Our patents

CLASSEN megaloc- without doubt the fastest and easiest glueless or glue free locking system in the world today. 

Integrated in our own floosrs as "CLASSEN megaloc", other well-known laminate flooring manufacturers have also taken over this revolutionary simple quick installation system under licence.

Laminate floors have never been easier or quicker to lay as those with megaloc and this includes DIY as well as professional floor fitters who are now able to lay floors up to three times faster.

In conjunction with megaloc, issowax also offers highly effective moisture protection from above particularly in the critical joint areas.

Predecessor of the fold down locking system is the so-called angle - angle installation which under the name of easy connect is still in use today particularly in entry price point products.

Decisive for the EasyConnect patent is the special shape of the self-compensating angled joint. "EasyConnect" was registered with the European Patent Office in 2002 - as a glue-free laying system - under the EU Patent No. 1165 906. Patent registrations in the USA under US 6,505,452 B1 and a laying patent under EP 1200 690 B1 followed in 2003. The EasyConnect laying system heralded the era of glue-free laying systems.

The CLASSEN Group has not only broken new ground in terms of materials and product structure; new technical possibilities are also being used in design: The CLASSEN Group prints the entire range of healthy design and wall coverings directly and digitally during the production process. Single-pass systems from Hymmen with eight rows and 19 print heads each, which achieve a resolution of 360 dpi in the decorative image, are used for this purpose. Decor-synchronous surface embossing is also possible - using embossing rollers and directly in the digital printing process.

From manufacture to industrial digital printing for laminate flooring and design floor coverings.

The digital printing process makes production flexible in many directions. For example, laminate flooring and design floor coverings can be produced in high volumes as well as in smaller quantities.

Individual decors and colour variants can be adapted to the wishes of CLASSEN customers. Further scenarios could take the form of decor developments of the customer or those of the CLASSEN Design Centre. In this way the sales partners of CLASSEN receive individually designed floor coverings.

Digital printing opens up completely new possibilities for the CLASSEN Group and its sales partners, because from now on it is possible to react much more quickly and flexibly to new design and decor trends.

The Liquid Laminate Technology (LLT) is a patented production process of the CLASSEN Group, which is used for the laminate flooring production at the integrated site in Baruth/Brandenburg. The special features of this process are the combination of different surface finishing technologies and the merging of previously separate work steps into one production run. This offers considerable advantages in terms of product quality. At the same time, this process opens up further possibilities for energy-efficient and thus lower-emission production.

After an intensive development period, the production of laminate flooring using a new process was started at the CLASSEN Group's Baruth production site in 2009.

Up until now, the overlay, decor and backing papers necessary for the production of laminate flooring simply use are first impregnated with melamine resin in a complex and upstream process, in order to then be pressed onto carrier boards (HDF, MDF or chipboard) in a second work step using KT or double belt presses.

The "LLT process" (LLT = Liquid Laminate Technology), invented by Classen and already implemented on an industrial scale, combines these two previously completely separate work processes in one production line. In this line, the carrier boards are first covered with a decorative paper at the top and a backing paper (or decorative paper) at the bottom and then joined. Then melamine resins with the necessary additives are applied in liquid, powder or paste form to this top and bottom side and dried. The panels coated in this way are then fed into KT or double belt presses as before. In the pressing process that concludes the production process, the melamine laminate panels are cured between smooth or structured press plates or press belts and simultaneously given the desired surface structure.

The quality of the products manufactured according to this technology is fully comparable to the quality of melamine-coated panels manufactured by the conventional process, whether for flooring or furniture surfaces.

In 2010, Classen also tested a modification of this LLT process and invested in application technology for this purpose as well. This variant, known as "LLT-light", combines the advantages of a board coated with non-pre-impregnated decorative papers for further processing in conventional KT presses, thus enabling, for example, high flexibility even for smaller production batches.

The LLT process is not limited to the production of melamine-coated carrier boards. Rather, the use of other resins or even coatings is possible, so that a large number of product designs and a wide range of applications can be covered.

In order to introduce other interested parties to this low-emission production method, production licenses for this process, which is extensively protected by patents and patent applications, have been granted by a subsidiary of the Classen Group, Surface Technologies GmbH & Co. KG, based in Baruth, is in preparation.

Overall, the patented LLT process offers numerous advantages over conventional laminate flooring production methods:

  • Energy-saving production
  • Highly transparent surfaces
  • Significantly better, more realistic decor display
  • Individually pronounced gloss levels
  • Optimum appearance and feel of the laminate flooring surface

From the fine pore to the chrome-like surface structure.

By special techniques in the refinement of laminate decors with unusual surface structures CLASSEN shows highest product authority.

Beginning with smooth surfaces or those without structure to highly polished, super matt or those with the feel of an oiled surface many structure variants are available:

  • Matt and fine pore surfaces are mainly found in the entry-level price variants.
  • Tangible fine structures or matt structures complete the range of surface finishes.
  • Synchronous structure, hand-scraped surface or glossy pore form the next stage of a high-quality sensitive surface refinement.
  • Leather and cast iron as well as stone, slate and lacquer are among the extraordinary special structures and are further proof of CLASSEN's excellent surface competence.
