What is the thermal mass?
Dwelling containing Bison concrete products are characterised by their inherent ability to soak up and release heat at different times of the day. During the summer, this means that heat is absorbed on hot days helping to stabilise the internal temperature and prevent overheating. The cool night air can then be used to ventilate the building and purge the accumulated heat from the building fabric. For more information, refer to the concrete centre: http://www.concretecentre.com
