4. Reflective insulations
4.1 Reflective films
To increase the efficiency of insulation systems, low-emissivity (ε " 0.1) reflective films are sometimes used as surface coatings for walls or insulation.
At the wall-air interface, heat transfer by natural convection and radiation is expressed by the relationship :
