Bio-aggregate: hemp-lime, resolves moisture issues whilst also having the beneficial effect of improving the thermal efficiency of older buildings. The principles and materials used in traditional construction methodology prevent degradation whilst regulating temperature and humidity by capturing energy from moisture.
Improved loft insulation and double glazing make walls the coldest surface in the room, increasing the risk of condensation. External insulation is costly, complex, unsympathetic and retrofitting leave cold spots internally. Walls insulated internally with foam board lose the capacity to buffer temperature and humidity causing interstitial condensation. Bio-aggregate: hemp-lime is more than wall insulation reducing heat transfer through a wall, it also improves air tightness, has more accessible thermal inertia, and an increased surface temperature to improve thermal comfort. Retrofitting from cold and damp to warm and dry.
Up to date information on research, process and training are now hosted here…
The following case studies document early prototyping of the process.
The damp Victorian terrace, built on a budget, what went wrong and what made it worse? How a century of bad practice was put right in a couple of weekends.
The steamy bathroom, need to be more than breathable, capacity counts, rapidly responding in layers, the wallpaper’s not for decoration.
The open plan kitchen, wreaking havoc in every home, enter the Bi-folding doors and the reveals expose a concentration of moisture.
Every home has Cold spots under repeated attacked from internal-weather, reduce the storms by tackling a more manageable project in isolation.
