Insulated Tile Flooring

Abstract

Insulated tile flooring may comprise an outer surface used to support temperature sensitive goods and machinery typically used to move such goods into a shipping container or other means of transport. The outer surface may comprise a shell and be composed of injection molded high density polyethylene (HDPE). A shell may define a plurality of void areas conducive to being filled via injection in a top to bottom manner to form an inner fill that may comprise CFC-free foamed-in-place or formed elsewhere, polyisocyanurate foam. A bottom most layer of a tile piece may comprise heavy gauge, reflective, double-sided, reinforced pure aluminum foil. Tiles may be manufactured via tile shells temporally attached and defining an inner void used for forming center insulation. The tile shells may then be separated with the inner foam cut to comport to each shell and foil placed over the exposed insulation.

What is claimed is: 
     
         1 . An insulated floor tile comprising:
 a) an outer shell having an back solid surface and the solid surface having vertical interior fill walls defining honeycomb voids;   b) insultation disposed withing the honeycomb voids;   c) foil attached to an inferior side of the insulation.   
     
     
         2 . The insulated floor tile of  claim 1  wherein the outer shell defines a plurality of fill voids to comport with injection of insulation into the plurality of honeycomb voids. 
     
     
         3 . The insulated floor tile of  claim 2  wherein the back solid surface of the outer shell is further defined by surface creases. 
     
     
         4 . The insulated floor tile of  claim 3  wherein the surface creases define a plurality of honeycomb shapes upon the back sold surface of the outer shell. 
     
     
         5 . The insulated floor tile of  claim 1  wherein the outer shell is comprised of high density polyethylene. 
     
     
         6 . The insulated floor tile of  claim 1  wherein the insulation comprises polyisocyanurate foam. 
     
     
         7 . The insulated floor tile of  claim 1  wherein the foil comprises reflective, double-sided reinforced aluminum foil. 
     
     
         8 . A method of manufacturing insulated floor tile, the method comprising the steps of:
 a) attaching a first outer shell to a second outer shell, with the first and second outer shells each comprising a back side, an inner open side, with the inner open side comprising a plurality of interior honeycomb walls with the honeycomb defining a plurality of honeycomb fill voids;   b) using insulation material to fill the honeycomb fill voids;   c) cutting the insulation at a junction where the first and second outer shells are in contact;   d) placing foil over the exposed insulation contained in each outer shell.   
     
     
         9 . The method of  claim 8  further comprising the step of using of high density polyethylene in the construction of each outer shell. 
     
     
         10 . The method of  claim 8  further comprising the step of using polyisocyanurate foam as the insulation material.
