Tufflite IV UV Protected Greenhouse Film | 6 Mil Tri-Layer – 40ft x 100ft

What Goes Into Tufflite IV Greenhouse Film This is the four year grade rather than the seasonal one, and the difference is in the resin. Berry builds it as a tri-layer polyethylene at six mil, from a high strength proprietary polymer blend. The UV stabilisation is carried through the material rather than coated onto the surface. Light transmission runs above ninety-one percent, which matters more on a PAR basis than a brightness one. Three additives do the rest of the work. An anti-drip additive changes how moisture behaves on the underside. An anti-dust additive slows the film gathering the grime that quietly steals light over a season. Light dispersion additives scatter the beam, which softens the hard bright and dark patches a clear film throws onto a canopy. That stabilisation holds the light transmission figure steady across four years rather than letting it fall away in the second. Clarity is retained without the discoloration and cracking that ends lesser film early. Anti Condensation, Warranty Terms and What Kills Film Early Two things about this product are worth knowing before it goes up. The first is the warranty condition. The four year term applies where the film is run as a double layer with air inflated between the sheets. A single layer skin is a legitimate way to build. It is not the configuration the warranty was written against, so check before planning around it. The second is chemical contact. Polyethylene is degraded by the gases coming off PVC. Film resting against PVC pipe or fittings fails at the contact point long before the rest of the sheet does. Pad or sleeve any crossing. The anti-drip additive makes water sheet down the inside rather than bead and fall. That keeps drips off the canopy and reduces the disease pressure arriving with them. Rolls here run twenty, twenty-four, thirty-two, forty and forty-eight feet wide, all at one hundred feet long. Each arrives centre folded for easier handling.
