Material and environment

90–96 % gypsum
and 4–10 % cellulose fibres; both recycled from production processes (pre-consumer)
5.05 kg CO₂-eq/m²

Installation

Tools: hand-held circular saw with guide rail, jigsaw for curves and cut-outs, NORIT-TE adhesive, tapping block, hammer and pull bar.

  1. 1Let the boards acclimatise on site for 2 days and fit edge insulation along all walls: PE foam, stone wool or an alternative, depending on the requirements.
  2. 2Apply NORIT-TE adhesive in the groove. At 20 °C the adhesive remains workable for about 30 minutes.

What do you save without screws or staples?

You glue NORIT-TE boards and click or push them together. A common screwed gypsum fibre screed system adds approx. 15 screws or approx. 19 staples per m². Work out for yourself what that saves in your project.

Less work, only gypsum fibre in the floor

No screws or staples. You do not need to buy, count or drive them.

Less finishing work. According to Lindner, there is less filling and rework before the floor finish goes on.

No metal in the floor. If the floor is sawn or milled later, the tools do not hit any screws or staples. The floor contains only gypsum fibre boards and cured adhesive: PU adhesive (NORIT-TE adhesive) or PVAc adhesive.
