The polyethylene is clear and is protected with a strong ultraviolet inhibitor. The formulation of the plastic is designed for maximum light penetration and for durability in a greenhouse environment.  There are several advantages to using Ken-Bar tubing: Guarantee. Each tube is guaranteed to support the cubic feet/minute output of the fan. If there is a problem, the tubing will be replaced immediately. The 4-mil tubing is guaranteed for 1 year. Custom Punching. Ken-Bar provides proper diameter holes and spacing that conform to fan manufacturer’s specifications. A properly designed tube will make full use of the fan’s output by distributing air evenly down the length of the greenhouse. If we know the length of the house and the diameter of the fan, we can custom design the tube. Punch position can be varied as shown below to provide the best possible air flow for each situation. We will ship the Normal 8/4 unless you call to custom order. Installation Tips  We recommend that tubing be hung from a cable using tube hangers. These hangers do not penetrate the plastic. They consist of a loop of white plastic and a snap ring. The tube loop extends around the outside of the tube and is clipped to the cable using a snap ring. The hangers should be spaced 7 feet apart. Suggested uses for convection tubing: For ventilation when cooling greenhouses. For uniform dispersion of heat from a forced hot-air furnace. For improved mixing of air in greenhouses. For the introduction of dry air into greenhouses. To provide gentle streams of ventilation air instead of harsh blasts of air. To heat selected areas of a greenhouse when the whole house does not need heat.
