Laminate flooring (also called floating wood tile in the United States) is a multi-layer synthetic flooring product fused together with a lamination process. Laminate flooring simulates wood (or sometimes stone) with a photographic applique 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.

Laminate flooring has grown significantly in popularity, perhaps because it may be easier to install and maintain than more traditional surfaces such as hardwood flooring. It may also have the advantages of costing less and requiring less skill to install than alternative flooring materials. It is reasonably durable, hygienic (several brands contain an antimicrobial resin), and relatively easy to maintain.

Installation

Laminate floors are reasonably easy for a DIY homeowner to install. Laminate flooring is packaged as a number of tongue and groove planks, which can be clicked into one another. Sometimes a glue backing is provided for ease of installation. Installed laminate floors typically “float” over the sub-floor on top of a foam/film underlayment, which provides moisture- and sound-reducing properties. A small (1–10 millimetres (0.039–0.394 in)) gap is required between the flooring and any immovable object such as walls, this allows the flooring to expand without being obstructed. Baseboards (skirting boards) can be removed and then reinstalled after laying of the flooring is complete for a neater finish, or the baseboard can be left in place with the flooring butted into it, then small beading trims such as shoe moulding or the larger quarter-round moulding can be fitted to the bottoms of the baseboards. Saw cuts on the planks are usually required at edges and around cupboard and door entrances, but professional installers typically use door jamb undercut saws to cut out a space to a height that allows the flooring to go under the door jamb & casing for a cleaner look.

Improper installation can result in peaking, in which adjacent boards form an inverted V shape projecting from the floor, or gaps, in which two adjacent boards are separated from each other.

Care

It is important to keep laminate clean, as dust, dirt, and sand particles may scratch the surface over time in high-traffic areas. It is also important to keep laminate relatively dry, since sitting water/moisture can cause the planks to swell, warp, etc., though some brands are equipped with water-resistant coatings. Water spills aren’t a problem if they’re wiped up quickly, and not allowed to sit for a prolonged period of time.

Adhesive felt pads are often placed on the feet of furniture on laminate floors to prevent scratching.

Inferior glueless laminate floors may gradually become separated, creating visible gaps between planks. It is important to “tap” the planks back together using the appropriate tool as gaps are noticed in order to prevent dirt filling the gaps, thus making it more difficult to put into place.

Quality glueless laminate floors use joining mechanisms which hold the planks together under constant tension which prevent dirt entering the joints and do not need “tapping” back together periodically.

History

Laminate flooring was invented in 1977[citation needed] by the Swedish company Perstorp [en], and sold under the brand name Pergo. They had been making floor surfaces since 1923. The company first marketed its product to Europe in 1984, and later to the United States in 1994. Perstorp spun off its flooring division as the separate company named Pergo, now a subsidiary of Mohawk Industries.[5] Pergo is the most widely known laminate flooring manufacturer, but the trademark PERGO is not synonymous for all laminate floors.

Glueless laminate flooring was invented in 1996 by the Swedish company Välinge Aluminium (now Välinge Innovation) and sold under the names of Alloc and Fiboloc. However, a system for holding flooring panels together was also developed in parallel by the Belgian company Unilin released in 1997 and sold under the name of Quick-Step flooring [nl].

The two companies have been in a great number of legal conflicts over the years, and today most, if not all glueless locking flooring is made under license from either Välinge, Unilin, or even a combination of both.
