Definitions

  • the present invention relates in general to skylights and the like, and is concerned, more particularly, with an improved technique for sealing the skylight about a roof or other building opening.
  • a skylight is conventionally secured to a roof or other appropriate part of the building with the use of a roofing mastic.
  • the roofing mastic is applied on the deck around the opening to provide a seal between the deck and the flange of the skylight.
  • the skylight is positioned over the opening and the flange is then pressed firmly into the mastic to provide a water tight seal.
  • the skylight flange is then nailed to the roof and additional mastic applied. Shingling is then completed about the entire skylight.
  • DE-A-2 209 543 discloses a fibreglass skylight having an integral flashing flange.
  • the skylight disclosed in the document suffers from the disadvantages described above because of the requirement for solvent welding, or bonding to effect a seal.
  • GB-A-2 132 672 describes a sealing technique for skylights which uses one or more nails for piercing the flange. This may have the effect of causing further leakage problems at the flange.
  • the sealing technique requires extra material in the form of flexible elements in order to effect at least a limited form of sealing.
  • Another object of the present invention is to provide a sealing technique as in accordance with the previous object, particularly adapted for sealing skylights and which is a dry seal technique.
  • a further object of the present invention is to provide an improved sealing technique as set forth hereinbefore and in which the sealing is provided by a dry seal, co-extruded element.
  • Still another object of the present invention is to provide a technique for sealing a skylight to a building about an opening in the building and without requiring the use of messy, expensive and time consuming roofing cements or mastics.
  • Still a further object of the present invention is to provide an improved skylight sealing technique that eliminates uncertainties when the unit is installed in the field due to inherent invariables associated with field installation.
  • Still another object of the present invention is to provide an improved skylight sealing technique that is particularly useful in skylight installations wherein skylights are butted closely together. Adjacent skylight flanges are adapted to overlap without the required use of caulking or mastic therebetween.
  • a further object of the present invention is to provide an improved skylight sealing technique in which the fastening of the skylight curb is carried out by separate means whereby the structural securing of the skylight curb frame does not rely upon a securing of the flange itself directly to the building.
  • Still a further object of the present invention is to provide an improved skylight sealing technique employing a co-extruded flexible flashing flange having a series of upwardly directed flow diverter ribs for assuring proper sealing and water deflection.
  • Another object of the present invention is to provide an improved skylight sealing technique in which the fastening of the skylight curb frame may be carried out by alternate means permitting securing either on the inside or outside of the curb frame.
  • Still another object of the present invention is to provide an improved skylight sealing technique employing a simplified means for securing the curb frame without requiring the use of a separate securing clip.
  • a further object of the present invention is to provide an improved skylight sealing technique that is particularly useful in skylight installations wherein skylights are butted closely together and in which instance, there is provided a common fastener for adjacent skylight curb frames.
  • the common fastener is preferably in the form of an elongated securing clip that extends between adjacent curb frames.
  • a skylight as defined in claim 1.
  • the bottom surface of the flashing flange is preferably substantially flat while the upper surface thereof has closely spaced upstanding ribs that form flow diverters so as to divert water away from the building.
  • the skylight curb frame itself is secured by separate clip means so that the securing of the curb frame does not have to rely upon a securing through the flashing flange itself.
  • the flashing flange itself is adapted to have no nails or other fasteners passing therethrough. This thus minimizes any chance for water entering the building about the skylight through the flashing flange membrane.
  • the flashing flange is simply lifted and the clip means is inserted into a slot in the curb frame.
  • the clip means is then secured by nails or other fasteners and the flashing flange is then placed thereover.
  • the shingles that are adapted to fit adjacent to the skylight are then placed over the co-extruded flexible flashing flange and it is preferred that in nailing these shingles that no nails be directed through the shingle and through the flashing flange.
  • the nailing of the shingles simply occurs outside of the co-extruded flexible flashing flange.
  • the aforementioned plurality of elongated spaced upstanding ribs are preferably provided in spaced sets with the spacing between sets of ribs being on the order of the width of each set. This has been found to provide enhanced flow diversion. Also, it is preferred to have a flashing cap extending upwardly from the flashing flange, generally of L-shape and adapted to receive the roofing shingles therein.
  • An alternate to the aforementioned securing clip is the provision of a peripheral rigid base extension from the curb frame through which a fastening means such as a roof nail may extend for the purpose of securing the curb frame. This securing is carried out beneath the sealing flange so as not to interfere therewith.
  • An integral sealing element is also provided and one element secured to one of the domes of the skylight and in the second embodiment integral with the curb frame itself.
  • the curb frame in an alternate embodiment may also be provided with a pair of base recesses for having the capability of receiving securing clips either on the inside or outside of the curb frame.
  • an improved flexible flange mulling concept in which skylights may be essentially supported in adjacent position.
  • the peripheral flexible flashing flange of each curb frame is disposed in an overlapping position.
  • the underlying flexible flashing flange may be trimmed to provide proper joining and there is provided a continuous seal between these overlapping flexible flashing flanges.
  • the continuous seal is preferably provided with a PVC glue or cement.
  • a common support is provided between the adjacent curb frames in the form of a continuous metallic hold down clip having opposite ends that are adapted to be received in slots of the respective spaced curb frames.
  • a fastener such as a nail may be employed to secure the clip to the building.
  • sealing ribs co-extruded with the curb frame for providing a seal between the end of each clip and the corresponding curb frame.
  • FIGS. 1-4 show one embodiment of the present invention. A preferred embodiment of the invention is illustrated in FIGS. 5-9 to be discussed in further detail hereinafter.
  • FIGS. 10-13 illustrate further details regarding the mulling of skylight units and the associated technique of sealing between flanges.
  • FIG. 1 is a cross-sectional view through one embodiment of the curb frame of the invention.
  • FIG. 1 also illustrates the co-extruder flexible flashing flange of the invention.
  • This integral peripheral flashing flange provides a much simpler alternative in the installation of skylights not requiring the use of roofing cement or step flashing kits.
  • This embodiment of the invention also offers the additional benefit and flexibility of offering an installer the convenience of arranging adjacent units together in a cluster by simply trimming and gluing overlapping flashing pieces so as to essentially form a one-piece, self-flashing skylight.
  • clusters of skylights are interconnected by more complex techniques requiring complex mulling kits or are made in custom factory built units.
  • the unit itself and the method of installation are extremely simple requiring fewer pieces and relatively simple instructions to be described in further detail hereinafter.
