Definitions

  • This invention relates to systems and methods for providing seals between adjacent building panels.
  • the invention has example applications for providing seals between prefabricated building panels.
  • Constructing a building is typically an extensive project involving significant amounts of time and/or resources (labour, energy, materials, etc.). Moreover, the carbon footprint of a building built using existing systems and methods can be large.
  • Reducing the amount of time and/or resources required to construct an energy efficient building can be desirable. Reducing the carbon footprint of a building can also be desirable.
  • One way to reduce the amount of time and/or resources required is to construct the building using prefabricated building panels. To provide effective insulating and/or weatherproofing characteristics for a building constructed with prefabricated building panels, adjacent panels must be properly sealed to meet performance specifications such as water permeability, air permeability, etc.
  • Another way to reduce the carbon footprint of a building is to install retrofit building panels to the exterior of the building. Retrofit building panels also must be properly sealed to meet performance specifications.
  • sealing materials which improve desired performance characteristics of a building constructed with prefabricated building panels or a retrofit building
  • sealing assemblies which improve desired performance characteristics of a building constructed with prefabricated building panels or a retrofit building.
  • Fig. 1 is a schematic perspective view of an exterior of a building.
  • Fig. 2A is a schematic perspective view of an exemplary sealing assembly provided between adjacent building panels which form part of the Fig. 1 building.
  • Fig. 2B is a schematic plan view of the Fig. 2A sealing assembly.
  • FIGs. 3A-D are schematic illustrations depicting various ways of providing the Fig. 2A sealing assembly between building panels.
  • FIG. 4 is a side view of an exemplary sealing assembly provided at an interface between adjacent vertical panels.
  • FIG. 5 is a top view of an exemplary sealing assembly provided at an interface between adjacent vertical panels.

  • Fig. 7 is a side view an example of providing the Fig. 2A sealing assembly between a vertical panel and a horizontal panel.
  • FIGS. 8A-J depict exemplary variations of the Fig. 2A sealing assembly.
  • FIG. 1 is a schematic perspective view of an exterior 4 of a building 2, such as a residential apartment building, a single story house, an institutional building, etc.
  • Exterior 4 may be a building wrap where building 2 is a retrofit building.
  • Exterior 4 of building 2 comprises multiple pre-fabricated building panels 6 which may be attached to building 2 and/or coupled together through suitable mechanical fasteners, adhesives, etc.
  • building panels 6 described herein may be broadly categorized as horizontal panels 6A and vertical panels 6B, 6C.
  • Horizontal panels 6A refer to building panels which are oriented to extend across a width and a depth of a building. Examples of horizontal panels 6A include: panels which are mounted on top of or form a roof of a building (i.e. roof panels), panels which are attached below or form the floor of a balcony, etc.
  • Vertical panels 6B, 6C refer to building panels which are oriented to extend along a height of a building. Vertical panels 6B, 6C are further categorized as either above grade building panels 6B or below grade building panels 6C. Above grade building panels 6B are located entirely above the grade level 1 of a building. Below grade building panels 6C are at least partially located below the grade level 1 of a building. Examples of above grade building panels 6B include panels which are mounted to or form the exterior walls of a building (i.e. wall panels). Examples of below grade building panels 6C include panels which are mounted to or form the foundation of a building (i.e. foundation panels).
  • FIG. 2A is a schematic perspective view of a sealing assembly 10 which is provided between adjacent building panels 6-1, 6-2 according to an example embodiment of the invention.
  • Building panels 6-1 , 6-2 may be an example of adjacent roof panels 6A, an example of adjacent wall panels 6B, an example of adjacent foundation panels 6C, etc.
  • Sealing assembly 10 is provided at a gap 7 between adjacent building panels 6-1 , 6-2.
  • opposed surfaces of adjacent building panels 6- 1 , 6-2 which define gap 7 are referred to herein as surfaces 8-1 , 8-2.
  • gap 7 is defined between an upper surface 8-1 of panel 6-1 and an undersurface 8-2 of panel 6-2.
  • Each surface 8-1 , 8-2 has a longer dimension corresponding to either the length or width of panel 6-1 , 6-2 and a shorter dimension corresponding to the thickness of panel 6-1 , 6-2.
  • building panels 6-1 , 6-2 depict adjacent wall panels 6B stacked on top of one another so the longer dimension of surfaces 8-1 , 8-2 corresponds to the width of building panels 6-1 , 6-2.
  • the longer dimension is identified by direction reference 101 and the shorter dimension is identified by direction reference 102.
  • direction reference 102 corresponds to the thickness of panel 6 extending between an exterior surface of panel 6 (i.e. a surface facing an exterior side 11 A) and a surface of building 2 on which panel 6 is mounted.
  • Direction 101 may also be referred to herein as longitudinal direction 101 as it denotes the direction that elongated components of assembly 10 described below extend longitudinally.
  • direction 102 extends perpendicular to direction 101 and may also be referred to herein as a transverse direction 102.
  • sealing assembly 10 comprises a first sealing member 12A transversely spaced from a second sealing member 12B in direction 102.
  • sealing members 12A, 12B provide a backing for applying sealants thereto.
  • First sealing member 12A and second sealing member 12B are typically arranged in spaced-apart parallel relation with the length of each sealing member 12A, 12B in alignment with dimension 101 , although this is not necessary.
  • sealing members 12 are cylindrically shaped. Where sealing members 12 are cylindrically shaped, the distance between first and second cylindrical sealing members 12A, 12B may be sized relative to their diameter (e.g.
  • first and second cylindrical sealing members 12A, 12B exceeds no more than, for example, about ten times their diameter). In some embodiments, the distance between first and second cylindrical sealing members 12A, 12B does not exceed twice the diameter of cylindrical sealing members 12. For example, first and second cylindrical sealing members 12A, 12B may have diameters which are in the range of about 1/2” to about 11/ . The distance between first and second cylindrical sealing members 12A, 12B may accordingly exceed no more than about 1 ” to about 3”.
  • Sealing members 12 are typically made of suitably compressible and suitably flexible materials such as closed cell polyurethane foam or the like. In some embodiments, sealing members 12 are made of suitably insulated materials which provide thermal insulation. In some embodiments, sealing members 12 are backer rods.
  • sealing members 12 are sized according to the size of gap 7 to fit snuggly between surfaces 8-1 , 8-2. In some embodiments, sealing members 12 are oversized relative to gap 7. For example, the diameter of sealing members 12 may be larger than the size of gap 7 such that sealing members 12 are compressed when inserted between surfaces 8-1 , 8-2. Compressing sealing members 12 between surfaces 8-1 , 8-2 can advantageously improve the air tightness and/or water tightness of sealing assembly 10. Compressing sealing members 12 between surfaces 8-1 , 8-2 can also advantageously help affix or otherwise minimize unwanted movement (e.g. sliding) of sealing members 12 between surfaces 8-1 , 8-2.
  • Sealing assembly 10 may also include a foam tape 14 for placement between surfaces 8-1 , 8-2 within gap 7.
  • foam tape 14 is transversely spaced apart from the second sealing member 12B in direction 102.
  • foam tape 14 is provided at a location which is more proximate to building 2 than sealing members 12 are to building 2.
  • foam tape 14 has a length in alignment with direction 101 .
  • foam tape 14 has the shape of a rectangular prism. Where foam tape 14 is rectangular shaped, foam tape 14 may be defined as having a length extending in direction 101 , a width extending in direction 102, and a thickness or height extending between surfaces 8-1 , 8-2.
  • Foam tape 14 is made of suitably compressible and/or suitably flexible materials such as polyvinyl chloride (PVC) or the like. Foam tape 14 is preferably closed-cell to help prevent air, water and/or vapor from passing through sealing assembly 10.
  • foam tape 14 is a compressible foam sealant such as polyurethane or neoprene.
  • foam tape 14 comprises compressible mineral fiber insulation.
  • foam tape 14 comprises a pre-compressed foam gasket such as EmsealTM expanding tape.
  • Foam tape 14 in its uncompressed state, must be thick enough to span gap 7 between building panels 6-1 , 6-2.
  • Foam tape 14 may be oversized relative to gap 7.
  • the thickness of foam tape 14 may be larger than the size of gap 7 such that foam tape 14 is compressed when provided between surfaces 8-1 , 8-2.
  • foam tape 14 When provided between surfaces 8-1 , 8-2, foam tape 14 may be compressed (along the direction of its thickness) by a percentage which is typically in the range of 20% to 60% to achieve air, water and/or vapor tightness between surfaces 8-1 , 8-2. In a currently preferred embodiment, foam tape 14 is compressed by about 50% when inserted between surfaces 8-1 , 8-2.
  • a foam tape 14 having an uncompressed thickness of about 3/4” may be compressed to a thickness of about 3/8” when it is provided between surfaces 8-1 , 8-2.
  • foam tape 14 is made of a material which expands to fit gap 7 after it is inserted between surfaces 8-1 , 8-2.
  • foam tape 14 is attached to a surface 8-1 of one of the adjacent building panels 6 (i.e. building panel 6-1) via adhesive.
  • foam tape 14 is compressed at the surface 8-2 of the other one of the adjacent building panels 6 (i.e. building panel 6-2).
  • Attaching foam tape 14 to surface 8-1 via adhesive can advantageously allow foam tape 14 to be preinstalled on building panel 6 such that foam tape 14 is automatically provided between panels 6-1 , 6-2 when panels 6-1 , 6-2 are coupled together (e.g. when panels 6-1 , 6-2 are positioned adjacent to each other). This can in some cases expedite the process of providing sealing assembly 10 between adjacent building panels 6-1 , 6-2.
  • the thickness of foam tape 14 is the same as the diameter of cylindrical sealing members 12. In some embodiments, the width of foam tape 14 is greater than the thickness or height of foam tape 14. In some embodiments, the distance between the second sealing member 12B and the rectangular foam tape 14 is smaller than the width of the rectangular foam tape 14. In some embodiments, the distance between the second sealing member 12B and the rectangular foam tape 14 is the same as the distance between first and second sealing members 12A, 12B.
  • Sealing assembly 10 may further comprise one or more layers of sealants 16 provided between surfaces 8-1 , 8-2 of adjacent building panels 6-1 , 6-2. As depicted in Fig. 2B, sealants 16 may be applied between surfaces 8-1 , 8-2 by applying sealants 16 against sealing members 12. This causes sealants 16 to spread around sealing members 12 and attach to surfaces 8-1 , 8-2. Sealing members 12 may exert a reaction force on sealants 16 when sealants 16 are pressed against sealing members 12. This can in some cases provide a better seal between surfaces 8-1 , 8-2.
  • sealants 16 are provided at an exterior side 11 A of each sealing member 12, but not at an interior side 11 B of sealing member 12.
  • exterior side 11 A is defined as the side which is more distal from building 2
  • interior side 11 B is defined as the side which is more proximate to building 2.
  • Sealants 16 extend in direction 101 along the length of sealing members 12.
  • sealants 16 extend along at least a substantial portion of the length of sealing members 12. In some embodiments sealants 16 may extend along the entire length of sealing members 12.
  • Sealants 16 preferably comprise materials suitable for providing airtight and/or watertight sealing between adjacent building panels 6-1 , 6-2 when sealants 16 are pressed against or otherwise applied to sealing members 12.
  • Sealants 16 typically comprise suitable weatherproofing materials such as polyurethane blends, acrylic blends, polyurethane caulking (e.g. SikaflexTM, MastersealTM NP1 , SpectrumTM), silicone based sealants, urethane based sealants, acrylic based sealants, polysulphide based sealants, polymer based sealants, silicone, etc.
  • Sealants 16 may optionally comprise fireproofing materials such as intumescent fire stop caulking or the like (e.g. DymonicTM caulking). Sealants 16 may optionally have adhesive qualities which can help adhere adjacent building panels 6-1 , 6-2 together.
  • one or more layers of sealants 16 may comprise a weep hole.
