›Thermal Mass The external walls of our rammed earth buildings are a minimum of 300mm (1 ft) thick, providing excellent protection from extremes in climate. The thickness and density of the material means that heat (or cold) penetration of the wall is very slow and the internal temperature of the building remains comparatively stable, with the end result of it feeling warmer in winter and cooler in summer than the outside temperature.Hb 195-2002 the australian earth building handbook.This Handbook was prepared jointly by Dr Peter Walker, University of Bath., primarily single and twostorey, buildings constructed using unbaked earthen walls and floors.

A technical book but written in an entirely accessible and entertaining way, for uninitiated builders and ‘professionals’ alike, explor-ing the methods of building safe and durable straw and earth houses. THE COB BUILDERS HANDBOOK 1997 by Becky Bee. Rammed earth has long been a popular choice for buildings where temperature fluctuations need to be kept to a minimum, such as the wineries of Western Australia. Noise Reduction The thickness and density of the walls mean that noise transmission is very much reduced. This is particularly useful if you want to keep out the noise of traffic or in party walls between townhouses.
The muting of external noise provides a quieter, more sheltered ambience, particularly evident in bad weather.Rammed earth internal walls are also extremely useful in providing sound insulation between areas with different needs — for instance between living and sleeping areas, or between a public or family room and a study area. CSIRO tests quoted in Bulletin 5 Earth-Wall Construction indicate a sound transmission rating of more than 50 decibels for a rammed earth wall of 250mm. Thicker walls, such as our standard load bearing walls of 300mm, provide even better sound insulation. Strong and Durable As CSIRO research (and centuries of years of use worldwide) has proved, rammed earth is extremely durable and weather resistant. We have almost 30 years of hands-on experience working with rammed earth.This, together with modern technologies, backed up with scientific testing and a strong attention to quality control, ensure maximum strength and durability for every project. Low Maintenance Rammed earth walls are extremely low maintenance. Once they are built and sealed, they shouldn’t need any further attention for at least 10-20 years.
At that point exposed walls may benefit from a second coat of sealer, which is an easy process.Rammed earth walls are features that stand alone and don’t need finishing with plasterboard or render, inside or outside. There is no need to ever again spend time and money painting.
However, if you do want a different finish, rammed earth walls can be treated in the same way as other masonry walls. You can cover them by applying plaster or render, or paint directly onto the surface. Fire Proof Earth doesn’t burn. This is an ideal material for bush settings and leafy suburbs. CSIRO tests (as outlined in Bulletin 5: Earth-Wall Construction, Fourth Edition) showed that a 250mm earth block wall achieved a 4 hour fire resistance rating.A 150mm earth block wall achieved a rating of 3 hrs 41 minutes. Our walls are stronger, being 300mm thick and of monolithic rather than block construction (so they have no vulnerable mortar joints).
Load Bearing Rammed earth walls at 300mm thick are load bearing, so you are unlikely to need other structural framing for your home, reducing fire and pest susceptibility. Rammed earth also provides substantial bracing to buildings — usually well in excess of the legal requirements achieved by most timber framed homes.Versatile Architects are using rammed earth in commercial and domestic buildings of many styles and for many functions. Variations in texture, colour and finish are possible, and elements such as artwork, reliefs, patterns, circular windows, alcoves and feature stones can be incorporated.
