ABSTRACT:
A smooth, flat plastic film sheet forms a ceiling covering. The dimensions of the room are measured. The dimensions are proportionately reduced. A plastic sheet film is prepared to the reduced dimensions. A plastic edge connector is ultrasonically welded to the entire periphery. A connector strip is fastened to the upper wall entirely around the room. Hot air is blown to the top of the room. The edge connector at the edge of the film is snapped into the connector strip, starting at the corners. The film and edge connector are of a plastic that stretches when hot. The edge connector, when completely fitted into the connector strip pulls the film taut as the film shrinks when cooled to room temperature to provide a perfectly fitted, wrinkle free covering. The same invention may be used to cover a wall. The special edge connector is provided with a snap latching feature to provide audible indication of correct locking in place and the edge connector has a provision for easy unlatching for removing the covering.
