Description
The present invention relates in general to an improved skylight construction, and is concerned, more particularly, with an improved curb frame construction particuLarly as it pertains to improved thermal characteristics of the skylight and ease of fabrication. The skyligh-t described herein is particularly characterizecl by an improved resis-tance to thermal transfer of heat through the skylight.
One typical prior art skylight fra~e i5 made of a metal material such as an extruded aluminum.
S~e, for example, U. ~. Patent 4,073,097, issued February 1~, 1978. One of the problems with such curb frames is that they pe~mit heat conduction there-through. Furthermore, there is a tendency in cold weather for condensation to form because of an insufficient temperature differential between the inside and outside of the panels or domesn Accordingly, curb frames have also been constructed of a the.rmo-plastic material such as polyvinylchloride~ In either case, the thermal transfer is to be minimize~.
Accordingly, i.t is an object of the present i.nventio.n to provide a skylight construction that is particularly characterized by improved thermal trans-~er so as to provide increased resistance to thermal transfer of heat through the skylight~
~ -3-. ~
Another object of the ~resent invention is to provide an improved skylight construction that is easier to fabricate ~pro~iding an interconnecting arrangement for a section of the skylight that does not require welding. More par~icularly~
recesses are provided in the bottom of ~he curb for permitt-~ing a snap engagement o the inner and ou~er aluminum walls forming the support for under the curb.
? ~ Still another object of the present invention is to provid , an improYed skylight curb frame construction combining a curh of a rigid ~hermoplastic in combination l~ith a flexible thermoplastic forming a plurality of gaskets for sealing the - ; curb frame to, not only the dome but also the support member for the curb frame.
Another object of the present invention is ~o provide a skylight construction that minimizes air exfiltra~ion ; ~ through the skylight. The forming of a positive seal is im-, portant with regard to the skylight. The preferred composite $ ~ PVC is important rom the standpoint of energy conservation.
.
_m~ of the Invention ~ To accomplish the foregoing and other objec~s of ~he ! I invention, there is provided a skylight cons~ruction adapted i to be itted into an opening in a building such as the roof ' of a residential house. This skylight construction comprises ~q 1 25 a curb frame extending abou~ the opening and having means for i receiving nails or the like for securing the frame in place about the opening. In one embodiment, one or more transparent or translucent thermoplastic domes cover the opening and ex-tend at the edge to the curb frame. In another embodiment the dome may be replaced by one or more one or more Elat glass panels. A retainer extends about the periphery of the ~r`skylight for holding the dome or panel on the curb frame. In accordance with the preferred form oE this in~en~ion the curb frame is constructed o a rigid plastic, preferably polyvinyl-chloride (P~C). The curb rame may be heat welded at the!
~' s a~
corners of the frame and has integral therewith a plurality ~-p of gaskets formed of a flexible portion of P~C or the like s fo~ sealing between the curb frame and the covering means ovèr the opening. Also, gasket means are provided in~egral 5 with the curb frame for sealing wi~h the aluminum support wa~ particularly the outer aluminum wall. This eliminates energy waste by air infil~ration and prevcn-ts water leakage.
The curb frame may be constructed of a rigid PVC having a hardness in the shore scale for (D), while the gasket may 10 be of a flexible PVC having a hardness in the shore hardness . range 'IA". A heat plattent high frequency, ul~rasonic or ~' other thermoplastic welding technique may be used to weld the curb, and also a~ the same time weld the gasket for a continuous seal. This provides an extremely tight skylight 15 construction which is an energy-saving feature o~ the inven-tion. The curb frame preferably also includes a third gaske-t that is flexible, integral with the curb frame and contacts the retaining means for the pla~es or domes to form a seal therewith~ The curb frame may have a hollow construction3 20 preferably has weep holes therein, and includes means on the inner side thereof defining a condensation gutter. rhe curb frame is also preferably provided with two bottom re-cesses into which the inner and out r aluminum walls snap fit without the requirement for any welding between ~ ese 25 walls. These aluminum walls or skins define a compartment for containing fiber glass insulation and form the underside support for the curb frame.
