Abstract:

Used as “ Nano Insulation Materials (NIM)”[ NIM - A basically homogeneous material with a closed or open small nano pore structure with an overall thermal conductivity of less than 4 mW/(mK) in the pristine condition].by using these the insulation property is much improved.

Mixing NIM’s with concrete walls reduce the width of the walls and also enhance the insulation property. By the older one we have “Mineral Wool or Polystyrene 36 mW/(mK)” and by the “NIM’s 3.6 mW/(mK)”. A vast reduction – factor 10 – of the thermal insulation layer and

thereby the total building envelope thickness. Several possibilities of applying nano

technology and nano insulation materials (NIM) in order to improve the thermal performance of the future concrete buildings have been presented.
