Colored roofing membrane with improved solar reflectance
A multilayer roofing material includes a first layer, a second layer, a third layer, and a fourth layer. The first layer is a topmost layer and a color layer. The first layer comprises a UV stabilizer. The second layer comprises TPO. The second layer is a white layer. The third layer comprises a scrim. The third layer contacts the second layer and the second layer is between the first layer and third layer. The fourth layer comprises TPO. The fourth layer is a core layer. The fourth layer contacts the third layer.
