Glass For Greenhouse

When it comes to greenhouse production, every detail matters. A key rule in greenhouse cultivation states that 1% more light equals 1% more crop production. That’s why choosing the right greenhouse construction glass is essential. At DutchGreenhouses®, we provide high-quality solutions tailored to maximize sunlight entry and optimize plant growth in both commercial glass greenhouses and smaller structures.

Types of greenhouse glass

Two primary types of glass panels for greenhouses dominate the market:

Horticultural Float Glass (Non-Tempered)
Tempered Glass for Greenhouses

Each has unique benefits depending on its application in a glass greenhouse project.

Non-Tempered Float Glass for Greenhouses

Float glass, also known as annealed glass, is the most common material for greenhouse window glass and side panels. Its flexibility allows for easy customization and cutting, making it suitable for detailed glazing work.

However, non-tempered greenhouse glass is not recommended for roofs. When broken, it shatters into sharp, dangerous fragments, creating unnecessary risks during installation and operation. Instead, DutchGreenhouses® uses it sparingly in lower-risk areas such as side walls. This type of greenhouse glass small is also a cost-effective option for growers who prioritize budget-friendly solutions.

Diffuse greenhouse glass

Tempered glass greenhouse panels are the preferred choice for modern structures. This type of greenhouse replacement glass is treated through a heat tempering process, making it:

Four to five times stronger than float glass.
Safer, as it breaks into small, non-sharp fragments when shattered.
Highly durable for long-term use in both roofs and walls.

Additionally, tempered glass for greenhouses offers advanced treatment options, such as:

AR Coatings: Permanent anti-reflection coatings increase sunlight transmission, reducing reflection.
Diffuse Glass: Scatters light evenly to minimize shadows and hotspots, boosting photosynthesis and plant growth.

Whether you’re constructing a commercial glass greenhouse or looking for greenhouse replacement glass, tempered options provide the durability and safety you need.

Low-Iron Greenhouse Glass: Maximum Light Transmission

For growers seeking the ultimate in light transparency, low-iron glass is the answer. This type of glass sheets for greenhouses is specially designed to allow more natural light to pass through. When combined with AR coatings, low-iron tempered glass significantly boosts light transmission, making it ideal for glass for greenhouse roofs and walls.

FAQ

Which types of glass are used in greenhouses?

Greenhouse glass can be categorized into two glass types: non-tempered glass and tempered glass. These can be low-iron for more light translucency, or just as regular float glass. For safety reasons, non-tempered glass can only be used in side-walls. Tempered glass gives options for diffuse glass and AR-coating possibilities, to compensate for the loss of light due to diffusion.

What is the advantage of diffuse glass in Dutch greenhouses?

The special property of diffuse glass to scatter light, ensures a more uniform distribution of sunlight across the plants, reducing shadows and hotspots. More even light distribution allows for better photosynthesis, which can enhance plant growth and productivity. Additionally, diffuse glass can help in reducing stress on plants caused by direct sunlight, making it particularly useful in regions or seasons with high light intensity. Overall, the use of diffuse glass contributes to higher yields and better quality crops.

What are the disadvantages of diffuse glass in greenhouses?

Although diffuse glass has many benefits, the disadvantages also need to be considered:

- Costs (tempered diffuse glass is more expensive than regular tempered glass)

- Loss of light (AR coatings can compensate the loss of light transmission, but add onto the costs of the diffuse glass)

- Loss of flexibility (tempered diffuse glass will limit the flexibility in switching crops, reselling and anticipation between seasons)

What is Haze in greenhouse glass?

The Haze-factor is the level of light diffusion, quantified into an index number. The Haze-factor equals the percentage of light that is scattered above an angle of 2,5 degrees.
