With the development of agricultural technology to this day, let’s discuss which types of glass are most suitable for glass greenhouses today. First of all, we know that glass greenhouses are the most advanced type of greenhouses currently. Not only do they have high land utilization rates, but the ecological environment inside the greenhouses is easy to control. The fruits and vegetables grown are green, natural, and free of pests and diseases.

As the main covering material of greenhouse, what types of glass can be chosen:

The first is high-transmittance greenhouse side wall glass. Glass greenhouse side wall glass is mainly divided into two types, ordinary float glass, tempered glass, and ultra-white float glass.

The main functions of the side wall glass are thermal insulation and safety performance. It is generally 5MM thick and has double-layer hollow treatment, 5+6A+5 or 5+12A+5 treatment. Generally, the light transmittance of side wall glass is about 80%.

In order to ensure sufficient light inside the greenhouse, some greenhouses use ultra-white float glass so that crops close to the side walls of the greenhouse can also receive sufficient light.

The other is the top of the greenhouse. The glass on the top of the greenhouse is the main source of light, and there is another consideration.

At present, the glass choices for the top of the greenhouse are divided into three categories: ultra-white tempered glass, ultra-white scattering glass, and ultra-white anti-reflective glass.

The reason why non-tempered glass is not mentioned here is that the height of the greenhouse is generally designed to be 5-7 meters. After the non-tempered glass is broken, it will appear blocky and large. If it falls from a height of 7 meters, it will easily damage crops and staff. (Among the projects the company has learned about, there are also many projects that have been stopped due to injuries to personnel using non-tempered glass.) Among the glass on the top of the greenhouse, ultra-white tempered anti-reflective glass has a light transmittance of 97.5%, which is currently the most energy-saving greenhouse glass. It has the highest light transmittance and is also the most widely used glass.

Compared with greenhouses covered with other types of glass, greenhouses covered with anti-reflective glass can increase yields by more than 36%.

Secondly, the glass that can be selected for the top of the greenhouse is ultra-white scattering glass. The light transmittance of ultra-white scattering glass is 91.5%, which is a conventional specification for glass greenhouse glass. Ultra-white tempered scattering glass has high scattering characteristics. Depending on the degree of scattering, every area of the greenhouse can receive sufficient light.

In a greenhouse covered with diffused glass, the side walls of the greenhouse can be avoided, and the crops in the corners can also receive sufficient light. In a 7-meter-high greenhouse, crops can grow to a height of 5 meters. Highly scattering glass can scatter light to the roots of crops. The roots of crops that receive sufficient light can prevent the growth of gray mold and prevent the growth of root diseases.

The last is ultra-white tempered glass. The light transmittance of this type of glass is 90%. Currently, few customers use non-scattering tempered glass. Ultra-white float tempered glass has no yield-increasing effect for greenhouse cultivation.

Finally, there are the following recommendations for greenhouse top glass selection:

Thickness: 4mm is better than 5mm

Type: [Ultra white anti-reflection tempered glass] is better than [ultra white scattering tempered glass] is better than [ultra white tempered glass]
