Abstract: An architectural tile is made of a panel capable of overlapping a laterally adjacent panel as well as a longitudinally adjacent panel. The panels include a first part for being secured to a wall or roof and which includes a locking ridge for engaging a second part of an overlapping panel. The locking ridge terminates below the upper edge of the panel to allow a longitudinal overlap of the panels.

Abstract: An architectural tile is formed of a body portion having securing means extending therefrom. A plurality of tiles are secured together to form a roof or wall covering. The securing means include leg portions which are flexible and guide bars for directing securing means from facing tiles into interlocking positions. The legs are of sufficient length to provide flexibility and to prevent leakage of water into the gaps between adjacent lower tiles. Ridges extend from the lower surfaces of the body portions for spacing an overlapping tile from an overlapped tile to form a shadow line. The body portions may be flat or curved or a combination of flat and curved portions.

Abstract: A two piece extrusion for use in forming storm windows or the like is cut to frame an existing window opening. One extrusion comprises a locking element of which the main portion is formed of a substantially rigid plastic material, which is provided with spaced integral, flexible projections extending angularly outwardly from the stem of the element. The locking element is adapted to be inserted in a channel which comprises the second extrusion. The second extrusion is formed into a rectangular frame so as to hold a flexible translucent, transparent, or opaque sheet locked in the channel by the first extrusion. In assembly the flexible sheet is forced into the channel by the insertion of the locking element. In so doing the flexible sheet is stretched to give a smooth appearance. A second channel is formed by the second extrusion which also extends completely around the frame but is located inwardly of the first channel.

Abstract: A one piece extrusion for use in the manufacturing of structures including structures such as frames, wall partitions, display boards, signs, covers, filters, screens, mesh, window sash and window-like structures, such window frames, window sash and other structures and methods of making such structures and especially of making window sash. The extrusion comprises a locking element of which the main portion is formed of a substantially rigid plastic material, which is provided with spaced integral, flexible projections extending angularly outwardly from the stem of the element, and which is adapted to be inserted in a channel formed in the entire periphery of a rectangular frame so as to hold a flexible translucent, transparent, or opaque sheet locked in the channel. The flexible sheet is forced into the channel. In so doing the flexible sheet is stretched to give a smooth appearance and is locked in the channel and sealed by the extrusion.
