Using integrally formed stiles on skins of sheet molded plastics (thermosetting) employed to form the exterior surfaces of a synthetic door having sheets of reinforcing materials adhered to the inner surface of each of the skins, the skins can be connected through the integral stiles and slats of a fire proof materials can be affixed to these stiles and rails closing the top and bottom opening between the skins to increase the fire resistance of the resulting door when the core is filled with a phenolic foam. The structure described reduces the weight of the resulting door and places the fire resistant materials around the door edges which are the most susceptible to failure during a fire while structurally tying the slats together through the sheets of carbon fiber or fiberglass disposed on the inner surfaces of the skins whereby failure (disintegration) of the skins during a fire will not lead to a collapse of the door as with some prior art door structures. A slat of polyvinyl chloride can be employed to cover the fire proof slats so the door edges can be trimmed so it will fit into the door frame and the edges will be pleasingly attractive.

A universal removable liner attaches to a Roman shade to block sunlight and provide privacy. The shade retraction mechanism draws the shade up in tiers with one or more lift cords. The liner links to the shade across the top of the shade and at the lift cords, with the tiers formed in the shade lifting the liner in tiers as well. Links between the lift cords and the liner at the shade tier tops are closable loops. A hook-and-loop tape is preattached to the top edge of the liner, while a separate strip of adhesive-backed, mating hook-and-loop tape is furnished for user attachment to the top edge of substantially any tier-lift shade. Once the user joins the shade and liner at the tier tops, the liner forms tiers mirroring the tiers of the shade as the two are raised together.
