Description

  • The invention relates generally to the field of building materials products and in particular insulating products for the external walls of buildings.
  • In building construction, the main barrier between the indoor environment and the unstable environment is made by several layers of different materials.
  • If combinations of materials capable of achieving thermal insulation and a moisture barrier have been developed, these faculties are, however, diminished when holes or discontinuities are present in the barrier material. These holes and discontinuities cause excessive heat loss (or heat seepage into air-conditioned structures) through air infiltration. Air entering the barrier contains moisture that is retained and causes mold and damage or affects durability.
  • One of the key tools to address these issues is the use of insulating blankets of habitats and other air and vapor retarders.
  • While these insulating blankets have reduced the amount of moisture penetrating inside buildings, the airtightness associated with these barriers has, however, reduced the drying capacity of the barrier materials.
  • In addition, the behavior of the barrier materials continues to depend on the quality of the execution of the installation of the materials. Spaces or discontinuities between adjacent sections insulating habitat cover will cause seepage.
  • Gypsum shells have recently been used outdoors in exterior insulation or finishing systems, with insulating layers (sometimes referred to as Exterior Insulation and Finish Systems (EIFS) or Exterior Insulation and Finish Systems). "). These systems are designed to accept polystyrene insulation bonded to a gypsum board with a glass facing, followed, for example, by applying a thin layer of stucco. Due to exposure to the elements, gypsum wallboard is often treated or impregnated with hydrophobic additives.
  • U.S. Patent No. 5644880, incorporated herein by reference, discloses an EIFS system in which the main components comprise a water-resistant gypsum board with a fibrous mat facing and an overlay finish material. The finishing material can take a multilayer or monolayer form. It may be placed in contiguity with said gypsum board or it may directly cover, or be directly attached to, one or more elements sandwiched between said gypsum board and said finishing material. The patent application DE 3546968 discloses a mineral fiber board which can be covered on a first main face by an outer coating permeable to water vapor and infiltration of outside air and on its second main face by an inner facing.
  • Improved construction products are desired. A method according to the present invention comprises providing an inorganic fiber insulating panel comprising glass fibers or rockwool fibers, slag wool fibers, ceramic fibers, resisting the penetration of liquid water and having first and second major surfaces, the lamination application of an outer facing material, resistant to air infiltration and liquid water penetration, to the first major surface of the insulation board, the material outer facing being permeable to the water vapor, and bonding an inner facing on the second major surface of the insulation board with an adhesive, so that the second main surface with the inner facing and the adhesive is strong to the penetration of liquid water, thereby forming a section of a unit outer building envelope product.
  • A product according to the invention comprises an insulating panel made of mineral fibers, comprising glass fibers or rock wool fibers, slag wool fibers, ceramic fibers, resistant to the penetration of liquid water and comprising first and second major surfaces; a water-vapor-permeable, water-infiltration-resistant, liquid-penetrating outer facing material laminated to the first major surface of the insulation board, and an inner lamination applied to the second main surface of the insulation board with an adhesive, so that the second main surface with the inner facing and the adhesive is resistant to the penetration of liquid water, thereby forming a section of a unit exterior building envelope product.

  • Other features relating to the invention, in particular structural or implementation may be found in or deduced from the US patent application no. 10/322 433, filed on December 19, 2002 , and U.S. Patent Application 10/322 433 filed on December 19, 2002 . These applications are incorporated herein in their entirety for reference.
  • With reference to the figure 1 , there is illustrated an insulating product 100 comprising a mineral fiber insulating panel 110 resistant to the penetration of liquid water, comprising first and second main surfaces. Product 100 is also referred to herein as Building Envelope Panel 100 or Exterior Panel System 100.
  • A cladding panel 130 capable of producing an air barrier or a rain screen is applied by lamination to the first surface of the insulation panel. The facing material 130 is permeable to water vapor. A water-repellent facing 120 is laminated to the second surface of the insulation board to form a unitary exterior building envelope product 100.
  • Preferred embodiments of the Exterior Board System ("EBS") 100 perform the following functions, in accordance with the general capabilities of a building envelope:
  1. (1) Resisting water / rain penetration - The EBS system is preferably used to protect the building from the weather so that work on the interior components of the building can start quickly, thus reducing duration and construction costs.
  2. (2) Accept Moisture Loads - EBS must accept moisture loads without deteriorating or damaging other building elements. The EBS system must allow moisture to escape to the outside.
  3. (3) Provide thermal insulation - The EBS system will provide immediate thermal insulation for the building as well as some of the final insulation set to meet the energy codes.
  4. (4) Act as a barrier to air infiltration - The EBS system will minimize air leakage through it and will be part of a barrier system to air infiltration.
  • The insulating product 100 is advantageously used as insulation in the exterior walls of buildings, such as commercial buildings with steel uprights. The insulating product 100 can however also be used in other construction applications.
  • The insulating panel 110 is preferably a non-cement board, such as an insulating board made of mineral fibers, preferably comprising mineral fibers such as glass fibers, rock wool fibers, slag wool fibers, organic fibers, ceramic fibers (eg alumina), silica or basalt fibers bonded with resin to form a rigid or semi-rigid panel. For example, suitable mineral fiber insulation boards are marketed by CertainTeed Corp. from Valley Forge, Pennsylvania.
  • The mineral fiber insulation board 110 may have a density of from about 2 pounds per cubic foot (PCF) to about 8 PCF (1 PCF = 16.02 kg / m 3 ). Preferably, the density of insulating board 110 is between about 2.5 PCF and about 4.0 PCF and more preferably, the density may be about 3 PCF. An example of a panel material is a glass fiber material having a binder content of from about 6% to about 17%, preferably from about 14% to about 15%. A water repellent may be mixed with the binder or injected into the binder prior to spraying the binder onto the glass fiber. Examples of water repellents may be DC347, DC346 and DC1581 available from Dow Corning of Midland, Michigan. The water repellent may form a fraction of the total panel content of between about 0.1% and about 2%. Some embodiments comprise about 0.2% water repellant. The water repellent may also be used to treat the siding 120 applied by lamination on the panel.
  • The hydrophobic agent is preferably introduced into the binder shortly before spraying. The silicone can be added to the rinse water used as dilution water shortly before spraying the fibers.
  • The hydrophobic silicone agent may also be applied to the mineral fibers separately from the binder in an emulsion or an aqueous solution used for cooling the hot mineral fibers in a fiberizing and shaping section of mineral fiber insulating panels before the application of the binder.
  • Preferred insulating materials can be selected, in terms of water resistance, using two test methods in accordance with ASTM Standard 473-00, Test Methods for Physical Testing. Gypsum Board Products. These two test methods are:
    1. 1) The Water Resistance of Gypsum Panel Products Water Repellent Treated in the Heart, and
    2. 2) Surface Water Resistance of Gypsum Board Products with Water-Resistant Surfaces.
  • In the ASTM C473 Surface Water Resistance Cobb test, preferred materials absorb about 40 grams or less of water in 10 minutes, preferably about 1.26 grams or less. In the ASTM C473 Core Water Resistance Cobb test, the preferred materials absorb about 1050 grams or less of water per square foot (1 square foot = 0.093 m 2 ) in 120 minutes, preferably about 60 grams. or less. Values above the core water resistance test correspond to a water absorption of less than 400% of the weight of insulation, preferably 74% or less. The surface water resistance test is carried out on the surface 120 of the insulating panel.
  • In other embodiments, the insulating board 110 has a fibrous mineral matrix (e.g., glass fiber) in which a phosphate-containing compound ("PCC", e.g., inorganic phosphate salt) is incorporated therein and a refractory mineral filler ("RMF", eg alumina or aluminum sulphate) to improve fire resistance. Preferably, the PCC is an inorganic phosphate salt. Suitable salts include monoammonium phosphate, diammonium phosphate, ammonium polyphosphate, monocalcium phosphate, dicalcium phosphate, aluminum phosphate, monosodium dihydrogen phosphate, tetrasodium pyrophosphate, hexametaphosphate of sodium, sodium tripolyphosphate, tetrapotassium pyrophosphate and potassium tripolyphosphate. Mixtures of several PCCs (eg mixtures of mono and diammonium phosphates) can also be used. PCC hydrates (eg, monoammonium phosphate dihydrate) may be used, in which case the water of hydration will be ignored to determine the content (eg,% by weight) of the PCC in the product. insulating. Although not essential, it is preferred that the RMF be relatively biologically inert, so that human contact with the flame retardant insulation product is not particularly dangerous or irritating. Suitable RMFs include alumina, calcium oxide, magnesium oxide, titania, zirconia, and aluminum sulfate. Insulating fiberglass products containing mono phosphate and / or diammonium as PCC and alumina or aluminum sulfate as RMF have been found desirable. The hydrated forms of FMRs (eg, aluminum sulfate hydrate) may be used, in which case the water of hydration will be ignored to determine the content (eg,% by weight) of the RMF in the insulating product. A more detailed description of a fire-resistant insulating material can be found in U.S. 10/831 843, filed on April 26, 2004 which is incorporated herein in its entirety by way of reference.
  • Table 1 lists the results of water penetration (grams of water that penetrated through the tested surface) for several insulating panel materials that could be used in insulation board 110, based on a Cobb test in accordance with ASTM 473C. The tests indicated the possibility of a minimum penetration of 0.01 gram in ten minutes to a maximum penetration of 250 grams in ten minutes.

Other mat materials with similar or higher hydrophobicity levels may be used instead. By way of example, materials may comprise randomly dispersed fiberglass mats to form a web in a wet laying process, bonded in a system of acrylic or other resins, and post-processing. treated with a fluorocarbon coating providing the desired level of hydrophobicity.
  • In one embodiment, the cladding 120 comprises a nonwoven glass fiber mat having a weight of less than 53.7 g / m 2 (1.1 lb / 100 ft 2 ) and, more preferably, less than 48.81 g / m 2 (1.0 lb / 100 ft 2 ). In one exemplary embodiment, the nonwoven glass fiber mat is Manniglas® 1807 mat, reference 27, having a target weight of 42.3 g / m 2 (0.87 lb / 100 ft 2 ) and a maximum weight of 47.5 g / m 2 (0.97 lb / 100 ft 2 ), available from Lydall Inc., mat Manniglas® 1803WHB, reference 23, having a target weight of 39.1 g / m 2 (0.80 lb / 100 ft 2 ) and a maximum weight of 43.9 g / m 2 (0.90 lb / 100 ft 2 ), also available from Lydall Inc. or a mat whose weight is between them. These nonwoven examples incorporate integral water repellency. In one exemplary embodiment, the nonwoven is combined, as by saturation, with a water repellent comprising a fluorinated polymer, such as a fluorinated acrylic, a fluoropolymer or a fluorocarbon, silicone, wax, oil, wax-asphalt emulsions, acrylics, other emulsions, latices, polyvinyl acetates, etc. The weights reflect the combined weight of the coating and mat. In this embodiment, the desired hydrophobicity can be achieved without the use of water repellant added to the binder of the insulation board or adhesive to bond the nonwoven to the conduit panel.
  • Alternatively, the inner facing 120 may be a woven fabric. Examples of woven glass fabrics may be a square pattern comprising 10 x 10 threads per inch, such as PermaGlas-Mesh resin coated glass fiber cloth 10 x 10 or PermaGlas-Mesh resin coated woven glass cloth 20 x 20, manufactured by Saint-Gobain Technical Fabrics of St. Catharines, Ontario, Canada. Both fabrics have a tensile strength of 85 pounds per inch of width in the fiber direction (MD) and in the cross-fiber direction (CD). Alternatively, the CHIL-GLAS glass fiber reinforcement mesh, reference 10, available from Childers or the woven glass available from Carolina Narrow Fabric may be used.
  • Needled, woven, knitted and composite materials can also be used because of their remarkable strength / weight ratio. The inner facing 120 may contain fibers and filaments of organic and inorganic materials. Examples include glass-containing fibers, olefin (such as polyethylene, polystyrene and polypropylene), Kevlar®, graphite, rayon, polyester, carbon, ceramic fibers or combinations thereof such as glass-polyester blends or Twintex® glass-olefin composite, available from St. Gobain Vétrotex, France. Among these types of fibers and filaments, glass-based compositions are desirable because of their fire resistance, low cost, and high mechanical strength. The four main lenses used are strong alkalis (A glass or AR glass) useful in engine and cement applications, such as in tile racks, electric quality glass (E glass), chemical resistant modified E glass (ECR glass) and a high-resistance glass (S-glass).
  • Resistance (to liquid water) of the inner surface may result from the process of laminating a non-liquid water resistant fabric laminated to a water-resistant mineral fiber board with the aid of an adhesive containing a hydrophobic additive. The surface of the laminated panel thus obtained is resistant to liquid water even if the fabric itself may or may not be resistant to liquid water. For example, if a loosely and open-armored fabric 120 (e.g., 10 x 10) is used, the spaces between the fibers of the fabric 120 are open, and the resistance to water penetration of the surface insulation with adhesive and fabric would be provided by the strength of the insulation and / or the resistance of the adhesive to the penetration of liquid water.
  • Combinations of fiberglass mats, canvas, chopped fibers and woven or knitted filaments or roving may also be used for inner cladding layer 120. The appropriate weights of fiberglass mat (usually a chopped strand mat) and woven strand filaments or loose staple fibers are either bonded together with a chemical binder or mechanically knitted, needled or sewn together. A suitable combination would be a fiberglass and / or resin fiber mat or fabric covered with a layer of cut glass or resin fibers and then needled or sewn to reduce porosity.
  • In some embodiments, the inner facing 120 may optionally be a variable type vapor retarder (such as the "MEMBRAIN " smart vapor retarder marketed by CertainTeed Corp. of Valley Forge, Pennsylvania). An intelligent vapor retarder modifies its permeability according to the ambient humidity.
  • Table 3 lists several preferred vapor retarder combinations for the inner surface 120, for embodiments with an ASTM E84 test "Standard Test Method - Superficial Combustion Characteristics of Construction Materials": propagation index of the flame / flue gas maximum 25/50.

  • In addition to the facings described above, the inner facing may be any of those described in US Patent Nos. 5718785, 5644880 or 4647496, which are hereby incorporated by reference.
  • If it is preferable that the material of the inner facing is resistant to the penetration of liquid water, other facings may however also be used. If the facing material is not resistant to the penetration of liquid water, or if it has openings which would allow the penetration of liquid water, the resistance to penetration of liquid water for the panel 100 would then be ensured. by means of an insulating material resistant to penetration of water 110 and / or an adhesive resistant to penetration of water.
  • In some embodiments, the mineral fiber insulation board has a male rabbet edge 150 and a female rabbet edge 140.
  • In some embodiments, the facing material 130 has a sealing skirt 160. The sealing skirt 160 preferably extends to the end of the male rabbet edge 150 (and, preferably, the facing 130 extends in the other direction to the end of the female rabbet edge 140). The sealing skirt 160 covers the female rabbet edge 140 conjugated with an adjacent section 100 of the construction material, as best shown in FIG. figure 2 . In this way, the sealing skirt 160 ensures that the joint of the facing 130 does not coincide with an air gap between the male rabbet edge 150 and the female rabbet edge 140 conjugated.
  • In other embodiments (not shown), a sealing skirt may extend beyond the end of the female rabbet edge 140.
  • A double-sided tape 170 (or a layer of pressure-sensitive adhesive) may optionally be adhered to an inner surface of the sealing skirt 160. It will be appreciated by those skilled in the art that the drawings are not to scale, and that the thicknesses of the skirt 160 and ribbon 170 are exaggerated for reasons of clarity. Suitable double-sided tape-ribbons include, but are not limited to: Venture Tape 1163H NS and 1163 / ms74 manufactured by Venture Tape of Rockland, Mass., And 3M 9500PC, 9490LE, 9690 manufactured by Minnesota Mining and Manufacturing Co. of St. Paul, Minnesota.
  • The product example 100 may be incorporated in an exterior building wall 200, as illustrated by FIG. figure 2 . The figure 2 is a lateral cross-sectional view of a portion of an exterior wall 200. It will be understood that the wall 200 may comprise any number of panels extending up or down to obtain any desired height, and to the left and to the right to obtain any desired width; the two panels 100 illustrated in wall 200 of the figure 2 are an arbitrary example only to simplify the illustration.
  • The wall 200 comprises a plurality of framing members 202. A layer of at least one panel 100 of a unit building envelope material is mounted on the outer side of the framing members 200. example, the figure 2 illustrates a plurality of fasteners 208 that secure the panels 100 to the frame members 202. In other embodiments, an "X-Seal " anchor device marketed by Hohmann and Barnard, Inc. Hauppauge, New York, can be used (described below with reference to the figure 8 ) instead of the fasteners 206 and 208 for attaching the illustrated components to the figure 2 (That is, to attach the outer layer 204 to the frame members 202). The insulating panel 110 is not a carrier product. The building envelope material 100 may be of the type described above with reference to the figure 1 , in particular: a mineral fiber insulating panel 110 resistant to the penetration of liquid water and comprising inner and outer main surfaces, a facing material 130 capable of providing an air and moisture barrier, applied by lamination to the outer surface insulation board (the facing material being permeable to water vapor), and a siding 120 resistant to the penetration of liquid water, laminated to the inner surface of the insulating board with an adhesive containing one or more hydrophobic additives, the inner surface facing the framing members.
  • An outer layer 204 is provided on the outer side of the building envelope material. The outer layer 204 may be, for example, concrete masonry, ceramic tile, glass, treated wood panel, cladding, shingles, bricks, stucco or stone, or the like. The outer layer 204 is attached to the frame members 202 by means of an attachment device 206 which passes through the section 100 of the building envelope product, the facing material 130 facing the outer layer 204 Although the figure 2 illustrates bolts 206 as fasteners, a choice of fasteners and fasteners may be used. Those skilled in the art will appreciate that the preferred type of fastener for any given wall will depend on the material of the frame members 202 and building exterior layer material 204. The building envelope panel 100 does not carry the structure and the fastening devices 206 thus simply pass through the panels 100.
  • In one example, a stone facade 204 is attached to the steel stud structure 202 using a wire tie 206 which is screwed into the steel frame 202 through the panel 100.
  • The figure 2 illustrates how the panel example 100 can simplify installation and reduce labor. The panel 100 forms a single product capable of replacing two to four different building materials that were separately applied in the prior art. There is no need to separately install each of the following building materials: (1) water-repellent air barrier, (2) insulation, (3) vapor-permeable air / rain barrier , and (4) a sealing tape. If the figure 2 illustrates the exterior building layer 204 in direct contact with the exterior cladding 130, in other embodiments (not shown), there is an air gap between the exterior cladding 130 and the building exterior layer 204.
  • As illustrated by figure 2 , the male rabbet edge 150 engages the female rabbet edge 140, and the skirt 160 at the bottom of the top panel 100 overlies the outer side of the female rabbet edge 140. The double-sided tape or adhesive 170 forms a seal between the two panels 100. The rabbet construction thus ensures the absence of a continuous air gap between two adjacent panels.
  • Although the figures illustrate a panel with male and female rabbet edges only in the bottom and top, respectively, of panel 100, additional male and female rabbet edges
  • (not shown) may be provided on the left and right sides of the panel. Providing rebated edges on all four sides of the panel makes it easier to assemble the panels and seal the four sides of a given panel, thereby improving the seal and reducing the wear on the panel. lumber. In another embodiment (not shown), there are no rebated edges, but the facing has a flange on one side only. In yet another embodiment, the cladding has flanges on two sides - a horizontal and a vertical.
  • The interior surface (without any improvement) has a maximum flame spread / flue gas emission rating of 25/50 in the fire hazard classification according to ASTM test method E84. In some embodiments, the product may have improved fire resistance.
  • The figure 3 illustrates another variant of the EBS 300 panel. The elements of the figure 3 identical to those illustrated and described above with reference to the figure 1 have the same numerical references plus 200. These include the panel 300, the insulation board 310, the water-repellent interior facing 320, the air and exterior rain barrier 330, the female rebate edge 340, the male rabbet 350, skirt 360 and tape or adhesive 370. These elements will not be described again. The panel 300 further comprises an improved fire-resistant "face" 380, possibly provided on the side of the insulator 310 which is facing the interior of the building. The fire resistance is provided by a coating or cladding 380 applied to the insulation 310, over the inner cladding 320. In some embodiments, the improved fire-resistant coating is applied directly to the insulation 310, without any 320 facing layer. These materials or other fire-resistant sidings or membranes whose fire resistance is provided by intumescent agents and / or vermiculite can be used.
  • In another embodiment of a flame retardancy process, a mixture comprising vermiculite and expandable graphite is dispersed in water, and the dispersion is coated on the glass fiber substrate 310, and dried. This process is described in detail in U.S. Patent Application Serial No. 10 / 322,433, filed December 19, 2002, incorporated herein by reference.
  • Some particular examples of fire resistant facing materials 380 that can be used to improve fire resistance include:
    1. 1) "VEXTRA®" vermiculite-coated woven glass fabrics available from Auburn Manufacturing Inc. of Mechanic Falls, Maine;
    2. 2) "FYREROC®" inorganic-coated flame retardants available from Goodrich Corporation, Polymer Construction Products Division, Jacksonville, Florida. These products can incorporate the following fire-resistant inorganic coating substrates: carbon filament woven fabric, steel wool, nonwoven glass three-layer laminate, woven steel fibers and nonwoven glass .

  • In some embodiments, the surface of the panel 100 or 300 closest to the installer (generally, the outer layer 130) is provided with vertical lines 400 printed every inch (or at another chosen interval) to serve as benchmarks. for guiding the installation of the panel 100 or 300 on the steel uprights 202. All screws (or other fasteners) 402 driven through the panel 100 or 300 must enter a steel upright 202 under the panel. Most of the steel stud 202 is concealed by the panel 100, 300 (as shown in FIG. figure 4 ) when the installer places the panel against the studs. However, the top of the amount 202 is visible, and the installer can identify the position of the steel uprights 202 relative to the pattern of vertical lines printed on the face of the panel. For example, if the amounts are located at the marks 4, 28, 52, 76, the installer can place his fastening screws 402 at these vertical lines 400 in the middle, at the top and bottom of the panel 100, 300. Moreover, when the panels are applied so that the lines are horizontal, they serve as spacing mark. This mark indicates the fastener separation position required by the manufacturer or architect (for example, 12 inches center-to-center, or every 12 inches). This will facilitate also the installation process, as long as the installer can count the lines once, start the installation and follow the same line throughout the installation.
  • Alternatively, these lines may be of different but repeating colors (e.g., 6 or 12 different colors that repeat in the same manner). This would provide the installer with a line that is easy to identify and follow for the installation process (that is, if the installer starts on the red line, he knows he has to follow the red line for the rest of this line fastenings).
    • The figure 5 illustrates another example in which vertical lines 400 and horizontal lines 502 are provided to form a grid pattern. Regardless of the orientation of the panel, one group of lines will be parallel to the uprights 202, and the other group of lines may be used to space the anchors (or other fasteners).
    • The figure 6 illustrates another exterior wall 600, namely a variant of the wall 200 of the figure 2 . Similar elements are identified by similar numerical references. The elements described above with reference to the figure 2 will not be mentioned again. The wall 600 includes steel studs 202, an outer gypsum layer 602 held in place by fasteners 604, a panel 100, anchors (or other fasteners 208) to the wall and an exterior stone veneer (or other outer layer of building) 204.
  • In some embodiments, the inner facing 120 of the figure 6 may optionally be a variable type 120 vapor retarder (such as the "MEMBRAIN " smart vapor retarder marketed by CertainTeed Corp. of Valley Forge, Pennsylvania). In this way, if excess moisture accumulates in the gypsum (gypsum is relatively permeable to water vapor), the use of an intelligent vapor retarder for cladding 120 would allow moisture to escape to the outside of the building.
  • In some embodiments, the fasteners 206 are not necessary, since the panel system 110 includes an attachment to the outer wall 204, e.g. tie rods for brick.
  • The figure 8 is a cross-sectional view of a wall 800, namely another variant of the wall of the figure 2 . To the figure 8 an air void is provided between the panel 100 and the outer building layer 204. The outer building layer 204 may be "freestanding" in the vertical direction (eg brick) and may possibly require only anchors 806 in the horizontal direction for tensile and compressive strength. In one embodiment, the anchor 806 may be an "X-Seal " anchor marketed by Hohmann and Barnard, Inc. of Hauppauge, New York. The anchor device "X-Seal " is advantageously used for the insulating panel 110 in that it transfers the load from the outer wall to the steel upright 202.
  • If the invention has been described in the context of exemplary embodiments, however, it is not limited thereto. In fact, the appended claims will be interpreted in the broad sense, which will incorporate other variants and embodiments of the invention that the skilled person can achieve without departing from the framework and the large choice of equivalents of the invention.
