Heat Convection            

  In addition to the heat transfer by colliding molecules, the heat is also transferred into another medium by the movement of the air. The natural convection takes place in a simple manner when this movement results from the density difference caused by the heated air which rises and replaces the volume of the colder air. '' We can briefly define the heat convection which mostly takes place in liquid or gaseous materials, as the difference in the position of the warmed masses of particules.''  
 
  When the circulating pattern of air flow is prevented, the air layer becomes a good heat insulater. In fact, the most of the heat insulating materials function by making use of this basic property. The air flow circulating in the exterior layers of buildings can be minimized by allowing appropriate combinations of different layers of the outer layers of buildings

Radiation  

  The radiant heat can not be transferred upon gases. The heat transfer by radiation emitted from the sun is the sole means of energy necessary for the life on our planet. The sun light is also viewed as the electromagnetic waves ranging in specific lengths which is independent of the matter a emission medium

   When two objects are separated by a space which is itself a radiation permeable medium (gas), the hotter object radiates energy whereas the cooler object absorbs this electromagnetic radiation at the same time. The energy incident on the cooler object is absorbed to some degree and the rest is reflected back. These are actually everyday incidents at the buildings anywhere in the world.

' The heat transfer by radiation can be taken under control by filling the exterior wall spacings with insulating material in such a way that neither of the corresponding surfaces see each other unshielded.''

  Thermo - SİM, plaster-like applicable heat insulation material makes it more comfortable to live in buildings and reduces air pollution by preventing heat transfer in-between the environments. Being not inflammable, selective permeability enabling the breathing of surfaces, and water insulation are among other outstanding  material properties of the product Thermo - SİM.
