Thermal and Acoustic Advantages

What are the advantages of rammed earth walls?

Besides their striking beauty and characteristic deep reveals, rammed earth walls have outstanding thermal and acoustic benefits. They have an ideal blend of heat transfer (U Factor) and density or thermal storage (known as the "thermal flywheel" effect). This unique combination of properties creates a high thermal mass building, which evens out day/night temperature fluctuations and forms a comfortable building in which to live all year round.

Does sound transmit or echo between rooms? No, quite the opposite, rammed earth walls have good sound absorbing characteristics and can be built to have a very high sound rating (STC 57) which inhibits noise transfer between rooms extremely effectively. Common sound reverberation levels are simply not present in our buildings and visitors usually remark on the tranquil ambience of our Clients homes.

How thick are the walls? Although specialised walls can be from 200mm to over 1000mm, the standard thickness is 300mm (12") thick.
