Description
- 1. Field of the Invention
- This invention relates to fenestration products composed primarily of plastic.
- 2. Background Art
- Plastic is used in a variety of fenestration products such as skylights and windows in buildings as an alternative to a glass panel. Plastic and glass fenestration panels each have their respective advantages and disadvantages. Glass is relatively inexpensive, has good optical properties, is scratch resistant and stable in a variety of harsh environments. Glass, however, is relatively heavy, susceptible to catastrophic failure and can be difficult to handle and fabricate. There is a wide a variety of plastics available for use in fenestration products. Some are low cost, tough, readily formable and environmentally stable. Many plastics, however, are susceptible to scratching, lose their physical properties with age or exposure to environmental factors, and can be relatively expensive.
- The use of plastic and fenestration products, although a very small portion of the market compared to glass, is still quite significant. Plastic panels are used in doors for example, particularly storm doors to minimize the risk of injury due to glass fracture. Acrylic dome panels are used in both residential and industrial building skylights, as illustrated in U.S. Pat. Nos. 3,434,257; 4,514,944, and 4,344,261. Recently, the plastic dome skylight has been introduced having acrylic dome mounted in a polyurethane frame molded in situ about the dome peripheral edge, as illustrated in published U.S. patent application 2005/0178078, illustrated in website, www.vtechindustries.com/products.html and available from Vtech Industries, Inc. and Carlisle SynTec, Inc.
- The focus of the development efforts in the plastic fenestration product area has been, how to mount the plastic panel to the building opening in a secure leak proof manner, while securely supporting the plastic panel on a frame or curb in a structural manner. Many of the mounting systems are comprised of multiple component parts which require assembly and have joints which are susceptible to water leaks. Some skylights are deck mounted, others use raised curbs. The molded polyurethane frame of the VTech™ skylight is a simple one piece molded structure which is securely bonded to the plastic dome in a leak proof manner resulting in a very high performance skylight. This skylight, however, is expensive to manufacture as the tooling and production equipment needed is costly and the raw material cost of the high performance polyurethane utilized prevents this construction system from being used in low price point skylight applications.
- Accordingly, one of the benefits of the present invention is to develop a low cost fenestration product which is suitable for use in skylights or the like which can match the state of the art water intrusion standards set by the in situ molded polyurethane frame systems. It is a further advantage of the invention to develop a fenestration product which is relatively inexpensive to manufacture and requires minimal investment in capital equipment.
- The fenestration product made in accordance with an embodiment of the present invention includes two main components; a frame and a plastic dome formed of a transparent material which is mounted to the frame. The dome has a central region which transmits visible light and a downwardly extending peripheral edge which extends about the peripheral wall of the frame. The dome is further provided with an outwardly extending flashing flange for mounting the assembly to a wall of a building structure surrounding a building opening.
- In one embodiment of the invention, the frame comprises the unitary plastic ring having a central opening formed therein. The frame peripheral wall is preferably formed of an inverted “U” shape cross-section having an outer peripheral wall cooperating with the plastic dome and an inner peripheral wall aligned with the building opening upon which the fenestration product is mounted.
- The invention further includes the method of manufacturing a fenestration product. The method includes the steps of thermoforming a first plastic sheet into a ring shape frame having a generally “U” shaped cross-section formed by an outer peripheral wall. A second plastic sheet formed of a material capable of transmitting visible light and is thermoformed into a dome having a central portion and a downwardly extending peripheral wall cooperating with the outer peripheral wall of the ring shape frame. The ring shape frame and dome are joined in a nested manner with the dome downwardly extending peripheral flange cooperating with the frame outer peripheral wall, where at least one of the ring shape frame and dome is formed with an integral outward extending flashing flange suitable for mounting the assembly on the building structure.

- Accordingly, a number of representative examples of the present invention are illustrated in the drawings and described herein. In the first example,
skylight assembly 10 is illustrated inFIGS. 1 and 2 . Skylight 10 has two main components as best seen in theFIG. 2 cross-sectional view illustrating the skylight mounted to an opening in abuilding roof 12. The skylight includes adome member 14 and aframe member 16 which are both formed of sheets of plastic which have been thermoformed to a three dimensional shape using a conventional thermoforming process such as vacuforming, twin-sheet thermoforming or pressure assisted sag forming.Dome 14 is preferably formed of a light transparent and plastic material such as acrylic or polycarbonate. Depending on the application, the dome may be transparent or may be translucent. A translucent layer having a whitish color can allow light to pass through and act as a diffuser.Plastic dome 14 has acentral panel 18 forming a dome shape, a downwardly extendingperipheral wall 20 and an outwardly extending flashingflange portion 22.Dome 14 is secured to aperipheral wall portion 24 offrame 16.Frame 16 is also thermoformed of a plastic sheet with the peripheralouter wall 24 forming an annular ring to supportdome 14. Theframe 16 defines a light transmittingcentral region 26 to allow light passing through thedome 14central panel 18 to freely enter thebuilding roof 12. - In the first embodiment of the invention illustrated in
skylight assembly 10, theframe 16 has a peripheral wall portion which in cross-section forms an inverted “U” shape having aninner wall portion 28 andupper wall 30. Extending radially outward from outerperipheral wall 24 is a flashingflange 32 which underlies flashingflange portion 22 ofdome 14. Optionally, innerperipheral wall 28 extends downwardly into the building slightly below the level of the flashingflange 32 as illustrated inFIG. 2 in order to help align the skylight with the opening formed in theroof sheathing 34.Frame 16 may be formed of a different plastic material than thedome 14 since transparency is not required in the illustrated embodiment. The frame plastic material is preferably of a material which can easily be bonded to the frame using conventional adhesives, solvents or weldments. In the embodiment illustrated, the cavity formed within the inverted “U” shaped cross-section offrame 16 is filled with afoam insulation material 36. - In a typical 2′×4′ building opening size application,
skylight 10 can be manufactured using a dome formed of acrylic having a wall thickness prior to thermoforming of 0.60 inches to 0.236 inches or the wall thickness capable of supporting an ultimate load needed in service or required by a regulation or an architect. These ultimate loads may include in excess of 20, 40, or 60 pounds per square feet as tested using procedure A of ASTM E330 after stabilization according to procedure A of ASTM D618. The frame may be formed of acrylic or a different plastic material such as acrylic polycarbonate, terephthalate, polyoxymethylene, polyolefin, and/or polyvinylchloride, since light transmission is not an issue. The wall thickness of the frame need not be thick, particularly when the frame filled with arigid insulation foam 36. A wall thickness of the frame can range from 0.030 to 0.236 inches. Foamed insulation material such as polyurethane, expanded polystyrene, or polyisocyanurate can be used having densities between 1 pound per cubic foot and 40 pounds per cubic foot. - Preferably, the outwardly extending flashing
flange 22 extends outwardly from a downwardly extending domeperipheral wall 28 at least 2″ to 9″ and more preferably, 3″ to 7″, in order to provide an adequate overlap to bond to thewater barrier 38 mounted to thebuilding sheathing 34 to allow adequate overlap with theroofing material 40 to prevent water leakage into the building opening. Flashingflange 22 also serves as a mounting flange for attaching the skylight assembly to thebuilding roof sheathing 34. Preferably, corrosion resistant screws or nails are installed through the flashingflange portion 22 into thebuilding roof sheathing 34. The mounting fasteners are preferably located significantly outboard of the dome downwardly extendingperipheral wall 20 and well inboard of the outer peripheral edge of the mounting flange, but not necessarily aligned in a row, in order to minimize stress concentrations in the mounting flange caused by wind load on theskylight dome 18. Ideally, holes for fasteners do not have to be pre-drilled, that way assuring that any unused fastener holes do not provide an entry leak path for water. Holes forfasteners 42 may be drilled at the job site. In order to minimize screw pull out, the screws are preferably provided with a relatively large low profile head or be provided with an associated washer such as a compression washer. -
FIG. 2 a illustrates a cross-sectional view of an alternative embodiment of the skylight assembly.Skylight 44 is made up of three main components; adome 46, aframe 48 and an insulatinglayer 50.Dome 46 andframe 48 are substantially similar todome 14 andframe 16 described in reference to the embodiment invention ofFIG. 2 , except that theframe 48 terminates before the region in which fasteners are inserted. Insulatinglayer 50 is formed of a light transparent plastic material.Insulated layer 50 has a central region able to transmit visible light and an outer peripheral flange which is mounted to one of thedome 46 orframe 48 in order to define enclosedinterior space 52 interposed between the central regions ofdome 46 and insulatedlayer 50.Interior space 52 is filled with a gas such as air or argon and provides a relatively high thermal transmission resistant barrier between the interior of the building and the building exterior.Insulated layer 50 may be bonded to the uppermost portion 54 offrame 48 with an adhesive material or weldment in order to bond the dome to the frame as illustrated. Preferably, one of the top region offrame 54 or the outerperipheral edge 56 of insulatedlayer 50 is provided with agroove 58 as illustrated for retaining a bead of adhesive or sealing material used to bond theinsulated layer 50 to theframe 48. After theinsulated layer 50 installed on the frame, the dome is attached using adhesives as described previously to form a completed assembly. - Yet another variation of the skylight assembly is illustrated in
FIG. 2b . Skylight 62 is made up of adome 64, a frame 66 and two insulatinglayers layers layer 70 while a second adjacent enclosed space 74 is defined between insulatinglayers layers layers layers skylight assembly 44 inFIG. 2 a and skylight 62 inFIG. 2b , respectively, the insulatinglayers -
FIG. 3 illustrates adomed skylight 76 which is part of a larger,tubular skylight assembly 78.Skylight 76 is made up of adome 80, aframe 82 and an insulatinglayer 84 which defines an enclosedspace 86 between the insulatinglayer 84 anddome 80. The upper portion offrame 82 forms anannular trough 88 which serves to trap condensate forming on the inner surface of insulatingpanel 84.Trough 88 prevents condensate from forming on the skylight interior and dripping into the building interior space.Trough 88 is sufficiently large so that the condensate would be collected during periods of condensate formation and subsequently evaporated when the humidity and/or temperature changes sufficiently to cause the condensate to evaporate. Thetubular skylight assembly 78 includes theskylight assembly 76 as well as alight pipe 90 andlight diffuser panel 92.Light diffuser panel 92 is mounted to the ceiling of a room within the building and thelight pipe 90 extends between the diffuser andskylight assembly 76 to carry light from theskylight dome 80 through the light reflective interior surface oflight pipe 90 into the room via the lighttransparent diffuser 92.Light pipe 90 can be made of a flexible conduit as illustrated or a sheet metal duct structure. -
FIGS. 4-6 illustrate a different type of fenestration product constructed in accordance with the teachings of the present invention, namely, awindow assembly 100.Window assembly 100 is adapted for permanent installation in a building opening such as a window into a building basement, crawlspace, or a fixed window in a garage, a garage door, or an entry system.Window 100 is specifically designed to simulate a glass block window commonly seen in building basements. Other textures may be incorporated as desired, such as a texture simulating camed glass. As illustrated in theFIG. 5 cross-sectional view, thewindow assembly 100 includes adome 102, aframe member 104 structure and aninterior layer 106 all formed of a thermoformed plastic material which transmits visible light.Dome 102 has acentral panel portion 108, an outerperipheral wall 110 and an outwardly extendingflashing flange 112.Frame 104 is also formed of a transparent plastic material having an outerperipheral wall portion 114 and a transparentcentral wall portion 116. Theframe 104 is further provided with an outwardly extendingflashing flange 118overlying flashing flange 112 of thedome 102.Interior layer 106 is provided and bonded to frame 104 thereby defining two enclosed interior spaces betweeninterior layer 106 and thecentral panel 108 ofdome 102. Firstenclosed space 120 is interposed betweeninterior layer 106 and framecentral wall portion 116 and secondenclosed region 122 interposed between transparentcentral wall portion 116 and thecentral panel portion 108 ofdome 102. All three components; dome, frame andinterior layer components - In the window assembly embodiment illustrated in
FIGS. 4-6 , thecentral panel 108 andinterior layer 106 are provided withsimulated grout lines 124 molded into the panels. Preferably, the remainder of the visible portion ofpanels frame 104 may be formed of a translucent plastic material allowing light to pass, but, impeding the person's view through the window. -
Window assembly 100 can be manufactured in standard basement window sizes. Windows can alternatively be designed to be mounted from the exterior or mounted from the interior of the building depending upon the architect's specification. Thewindow assembly 100 can be attached to the wood framed window opening with conventional fasteners such as screws and nails. One ormore bezels 126 may likewise be utilized either on the building exterior, building interior or both in order to further seal the joint between the building opening and the window assembly and to enhance the aesthetic appearance of the window. - The plastic sheets utilized to fabricate the three
panels window assembly 100 may be of a variety of materials as described previously. While the frame material can be relatively thin, the panel facing the exterior of the building should be sufficiently thick to provide adequate security and provide acceptable aesthetic appearance. The plastic sheets may also be formed of composite sheets of plastic to provide desired enhancements. Examples of the composite sheets may include UV and/or heat transfer resistant films sandwiched between acrylic plastic. Another example may include an intrusion-resistant mylar film bonded between two thin sheets of polycarbonate plastic. It should be further appreciated that additional thin layers of thermoformed plastic material may be utilized in fabricatingwindow 116 placed betweendome 102 andinner layer 106 to increase the number of enclosed zones within the window to further improve the thermal resistance of the assembly. - Referring to
FIGS. 7 and 8 , these figures illustrate an alternative embodiment of awindow assembly 130 in accordance with the teachings of the present invention.Window assembly 130 is adapted for permanent installation into a building opening such as window into a basement in a concrete block construction house member. As illustrated in theFIG. 8 , an exploded top cross-sectional view, thewindow assembly 130 includes adome 132 positioned in an opening in the concreteblock wall section 134. The dome has acentral panel 136, aperipheral wall 138 and aperipheral flange 142. Thewindow assembly 130 is shaped like a top hat, and defines acavity 146 into which aninterior layer 148 may be inserted. Theinterior layer 148 includes acentral wall panel 150 and aperipheral flange 152. Theinterior layer 148 may be inserted into thecavity 146 with the distal ends 140 of theflange 152 pointed toward thecenter panel 136 of thedome 132. It is understood that the distal ends 140 of theflange 152 may be directed away from thecentral panel 136 without exceeding the scope of this invention. Theflange 152 may vary in size based on the number of inserts desired. Typically, theflange 152 may range in length from 0.25 to 4.0 inches and preferably 0.5 to 2.0 inches. - As an option, a sealed insulating
unit 156 may be inserted adjacent to theinterior layer 148. The sealedunit 156 may include a firstcentral panel 158, a secondcentral panel 160, aperipheral flange 162. The firstcentral panel 158 is hermetically sealed toflange 162 creating anenclosed air space 166. Alternatively, a gas may be injected tospace 166 to improve the thermal transmission resistance of the sealedunit 156. An example of the gas that may be injected is an insulator like argon. Alternatively, other insulators may be in the sealed unit. The insulator may include a vacuum, an aerogel, or a nanogel. Thecavity 166 should be less than 0.625 inches in thickness and preferably less than 0.5 inches in thickness in order to prevent creation of convection cells within the cavity. The convection cells increase heat transmission. It is desirable that theflange 162 be less than 1.25 inch in length so that when placed adjacent to theinterior layer 148, that they form asecond air space 168 that may improve the thermal transmission resistance of thewindow assembly 130. Optional additional interior layers such as a secondinterior layer 170 may be inserted intocavity 146 to further improve the thermal transmission resistance of thewindow assembly 130. A coating, a deposition or a film may be applied to at least one of the components of thewindow assembly 130 including thedome 132, theinterior layer 148, the sealingunit 156, and the secondinterior layer 170. - A
cap 172 opposes thecentral panel 136 and provides closure to thecavity 146. Thecap 172 has aperipheral flange 174 which is adjacent to theflange 142 of thedome 136. Thecap 172 may also havepositioning ribs 178 to assist in centering the cap in the opening inflange 142. Thewindow assembly 130 including thedome 132 and thecap 172 are fastened to theconcrete wall structure 134 using fasteners known in the art. An example of the fastener is amolly anchor 180. For aesthetic purposes, an interiortrim bezel 182 may be attached to thecap flange 174 using a doublestick transfer tape 184. It is understood that other means of attaching the interiortrim bezel 182 that are known in the art may be used without exceeding the scope of the invention. Likewise, an exteriortrim bezel 186 may be attached to the exterior of theconcrete block structure 134 using abarbed insert 188. An example of thebarbed insert 188 is commonly referred to as a “Christmas Tree”. It is understood that thebarbed insert 188 may have individual prongs or be part of a more continuous ridge of barbed inserts. Thewindow assembly 130 may optionally be insulated by injecting a foamedsealer 190, such as a foaming polymer like foamed polyurethane into a gap between thedome 132 and concreteblock wall section 134 before application of thebezel 186. - The invention further includes a method of forming a fenestration product assembly. The method includes steps of thermoforming a first sheet of plastic into a ring shape frame having a cross-section and the general shape of an inverted “U”. A plastic dome is thermoformed from a second sheet of plastic material which transmits visible light defining a dome having a central region and a downwardly extended peripheral flange and a flashing flange extending outwardly from the outer peripheral wall. In one preferred embodiment of the method the central portion of the ring shape frame is cut out forming a central opening through which light can pass. The ring shaped frame and dome are then joined in a nested manner with the dome downwardly extending peripheral wall cooperating with the outer frame peripheral wall. Alternatively, the flashing flange may be omitted from the dome and provided on the ring shaped frame or flashing flanges may be included on both the dome and the ring shape frame.
- The method of forming the fenestration product further includes the step of forming a transparent or translucent insulating layer which is interposed between the frame and the dome and bonded to at least one of the frame and the dome to define an enclosed space between the insulating layer and the dome to increase the thermal resistance value of the assembly. Alternatively, the method may include forming a second insulating layer interposed between the first insulating layer and the dome in order to define two separate enclosed regions between the dome and the two insulating layers to further increase the thermal resistance value of the assembly. It is understood that enclosed regions may include ventilating holes to allow relatively small transfers of gas to relieve pressure differentials or other issues associated with a sealed chamber exposed to temperature extremes.
- The method may further include the step of filling the “U” shaped channel formed in the frame with the insulating material, such as a polymer foam which is preferably cured in place to substantially fill the “U” shaped trough defined by the frame.
- While embodiments of the invention have been illustrated and described, it is not intended that these embodiments illustrate and describe all possible forms of the invention. Rather, the words used in the specification are words of description rather than limitation, and it is understood that various changes may be made without departing from the spirit and scope of the invention.
