ABSTRACT:
A carpet tile of improved dimensional stability having a hot melt composition backing layer and which has a secondary backing of a glass fiber tissue sheet material directly adjacent to a non-woven fibrous sheet material, such as a polypropylene sheet material. The backing layer penetrates the glass fiber tissue sheet material and partially penetrates and bonds the fibrous sheet material which forms the exterior surface of the secondary backing. The method of producing the carpet tile includes forcing the liquid, hot melt composition into the secondary backing sheet employing a roll-over-roll applicator.
