R-VALUE OF 
INSULATIONS
The effectiveness of an insulating material in
resisting conductive heat flow is gauged by its
thermal resistance, denoted as the R-value. A
higher R-value indicates superior insulation. This
value is influenced by insulation type, thickness,
and
density, and can also be affected by factors such as
temperature, aging, and moisture. To determine
the R-value of a multi-layered installation, simply
sum the R-values of each individual layer.
RADIANT BARRIERS
Radiant barriers, comprised of highly reflective materials, deflect
radiant heat rather than absorbing it, thereby diminishing cooling
loads. Consequently, radiant barriers do not possess an intrinsic 
R-value.
