This twinwall polycarbonate sheet is specifically designed for black or white greenhouse operations that want to hide all external light. It is most popular in the medicinal growing industry across the United States.
One side is opaque black and the opposite side is opaque white. The black side blocks 100% of exterior light from entering the constructed enclosure, regardless of which wall is outwardly facing. Typically, the white side is used as the exterior wall and the black side is used as the interior wall, however the panel comes with UV protection on both sides so that they are interchangeable for individual preference.
This sheet is available for special order only. Please call or email us

Sizes are available in 47.25", 48", 71.25", 72", and 82.67" widths and lengths up to 48'.
