Wet areas (bathrooms)


The Austrotherm UNIPLATTE board is an ideal carrier, in new buildings and in renovations alike. It is recognisably pink, made of extruded polystyrene foam (XPS), and reinforced on both faces with a glass-fibre mesh embedded in a special mortar. It is made in Austria (Pinkafeld).
Austrotherm Uniplatte (4, 6, 10, 20, 30, 40, 50, 60, 70, 80, 100 or 120 mm thick, in 600 mm x 1300 mm or 600 mm x 2600 mm) is an ideal carrier for ceramic tiles. Very easy to cut and install, it has many uses: floors, partition walls, boxing in services, cabinets, shelves, steps and more.

| Thickness in mm | Applications |
|---|---|
| 4*, 6*, 10 | As a levelling board in bathrooms whose walls are not tiled to full height. Old tiles are often only 4 mm or 6 mm thick; this allows new tiles to be laid on the whole wall, up to the ceiling. |
| 12.5 | Plasterboard is often used in wet areas (e.g. bathrooms). Our 12.5 mm board is then the ideal connecting board between two plasterboards, whose standard thickness is also 12.5 mm. |
| 20, 30, 40, 50 | As a structural solution for all kinds of tasks. In the bathroom: boxing in pipes, cladding furniture (shelves, cabinets, small tables etc.), partitioning services, etc. |
| 60, 70,,80 | As a structural solution for all kinds of tasks. In the bathroom: wherever high stability is needed — heavier bathroom furniture, steps, etc. |
| 100.120 | As a structural solution for all kinds of tasks. On balconies: wherever high stability is needed, e.g. free-standing partition walls. |
*These boards measure 1300 mm x 600 mm. Boards with d ≥ 10 mm measure 2600 mm x 600 mm.

With a suitable saw you can cut all kinds of shapes from Austrotherm Uniplatte, including round and oval ones.

The adhesive bonds perfectly to screed or concrete. If the substrate is not load-bearing, Austrotherm Uniplatte must be fixed to it with dowels.
Insulation advisor
Describe the job — get the right boards
Tell us what you are insulating and with what. The advisor picks from Austrotherm products only and quotes our own data; the site then works out the packs.
- Describe the building element and the situation
- Get the element, the boards and the open questions
- Calculate packs and the indicative thickness
Indicative calculation
How many packs?
Packs from our own packing lists: area ÷ m² per pack, rounded up. With a target U-value the calculator shows the indicative insulation thickness d = λ × R.
Enter the area to see the number of packs.
Indicative only — the final choice and thickness are confirmed by your designer or Austrotherm technical support. The thickness estimate takes the insulation layer alone (R = 1/U) and does not check any regulation.
