Abstract: A protective wall paneling kit for recesses, for example, that surround a bath tub or shower stall, is disclosed. The kit, and its several components are primarily of extruded plastic. Extruded sheet panels are provided having a relatively thick structural base member, such as acrylonitrile-butadiene-styrene tripolymer, co-extruded with a thin layer of a protective plastic such as an acrylic having enhanced impact properties. Adjacent panels are joined and outward facing edges are sealed by further extruded joining and sealing strips, of a plastic such as polyvinyl chloride. The strips are of a single profile shape and are adaptable for either use. The panels and strips may be provided with sizing grooves during extrusion to allow convenient size adjustment. The joining and sealing strips may also be of a dual durometer polyvinyl chloride to permit hinging or tear stripe adjustment. The adjustment features allow the kit to be provided in a wide range of standard embodiments made from limited modular sizes.

Abstract: A multiple track window, preferably with extruded plastic framing and glazing sealing strips, is described. Glazing panels are releaseably held and slideable for opening within side framing channels which are formed by releaseably interlocking members which may be integrally hinged to one another. The glazing panels are also directly removeable from the channels formed. Sealing strips with tubular protrusions are attached to adjacent edges of the glazing panels and provide a seal at their central meeting. Such a sealing strip is also adapted for use as a sill sealing strip. Thus, a tightly sealable and efficient insulating window formed from improved elements in accordance with the disclosure is provided. The glazing panels of the window may be opened to adapt to climactic conditions or ventilation requirements, or may be removed for cleaning, maintenance or other reason.

Abstract: Improved panel holding and jointing strips and insulating window assemblies made therewith are disclosed. Hinged perimeter and jointer strips allow the use of insulating panels in large windows with multiple panes and commercial applications where strength and esthetic appeal are important considerations. The strips are also adapted to receive glazing or insulating panels of various thicknesses and are also useful in providing insulating windows for existing prime windows in an array.
