Solar Energy Reflected
Solar energy reflected is the fraction of incoming solar radiation that bounces off a window film back to the exterior, without entering the glass at all.
High reflection is the most efficient form of solar control — energy that never enters the glass doesn't need to be absorbed or re-radiated.
Multi-layer optical and advanced nano-ceramic films achieve high reflection of NIR while keeping visible-light reflection low. This is the spectral selectivity that makes top-tier clear-IR films possible.
Solar energy reflected appears in spec sheets as part of the total solar energy rejection calculation, alongside absorption and transmission.
