10ft 1 mil x 54" reflective mylar mirror sheeting, coated both sides
Mirrored on both sides, 1 mil thick x 54" wide. Rolled around a 3" carpet core, wrapped in plastic, then corrugated cardboard, and placed in a box. 1 Mil is approximately the thickness of tissue paper, which makes it ideal for applications where distortion is not a concern. It has been used rather successfully as a heat barrier such as on ceilings of attics as well as most situations where there is a large amount of area to cover to prevent heat or cold from being dissipated. It has also been used extensively for redirecting light for better plant growth.
