Introducing Straw-Wall Technology: Eco-Friendly Prefab Homes with Innovative Wall Components.
When considering prefab homes or modular homes, the final product depends on the ingredients and the preparation method. The same applies to BIOBUILDS houses, where wall components represent one of the innovations at the core of the entire concept. These prefab houses not only serve as minimalistic small houses or tiny homes but are also off the grid ready, showcasing eco-friendly green building practices.
8 Years of Continuous Innovation in Straw Prefab and Modular Homes
To reach today's formula for these energy-efficient eco-houses, many materials were tested, and various construction solutions were considered. In the end, the recipe we mentioned earlier was developed, making our prefab homes a perfect example of Passivhaus or passive house standards.
Components of BIOBUILDS Straw Walls Passive Houses
Silicate decorative plaster
Agepan THD wood fiber thermal insulation
Agepan DWD protect rigid wood panel
Straw filler
Agepan OSB
Proclima Intello vapor barrier
Active Air gypsum board
Washable paint
These modular building components are designed with sustainability in mind. Besides the quality of each element that forms the final panel, the arrangement of these elements is crucial, directly influencing the panel's efficiency and resistance to moisture.
Features of BIOBUILDS Walls in Green Prefab Homes
Straw bales in these tiny homes are compressed at a constant density of 105 kg/m3, adding rigidity to the construction system while cladding on both sides ensures the bracing of the assembly. The entire structure functions like a box, exhibiting elastic behavior under lateral loads caused by wind or seismic movements. Compressing at such density eliminates oxygen, creating a fire-resistant, class A1 environment.
During production, windows and doors are installed, interior gypsum board is added, and the first layer of exterior plaster is applied. Walls are then sent to the construction site, ready for assembly, requiring only minor finishing work.
One square meter of wall blocks approximately 90 kg of CO2 through the use of straw in the structure. This amount is equivalent to the emissions of a medium-class diesel car driving 70,000 km or a Boeing 747-400 flying for one hour. As a result, a 12-meter long and 3-meter high wall removes 3.2 tons of CO2 from the atmosphere.
The intelligent membrane we use ensures both the air tightness of the system and the optimal diffusion of water vapor (excessive humidity) from the interior to the exterior, making the entire wall permeable and allowing the house to breathe. Consequently, mold growth is impossible.
These energy-efficient prefab homes are perfect for those looking for a sustainable and eco-friendly option in the world of modular homes and tiny homes.
