IR Reflective Technology - Chromaflo

A surface stays cool by having high solar reflectance and thermal emittance. High solar reflectance in turn lowers solar heat gain while high thermal emittance enhances thermal radiative cooling. The more solar energy an object absorbs the greater the heat build-up. Conversely the higher the solar reflectance the cooler an object will stay.【Get Price】
