The material families of wallcovering, and how the trade classifies them

'Wallcovering' is a trade umbrella that covers everything from a printed paper to a woven reed to a sheet of solid vinyl. The word became standard in the mid-twentieth century precisely because 'wallpaper' no longer described a category that had grown to include materials made of no paper at all. Understanding the families is the difference between guessing and specifying.

Printed paper is the oldest family and the widest in pattern. It is inexpensive, matte, and pleasant in person, but it scuffs, does not tolerate moisture well, and is the least durable of the common types. Non-woven paper is its modern relative — a blend of natural and synthetic fibers engineered to be dimensionally stable, to hang by the paste-the-wall method, and to strip off cleanly in whole sheets, which makes it the most forgiving option for both installer and future occupant.

Vinyl is the workhorse family and comes in gradations. Vinyl-coated paper adds a thin protective film to a paper base for light washability; paper-backed and fabric-backed solid vinyls are progressively heavier and tougher, and fabric-backed vinyl is the standard commercial wall material because it survives scrubbing, abrasion, and daily traffic. The trade sorts these commercial vinyls under CFFA-W-101 by finished weight: Type I runs roughly 7 to 13 ounces per linear yard, Type II about 13 to 22 ounces, and Type III above 22 ounces, with Type II serving as the general-purpose commercial grade for corridors and public rooms.

The natural and specialty families trade durability for texture and depth. Grasscloth, sisal, and other woven naturals; real silk; cork; mica; and metallic leaf read as rich because they are, but most cannot be scrubbed and show seams as a feature rather than a flaw. Specialty finishes — flocks that imitate cut velvet, foils, embossed papers, and printed murals — round out the category, each solving for a particular look rather than a particular stress.

Cutting across the families is a durability language worth knowing. ASTM F793 classifies wallcoverings into six categories, from Category I (decorative only) through Category III (decorative with high serviceability) and on to Categories IV, V, and VI, which map to the Type I, Type II, and Type III commercial grades and are scored on washability, scrubbability, abrasion, and stain resistance. A category number describes what a product can take regardless of what it is made of. Read the family for the look and feel, and read the classification for whether it belongs in the room you have in mind.
