At Carpet Tile USA, we pride ourselves on providing high quality carpet tile at an affordable price. Many carpet tile retailers sell second or third quality carpet tile, which means that the carpet tile contains manufacturing defects. These defects could range from separating of the backing, or missing fibers. Carpet Tile USA only sells first quality carpet tile, which means that our carpet tile is free of manufacturing defects. The Shaw River Rock carpet tile is 24" X 24". Each case contains 12 tiles, and covers 5.33 square yards (48 square feet). This tile has a PVC backing. Carpet tiles provide the perfect flooring option for any area of your home, business, or office. It is recommended to use flooring adhesive to place these carpet tiles down. Double-sided carpet tape works as well. These tiles are NOT peel and stick tiles.
