Spa cover

Abstract

A cover for a spa is disclosed which is made of a foam core with a geotextile layer and a polyurea layer. The cover is sufficiently strong to prevent individuals or animals from falling into the spa yet light enough to allow for easy removal. The cover also provides a great amount of insulation for the water in the spa order to maximize the efficiency of the spa's heating system.

1 . A spa cover comprising: 
 a body comprising, 
 a rigid foam center;  
 a woven layer of polymer material substantially encasing the center; and  
 a polymer layer substantially encasing the woven layer.  
   
   
   
       2 . The spa cover of  claim 1 , wherein the center comprises a polymer selected from a group consisting of polyethylene, polystyrene, polypropylene, or polyurethane.  
   
   
       3 . The spa cover of  claim 1 , wherein the woven layer comprises TERETEX HBG 16™.  
   
   
       4 . The spa cover of  claim 1 , wherein the polymer layer is selected from a group consisting of an aliphatic polyurea, an aromatic polyurea, hypolon, polyvinyl chloride, polyethylene, or polyurethane.  
   
   
       5 . The spa cover of  claim 1 , wherein the cover comprises a plurality of bodies.  
   
   
       6 . The spa cover of  claim 5 , wherein the bodies are releasably coupled.  
   
   
       7 . The spa cover of  claim 1 , wherein the body further comprises a flexible flange at an external perimeter of the body.  
   
   
       8 . The spa cover of  claim 1 , wherein the flange is configured to releasably couple to a spa.  
   
   
       9 . A spa cover comprising: 
 a body comprising, 
 a rigid foam center;  
 a layer substantially encasing the center; and  
 a polyurea layer substantially encasing the layer.  
   
   
   
       10 . The spa cover of  claim 9 , wherein the center comprises a polymer selected from a group consisting of polyethylene, polystyrene, polypropylene, or polyurethane.  
   
   
       11 . The spa cover of  claim 9 , wherein the layer comprises a woven layer.  
   
   
       12 . The spa cover of  claim 11 , wherein the woven layer comprises TERETEX HBG 16™.  
   
   
       13 . The spa cover of  claim 9 , wherein the polyurea is an aliphatic polyurea.  
   
   
       14 . The spa cover of  claim 9 , wherein the polyurea is an aromatic polyurea.  
   
   
       15 . The spa cover of  claim 9 , further comprising a plurality of bodies.  
   
   
       16 . The spa cover of  claim 15 , wherein the bodies further comprise a means for releasably coupling the bodies.  
   
   
       17 . A spa cover comprising: 
 a body having an edge comprising, 
 a rigid foam center having a top, a bottom and a plurality of sides;  
 a first woven layer of polymer material substantially covering the top and plurality of sides;  
 a flexible flange formed along the edge of the body adapted for coupling the body to a spa; and  
 a polymer layer substantially encasing the first woven layer and the bottom of the foam center.  
   
   
   
       18 . The spa cover of  claim 17 , wherein the first woven layer comprises a plurality of woven layers.  
   
   
       19 . The spa cover of  claim 17 , wherein the first woven layer covers the bottom of the center.  
   
   
       20 . The spa cover of  claim 17 , wherein the flange is formed of a second woven layer.
