A gutter insert device is shaped to fit within a gutter hollow channel. The insert is a foamed material and it will at least partially fill the gutter hollow channel to resist accumulation of leaves, sticks and other debris. A top later is formed of reticulated polyurethane foam to resist ultraviolet light and flame retardants. Stock foam raw material is cut so that it will expand to form an elongated insert base.

I claim: 1. An insert device for use with a rain gutter having a hollow channel, the device comprising: an insert base shaped to fit within the rain gutter hollow channel for a substantial length of the gutter and formed of a polyolefin foam; and a top layer positioned above the insert base for substantially the length of the insert base and formed of a reticulated polyurethane foam that is porous so that water will flow through the foam forming the top layer, wherein the insert base includes a surface forming at least a portion of a passage through which water flows along the rain gutter, wherein the insert base supports the top layer and the insert base occupies a greater volume than the top layer formed from porous reticulated polyurethane foam, and wherein both the insert base and the top layer permit water flow in the gutter. 2. The device as claimed in claim 1 wherein the width of the top layer is substantially the width of the insert base. 3. The device as claimed in claim 1 wherein the top layer is treated with a binding agent to extend the life of the top layer. 4. The device as claimed in claim 2 wherein the top layer is treated with a binding agent to extend the life of the top layer. 5. The device as claimed in claim 3 wherein the binding agent is acrylic latex. 6. The device as claimed in claim 3 wherein the binding agent is phenolic latex. 7. The device as claimed in claim 1 wherein the top layer is treated with ultraviolet resistive and flame retardant compositions, and the top layer covers the insert base so that only the top layer is exposed and need be treated with the ultraviolet resistive composition. 8. The device as claimed in claim 1 wherein the polyolefin foam base is formed in an expanded grid, formed by cutting a polyolefin foam material and expanding and separating the cut polyolefin foam material to form the expanded grid, that results in savings in the use of the polyolefin foam material forming the expanded polyolefin foam base and increases water flow and ventilation within the hollow channel. 9. A gutter insert device for use in a rain gutter, wherein the gutter insert device includes a reticulated foamed plastic layer forming a top layer extending from end to end to form an entire upper surface of the gutter insert device, the gutter insert device being supportable in the rain gutter so that the reticulated foamed plastic layer covers the gutter, the reticulated foam top layer allowing rain water to flow through the foam and blocking solid debris, the reticulated foamed plastic top layer including ultraviolet resistive and flame retardant compositions, wherein a portion of the insert device below the reticulated foam layer is at least partially void to form an open flow passage to permit flow of water within and along the rain gutter, wherein a portion of the insert device, comprises an insert base formed of foam other than reticulated foam that supports the top layer and the insert base occupies a greater volume than the top layer formed from reticulated foam, and wherein both the insert base and the top layer permit water flow in the gutter. 10. The gutter insert device of claim 9 wherein the reticulated foamed plastic top layer includes ultraviolet resistive and flame retardant compositions, and the top layer covers the insert base so that only the top layer is exposed and need be treated with the ultraviolet resistive composition. 11. The gutter insert device of claim 10 wherein the foam base layer is formed of a polyolefin foam and the reticulated foamed plastic top layer is formed of a reticulated polyurethane foam. 12. The gutter insert device of claim 9 wherein the foam base layer comprises an extruded foam cut to form an expandable grid in which gaps are formed by cutting the extruded foam.
