Our manufacturing process combines heat and pressure to form a solid panel core. A natural polymer in the straw fibre is extracted during this process and acts as a natural binding agent. A water based PVA glue is used to cover the panel in recycled Kraft liner paper. No additional chemical binding agents, glues or resins are added during the manufacturing process. The process also requires no water or gas and produces zero toxic waste. Plus, Durra Panel can be reused or composted at the end of its lifespan, making it one of the world’s most sustainable and eco-friendly building materials.
Durra Panel has an embodied energy content of only 12.6 MJ/m² throughout its entire manufacturing process. In addition, the straw it is made from grows quickly, making it an easily replenished resource. On the other hand, a stud and plaster wall has an embodied energy content of 153 MJ/m² and the timber used takes thirty years to grow, putting much greater drain on resources.
To explain that in practical terms, it takes seven acres of straw to build a standard three-bedroom house with Durra Panel and that straw will regrow in a year as a by-product of harvesting wheat or straw. The 44 trees used in a typical stud-and-plaster-wall house on the other hand requires the clear felling of around half an acre of forest and takes around 30 years to regrow.
