Abstract:
A method for encasing a ceiling tile comprising the steps of:positioning a back surface of a ceiling tile adjacent to a vacuum table; framing the ceiling tile; placing an air-permeable facing over a front surface of the ceiling tile with the facing extending beyond the perimeter of the ceiling tile and being supported by the framing; covering the facing with an air-impermeable cover; drawing the facing onto the ceiling tile with a vacuum applied through the vacuum table; positioning the front surface of the ceiling tile adjacent to the vacuum table; placing an air-impermeable backing over the ceiling tile, said backing extending beyond the perimeter of the ceiling tile; drawing the backing onto the ceiling tile with the vacuum applied through the vacuum table, whereby the ceiling tile is encased between the facing and backing, and the backing and facing further form a flap that seals about the perimeter of the ceiling tile.
