Just wondering if anyone has experience of using hemp as insulation or the latest innovation of spray on hempcrete.
I am toying with the idea of insulating my small mill conversion with spray on. An architect up the road did it and you get a wonderful natural look. Also no messing with batons and boards.
The pros seem to be:
Natural look and smell
Go as thick as you like and sticks to anything....suits uneven walls.
Similar price to other options (all in).
Suits old buildings.
Maintains R Value
Need 3 x thickness of standard insulation for same R Value.
Not as fire resistant!!
A concern with damp walls but can go on tanking....but then you lose breathability.
Requires specialist machinery that mixes the product at end of hose....so no DIY.
Not ideal I'm my small building if it has to be 250mm thick!!
