Cost Comparison - Porotherm vs Other Construction Materials

Wall Comparison Sheet – Costings per square metre face wall area based on retail (Rawlinson’s)

This is a base construction price only for a finished wall including materials & labour. The final cost will be subject to design complexity and contractor charges based on geographical area. 2018 Estimates based on Waikato/Auckland – New Zealand.

Porotherm Thermal Training
PowerPoint Presentation to the right outlines the basic principles of the thermal technology of Porotherm clay blocks. While this is in English, it is primarily directed to a French audience – however, the wall construction blocks are used worldwide.
This thermal report has been conducted by Thermal & Acoustic Engineer, Lubos Krajci of Soundtherm. He has a PhD in Civil Engineering and is a Member of the Passive House Institute of New Zealand.
DRYFIX versus Mortar
The Future of construction has arrived.

Widely accepted in Europe for nearly a decade, POROTHERM DRYFIX SYSTEM is a technologically advanced building system that improves productivity, saves costs and water, and paves the way for the faster building of walls. It also ensures minimum use of scarce resources and a cleaner and healthier working environment.
DRYFIX, when used with POROTHERM clay blocks (which are 60% lighter, possess high compressive strength and provide high thermal insulation) forms a combination with unparalleled benefits.
