There are many types of greenhouses. Among the types of greenhouses that are still being researched and produced, the veined greenhouse is the first. Therefore, when choosing greenhouse glass, please remember the following points:

First of all, the transmittance is important, and the haze value is important

Transmittance: Those who are engaged in planting know that the higher the transmittance, the higher the yield of crops grown in the greenhouse. In essence, one sunshine, one harvest.

Therefore, the most basic transmittance of the glass panel used on the top of the greenhouse is 91.5%. If you want a higher transmittance, you can use double-sided coating, which can reach a transmittance of 97.5%.

97.5% transmittance is the best glass specification in the greenhouse industry.

Haze value: In some areas with too much light, such as countries near the equator, you need to consider how to solve the problem of too much light without changing the transmittance. Therefore, the haze of the glass comes into being accordingly.

Haze, we call it hemispherical transmittance. Starting from the first ray of light shining into the greenhouse, to the last ray of sunlight shining into the greenhouse.

The conclusion drawn from the average light intensity of the whole day is called haze.

The higher the haze, the lower the hemispherical transmittance will be, and vice versa.

Here are the points we should be careful of: Don't use ordinary white glass, glass without haze specifications

Don't use ordinary white glass: The transmittance of ordinary white glass is 88%-89%. For greenhouse planting, the plants get too little sunlight and the crops do not grow, so it is not suitable for use in greenhouses.

Glass without haze specifications: How to judge the haze of glass, we can shine a beam of light on it after getting the glass, and the laser pen works best.

Cast the light on the wall one meter away to see the size of the light spot, and then enlarge it year by year. On a greenhouse 5-8 meters high, how big is the light spot projected on the plant.

The energy of a beam of light is limited. If it is too scattered, the light will be weak. If the light is too weak, nothing can grow in the greenhouse.

The rollers used to make greenhouse glass are all customized. The pressed patterns are fine and regular, and the projected light is more uniform, which can better ensure the high hemispherical transmittance of the greenhouse.

Next, let's look at a set of detailed test data.

The hemispherical transmittance of the greenhouse glass pressed out by the roller with [30 haze] is the standard:

Let's look at another set of data, this time looking at [75 haze]

From the above data, it can be seen that the hemispherical transmittance of 30 haze and 75 haze glass is very different. The transmittance of low haze glass is higher than that of ordinary glass even at sunrise.

The above are the standards for selecting greenhouse glass. In fact, the requirements are summarized as follows:

1. The transmittance must be high and cannot be lower than 91.5%.

2. There must be a hemispherical transmittance standard and a haze parameter.

The diffuse glass and AR-coated diffuse glass produced by Yuhua have cooperated with many large commercial greenhouses in agriculture, horticulture, nurseries and experiments. We have cooperated with large greenhouse project companies such as Havecon, Van Der Hoeven, Kubo, etc. for many years. Yuhua greenhouse glass has a light transmittance of up to 99%, and haze 5/10/20/30/50/70/75 greenhouse diffuse glass is available!
