CLAIMS

What is claimed is:

1. A deicing cassette for connection to a substrate, the deicing cassette comprising:

a panel having a top, an underside, and a plurality of edges, the top of the panel configured as a walking surface;

a heating system secured in thermal contact with the underside of the panel; and a polymeric support system fastened to at least one edge of the panel and configured to support the panel and provide the panel at least one of thermal insulation or galvanic insulation from the substrate.

2. The deicing cassette of claim 1, wherein the polymeric support system further comprises at least one polymeric support disposed on a central portion of the underside of the panel.

3. The deicing cassette of claim 1, wherein the polymeric support system comprises fiber reinforced polyester.

4. The deicing cassette of claim 3, wherein the polymeric support system comprises pultruded fiber reinforced polyester.

5. The deicing cassette of claim 1, wherein the panel comprises a conductive material, the heating system configured to supply heat to the underside of the panel to conductively heat the walking surface.

6. The deicing cassette of claim 1, wherein the polymeric support system provides convective energy insulation for the deicing cassette.

7. The deicing cassette of claim 1, wherein the polymeric support system comprises a side support fastened to the at least one edge of the panel via one or more fasteners.

8. The deicing cassete of claim 7, wherein the side support forms a wire routing gap proximal to the substrate.

9. The deicing cassete of claim 7, wherein the side support and the panel are arranged to form a cavity with the substrate, the cavity including an insulating layer of air.

10. The deicing cassete of claim 7, wherein the side support comprises:

an outer support wall configured to provide a thermal barrier between the substrate and the panel;

an inner support wall configured to provide a thermal barrier between the substrate and the panel; and

a cable routing area disposed between the outer support wall and the inner support wall.

11. The deicing cassete of claim 10, wherein a power conduit corresponding to the heating system is disposed within the cable routing area.

12. The deicing cassette of claim 1, wherein the polymeric support system comprises at least one panel flap proximal to the at least one edge of the panel.

13. The deicing cassete of claim 12, wherein a portion of the at least one panel flap extends from the top of the panel.

14. The deicing cassete of claim 12, wherein the panel flap is arranged on the panel to contact the substrate to preserve thermal insulation.

15. A heating cassette for connection to a substrate, the heating cassette comprising:

a conductive panel having a top, an underside, and a plurality of edges, the top of the panel configured as a walking surface;

a heating system comprising a heat tracing cable secured in thermal contact with the underside of the panel; and

a polymeric support system comprising:

at least one side support fastened to a first edge of the panel;

at least one panel flap fastened to a second edge of the panel; and at least one center support disposed on a central portion of the underside of the panel,

the polymeric support system configured to insulate the underside of the panel from the substrate.

16. The heating cassette of claim 15, wherein the polymeric support system comprises pultruded fiber reinforced polyester.

17. The heated cassette of claim 15, wherein the at least one side support comprises:

an outer support wall configured to provide a thermal barrier between the substrate and the panel;

an inner support wall configured to provide a thermal barrier between the substrate and the panel; and

a cable routing area disposed between the outer support wall and the inner support wall.

18. The heated cassette of claim 17, wherein a power conduit corresponding to the heat tracing cable is disposed within the cable routing area.

19. The heated cassette of claim 15, wherein the at least one side support comprises an engagement channel configured to receive a cassette fastener.

20. The heated cassette of claim 15, wherein the at least one side support, the at least one panel flap, and the panel are arranged to form a cavity with the substrate, the cavity including an insulating layer of air.
