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.
Laminate floors are reasonably easy for a DIY homeowner to install. Laminate flooring is packaged as a number of tongue and groove planks - these 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 small beading trims can be fitted to the baseboards. Saw cuts on the planks are usually required at edges and around cupboard and door entrances.
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.
The North American Laminate Flooring Association (NALFA) is a trade association of laminate flooring manufacturers and laminate flooring manufacturer suppliers in the United States and Canada. It is a standards developing organization accredited by the American National Standards Institute (ANSI) to develop voluntary consensus standards for laminate flooring materials, and it has established testing and performance criteria that are used in North America.
NALFA issues a certification mark named the NALFA Certification Seal which signifies that the product has passed 10 performance tests, has been proven to meet these standards by an independent, third-party testing lab, and has been manufactured in North America. The certification review includes:
1. Static Load – Measures the ability of laminate flooring to resist residual indentation resulting from a static load.
2. Thickness Swell – Measures the ability of laminate flooring to resist increase in thickness after being exposed to water.
3. Light Resistance – Measures the ability of laminate flooring to retain its color when exposed to a light source having a frequency range approximating sunlight through window glass. It is not intended to show the resistance to continuous exposure to outdoor weathering conditions.
4. Cleanability and Stain Resistance – Measures both the ease of cleanability and stain resistance of laminate flooring to common household substances.
5. Large Ball Resistance – Measures the ability of laminate flooring to resist fracture due to impact by a large diameter ball.
6. Small Ball Resistance – Measures the ability of laminate flooring to resist fracture due to impact by a small diameter ball.
7. Water Resistance – Measures the ability of the surface of laminate flooring to resist abrasive wear through the décor layer.
8. Dimension Tolerance – Measures the dimensional variance between tiles of laminate flooring in a manufactured free standing (unrestricted) shape in respect to thickness, length, width, straightness and squareness.
9. Castor Chair Resistance – Specifies a method for determining the change of appearance and stability of a laminate floor, including joints, under the movement of a castor chair.
10. Surface Bond – Measures the force required to delaminate or split away the surface of laminate flooring plank or tile.
Potential health effects and LEED status
Laminate flooring is often made of melamine resin, a compound made with formaldehyde. The formaldehyde is more tightly bound in MF than it is in Urea-Formaldehyde, reducing emissions and potential health effects. Thus LEED v2.2's EQ Credit 4.4 precludes the use of UF, but allows the use of MF.
Laminated flooring is commonly used in LEED residential and commercial applications.
Laminate flooring was invented in 1977 by the Swedish company Perstorp, 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. Perstop spun off its flooring division as the separate company named Pergo, now a subsidiary of Mohawk Industries. 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 and released in 1997.
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.
The first benefit is that you can fit several rooms worth of laminate floors into a single car load. Enabling you to effectively do all your floor shopping in one go. They come in handy packets of around a metre squared meaning that a lot of them can fit in even the smallest car, leading to just the solitary trip to B&Q on a Sunday morning.
A second benefit, as mentioned earlier, is the versatility of the flooring. As laminate is a printed strip of vinyl over a wooden board, you can simulate pretty much every texture of hard wood flooring out there. It gets even better than that though, with the latest developments in laminate printing, you can now simulate a wide variety of stone patterns as well as wood. Another is that these advanced developments have also increased so much that textures can be printed on the surface to replicate not only the look of hardwood, but the feel of hardwood too.
Thirdly, as the wearing surface of the laminate flooring is generally smooth, this makes cleaning them very easy. First of all, a quick sweep will get rid of all surface materials such as dust and stray hairs. After that a simple mop and bucket job with nice, hot, soapy water will clean up any dirt that’s left stuck to your floors.
Finally, and probably one of the biggest advantages so far is the installation. No messing around with the ripping up of old floorboards to then install the new ones. Laminate flooring is like on big puzzle in the way that it all just clicks together. You simply have to slide the pieces together and you have your brand new laminate flooring.
