However, there are several properties of the material that makes it much more useful in modern contemporary construction than might initially be thought. Unfired clay based plasters are very good at absorbing atmospheric humidity and can do so at a rate that makes them useful in areas with fluctuating high moisture levels, such as bathrooms and kitchens.

Understanding A Building's Thermal Performance Using U-values


The U-value of a building element, such as a wall, roof or floor, is a measure of the thermal transmittance of that element. The lower the U-value, the slower the flow of heat is through that element once it has reached a steady state (meaning the flow of heat through...
