New: weber.therm circle has also been available with wood fibre boards since March 2024. With this innovative recyclable system, builders and planners now also have the option of choosing wood fibre as an insulation material.

Wood is a building material whose "production" not only produces no CO₂, but also binds CO₂ - around one tonne of the climate-damaging greenhouse gas per cubic metre of wood. What's more, wood is a renewable raw material that constantly renews itself.

This puts wood far ahead in the life cycle assessment of various building materials. An insulation board based on wood fibre is therefore the logical further development of the sustainable weber.therm circle ETICS.


Apart from the insulation material, nothing changes in the system structure.

The processing of weber.therm circle with wood fibre also hardly differs from that with mineral wool. Here too, the insulation boards are not glued to the substrate, but simply mechanically fixed with dowels.

Weber has developed a special installation tool, which is placed on the drill, for the simple and controlled placement of the dowels together with the setting plates in the wood fibre insulation board. This allows the fasteners to be set easily and evenly.

The absence of bonding, together with the separation layer, enables the system components to be separated by type after dismantling and forms the basis for recycling. The wood fibre boards can, for example, be flocked and reused as blown-in insulation.
