Abstract: A substrate covering system includes a plurality of elongated board members, which are, for example composed of an extruded thermoplastic material. Preferably, each of the elongated board members has a convex inner surface and a concave outer surface, both of which are flattened as the edges of the board member are attached to the substrate. Preferably, the inner surface has notches facilitating adhesive attachment to the substrate, while the outer surface has grooves curved to simulate a wood grain and to prevent slipping. The system may also include an elongated edge trim strip that can be configured to cover several different types of substrate edges.

Abstract: Extruded material for forming blind slats has at least one textured surface with raised areas and adjacent lower areas. After extrusion and texturing processes, the slat material is passed through a spray painting process applying a substantially thicker coating of paint to the raised areas than to the adjacent lower areas.

Abstract: A first version of a multilayer slat for horizontal or vertical blind assemblies includes a translucent inside layer, a first transparent base layer, and a translucent outside layer. This slat may also include a second base layer, which is either transparent or translucent depending on the percentage of light to be transmitted through the slat. The base layer may be of a different color than the inside layer, so that light transmitted through the slat is viewed as being differently colored than light reflected from the surface of the slat. The inside layer of the slat may include a foaming agent producing a matte surface texture. Another version of the multilayer slat includes a laminated inside layer, with a foaming agent in a base layer causing a matte surface texture of the laminated layer.
