Energy Saving Verosol SilverScreen Roller Shades are an innovative breakthrough in solar and heat control. Verosol SilverScreen enhanced transparent woven material has a highly reflective, ultra fine layer of aluminum vacuum bonded to the exterior facing side of vinyl coated woven fiberglass. The fabric is then given a special finish that protects the bond making it ideally suited for roller shades. The aluminum layer reflects solar heat for cooler temperatures during the summer. All transparent shades provide daytime privacy only.
