LIP Reviewed by LIP on . Reflective material - Mylar, Visqueen, Foylon Mylar This material reflects 95% of the light that hits it. Great to use on walls to optimize light reflectivity. Visqueen Plastic Black/White Visqueen is a plastic that's black on one side and white on the other. It's 85% reflective and 100% opaque, which makes it a great option for use as reflective material or to use to block out light. Visqueen can also serve as plastic lining whereever it's needed. Very durable and washable, Visqueen comes 10 ft. wide Foylon Make your light more Rating: 5
