Introduction
Bio-aggregate: internal wall insulation – casting to existing masonry – 60 seconds
Workshop
Peer to peer on-site training, structured tuition and open format learning.
Energy-retrofitting traditional solid wall heritage properties using Bio-aggregate: construction grade hemp shiv – Cannabis Sativa, and formulated lime binder – Tradical Thermo.
Mixed by weight, at a ratio of one part shiv, one part binder and three parts water. 1:1:3. Achieving a density of – 200kg per cubic metre, (200 grams per litre) and a Thermal resistivity – Lambda (λ) value, of 0.056 W/mK.
Carbon sequestering and zero waste.

- Procurement
- Risk assessment
- Preparations
- Mixing
- Casting
- Systems thinking
- Team building
Summary
We’ll be working alongside experienced practitioners on a real project, learning how to design and plan, as well as the practical delivery.
We’ll consider the underlying objectives of the installation within the broader context of energy and moisture in the home.
We’ll look at the preparations that are required to the walls and how these affect the quality and speed of the installation.
We’ll use a small scale mixing process to accurately proportion, whether by weight or volume and how much water is required for a successful mix.
We’ll calculate the casting volumes and density before getting the project moving efficiently with a little system thinking and team building.
Lunch will be provided.
The content will be covered on days one and two, day three is optional providing an opportunity to practice, demonstrate and re-visit aspects of importance to you.
Open day

Summary
We’ll look at the underlying objectives of the installation within the broader context of energy and moisture in the home.
We’ll demonstrate the preparation, mixing and casting method as well as discuss why the process is finished with coarse and fine lime plaster and the application of lining paper and paint.
