Integrated refacing system for suspended ceilings

A method for installing a ceiling refacing system for a subceiling of a type having rectangular panels supported by a suspended framework of longitudinal grids and cooperating transverse grids, each being in the form of an inverted T-bar having horizontal flanges bisected by a vertical web, and peripheral grids each being in the form of an L-bar with a singular horizontal flange, wherein all exposed grid surfaces are covered thereby improving the appearance of said subceiling, said method comprising:

• placing a plurality of mating members configured to cover the T-bar grids and the L-bar grids and the intersections of said grids, said mating members defining T-bar molding means for covering the longitudinal and transverse T-bar grids, cross piece molding means for covering the intersections of one of said longitudinal T-bar grids and two of said transverse T-bar grids, T-piece molding means for covering the intersection of one of said longitudinal T-bar grids with one of said transverse T-bar grids, L-bar molding means for covering the peripheral L-bar grids, and inside corner molding means and outside corner molding means for covering the intersections of the L-bar molding means at the corners of the room;
• the T-bar molding means being linear, the cross piece molding means being X-shaped with four equal arms radiating from a common point at right angles to each other, the T-piece molding means being T-shaped with three equal arms radiating from a common point, two of said arms being linearly configured and the third at right angles thereto;
• the T-bar molding means, cross piece molding means and T-piece molding means each having a flat base with an upper surface defining the interior base and an outer surface defining the exposed face, and opposing exterior edges;
• the T-bar molding means, and the arms of said cross piece molding means and the T-piece molding means having opposing vertical side walls contiguous with said exterior edges, return flanges extending inwardly and disposed along the upper edge of each side wall and having an upward facing surface, a horizontal downward facing surface and an inward facing edge, said upward facing surfaces extending from the vertical sidewalls and forming acute angles therewith and said T-bar molding means and the arms of said cross piece molding means and said T-piece molding means being identical in transverse cross-section enabling intimate cooperation with each other when properly positioned;
• the L-bar molding means being linear, the inside corner molding means and the outside corner molding means being L-shaped with two equal arms radiating from a common point at right angles to each other, and each of said molding means having a flat base with an upper surface defining the interior base and a lower surface defining the exposed face, and opposing exterior edges;
• the L-bar molding means, the inside corner molding means and the outside corner molding means having two opposing vertical sidewalls contiguous with said exterior edges, one of said sidewalls being the taller sidewall and the other sidewall being the shorter sidewall, said shorter sidewall being away from the periphery of the room and having a return flange extending inwardly and disposed along its upper edge, said return flange having a upward facing surface, a horizontal downward facing surface and an inward facing edge, said upward facing surface extending from the vertical sidewall and forming an acute angle therewith and said L-bar molding means and the arms of said inside corner molding means and the arms of said outside corner molding means being identical in transverse cross-section enabling intimate cooperation when properly positioned and the L-bar molding means having notches in the shorter sidewalls spaced and shaped to coact with the ends of the T-bar molding means when properly positioned;
• all of said molding means being made of a flexible and resilient material;
• properly positioning each mating member so that it lies contiguous to the adjacent mating member and in the same plane therewith;
• cutting to proper proportions only those mating members that are needed to fit peripheral areas in the grid system;
• properly positioning the cut mating members as needed such that they cleanly abut contiguous mating members and lie in the same plane therewith;
• removing the rectangular panels;
• applying pliable facing means to the exposed surfaces of the rectangular panels;
• replacing the resurfaced rectangular panel to their former positions;
• whereby said acute angles of the upward facing surfaces of the return flanges assist said mating members in sliding smoothly onto the grids by causing the vertical sidewalls of said mating members to be displaced outwardly by pressure from the flanges of the grids along the angled surfaces as the mating members are pressed upward against said grids, and the mating members are seated onto the grids with minimal upward force so as not to cause distortion or misalignment of said grids and thereafter each mating member lies flat against the grid and contiguous with the adjoining mating member resulting in an unbroken covering over the existing grids and the pliable facing means completely covers the exposed surfaces of the panels providing a new and clean appearance to the entire subceiling.
