Knitted from transparent UV stabilised polyethylene thread, Tunnet is permeable to air and water, preventing overheating, excessive humidity and condensation - creating ideal growing conditions. Tunnet also gives extra protection from crop damage due to frost, hail, highwinds, birds and other pests.
Tunnet weighs 80grams/sqm, has a break strength of 450kg/m, has a covering of 98%, shading of 19% and typically gives frost protection of around 2-4 degrees.
Tunnet has been used with great success over a wide range of structures, from small individual shelters to protect shrubs or trees (avocados), cloches for vegetable growing, low lying hydroponics and watercress systems to large canopies covering vegetables, flowers and tropical fruit trees.
Tunnet cover can be used as a thermal blanket installed inside a glass or plastic house to defuse light, slow down heat loss and reduce condensation.
It does not loose its strength when wet or frostly and on smaller structures (such as avocado shelters) it strong enough that it can be stapled in place.
TUNNET is available in rolls of: 2m x 100m, 4m x 100m, 6m x 50m & 8m x 50m.
TUNNET is also available in cut lengths 2m, 3m and 4m wide.
