Abstract
A lay-in ceiling panel structure, comprising a glass fiber ply, a gypsum board, and a highly perforated vinyl lamina. The ceiling panel structure having noise and sound transmission reduction coefficients in the range of 0.85 to 0.95 sabins and 0.35 to 0.39 dbs respectively. This structure also provides good fire resistance, space efficiency, and a lower surface that is washable and pleasing to the eye. In addition, the glass fiber ply is secured to the gypsum board by droplets of glue which are spaced 1 to 2 inches apart and which are applied 4 to 6 inches away from the outer periphery of the gypsum board. Applying the glue in this way allows the glass fiber ply and vinyl lamina to lay flat even if the board is warped by water leaks, humidity or age.
Claims1
A method for manufacturing a space efficient, fire resistant, lay-in ceiling panel with large noise absorption and sound transmission coefficients, and with a lower surface which is washable and pleasing to the eye, comprising the following steps:
- a. providing a glass fiber ply, a gypsum board, and a textured vinyl lamina which has both a front and a back side;
- b. applying a coating of glue to said back side of said vinyl lamina;
- c. placing the glued surface of said vinyl lamina against the surface of said glass fiber ply;
- d. allowing said glue to dry and form a unitary product;
- e. punching a plurality of holes through said vinyl lamina of said unitary product;
- f. cutting said unitary product to the desired ceiling panel dimensions;
- g. cutting said gypsum board to the desired ceiling panel dimensions;
- h. applying a plurality of glue droplets to one side of said cut gypsum board, wherein said glue droplets are spaced 1 to 2 inches apart and 4 to 6 inches away from the outer periphery of said gypsum board;
- i. placing the glued surface of said gypsum board against the glass fiber surface of said unitary product;
- j. aligning said gypsum board and said unitary product so that the edges are flush;
- and,
- k. allowing said glue droplets to dry and form the completed ceiling panel.
