In many areas of the world there is growing requirement for films that reduce excessive heat during the day time and help to maintain a cooler environment in the greenhouse. Particularly in the "tropics", in areas with strong sunlight and hot weather as well as in nurseries, or in cases of shade-loving plants, “cooling films” are gradually becoming a necessity.

Hitec's product range offers special film types which reflect and /or absorb Near Infra Red (NIR) radiation, the part of the solar spectrum carrying most of the heat entering a greenhouse. NIR radiation is not essential to plant growth and by preventing it from entering the greenhouse, “cooling films” achieve significant reduction of heat inside the greenhouse during the day time. Usage of such films has demonstrated that the higher the ambient temperatures of the area are, the larger is the heat reduction achieved
