Porotherm clay block projects

Versatile, fast, dry, safe and sustainable

Clay blocks can have a rendered external finish on monolithic single skin walls, or an outer leaf of facing brick in a cavity wall construction. Strong and durable, yet lighter and often less of a strain to work with than many of the alternatives, clay blocks also build-in sound and temperature control benefits wherever they are used, creating the ideal internal living environment.

Clay blocks can be used in load-bearing and nonload-bearing applications and are ideal for:

  • Inner leaf of brick-faced cavity walls
  • Inner and outer leaves of rendered cavity walls
  • Infill panels within framed structures
  • Partition walls and separating walls
  • Single leaf (monolithic) internal & external walls

The Carrowbreck meadow development in Norwich is one of the first Passivhaus certified residential projects in the area. To help achieve this Porotherm, Wienerberger’s innovative clay block walling system, was specified.

In June 2012, the Cathedral embarked on another ambitious first, announcing an £8.5 million plan to construct a Clergy Court and Cloister Garth using Wienerberger's Porotherm walling system.
