The beauty of Porotherm is that it is a permeable, breathable and permanent clay block construction system — it doesn’t need any pre-cladding to perform at the highest level of moisture management and protection. Being a fully self-sustaining construction system designed to perform every function required in a wall, Porotherm will out-perform and out-last any other pre-cladding system on the market simply by way of its design, functionality and materials.
Porotherm clay blocks exceed the NZBC performance requirements, with the block and building wrap being one and the same. Porotherm blocks are extremely durable and are guaranteed for a minimum of 150 years — exceeding standard timber frame construction.
The matrix of Porotherm being engineer-designed to manage moisture, heat/cool and remain stable for many generations means there is no possibility of deterioration or necessity to be replaced due to rotting caused by moisture. If the cladding or finish of the building fails, there is no concern about the pre-cladding as the wall is already stable and inert.
Porotherm Clay Block construction is dubbed "one wall that does it all" for this very reason. Building with Porotherm means there is never any concern about what is going behind the walls because Porotherm forms the entire wall.
