Monolithic clay block system

Precision engineered clay blocks

As a natural clay product, Porotherm blocks are safe and non-harmful for use in any housing project, and when plastered they can achieve excellent air tightness and thermal performance. The Porotherm Monolithic system gives you the ability to construct a water-tight structure by taking the external leaf off critical path, where appropriately designed.

Porotherm Monolithic is a product system that provides a solid wall construction. The blocks are thicker and can be used in place of the usual cavity system, meaning there are no cavity blocks required. The blocks can be finished with render or brick slips.
