BACKGROUND

In sub-freezing climates, snow and ice accumulation on surfaces can affect all types of structures that are exposed to the environment. In particular, roadways, driveways, sidewalks, and roofs and gutters of buildings may be susceptible to ice build-up and related damage. Additionally, there are considerations associated with working at certain worksites such as oil platforms and ships with exposed decks and passageways in freezing temperatures. Snow-melting and de-icing systems exist for applying heat to the snow and ice, or to the snow-/ice-covered surfaces, referred to herein as “heated surfaces.” The thermal energy melts the snow and ice and reduces the associated hazards.

Heated surfaces can generally include a conductive walking surface with a thermal generation system fastened to the underside of the walking surface. The conductive walking surface can be supported by a support system, generally made of metal. The support may rest on a substrate including, but not limited to, walkways, stairs, or decks of oil platforms or ships. The conductive walking surface can utilize metals such as aluminum or steel to transfer heat from the thermal generation system to the walking surface. Heat loss from a conductive walking surface can decrease the energy efficiency and effectiveness of the thermal generation system.

SUMMARY

Accordingly, an improved heated surface that is energy efficient is desired.

In accordance with some embodiments of the invention, a deicing cassette for connection to a substrate is provided. The deicing cassette includes a panel having a top, an underside, and a plurality of edges, the top of the panel configured as a walking surface. The deicing cassette further includes a heating system secured in thermal contact with the underside of the panel. Additionally, the deicing cassette includes 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.

In accordance with some embodiments of the invention, a heating cassette for connection to a substrate is provided. The heating cassette includes a conductive panel having a top, an underside, and a plurality of edges, the top of the panel configured as a walking surface. The heating cassette further includes a heating system, having a heat tracing cable secured in thermal contact with the underside of the panel. The heating cassette further includes a polymeric support system, including 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 is configured to insulate the underside of the panel from the substrate.

These and other objects, features, and advantages of the invention will become apparent upon reading the following detailed description of exemplary embodiments of the invention, when taken in conjunction with the appended claims.
