As you may have noticed from my twitter feed I have been working on creating a breathing wall. This is for a wooden house built with cedar tiles on a timber frame. The house has cavity walls and then lath and plaster inside. I previously built a green roof on this house and we insulated it with rock wool.
For the walls we were wary of using artificial insulation because of worries about condensation. The house was built with all natural materials and it’s own way of ventilating and we didn’t want to interfere with that. With this in mind we decided to use wood fibre insulation.
First we stripped out the laths and started adding in wood fibre batts.
Then we covered these with more robust wood fibre boards.
Then yesterday I started adding lime plaster to the wall for the finishing touches.
This is the first wall and we have discovered a few things. Firstly we will need more wood fibre boards as the uneven distribution of the timber frames means you have to cut them a lot and some gets wasted. Also took a while getting used to the plastering again but my training from Paul at DIY Plastering paid off and I was soon into the swing of it. The final skim on the plaster should be done on Wednesday providing there isn’t too much moisture in the air. More updates soon.
