Abstract
An insulated cover for the top of an outdoor patio heater includes a toolless fastening system and multiple layers of material. The upper layer is silicone-coated fiberclass cloth; the lower layer is a high-temperature fiber glass fabric, and those enclose an insulating layer of needle mat. The upper and lower layers are formed into substantially conical shapes using three radial sewing darts that are offset from the center of the layer. The fastening system has three sprung hooks spaced around the underside of the cover to hold the cover on the conical metal top of the heater. The hooks are fixed by lacing anchors to the lower and insulating layers.
