PRINETO Knobbed Board
The PRINETO knobbed board is your first choice for quick and clean laying. It allows surface heating systems to be installed without the use of tools and two different insulation thicknesses ensure the right standard-compliant insulation. Our tip for extremely low floor structures: the PRINETO knobbed board without insulation
- Clean and tool-free laying
- Side overlap to prevent the ingress of screed water
- Foam, dimensionally stable knobs
- Laying spacing of 5 cm or 7cm (diagonal)
- Underlay 11 and 30 mm
- Also available as knobbed foil without underlay
Here's how it's done!
Lay the knobbed boards in all rooms so that the backing of the edge insulating strip is positioned on the knobs.
If a new board is used for laying, first cut off the protrusions on the knobbed foil on the wall sides.
Join the necessary knobbed boards by overlapping with the previous knobbed board.
Lay the PRINETO levelling board (without profile) instead of the knobbed boards before the heating circuit manifold and in all areas with expansion joints
In doorways and between the heating circuits, adhere the self-adhesive PRINETO expansion joint profile to the surface of the levelling board
Then flush every heating circuit with water and vent and also perform a pressure test for connected heating circuits.
Pay attention to the assembly instructions in our technical documentation!
