Abstract
Methods, systems and devices for making a pedestrian, vehicular, or other surface resistant to frost, snow and ice by use of heat are disclosed. A composite base or deck element includes a recess to accommodate heating element. A thermal insulator has an upward facing layer of heat-conductive aluminum foil, above which sits the heating element. On top is a pedestrian, vehicular, or other exposed surface, for example a tactile warning surface.
Claims9
A frost resistant tile system consisting of:
- a layer of thermal insulation;
- a first deck element, the first deck element having an upper surface and lower surface defining a thickness therebetween, the lower surface of the first deck element disposed above the layer of thermal insulation, the first deck element including a groove sized and shaped to receive a heating element;
- a heating element seated in the groove, the heating element having an upper surface and lower surface defining a thickness therebetween with the lower surface of the first deck element disposed below the lower surface of the heating element;
- at least one clip disposed within the groove of the first deck element with the heating element releasably secured in the at least one clip,
- the at least one clip having an interior surface and an outer surface, the interior surface having a contour complimentary to the geometry of the heating element, the outer surface having a contour complimentary to the geometry of the groove of the first deck element;
- a layer of metallic thermally conductive material above at least a portion of the upper surface of the first deck element and disposed directly above the heating element;
- a surface tile above the layer of thermally conductive material;
- and
- a controller electrically connected to the heating element so as to be able to activate and deactivate the heating element.
