Structurally strong, non vapor, non moisture absorbing, spa/hot tub cover
First Claim
1. A structurally strong, non vapor, non moisture absorbing, spa/hot tub cover, comprising the assembled combination of laminations of materials, adhesives, sealants, and both aluminum and plastic angle reinforcements arranged as follows:
- (a) an overall shape defining volume of expanded polystyrene cut or formed as a cover to match the respective top planar opening of a particular spa/hot tub;
(b) a complete surrounding layer of contact cement adhered to all the surfaces of the expanded polystyrene and dried to become an impervious vapor, moisture, and water, barrier to keep the expanded polystyrene dry;
(c) selected lengths of aluminum angle placed at selected places about the periphery of the expanded polystyrene and adhered thereto to serve as places to receive fasteners, later selected to hold in place selected items such as handles and hinges;
(d) a continuous polypropylene scrim foil adhered to and extending throughout the entire bottom, entire sides, and entire peripheral top edges of the expanded polystyrene, being secured by contact cement;
(f) a continuous closed cell foam of polyethylene extending entirely underneath the continuous polypropylene scrim foil and adhered thereto in selected places;
;
(g) a continuous thermally stable and gas impermeable polyvinylchloride polyester laminate extending entirely underneath the continuous closed cell foam, and entirely up and alongside the side edges of the continuous closed cell foam and the side edges of the continuous polypropylene scrim foil, and adhered thereto;
(h) a continuous weatherable plastic extending entirely over the contact cement coated overall shape defining volume of expanded polystyrene, the top edge of aluminum angles, the folded over edge of the continuous polypropylene scrim foil, and adhered to all of them;
(i) A cyanoacrylate instant adhesive spread near all the edges of the continuous weatherable plastic;
(j) a plastic angle positioned about all the top and side edges of the continuous weatherable plastic and adhered thereto via the cyanoacrylate instant adhesive, and about the top and side portions of the upturned portions of the continuous thermally stable and gas impermeable polyvinylchloride polyester laminate and adhered thereto via the cyanoacrylate instant adhesive; and
(k) a continuous sealing bead of a weatherable plastic in an applying solution of methylene chloride located where the plastic angle stops above the continuous weatherable plastic and where the plastic angle stops by the polyester reinforced laminate, to create a vapor, moisture, and water seal.

Abstract
A spa/hot tub cover is structurally strong to essentially completely cover an opening of a spa/hot tub except for a limited vent, and withstand a person'"'"'s weight. In so doing the spa/hot tub cover itself will not absorb vapor, moisture, or water, and thereby not become heavier because of the containment of moisture. The interior of the spa/hot tub cover has several barriers to any possible absorption of vapor, moisture, or water, whereby, if an outside or outer barrier is punctured, only a small quantity of vapor, moisture, or water, will be absorbed. At a central portion of this cover, commencing from the top and continuing on down through to the bottom, the following layers of an overall lamination are: a top weatherable plastic; a contact cement serving as a sealant and adhesive; an expanded polystyrene shaped to define the shape of the spa/hot tub cover; a contact cement serving as a sealant and adhesive; a polypropylene scrim foil; a contact cement; a closed cell foam of polyethylene; and then a bottom polyester fabric reinforced polyvinylchloride. The laminations of this central portion continue on to the periphery of each spa/hot tub cover. Where subsequent fasteners may be received, aluminum angles are selectively positioned about this periphery. The polypropylene scrim foil continues up and over the periphery of these laminations. The bottom polyester fabric reinforced polyvinylchloride also continues up alongside the periphery of these laminations. A vinyl angle is adhered about the top corner of the periphery of these laminations having a leg horizontally overlapping the periphery edge of the weatherable plastic and having a leg vertically overlapping the upturned portions of the polyester fabric reinforced polyvinylchloride. A sealing bead is located where the horizontal overlapping leg of the angle is positioned on the top weatherable plastic and where the vertical overlapping leg of the angle is positioned on the polyester fabric reinforced polyvinylchloride, thereby completing the assembly of this structurally strong, non vapor, non moisture absorbing, spa/hot tub cover. This cover in various embodiments has a sloping water draining top surface, has multiple sections, has hinges, has handles, and/or has gas spring actuators used during removal and replacement.
