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 : $| \vec{q} | = | {\vec{q}}_{c v} | + | {\vec{q}}_{r} | = (h_{c v} + h_{r}) \cdot S \cdot (T_{1} - T_{A})$
