Flooring Glossary

Expertise on the subject of floor coverings with glossary and detailed advice to maintenance and functionality.

To protect floor coverings from damage and allow furniture to roll easily over floor coverings EN 12 529 specifies that Type “H“ (hard) castors should be used on textile floor coverings and Type “W“ (soft) castors should be used on resilient floor coverings. Also in accordance with the above-mentioned specification, non-rolling feet/legs on furniture and the ground contact areas of furniture must be made of "hard" materials if used on textile floor coverings and must be made of "soft" materials if used on resilient floor coverings. This means that furniture feet/legs with sliders or castors must be made of the appropriate materials and must not be sharp-edged.

Selection of the right floor covering may greatly reduce the level of effort subsequently required for routine maintenance (cleaning). Another key factor here is the visual insensitivity to dirt: with floor coverings this factor is just as important as their resistance to wear. The visual insensitivity to dirt depends on the colour, pattern and also the surface structure of the floor covering. Entrance / zonal matting or gratings should be used to prevent as little dirt as possible being brought into the building. The criteria for the selection of entrance or zonal matting in terms of size, material and positioning should be tailored to the prevailing circumstances.

Testing of our resilient floor coverings is proceeded according to European Standard EN 423 / EN ISO 26987 – determination of the effect of stains – with a 2 hours effect on the floor covering. The Standard defines the procedure and the means of evaluation. In or-der to enable a practical use of the testing procedures, the chemicals to be used in the procedure are not prescribed by the standard itself.

In terms of technical feasibility and according to VOB Part C, DIN 18365 "Floor covering work" (German: Bodenbelagarbeiten), it is not possible to manufacture floor coverings free of tolerance. This applies both within a single batch and between different batches. Nevertheless, the deviations within a single batch are lower. As a result, there is a generally accepted rule within the trade that only product from the same batch may be laid within any particular room, paying attention to the ascending/descending roll numbers of the floor covering sheets. Before laying the floor covering, it is also important to ensure that production outer edges are laid next to each other after first being manually trimmed. This is also an important criterion for the use of left-over sheets and strips.

In hospitals, old people's home, schools, nurseries etc. it must be possible to disinfect floor coverings as needed. In hospitals the prevention of infection is the most important aspect of clinic hygiene.

So small and yet so strong: the dorix® brand fibre forms the basis for the high quality of DLW’s “Strong” fibrebonded product. The synthetic fibre guarantees an extremely high level of wear resistance, rapid rebound following pressure load and a low degree of soiling. The dorix® brand fibres are dyed using a special spinneret process to ensure the greatest possible colour fastness and consistency. The overall result is an exceptionally robust, easy to clean and durable textile floor covering.

With standing fixtures such as cabinets, chairs, shelves, or similar furniture one speaks of static surface pressure. This static pressure can be calculated very simply. The total load of fixtures (in kg) is divided through the whole area of furniture legs = amount x (length in cm x breadth in cm = cm²). In practice this kind of load should not produce a surface pressure exceeding 25 kg/cm². Load-bearing capacities, e.g. from fork lift trucks, are calculated following the Hertz' formula.

Electrostatic requirements for floor covering can affect the body voltage / antistatic, the vertical resistance or the insulation to ground. These properties can be requested by users, national and international standards or equipment producers and must be described in the building declaration.

DLW Flooring has developed with PURe a next-generation lacquer system. This system is impressive in terms of technology, with its superb scratch and stain-resistant properties, and its look and feel, with an ultra-matt, top quality surface effect.

 The new lacquer technology uses an extremely precise, concentrated UV energy range which ensures that the lacquer seals and bonds much more effectively. This effect results in excellent dirt and scratch resistance.

Properties of the Scala PURe collection:

Genuine cost-savings, with lower cleaning costs and a longer lifetime thanks to
- Scratch resistance
- Stain resistance
- Ultra-matt surface
- Extremely low emissions
- Naturally free from phthalates
- Made in Germany

PURe saves on costs and resources. Its new technology guarantees that protected and unscathed surfaces will have a much longer service life. On average, similar LVT floorings need to be replace every 3-5 years due to scratches and stains, especially in exposed areas that are highly frequented by customers and visitors. Scala PURe resistant surfaces, by contrast, protect and keep them looking good as new for many more years. This also reduces maintenance costs, as there is no need to carry out an intensive clean twice a year in order to remove stains. In areas with heavy traffic, this can help reduce cleaning costs by up to 20%.

PURe’s excellent scratch protection is all down to the tiny, yet ultra-hard sapphire particles used in the lacquer system. These particles prevent scratches caused by abrasive, mechanical movements on the surface. Sapphire is one of the hardest substances known to man. This makes Scala PURe ideal for heavily used surfaces like shops, hotel entrance areas, offices and any public areas with heavy traffic.

The PURe lacquer provides much stronger sealing and bonding. As a result, it also offers excellent dirt resistance. The connection is simple: the more closed-off and sealed the material surface is, the less dirt can get in. That means the floor covering is optimally equipped against discolouring.

To demonstrate the stain resistance of PURe surface protection, we have used some of the strongest colouring agents: hair dye and iodine solutions. Traditional lacquer systems exhibit strong discolouration that cannot be removed. PURe, on the other hand, is essentially protected. In a standard test with an exposure time of two hours, the lacquer shows no signs of discolouration.

And we really put it to the test: Using PURe, the chemicals could be removed, free from residue, even after 24 hours. That means the hassle of iodine stains in the health sector or unsightly dye stains in drugstores, hair salons or even at home are now a thing of the past.

For testing and rating of the slip resistance of floor coverings in Germany there applies the guidelines BGR 181, edited by The National Association of Industrial Cooperation. This association classifies the working-areas and tests and classifies the floorcover-ings. The method for testing floor coverings is the “ramp test”. The testing device is a smooth slab. The angle of this slab can be adjusted from 0 to 45°. A sample (size 100 x 50 cm) of the floorcovering is mounted onto the slab and wetted with 100 ml of min-eral oil SAE 10 W 30. Three persons wearing safety shoes walk three times each on the test sample while the angle of the slab is changed.

The European standard EN 1307 (issued July 2014) specifies the requirements and tolerances for fibrebonded floor coverings in usage classes in relation to wear, changes in appearance and a luxury rating. It applies among other textile floor coverings to fibrebonded sheet floorings and tiles.

Standards fibrebonded floorings

For the different resilient floor coverings a seperate product standard specifies the requirements and tolerances. From January 2007 all floor coverings sold in the European Union and the CEN member states must bear the CE mark. This is however conditional on such floor coverings satisfying the essential requirements of EN 14041 and the requirements of the individual product standards.

By using the surface coating PUR+ DLW Flooring guarantees even stronger performance to all homogenous Vinyl floor coverings: improved scratch resistance and durability as well as lowered emissions. PUR+ leads to better resistance towards all influences in daily business. Even chemical resistance has been further improved. Therefore acids and alkalis, also at higher concentration, can’t do any harm to floorings. Thanks to its extraordinary cleaning characteristics, dropped chemicals can be removed easily, without doing any harm to the floor. Due to its heat-sealed welds, dirt and bacteria can’t settle down. By the same time a 100 % jointless and hygienic installation can be realized by using HSLA, a concave skirting board of 2.0 mm vinyl with reinforced aluminium backing and HPR, a synthetic rubber section for installing around the edges of the room.

The raw materials for the manufacturing of DLW Linoleum are linseed oil, resins of wood, cork- and wood-flour. These contain certain compounds which react when exposed to light: During the time needed for oxidation and protected from light they cause a yellow, green or brown shade. When you expose DLW Linoleum to light, this shade will disappear, the more intensive the light, the faster the disappearance of the shade.
