The thicker the greenhouse film, the better the insulation performance?

Time：2023-10-10

In the construction of greenhouses, the choice of greenhouse film is very important. Not only to be durable, but also to withstand the impact of general climate disasters on the cultivation of crops inside the greenhouse. Many customers who are first exposed to greenhouse production think that the thicker the plastic greenhouse film, the better the insulation effect. Is this really the case?

In fact, the thicker the greenhouse film, the better the insulation effect. This perception is wrong. First of all, I would like to talk about the principle of greenhouse film insulation: the greenhouse film divides the space in the shed into independent enclosed spaces to effectively store heat and effectively prevent internal and external heat exchange. So, where does the heat in the greenhouse film come from? Its heat mainly comes from the sunlight shining on the wall to produce infrared radiation and the reverse radiation of the earth.

If the plastic greenhouse film we choose is too thick, the ability of the sun to pass through the film body will be greatly reduced. This leads to poor temperature in the enclosed space. Therefore, the thicker the plastic film, the better the insulation effect is wrong. When buying greenhouse film, we recommend that most users buy according to their actual situation, and adjust measures to local conditions to promote the growth of plants and improve crop yield and quality.
