Vinyl sheet is a large roll of vinyl flooring that can either be felt-backed, vinyl-backed or modified loose-lay. Each is designed for different methods of installation.
Felt-backed: The most common type of vinyl sheet, with a layer of felt added to the back for strength and cushion, and installed with an adhesive.
Vinyl-backed: The least common format for vinyl sheet; installed by gluing to the floor only at the edges, and generally recommended for professional installation only.
Modified loose-lay: Contains a fibreglass backing for greater strength and stability than felt or vinyl-backed, and is installed without adhesives. Double-sided tape secures the sheet near appliances and doors.
