The structural system, Platform Frame and light wooden structure allows an optimal use of the materials, being widely used in highly technological developed countries such as The United States, Canada, Northern Europe and Japan. Due to its high performance, wood is an excellent material, being at the same time light, resistant and long lasting. The high level of industrialization today allows the modulation of the structure, thus time and material are saved. Moreover we must not forget that wood is a sustainable resource with a negative carbon footprint if it is correctly managed. At BASS, the Forest Stewardship Council (FSC) certifies all of the wooden elements.
2. Structural resistance.
Woods structural capacity is not affected a bit by its light nature and it is the material that bears the best weight-to-resistance ratio, beating even concrete and steel.
BASS SYSTEM offers the best solution in case of seismic activity; continuous framing, low weight and flexible materials guarantees structure integrity and prevents possible damage resulting from landslides that can occur using traditional systems .
Reassurance in case of a fire.
The structured wood is protected by other elements of the system offering an excellent performance; the wood is never accidentally exposed in the event of a fire. Added to that, we prevent the so-called chimney effect in the insulating chambers of the facade. On the other hand, strict compliance of the Technical Building Code guarantees that the BASS structures have the same resistance in case of a fire as is required for steel and concrete structures. We should also take into account that the use of biocompatible materials such as cork and wooden fibre confer an advantage in case of a fire as it avoids the spreading of flames. Besides in its combustion only CO and water vapour is produced, this is much less damaging than the gas released at high temperatures by the more common industrial insulations such as polystyrene or polyurethanes that in some cases may even be more dangerous than the flames.
3. Mining and transformation impact.
As compared to the traditional structural materials, such as steel, concrete and ceramic, which release CO2 emissions in their manufacturing and recycling, the cutting down and sawn timber does not involve an impact upon the environment. At the moment of combustion and decomposition, the emission of CO2 to the atmosphere will be identical to the one used in the process of photosynthesis. The process of wood consumes less energy than the rest of raw materials. The production of pieces of wood, contrary to the conventional construction materials, requires a lower amount of water and therefore causes less impact in the quality of the tributary wastewaters that are generated. Timber waste generates residue, which is a natural material, therefore totally biodegradable, recyclable and reusable as biomass.
The structural wood is completely protected from the outdoors by the other elements of the building envelope. In this way, the conditions of humidity and temperature are kept constant, which makes the lifespan of the building superior to 500 years; as many buildings of our historical heritage show.
