PVC wallpaper has a fabric substrate coated with liquid vinyl or acrylic. The decorative layer is printed on this coating. This is generally considered more "breathable" wallpaper which makes it best for use in low moisture rooms, like living areas.
Vinyl Coated Wallpaper
Vinyl Coated wallpaper has a paper substrate on which the decorative surface has been sprayed or coated with an acrylic type vinyl or polyvinyl chloride (PVC). These wallpapers are classified as scrubbable and strippable, and are suitable in most any area. These papers are better resistant to grease and moisture than plain paper, and are good for bathrooms and kitchens.
Vinyl / Solid Sheet Vinyl
Paper Backed Vinyl/Solid Sheet Vinyl- this wallpaper has a paper (pulp) substrate laminated to a solid decorative surface. This type of wallpaper is very durable since the decorative surface is a solid sheet of vinyl. It is classified as scrubbable and peelable. Solid sheet vinyl can be used in most areas of the home since it resists moisture and is stain and grease resistant. However, this type of wallpaper will not withstand hard physical abuse (like mudrooms or storage areas).
