Porotherm Clay Blocks for Exterior Walls
Under the brand Porotherm, Wienerberger offers a qualitatively optimized, complete system.

The monolithic external wall
Consists of just one wall construction material (other than plaster and mortar). Here, the Porotherm clay block fulfils the requirements for thermal insulation, sound insulation, fire protection and static as well as ensuring a pleasant indoor climate.
The Cavity Wall with Facing Bricks
This type of cabity wall is one of the most important external wall constructions in many European countries.
The logical separation of the external wall by function into:
- A load-bearing clay block wall
-
A thermal insulation layerwith a ventilated cavity
- A facade made from facing bricks
This allows the outstanding properties of the load-bearing clay block wall and the facing bricks to be fully exploited.

The Cavity Wall with Plaster Facade
In this type of cavity wall construction, the façade is not made of facing bricks, but of rendered 100mm, 140mm or 190mm Porotherm clay blocks.
An External Wall with Additional Thermal Insulation
An additional layer of thermal insulation is applied externally to a load-bearing Porotherm clay block wall. In a construction with additional heat insulation, the Porotherm clay block takes over not only the static functions, but also those of sound insulation and heat storage.
Porotherm - load bearing and non load bearing inner walls
The ideal combination of optimal fire and sound protection as well as high thermal insulation.
