TPEC coatings have solar reflectivity ranging from 60% to 75%, better than conventional trailer roofing materials, with reflectivity of 5% to 25%, and metals, with low emissivity ranging between 20% to 60% depending on surface finish and condition.
Conventional roof surfaces with low reflectivity and high emissivity heat to 160° to 190° F at midday in summer. Metal or aluminum coated roofs with high reflectivity and low emissivity warm to 140° to 170° F. By comparison, TPEC roofs only reach 100° to 120° F (mostly less) in the summer sun.
A TPEC surface reflects the sun's ultraviolet rays and slows down roof aging. It prevents corrosion; fights against growth of mold, mildew, fungus, and algae; and has good hail resistance.
Being a 100% acrylic elastomeric, TPEC reduces expansion and contraction of a reefer roof, which helps to keep roof seams from leaking. TPEC doesn't experience large daily temperature fluctuations so it undergoes less thermal fatigue. Lower roof and wall temperatures also reduce the rate of any chemical breakdown.
