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 (often also referred to as “clay building slab”). 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®
Simple planning and building with Lemix®
The latest generation of clay panelsLemix®. 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.
