Raised Floor NORTEC

Ongoing comfort.

The NORTEC raised floor system offers impressive in-built properties and truly state-of-the-art technology. It is the ideal product for almost any field of application.

NORTEC floor panels give superb underfoot comfort. They are manufactured from calcium sulphate (gypsum): a non-combustible material with superlative structural and physical properties. This product also offers outstanding levels of soundproofing. As a manufacturer, we can determine the choice of raw materials used.

The Institute of Building Biology in Rosenheim recommends NORTEC as a biologically-neutral building material. Our gypsum panels are virtually emission-free.

NORTEC can be combined with many other systems, offering a great degree of flexibility. There is also a practically limitless choice of floor coverings.

Product features: 

  • Superb underfoot comfort
  • Very high loadability
  • Non-combustible
  • Simple taking-out and changing of single panels
  • Low air leakage rate

The substructure is an important component of every system floor. The pedestals create the cavity needed to accommodate the services. Lindner metal pedestals can be adjusted to almost any height, therefore compensating for any uneveness in the subfloor.

From design to manufacture – we produce our pedestal range entirely in-house. We manufacture highly accurate pedestals for raised floors. Our many years of experience ensure high load-bearing capacity and excellent durability for all our products.

Lindner systems can be combined with one another in many ways, and supplemented with different reinforcement profiles.

Reinforcement profiles

Even a standard Lindner floor system offers excellent load-bearing capacity. Should this prove insufficient, the system can be upgraded by reinforcement profiles, adjusted to the specific purpose.

Many options are available, from the lightest stringer which increases lateral rigidity through to a C-profile.
