Mirror-like metalized Mylar surface reflects more light to plants, and more light = increased growth & higher yields! Line walls, ceilings, and even floors to ensure optimum lumen efficiency. Multipurpose Mylar on white poly combo film offers a bright white alternative surface, and opaque (non-see-through) property makes it great for covering windows as well. Heavier 2-mil thickness for durability. Roll measures 4 ft. x 25 ft. Please Note: The metalized silver side does not produce a clear mirror image, and thus is not recommended for visual applications in which this quality is desired.

Difference is felt right after installation, high light reflectivity and heat containment.

Exactly as the description implies, it is a large roll of reflective mylar. Easy to cut and should be useful for whatever you intend to do with it.
