Definitions

  • the present disclosure is related to fenestration systems and, more particularly, to an improved thermal break profile for mating with profile extrusions.
  • the window and door industry is sometimes referred to as the "fenestration" industry, and common fenestration systems include, but are not limited to, window assemblies, door assemblies, storefront framing, curtain walls, window walls, sliding doors, fixed vents, glazed roofing assemblies, any combination thereof, and others.
  • Aesthetic considerations play an important part in the architectural design of fenestration systems, but the overall energy efficiency of a building an increasingly important factor in architectural design. Consequently, there is a continued demand for building features and methods of construction that improve energy efficiency.
  • thermal separators may be made of materials that exhibit low thermal conductivity. Examples of such fenestration systems with thermal separators are shown in US4338753 A , EP2055883 A2 and EP0943775 A1 .
  • Embodiments disclosed herein include a profile for a fenestration system where the profile includes a first member and a second member offset from the first member and thereby defining an inner space therebetween, and a thermal break arranged within the inner space and extending between the first and second members.
  • the thermal break is operatively coupled to the first member at a thermal break interconnection that includes a tab extending laterally from a body of the thermal break and including a head extending from the body and a stem extending from the head, and a channel defined by upper and lower flanges of the first member, the channel providing a first chamber sized to receive the head, and a second chamber extending from the first chamber and sized to receive the stem.
  • the head exhibits a larger cross-section than the stem, and a size of the first chamber is larger than a size of the second chamber, and the thermal break is temporarily secured to the channel by advancing the tab into the channel, and permanently secured to the channel by crimping the upper and lower flanges against the tab.
  • the outer surface of the stem comprises grooves and the inner surface of the second chamber is in contact with the stem.
  • the channel transitions between the first and second chambers at a lateral protrusion defined on one or both of the upper and lower flanges, and wherein the head engages the lateral protrusion when advancing the tab into the channel.
  • the thermal break interconnection further includes one or more grooves defined on at least one of the tab and the channel.
  • the one or more grooves comprise one or more second grooves defined on an inner surface of the second chamber.
  • the one or more grooves comprise one or more first grooves defined on an outer surface of the head, and one or more second grooves defined on an inner surface of the first chamber.
  • the thermal break interconnection further includes an adhesive applied at an interface between the tab and the channel.
  • the thermal break interconnection further includes one or more grooves defined on at least one of the tab and the channel, and wherein the adhesive flows into the one or more grooves to strengthen the thermal break interconnection.
  • the fenestration system comprises a commercial or residential fenestration system selected from the group consisting of a window, a door, storefront framing, a curtain wall assembly, a window wall, a conservatory, a balcony, a glazed roofing system, a sliding door, a sliding window, a window assembly, a door assembly, a fixed vent, and any combination thereof.
  • Embodiments disclosed herein but not covered by the subject-matter of the claims may further include a thermal break for a profile of a fenestration system, the thermal break includes a body having opposing first and second ends and extending along a centerline, and a tab provided at each end and extending laterally from the body along the centerline, and the tab including a head extending from the body, and a stem extending from the head.
  • the head exhibits a larger cross-section than the stem, and the head and the stem are sized to be received and secured within a channel provided by the profile of the fenestration system, the channel defining a first chamber sized to receive the head and a second chamber sized to receive the stem.
  • Embodiments disclosed herein may also include a method of assembling a profile for a fenestration system, the method includes providing first and second members of the profile, and arranging a thermal break within an inner space defined between the first and second members, the thermal break including a body having opposing first and second ends and extending along a centerline, and first and second tabs provided at the first and second ends, respectively, and extending laterally in opposite directions from the body along the centerline, each tab including a head extending from the body, and a stem extending from the head, wherein the head exhibits a larger cross-section than the stem.
  • the method further includes advancing the first and second tabs into first and second channels, respectively, provided by the first and second members, respectively, wherein each channel is defined by upper and lower flanges, temporarily securing the thermal break to the first and second channels by receiving the first and second tabs into the first and second channels, respectively, and crimping the upper and lower flanges of each channel against the first and second tabs, respectively, and thereby permanently securing the thermal break to the first and second members.
  • the present disclosure is related to fenestration systems and, more particularly, to an improved thermal break profile for mating with profile extrusions.
  • the embodiments described herein are directed to the creation of a temporary, rigid pre-assembly of thermal break components in a composite member or "profile" for a fenestration system prior to running the profile through a crimping or rolling operation to thereby make the connection sure.
  • the thermal breaks disclosed include a continuous tab, which helps increase the mechanical interlock between the thermal break and the adjacent profile extrusion. The interlock between the continuous tab and the adjacent profile extrusion allows the preassembled component to remain together while being transferred to a crimping machine and operation. After the crimping operation, the composite profile has greater structural strength because of the continuous tab.
  • the example thermal break interconnections disclosed herein may help increase the structural strength of the composite profile of an assembled fenestration system.
  • FIG. 1 is a cross-section, side view of an example composite member or "profile" 100, according to one or more embodiments.
  • the profile 100 may form part of or otherwise be incorporated into any type of commercial or residential fenestration system including, but not limited to, windows, doors, storefront framing, curtain wall assemblies, window walls, conservatories, balconies, glazed roofing systems, sliding doors, sliding windows, window assemblies, door assemblies, fixed vents, or any combination thereof.
  • the profile 100 may be a designed to be oriented vertically, horizontally, or at any angle therebetween.
  • one or both of the exterior and interior members 102a,b may comprise a monolithic part, but may alternatively be made up of two or more component parts that interlock or otherwise interconnect or engage with one another, as generally depicted in FIG. 1 .
  • the exterior and interior members 102a,b cooperatively define an inner space 104 between the two components.
  • the inner space 104 may be used for accommodating an infill (not shown) of a given thickness to be included in the fenestration system.
  • the infill may comprise, but is not limited to, glass, a foam panel, a structural panel, or a connection to another profile.
  • the inner space 104 generally extends along the entire length of the profile 100.
  • one or more thermal breaks 106 may be arranged within the inner space 104 and secured to the profile 100 to connect the members 102a,b together.
  • two thermal breaks 106 are depicted extending between the exterior and interior members 102a,b, but more or less than two may be employed in the profile 100, without departing from the scope of the disclosure.
  • the two thermal breaks 106 may be substantially the same and otherwise exhibits similar design characteristics, but may alternatively be different.
  • the two thermal breaks 106 may be jointly referred to as a single thermal break that extends between and interconnects the exterior and interior members 102a,b.
  • Each thermal break 106 may comprise a rigid or semi-rigid structure capable of being secured to the profile 100 within the inner space 104. Consequently, the thermal breaks 106 help enhance the mechanical strength of the profile 100. Moreover, however, the thermal breaks 106 serve to improve the thermal performance of the profile 100 by preventing thermal energy loss between the exterior and interior members 102a,b. To that end, the thermal break(s) 106 may be made of a material having a thermal conductivity that is less than the thermal conductivity of the exterior and interior members 102a,b.
  • Example materials for the thermal breaks 106 include, but are not limited to, a polyurethane foam, polyethylene terephthalate (PET), polyamide, nylon, acrylonitrile butadiene styrene (ABS), a polymer, or the like.
  • PET polyethylene terephthalate
  • ABS acrylonitrile butadiene styrene
  • the thermal breaks 106 are configured to be secured between the exterior and interior members 102a,b via a crimped or rolled dovetail engagement. More specifically, each thermal break 106 provides a body 108 having opposing first and second ends 110a and 110b. As illustrated, an axial extension or "tab” 112 may be provided at each end 110a,b of the thermal break 106 and extends laterally from the body 108. The tabs 112 may alternately be referred to as a "leg” or a "fin". In at least one embodiment, the tabs 112 extend continuously along the axial (longitudinal) length of the thermal break 106, but could alternatively extend discontinuously along the axial (longitudinal) length of the thermal break 106.
  • Each tab 112 may be configured to be received within and interconnected with a corresponding channel 114 provided or otherwise defined by the exterior and interior members 102a,b. Accordingly, the tab 112 provided at the first end 110a of the thermal break 106 may be configured to be received within an adjacent channel 114 provided (defined) by the exterior member 102a, while the tab 112 provided at the second end 110b may be configured to be received within an adjacent channel 114 provided (defined) by the interior member 102b.
  • the interconnection between the thermal break 106 and the exterior and interior members 102a,b may be made sure by crimping or rolling (collectively referred to herein as "crimping") portions of the channel 114 into locking engagement with the tab 112, which effectively interconnects the exterior and interior portions across the inner space 104.
  • the design and configuration of the tabs 112 and corresponding channels 114 may provide a temporary interlock or interconnection that allows the pre-assembled components (i.e., the tabs 112 received within the channels 114) to remain together while being physically transferred (moved) to a crimping or rolling tool.
  • the interconnection between the thermal break 106 and the exterior and interior members 102a,b may then be made sure by crimping down on the tabs 112 at each end 110a,b.
  • FIGS. 2A and 2B are enlarged cross-sectional side views of an example thermal break interconnection 200, as indicated in FIG. 1 , according to one or more embodiments.
  • the thermal break interconnection 200 (hereafter “the interconnection 200") includes a tab 112 of a given thermal break 106 received within a corresponding channel 114 of either the exterior or interior member 102a,b of the profile 100 ( FIG. 1 ).
  • FIG. 2A depicts the interconnection 200 in a first or "pre-crimped” or “pre-rolled” state
  • FIG. 2B depicts the interconnection 200 in a second or “crimped” or “rolled” state.
  • the head 202 nonetheless exhibits a larger cross-sectional size as compared to the stem 204.
  • the cross-section of the stem 204 may be constant in the lateral direction away from the head 202, but could alternatively vary in cross-sectional size in the lateral direction, without departing from the scope of the disclosure.
  • the channel 114 is sized to receive and mate with the tab 112, including both the head 202 and the stem 204. More particularly, the channel 114 may include or otherwise be defined by a first or "upper" flange 206a and a second or “lower” flange 206b offset (e.g., laterally, vertically, etc.) from the upper flange 206a.
  • the channel 114 comprises a void defined between the upper and lower flanges 206a,b and exhibits a size and geometry configured to receive the tab 112. More specifically, in the illustrated embodiment, the channel 114 defines a first chamber 208a at its opening sized to receive and mate with the head 202.
  • a second chamber 208b extends from the first chamber 208a and is sized to receive and mate with the stem 204. Accordingly, the size of the first chamber 208a may be larger than the size of the second chamber 208b to accommodate the larger size of the head 202 as compared to the stem 204.
  • the channel 114 transitions between the first and second chambers 208a,b at a lateral protrusion 210 defined on one or both of the flanges 206a,b.
  • the lateral protrusion(s) 210 may provide a hard stop for the tab 112. More specifically, when advancing the tab 112 into the channel 114, the enlarged cross-section of the head 202 may engage the lateral protrusion 210, which stops the tab 112 from advancing further into the channel 114.
  • the second chamber 208b may exhibit a geometry or size that is the same as or slightly smaller than the geometry or size of the stem 204. Consequently, advancing the stem 204 into the channel 114 may form an interference or snug fit with the second chamber 208b such that an amount of retraction force may be required to subsequently remove the stem 204 from the second chamber 208b.
  • the interconnection 200 has been "crimped” or “rolled” and otherwise transitioned to the crimped state by crimping the flanges 206a,b onto the tab 112, and thereby permanently securing the thermal break 106 to the exterior or interior member 102a,b.
  • the crimping operation can be undertaken by conventional or known crimping or rolling machines or devices, which will not be described herein. After the crimping operation, and partly because of the continuous tab 112, the interconnection 200 will exhibit a higher structural strength as compared to conventional thermal break interconnections.
  • first grooves 214a are shown defined on the stem 204, it is contemplated herein to include similar grooves 214a defined on the head 202, or both on the head 202 and the stem 204.
  • second grooves 214b are shown defined on the inner surface of the second chamber 208b, it is contemplated herein to provide the second grooves 214b within the first chamber 208a, or within both the first and second chambers 208a,b, without departing from the scope of the present disclosure.
  • one or more of the grooves 214a,b may axially align such that corresponding pockets (voids) are defined at the interface between the stem 204 and the inner wall of the second chamber 208b, and/or at the interface between the head 202 and the inner wall of the first chamber 208a.
  • the pockets defined by aligned grooves 214a,b may be filled with the adhesive 212 during assembly of the interconnection 200.
  • one or more of the grooves 214a,b may axially misalign such that smaller pockets (voids) are defined at the interface between the stem 204 and the inner wall of the second chamber 208b, and/or at the interface between the head 202 and the inner wall of the first chamber 208a.
  • the grooves 214a,b may prove advantageous in allowing for more surface area contact with the adhesive 212 and for mechanical interlocking with the adhesive 212, which provides increased structural strength to the interconnection 200.
