adhesive adhered to one major face thereof is located on and extends along the factory fabricated flap which extends beyond the lateral edge of the mineral fiber blanket.
  • the tape is located on the same major surface of the facing material as is adhered to the mineral fiber blanket.
  • the transfer tape is positioned along the other lateral edge of the major surface of the duct wrap facing, and, when so positioned, is located on the major surface of the facing opposite that to which the mineral fiber blanket is adhered.
  • the release liner portion of the transfer tape is removed leaving a layer of adhesive on the facing in such a position as to facilitate the sealing of the lateral seams created during the installation by adherence to the factory fabricated flap of an adjacent piece or section of duct wrap.
  • Pressure sensitive transfer tape is well known to those familiar with various forms of
  • pressure sensitive tapes generally and is commercially available in roll form which can be applied to the facing of the duct wrap during the manufacturing process.
  • Such tapes comprise a release layer coated on one major surface thereof with a pressure sensitive adhesive material.
  • the adhesive material is transferred from the liner to the other material.
  • the pressure sensitive transfer tape is adhered as desired along a major surface of the facing material at or near a lateral edge thereof.
  • the adhesive utilized in conjunction with the transfer tape can be formulated to have flame retardant properties if so desired.
  • Another embodiment of the present invention includes the application of a double sided pressure sensitive tape at essentially the same location and in a similar manner as the transfer tape described above is utilized.
  • double sided pressure sensitive tapes are well known and include a web or substrate coated on both major surfaces thereof with an appropriate adhesive material.
  • a release liner is positioned on one major surface of the tape and the other surface is adhered to the facing material at a desired location. During installation of the duct wrap, the release liner is removed thereby exposing the underlying pressure sensitive adhesive layer which is then adhesively secured to a desired adjacent area of facing material.
  • Such double sided adhesive tapes are commercially available and are typically sold in roll form. Ideally such tapes are applied during manufacture of the duct wrap through an appropriate in-line means.
  • a double sided adhesive tape can be applied to either the factory fabricated flap or the opposite major surface of the facing along the other lateral edge of the duct wrap as described above for the release tape.
  • a further embodiment of the captioned invention includes the direct application of pressure sensitive adhesive to a desired portion of the facing material itself and subsequently positioning a release liner over the adhesive to prevent the adhesive from coming into contact with other portions of the product when the product is rolled for shipping, storage and handling.
  • the adhesive can either be applied along the factory fabricated flap or along the opposite major surface at or near the other lateral edge thereof.
  • Figure 1 shows a section of faced duct wrap insulation which includes a strip of
  • FIG. 2 shows another embodiment of the invention in which a strip of pressure sensitive transfer tape, double sided pressure sensitive tape, or adhesive material is located on the opposite major surface of the facing material at or near the opposite lateral edge of the facing material from that incorporating the factory fabricated flap.
  • Figure 3 shows a section of ductwork insulated in accordance,%kith the present invention.
  • Figure 1 shows a perspective view of a length of duct wrap insulation 5 made in accordance with the present invention and includes mineral fiber blanket 15 adhered to the inside surface of an appropriate facing material 25.
  • the blanket 15 and facing material 25 are adhered together with an appropriate adhesive material which may or may not include flame- retardant properties.
  • facing material 25 extends beyond one lateral edge of the mineral fiber blanket to form flap 10, on the inside surface of which is applied an appropriate adhesive material 20.
  • Flap 10 can be from I" to 6" wide, but in a preferred embodiment is approximately 2" wide.
  • Adhesive material 20 can be applied to flap 10 in the form of a pressure sensitive transfer tape, a double-sided pressure sensitive adhesive tape, or simply as a direct application of adhesive on the flap 10. Where a pressure sensitive transfer tape is utilized, the tape preferably comprises a release liner coated on one side thereof with an adhesive material. The tape can be applied to flap 10 along the length of the flap during the manufacturing process through an appropriate in-line method before the duct wrap is cut into segments such as that depicted in figure 1. The tape is applied to the flap with the adhesive coating on the inside surface of the flap.
  • the transfer tape can have a length and width which
  • the transfer tape can have a slightly longer width than flap 10 in order to facilitate removal of the release finer during installation of the product.
  • the release liner can be 2 1/4" wide, and is placed along the width of the flap such that there is 1/4" of exposed liner on one side of the flap.
  • the adhesive coating on the release liner need not extend the entire width of the liner.
  • the release liner is removed thereby exposing the adhesive on the inside surface of flap 10, which during installation is facing the ductwork 30 as shown in figure 3.
  • sections of duct wrap 40 and 50 are cut to an appropriate length to extend around the perimeter of the duct.
  • a section 45 of the insulation blanket 15 extending the entire width of the blanket is removed from one end of the duct wrap prior to installation leaving the facing material 25 intact to form a stapling and/or taping flap ("field fabricated flap" ) for overlapping the abutting opposite end of the section of duct wrap once it is positioned around the perimeter of the duct 30 in accordance with figure 3.
  • Figure 4 also shows flap 10 coated with adhesive material 20.
  • adhesive coated flap 10 of duct wrap section 50 overlaps the outer surface (facing outwardly from the duct in figure 3) of facing 25 of an adjacent piece or section of duct wrap 40 along the abutting lateral edge 60 thereof .
  • Adjacent pieces or sections of duct wrap are installed such that the flap of one piece or section of insulation overlaps the outer surface of the adj acent piece or section of insulation along the opposite lateral edge from that which includes the flap in a like fashion to that depicted in Figure 3.
  • the tape can be applied to flap 10 through an appropriate in-line method during the manufacturing process in similar fashion to the method used in the case of a transfer tape.
  • both pressure sensitive transfer tapes and double sided pressure sensitive adhesive tapes are available in roll form.
