Source: Lindner product data sheet NORIT-TE 20/25 (DB_N_TE_20_25/D/2.1). Sound insulation and fire resistance depend on the complete floor build-up and are therefore not listed in this table; ask for advice on your build-up.
Dry, clean, free of grease and without defects. Fill height differences with a dry fill of expanded clay or a bonded fill.
Let the boards adjust to the site temperature for 2 days before laying them.
Along all walls and adjoining building elements. PE foam, stone wool or an alternative, depending on the requirements.
Only up to class W1-I and with suitable waterproofing.
These requirements apply to the whole build-up. Ask for advice if your project has specific requirements.
NORIT-TE 20 lies on the underfloor heating as the screed. Underneath, you choose a NORIT-TE Therm GF element or a dry-build underfloor heating system such as JUPITER IDEAL. We are happy to discuss which route suits your project.
The heating layer is a NORIT-TE Therm GF element, for example NORIT-TE 25 Therm GF. NORIT-TE 20 goes on top as the load-distributing screed.
The heating layer is a dry-build underfloor heating system, such as JUPITER IDEAL. NORIT-TE 20 goes on top as the load-distributing screed.
It is also possible without an extra screed: a NORIT-TE Therm GF element is then screed and underfloor heating in one. Build-up height, heat output and control depend on the complete system. Ask for advice for your project.
Tools: hand-held circular saw with guide rail, jigsaw for curves and cut-outs, NORIT-TE adhesive, tapping block, hammer and pull bar.
Including approx. 10 % cutting waste: area × 1.1 ÷ 0.72.
Approx. 2 pallets (60 boards per pallet)
Averages: approx. 1 m of edge insulation per m² and 1 bottle of adhesive per approx. 40 m². The actual quantity depends on the shape of the room.
Order in the JUPITER ShopYou 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.
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.
Enter your own time per screw or staple and your hourly rate. We do not fill these in for you.

Enter your time per screw or staple and your hourly rate.
Indication based on your own input. Quantities according to the installation guidelines of a common screwed gypsum fibre screed system: approx. 15 screws (spacing max. 20 cm) or approx. 19 staples (max. 15 cm) per m². Material costs for screws and staples are not included.
Yes, up to water exposure class W1-I according to DIN 18534, such as a bathroom floor in a home, with suitable waterproofing. Not under a walk-in shower with a floor drain; that falls into class W2-I.
No. You glue the boards in the groove and click them together. Screws or staples are not needed.
One board covers 0.72 m². With approx. 10 % cutting waste, calculate: area × 1.1 ÷ 0.72. For 40 m² that is 62 boards. In addition, allow on average approx. 1 m of edge insulation per m² and one 1 kg bottle of NORIT-TE adhesive per approx. 40 m².
No. The board has fire class A1 according to EN 13501-1: non-combustible.
Yes. NORIT-TE 20 then lies as the screed on a NORIT-TE Therm GF element, for example NORIT-TE 25 Therm GF, or on a dry-build underfloor heating system such as JUPITER IDEAL. A Therm GF element can also be used without an extra screed; it is then screed and underfloor heating in one. Ask us for advice on the build-up that suits your project.
Three: NORIT-TE 20 Therm GF (pipe 12 mm, push-fit joint), NORIT-TE 25 Therm GF (pipe 16 mm, push-fit joint) and NORIT-TE 30 Therm GF (pipe 12 mm, click joint).
Yes. NORIT-TE 15 is 15 mm thick and has a push-fit joint. NORIT-TE 25 is 25 mm thick and has a click joint. The right thickness depends on your build-up; feel free to ask for advice.
