The present invention relates to a heat-reflection thermal insulating film, which can be mounted windly or unfoldly on the beam of the framework on the greenhouse. The insulating film comprises two outer layers and at least one inner layer, which are connected by bands. Furthermore, each of the outer films is coated by an infrared-reflection layer. So the invention has advantages of having good thermal insulating properties and reasonable construction, being convenient in wind and unfold operation, saving time and labour, extending the illumination time, having clean and tidy exterior. |
