CHILL, IT’S ALL GOOD: Peter Cuming and Eshana Bragg outside their Maclean home, which will soon be extended with walls built with hemp, sand and lime.
“We were looking for a building material that would be really sustainable; that actually had something special about it.”
Ms Bragg said the hemp, sand and lime mixture provided good sound, heat and cold insulation.
The hemp is the consistency of chaff and cures and sets like concrete when mixed with sand and lime and a few other special ingredients.
Over time, as the walls cure, the hemp walls absorb carbon dioxide.
“It’s like the perfect building material to help stop climate change,” said Ms Bragg.
