Definitions

  • This invention relates to an elongate air sealing member made from a flexible, compressible, water repellant material having, inter alia , thermal insulating properties. More particularly, this invention relates to an auxiliary insulating profile for installation in a cavity wall.
  • insulated, cavity wall construction In certain types of building construction, known as insulated, cavity wall construction, it is customary to have a construction comprising an outer wall, an air gap or cavity that is eventually vented, and an inner wall. Such a construction usually includes insulation boards or insulation materials applied to the inside cavity wall in such a manner that a venting space remains between the insulating boards and the outer wall. It has been shown that natural convection, meaning thermal air circulation, causes substantial heat losses around insulation layers and/or insulation boards, as compared to calculated theoretical values.
  • the inner wall is normally not smooth at its cavity side, i.e. there are projecting cement residues and brick dimensional tolerances which prevent insulating boards from coming to rest perfectly against the inner-wall. Furthermore, the top and bottom edges of insulation layers are normally not sealed in an airtight manner with other building parts. Therefore, it is clear that in order to obtain proper thermal insulation, it is necessary to take extra precautions and work very accurately, which is time-­consuming and hence an expensive way of building an insulated, cavity wall construction.
  • the auxiliary member comprises essentially an L-shaped cross section of a flexible, compressible, water repellant material having thermal insulation properties. Such a profile is adapted to fit against the butt edge of an insulating board.
  • Other types of L-shaped profiles can be employed to accommodate insulating boards having tongue-and-groove edges, or ship-lapped edges.
  • L-shaped profiles containing various other minor modifications can also be employed to accommodate the edges of specially formed insulating boards, and these are contemplated as falling within the scope of the present invention.
  • any flexible, compressible, water repellant material having thermal insulating properties can be employed in the practice of this invention.
  • Such materials include, for example, synthetic foams made from polyethylene, polypropylene, polyurethane, ethylene vinyl acetate, polyvinyl chloride, polystyrene and the like, both extruded and expanded.
  • synthetic foams made from polyethylene, polypropylene, polyurethane, ethylene vinyl acetate, polyvinyl chloride, polystyrene and the like, both extruded and expanded.
  • elastic, closed-cell, crosslinked and non-crosslinked polyolefin foams are employed.
  • cavity sealing profiles comprising closed-cell, non-crosslinked polyethylene foam or mixtures containing such foams are utilized in the present invention.
  • These materials have very good thermal insulating properties, are not susceptible to hydrolysis and absorb practically no water.
  • polyethylene foam materials are resilient and can absorb the tensile and compressive stresses arising from temperature fluctuations or load pressures. Due to their resilience they are able to deform under stress and pressure and thereby fit tightly into a cavity wall without cracking.
  • cavity sealing profiles made from such materials form a tight compression fit within the cavity that effectively prevents any heat losses from occurring via thermal convection.
  • the desired profiles can be milled to shape from block foam, molded to shape, or extruded to shape through special dies.
  • the cavity sealing profile is adapted to be placed in the cavity of the wall in such a manner that the outer longitudinal face of the vertical member of the L-shaped profile is adjacent to the inner surface of the exterior wall, while the longitudinal edge of the horizontal limb of the L-shaped cavity sealing profile is adjacent to the inner cavity surface of the interior wall.
  • auxiliary profile is in the construction of the cavity wall itself. In some countries, both inner and outer cavity walls are progressively constructed at the same time. By seating the auxiliary profile at the base of the cavity of the cavity wall, it forms a spacer between the inner and outer walls, thereby providing and maintaining a proper cavity width. At the same time, the auxiliary profile helps to prevent cold bridges from occurring at connections between insulation surfaces and other construction parts. Furthermore, as a construction aid, once the longitudinal surface of the horizontal limb of the cavity sealing profile is plumb and level, insulation boards subsequently added thereto will also automatically be level.
  • a second cavity sealing profile is attached which is in opposition to the base cavity sealing profile, thereby effectively sealing all air leaks both at the bottom and at the top of the cavity.
  • additional cavity sealing profiles can be installed at vertical corners and around wall openings, such as doors and windows.
  • the cavity sealing profiles of the present invention can serve to discharge any condensate or rain water that may occur in the cavity between the insulating layer and the inner surface of the exterior wall.
  • the top surface of the cavity sealing profile is sloped downwardly to the exterior wall.
  • the inclined top surface conducts any water or condensate towards the direction of the external wall. The water and condensate can be easily discharged via openings provided near the lowest point of the inclined top surface leading to the exterior of the outer wall.
  • a moisture-proof, tear resistant, flexible film can be employed which serves as a condensate or water barrier.
  • a film is made to adhere to the sloping surface of the cavity sealing profile.
  • the top edge of this film is secured to the exterior surface of the insulation board, whereas the bottom edge of this film leads to the outside of the exterior wall via a horizontal joint in the outer wall.
  • Such a film effectively serves as a water impermeable barrier and conduit to the exterior surface of the outer wall for any rainwater or condensate that finds its way inside the cavity wall.
  • the top of this film can be conveniently secured to the exterior surface of the insulation boards by passing the film through a horizontal joint of the insulation layer in such a manner as not to disturb the air tightness of the joint.
  • Any type of moisture proof film can be utilized in connection with this invention. Due to the hard usage to which such a film is subjected during construction, it is desirable to employ a film of sufficient thickness so as to be tear and puncture resistant, but which still retains its flexibility. Cast or blown films made from linear low density polyethylene resins are particularly useful in the practice of this invention. They exhibit exceptional tear, toughness and puncture resistant properties and are completely water resistant. The film can be so attached to the auxiliary profile that it allows a horizontal overlap which can be either a loose-laid overlap or which can be sealed together at the job site.
  • FIG. 1 One embodiment of an elongate cavity sealing profile (1) is shown in Figure 1, which has a substantially L-shaped cross section, and which is made from a flexible, compressible material having thermal insulating properties.
  • the free end of the vertical limb (2) of the L-shaped cavity sealing profile (1) has a top surface (3) extending obliquely downwards from its inner longitudinal face (4) to the direction of its outer longitudinal face (5).
  • a moisture-resistant, film material (6) may be fixed to the top sloping surface (3), said film being of sufficient length so as to substantially extend beyond the top and bottom edges of the sloping surface (3).
  • the cavity sealing profile (1) is adapted to be a compression fit in the base of the cavity (7) of a cavity wall (9,10).
  • the bottom longitudinal face (11) of said profile rests on the foundation (8) or the base of the cavity (7), while the outer longitudinal face (5) is adjacent to the inner surface of the exterior wall (10).
  • the longitudinal edge (13) of the horizontal limb (12) rests adjacent to the inner surface of the interior wall (9).
  • a part of an insulating board (14) is adapted to be confined therein. It is clear that the sealing member (1) should be of such a length as to seal the entire length of the cavity wall.
  • the inclined top surface (3) of the cavity sealing profile (1) is designed so as to collect any rain water or moisture condensate present in the cavity (7), and discharge it to the outside of the exterior wall (10).
  • the sealing profile (1) is positioned in such a manner that the lowest point of the top surface (3) is flush with a horizontal joint (15) formed by two rows of bricks in the exterior wall (10).
  • the moisture-proof, tear resistant, flexible film (6) is affixed to the top surface (3) of the cavity sealing profile (1).
  • the top edge of this film can be readily held in place by passing it through a joint (20) formed between two insulation boards (14), care being taken not to disturb the air tightness of the joint.
  • the lower edge of the film can be sloped downward and led to the exterior via the horizontal joint (15).
  • the top of the cavity wall can be enclosed by reversing the cavity sealing profile so that the longitudinal face (11) of said profile (1) is adjacent to the ceiling (16).
  • Figures 3 and 4 show a vertical and horizontal cross-section of a cavity wall adjacent to a window or door opening, and shows how the cavity sealing profile (1) can be mounted in such a case.
  • Figure 3 shows the use of a course of brick or stone laid on edge (17), and the placement of the sealing profile (1) at the appropriate height against the inner face of said course of brick or stone.
  • edge (17) is a lintel or ornamental supporting structure of natural stone, having a larger vertical dimension than the outer longitudinal face (5) of the cavity sealing profile.
  • the joints (15) between the lintel and superposed brick function as an outlet channel for any moisture or water the cavity may receive.
  • the cavity formed between the frame (18) and the bottom longitudinal face (11) of the sealing member (1) can be filled with an insulation member (14) and then with an expandable foam or soft insulation material (19).
  • an insulation member (14) and then with an expandable foam or soft insulation material (19).
  • the cavity sealing profile can be placed against the frame (18) without objection, since its positioning near a joint is not necessary in the vertical plane.
  • Figure 5 shows an embodiment of how a cavity sealing profile (1) can function as a cavity sealer in the situation where the external walls are set at right angles to each other. Such a positioning of the sealing profile results in effectively sealing any gaps created by improperly fitting insulating boards. Since even small gaps of one or two millimeters can create thermal convection with resulting heat loss, the use of a cavity sealing profile to seal a corner joint is a further advantage of the present invention.
  • Figures 6 and 7 show two cross sectional variations of the sealing profile (1).
  • the ridged horizontal limb ensures that the edges of the insulation board (14) having a complementary profile, fit snugly and remain air tight.
  • the fact that the cavity sealing profile can be slightly deformed when the edge of the insulation board is pressed against the L-shaped surface of the cavity sealing profile ensures a tight fit. The result is that excellent sealing is obtained and no undesirable air circulation or thermal convection occurs between the inner surface of the interior wall and the insulation boards.
  • the sealing member can be used between any two spaced-apart walls to prevent undesirable air circulation or convection from occurring.
