Sheet vinyl flooring is vinyl flooring that comes in large, continuous, flexible sheets. A vinyl sheet floor is completely impermeable to water, unlike vinyl floor tile, which comes in stiff tiles, and vinyl planks, which come in interlocking strips. It is sometimes called linoleum after a visually similar product of different (linseed oil) chemical composition. [1]
Vinyl flooring is extensively used because it is water-impervious, fairly durable, adjustably resilient and insulating, easy to install, available with a variety of appearances, and inexpensive. [2] Custom-print vinyl sheet flooring may cost an order of magnitude more, if ordered commercially,
However, vinyl flooring has environmental concerns in manufacturing, use, and disposal. [3] [4]
The three basic categories of vinyl sheet flooring are homogeneous, inlaid, and layered composite. Vinyl flooring differs in manufacturing process and polyvinyl chloride content. [5]
Composite manufacturing begins with a fibrous backing sheet. This was often felt or paper (before 1980, often with asbestos [6] ); more modernly, it is generally fiberglass. This sheet is coated in vinyl and plasticizer. The resulting sheet is printed and possibly embossed (the print layer). Then the sheet is coated again with one or more protective wear layers, the topmost of which may be polyurethane, to avoid waxing. [7]
Cushioned vinyl sheet was developed in the 1960s. It features closed-cell-foam lower layers. A cushioned floor has more give and spring.
Low-VOC vinyl flooring is certified by the industry group Resilient Floor Covering Institute. However, it still emits volatile organic compounds such as phenol; ventilation may not appreciably lower concentrations.
Manufacture of polyvinyl chloride involves polymerizing vinyl chloride. Vinyl chloride is a known carcinogen and has other negative health effects. Its escape into the environment is a concern. Other ingredients in vinyl flooring vary widely, and some are harmful.
The thickness of the sheet and the wear layer determines the durability of the floor; unlike linoleum, vinyl flooring is usually not homogeneous, and once it wears through the print layer, it will be obviously damaged. Thinner floors may also tear. While it is possible to wax or otherwise resurface vinyl floors, it is not often done.
Vinyl floors can be recycled, but currently almost never are. They are landfilled rather than used as raw materials in a closed loop. Vinyl floor's life cycle environmental impact is worse than that of linoleum. [8]
Landfilled vinyl can leach phthalates (commonly added to flooring for flexibility).
Incinerated vinyl produces polychlorinated dibenzodioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs), dioxins, and other toxic chemicals. It can produce polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs), especially at higher temperatures.
Vinyl flooring decomposes and releases toxic gasses, mostly hydrogen chloride, long before bursting into flames. This can kill fire victims and firefighters working without a SCBA. Vinyl fires are also hard to extinguish, due to the impermeability of vinyl.
As it does not let water through, sheet flooring is suitable for kitchens and bathrooms. Some types can be used in wet rooms.
Because the closed-cell foam backing of vinyl sheet can be varied, it can be given the resilience profile of sprung performance floor, suitable as a sports or dance floor. It can make a permanent or portable dance floor which can be laid on problematic surfaces such as concrete.
Some sheet vinyl flooring can be used outside.
Sheet vinyl flooring should be allowed to rest in the room it will be installed in, to avoid having to make multiple cuts as it relaxes. Any unevennesses in the subfloor will show through the sheet flooring, so they must be smoothed in advance.
Bathtub floors may join the sheet flooring to the wall after bending it up the wall like skirting-board. As the vinyl is impervious, they help avoid water infiltration into the subfloor, and are most common in wetrooms. Sheet flooring may also be used with conventional skirting board, in imitation of rigid flooring. A concealed bathtub floor may be hidden behind skirting board (if the lower part of the back of the skirting board is cut away) or under a built-in cabinet. This also decreases the precision with which the sheet must be cut.
The flooring may be glued down over its entire area, glued down only around the edges, or unglued, depending on the area. Depending on the size of the room and sheet, seams may need to be sealed. Vinyl flooring may also be sealed to a waterproof wall surface to make a wetroom.
Hot air weld guns with plastic welding rods are often used to fix vinyl flooring in place. This is done by feeding a welding rod into the weld gun nozzle and heating the vinyl and the welding rod along the gap between two vinyl tiles.
Vinyl sheet flooring is usually made with skeuomorphic patterns that imitate wood, stone, or tile. The texture of these materials is imitated using embossing and specific top coats; the appearance is duplicated using a print layer. Recent improvements in printing technology have made for higher-resolution images.
A minority of sheet vinyl is printed with non-skeuomorphic designs; these may be drawn images resembling carpet patterns, or be photographic images such as rippled water, sand, or nebula images.
Printable sheet vinyl flooring is now also available; it can be custom-printed by the manufacturer with any image file. This allows customization of the pattern to the dimensions of the room, and can include cutting lines for easy installation.
Polyvinyl chloride (alternatively: poly(vinyl chloride), colloquial: vinyl or polyvinyl; abbreviated: PVC) is the world's third-most widely produced synthetic polymer of plastic (after polyethylene and polypropylene). About 40 million tons of PVC are produced each year.
A floor is the bottom surface of a room or vehicle. Floors vary from simple dirt in a cave to many layered surfaces made with modern technology. Floors may be stone, wood, bamboo, metal or any other material that can support the expected load.
Flooring is the general term for a permanent covering of a floor, or for the work of installing such a floor covering. Floor covering is a term to generically describe any finish material applied over a floor structure to provide a walking surface. Both terms are used interchangeably but floor covering refers more to loose-laid materials.
A decal or transfer is a plastic, cloth, paper, or ceramic substrate that has printed on it a pattern or image that can be moved to another surface upon contact, usually with the aid of heat or water.
Lamination is the technique/process of manufacturing a material in multiple layers, so that the composite material achieves improved strength, stability, sound insulation, appearance, or other properties from the use of the differing materials, such as plastic. A laminate is a layered object or material assembled using heat, pressure, welding, or adhesives. Various coating machines, machine presses and calendering equipment are used.
Linoleum is a floor covering made from materials such as solidified linseed oil (linoxyn), pine resin, ground cork dust, sawdust, and mineral fillers such as calcium carbonate, most commonly on a burlap or canvas backing. Pigments are often added to the materials to create the desired color finish. Commercially, the material has been largely replaced by sheet vinyl flooring, although in the UK and Australia this is often still referred to as "lino".
In architecture, a baseboard is usually wooden, MDF or vinyl board covering the lowest part of an interior wall. Its purpose is to cover the joint between the wall surface and the floor. It covers the uneven edge of flooring next to the wall; protects the wall from kicks, abrasion, and furniture; and can serve as a decorative molding.
Laminate flooring is a multi-layer synthetic flooring product fused together with a lamination process. Laminate flooring simulates wood with a photographic appliqué layer under a clear protective layer. The inner core layer is usually composed of melamine resin and fiber board materials. There is a European Standard No. EN 13329:2000 specifying laminate floor covering requirements and testing methods.
Ethylene-vinyl acetate (EVA), also known as poly(ethylene-vinyl acetate) (PEVA), is a copolymer of ethylene and vinyl acetate. The weight percent of vinyl acetate usually varies from 10 to 50%, with the remainder being ethylene. There are three different types of EVA copolymer, which differ in the vinyl acetate (VA) content and the way the materials are used.
Underlay may refer to flooring or roofing materials, bed padding, or a musical notation.
Vinyl composition tile (VCT) is a finished flooring material used primarily in commercial and institutional applications. Modern vinyl floor tiles and sheet flooring and versions of those products sold since the early 1980s are composed of colored polyvinyl chloride (PVC) chips formed into solid sheets of varying thicknesses by heat and pressure. Floor tiles are cut into modular shapes such 12-by-12-inch squares or 12-by-24-inch rectangles. In installation the floor tiles or sheet flooring are applied to a smooth, leveled sub-floor using a specially formulated vinyl adhesive or tile mastic that remains pliable. In commercial applications some tiles are typically waxed and buffed using special materials and equipment.
Vinyl banners are a form of banners made of vinyl. The most commonly used material is PVC. Most banners are now digitally printed on large format inkjet printers which are capable of printing a full color outdoor billboard on a single piece of material. They are used for outdoor advertising.
Damp proofing in construction is a type of moisture control applied to building walls and floors to prevent moisture from passing into the interior spaces. Dampness problems are among the most frequent problems encountered in residences.
A cement board is a combination of cement and reinforcing fibers formed into sheets, of varying thickness that are typically used as a tile backing board. Cement board can be nailed or screwed to wood or steel studs to create a substrate for vertical tile and attached horizontally to plywood for tile floors, kitchen counters and backsplashes. It can be used on the exterior of buildings as a base for exterior plaster (stucco) systems and sometimes as the finish system itself.
Wood flooring is any product manufactured from timber that is designed for use as flooring, either structural or aesthetic. Wood is a common choice as a flooring material and can come in various styles, colors, cuts, and species. Bamboo flooring is often considered a form of wood flooring, although it is made from bamboo rather than timber.
A floating floor is a floor that does not need to be nailed or glued to the subfloor. The term floating floor refers to the installation method, but is often used synonymously with laminate flooring. It is applied now to other coverings such as floating tile systems and vinyl flooring in a domestic context.
A solid ground floor consists of a layer of concrete, which in the case of a domestic building will be the surface layer brought up to ground floor level with hardcore filling under it.
Sustainable flooring is produced from sustainable materials that reduces demands on ecosystems during its life-cycle. This includes harvest, production, use and disposal. It is thought that sustainable flooring creates safer and healthier buildings and guarantees a future for traditional producers of renewable resources that many communities depend on. Several initiatives have led the charge to bring awareness of sustainable flooring as well as healthy buildings. Below are examples of available, though sometimes less well-known, eco-friendly flooring options. The Asthma and Allergy Foundation of America recommends those with allergies to dust or other particulates choose flooring with smooth surfaces – such as hardwood, vinyl, linoleum tile or slate.
Self-leveling concrete has polymer-modified cement that has high flow characteristics and, in contrast to traditional concrete, does not require the addition of excessive amounts of water for placement. Self-leveling concrete is typically used to create a flat and smooth surface with a compressive strength similar to or higher than that of traditional concrete prior to installing interior floor coverings. Self-leveling concrete has increased in popularity as the degree of flatness and smoothness required for floor covering products has increased, with vinyl goods becoming thinner and floor tiles becoming larger, for example.
PVC clothing is shiny clothing made from the plastic polyvinyl chloride (PVC). PVC plastic is often called "vinyl" and this type of clothing is commonly known as "vinyl clothing". PVC is sometimes confused with the similarly shiny patent leather.
