Hemp & Clay – The Evolution in Drywall Construction
Strong, lightweight, future-proof
Building with the lightweight conluto hemp clay building boards is the modern answer for interior fit-out with clay. The boards are dimensionally precise, extremely stable in shape and yet surprisingly light. Thanks to the combination of strong hemp fibres and the finest clay, the board is easy on your strength to handle and work. The conluto system guarantees you that all components – from the board to the finish – interlock perfectly.
Goodbye gypsum dust, hello well-being
Say goodbye to grey gypsum dust and pungent odours. You will notice the difference as soon as you start installing the lightweight hemp clay building boards: the subtle, natural scent of the hemp shives creates a pleasant working atmosphere. Whereas plasterboard often makes rooms feel "dead" and dry, this board can absorb moisture and release it again as soon as it is installed. A clay building material that can buffer fluctuations in indoor air humidity and is easy to work with from the very first moment on site.

Hemp-clay building board for interior fit-out
The 14 mm boards are screwed or stapled as plaster base boards onto a continuous substrate or a substructure with 31.25 cm grid spacing.
The 22 mm board can be installed on a continuous substrate or on a substructure with 62.5 cm grid spacing.
Both boards can be installed on walls, ceilings and sloping ceilings. The subsequent plaster build-up is: conluto clay adhesive and reinforcing mortar with full-surface mesh, followed by a fine-mesh finish (decorative finishing plaster, smoothing coat or clay paint).
Alternatively, you can also use wall and ceiling primer, base coat plaster up to 15 mm with mesh and finishing plaster on top.
Hemp & Clay: Efficient Drylining with Natural Building Materials
The lightweight hemp clay building board combines the easy handling of modern dry-lining construction with the moisture-buffering properties of clay as a building material. It is the ideal, weight-optimised solution for fast interior fit-out that meets high demands on surface quality.
