Why build in fibrous cement?

Specification                             Brick veneer /full brick          Fibrous cement extrusion
Thermal resistance (m2K)/W
Thermal mass









To construct a thermal envelope (a climate shell) by automation of machines that;

1. Is long lasting, enduring. Can withstand high wind speeds, heavy rainfall, snowfall,  hail, earthquakes, and wind driven projectiles and temperature extremes.

2. Thermal comfort, toxicity –  envelope with high thermal coefficient and use of interior thermal mass to provide thermal inertia.

3. Indoor air quality – breathing walls – moisture control – ventilation

4. Energy efficient low heat loss.

5. Cost effective, zero or low capital borrow plan

6. Let the sunlight in.

7. security / privacy

8. interior free of constraints free to change floor plan
