This utility model discloses a PVC co-extruded louver profile. The lower end of the main body has mounting brackets on both sides. Each mounting bracket has an adjustment mechanism inside and a movable groove inside. A strip plate slides along the inner wall of the movable groove, and a transmission rack is fixedly connected to the side wall of the strip plate. During use, this louver profile utilizes an anti-UV layer. This layer absorbs or reflects ultraviolet rays, forming a light shield by physically blocking and reflecting ultraviolet light, thus reducing direct contact between ultraviolet rays and the substrate and improving the lifespan of the louver. The heat-reflective layer reflects solar heat and reduces the profile temperature, solving the problems of high energy consumption and easy deformation of traditional louvers in high-temperature environments. The anti-UV layer prevents material degradation due to light exposure, while the heat-reflective layer reduces heat transfer, achieving dual energy saving through sun protection and heat insulation.
