The oldest building material in the world in its most modern form

Clay is a gift of nature. Over thousands of years, people have used clay for healthy construction techniques - until it was almost completely replaced by industrial building materials.

With Lemix®, the advantages of clay as a building material are introduced to drywall construction as a light-weight and fast construction method for the 21st century. With the precision and quality of the first industrially produced clay panel. Lemix® is a modern clay panel for interior construction and can be used in the same way as conventional plasterboard.

Lemix® is ecological, perfectly suitable for biological building and compostable.

Healthier living with Lemix®
made of natural, locally sources raw materials
stores heat in winter, protects from heat in summer
ensures perfect regulation of the room temperature and a comfortable indoor climate
regulates the air humidity and therefore protects against mould
allows water vapour to permeate and is therefore also suitable for wet rooms in residential buildings
neutralises air pollutants
absorbs odours
provides particularly good sound insulation due to its high bulk density
non-flammable
does not release any harmful gases
is sustainable as it is compostable and 100% recyclable
Simple planning and building with Lemix®
The latest generation of clay panels
is the ideal dry construction solution for interior construction in timber and masonry houses and for the renovation (also of listed half-timbered houses, for example)
offers creative freedom to planners and architects
is manufactured in automated plants, in a primary energy- and resource-saving way
has high mechanical strength due to jute fabric backing
provides high dimensional accuracy and improved edge formation
ensures shorter assembly times by reducing the need for complex levelling layers or delicate bonding points

Lemix®. There's no easier way.

Easy to set up. No complex levelling layers. No delicate bonding points.

Especially in older buildings, the substructure often is undulated and uneven. It makes work hard when using wet plasters.
Not so with Lemix®.
Complex levelling layers are not necessary here. The wooden slats comprising the substructure are not only used for fastening the clay panels - they also compensate for any unevenness.

Lemix® is excellently suited for the cladding of interior insulations

Interior insulation is a very sensitive system in terms of building physics, but often the only way to achieve modern insulation standards. The high storage mass and the moisture-regulating properties of clay building materials complement the insulating materials perfectly.
With Lemix®, such insulation can be easily and safely clad.

Also as dry plaster board - a fine thing

Clay panels can also be used as dry plaster slabs. They are glued to flat surfaces which must be dry, solid, dust-free and clean. Usually a mortar or adhesive bed is used over the full surface.
