You’d be a dope not to consider ‘hempcrete’

WHILE cannabis, aka hemp, has a long history as a fibre used in ropes, sails and paper products, a small number of entrepreneurs have found a novel application for it as a form of insulation

WHILE cannabis, aka hemp, has a long history as a fibre used in ropes, sails and paper products, a small number of entrepreneurs have found a novel application for it as a form of insulation.

Hempcrete is made using the woody, balsalike interior of the cannabis sativa plant mixed with lime and water.

Though it lacks the structural stability its name might suggest, hempcrete does provide natural insulation that is airtight yet breathable and flexible. It is also free from toxins, impervious to mould and pests, and virtually fireproof.

“I know, I know, everyone talks about our buildings going up in smoke, but the joke is on them,” said one hempcrete entrepreneur, Mr. Savage, who is keen to point out that hemp is not a drug.
