What is polythene ducting
Polythene ducting is the most economic and efficient method of distributing warm and cold air. A typical polythene ducting system consists of one or more inflatable polythene ducts suspended overhead from steel wires. Rows of small holes in the sides of the ducts produce jets of air, with enough throw to create continuous gentle air movement throughout the building.
Polythene ducting is compatible with most fans, heaters, air conditioners, air handling units, etc. Its adaptability and very low cost make it suitable for use as heating, cooling or ventilation ducting in a wide range of buildings and industries.
The Activair polythene ducting system
Inflatable polythene ducting has been used in commercial glasshouses since the early 1950s. In 1956 Activair patented a system that greatly improved its performance.
Before this polythene ducting was manufactured with holes equally spaced along its
length. This led to poor air distribution and temperature gradients. Unfortunately, many suppliers still use
this method today
