When it comes to transparent horticultural glass for greenhouse roofs and walls, there are several types available, each with its own unique characteristics and benefits. Here are some of the common types for greenhouse construction:
1. Float Glass: Float glass is the most basic and widely used type of horticultural glass. It is manufactured by floating molten glass on a bed of molten tin, resulting in a smooth and flat surface. Float glass offers good light transmission and clarity, making it suitable for greenhouse roofs and walls. However, it is not as durable as other types of glass and may require more frequent replacements.
2. Toughened Glass: Toughened glass, also known as tempered glass, undergoes a special heat treatment process to increase its strength and durability. It is several times stronger than regular glass and resistant to impacts, making it less likely to break. In the event of breakage, toughened glass shatters into small, safe fragments, reducing the risk of injury. Toughened glass is an excellent choice for greenhouse walls and roofs where safety and durability are paramount.
3. Diffused Glass: Diffused glass is specially designed to scatter and evenly distribute sunlight throughout the greenhouse. It helps reduce direct sunlight and prevents hot spots, creating more uniform lighting conditions for plants. Diffused glass improves light penetration into the canopy, reducing the need for supplemental lighting and promoting more balanced plant growth. This type of glass is often preferred for greenhouse roofs, where light distribution plays a crucial role in crop development.
4. UV-Blocking Glass: UV-blocking glass is treated to filter out a significant portion of ultraviolet (UV) radiation while allowing visible light to pass through. This type of glass protects plants from harmful UV rays, which can cause sunburn and other damage. UV-blocking glass is particularly beneficial in regions with intense sunlight or when cultivating light-sensitive crops.

In vegetable production, a rule of thumb states that 1% more sunlight equals 1% more potential yield. The greenhouse covering therefore should allow the sunlight to enter the greenhouse as much as possible for maximum potential photosynthesis. Just like every constructive element in the greenhouse, glass is evaluated carefully for its light transmission and its return on investment, if not more.
