This record may be used to define the structure of constructions (walls).
Parameter mats should be used to define the type
and thickness of each material layers.
Parameter incLastLay may be used to define the
intended inclination angle of the last material layer. This is to
check if you correctly connect models that used this construction
since otherwise the natural convection correlations may be computed
for instance assuming a floor orientation instead of a ceiling
orientation.
Edge effects are neglected. A simple correlation for unventilated cavities is used when modeling an air layer.
nLay(min=1)=size(mats,1) and nGain =
size(locGain,1).
