In the world of building greenhouses, glass is a top choice. It’s great because it lets lots of light through, lasts a long time, can handle the heat, stays clean, and stops dew from forming. These features make glass the go-to material for many greenhouse experts. This article explores the different types of glass used in glass greenhouses and their key features, helping you build a better commercial greenhouse.

What Type of Glass is Used for Greenhouses?

Greenhouse Side Wall Glass

The side walls of the greenhouse typically use standard 5+6+5mm insulated float glass. Since a lot of heat escapes through the greenhouse walls and leaks in winter (70-80% of total heat loss), enhancing the insulation and sealing of the structure is key. This approach effectively reduces heat loss and is cost-efficient.
Greenhouse Roof Glass

For the roof, we prefer 4mm tempered scattering glass with over 91.5% light transmittance. This glass, combined with special aluminum profiles and durable rubber seals, offers excellent sealing and looks great. Tempered glass boasts amazing strength and break resistance.
Greenhouses, usually 5-7 meters tall, are often used for vertical farming of fruits, vegetables, flowers, and medicinal plants. Safety is a top priority for such tall structures, especially the roof glass. Tempered glass is essential to prevent accidents during severe weather.
Another important factor is light scattering. Controlling temperature is vital for year-round farming and impacts operational costs. The 4mm tempered scattering glass, with up to 97.5% light transmittance, ensures enough light without the risk of underexposure. It softens sunlight, preventing leaf burn in plants, and can reduce indoor temperatures by about 5 degrees Celsius in summer.
We choose tempered scattering glass with varying haze values to suit different light and temperature conditions.

FREQUENTLY ASKED QUESTIONS

FAQ: How thick should the glass be for a greenhouse?: The right glass thickness for a greenhouse varies. It depends on where you’re located, the weather, what your greenhouse needs structurally, and your budget. The usual choices are 4mm and 5mm.
For example, 4mm tempered scattering glass is great for greenhouse roofs because it’s strong and lets plenty of light through. For the sides, 5+6+5mm insulated float glass works best, offering top-notch insulation.
FAQ: What is the most efficient greenhouse glass?: The best greenhouse glass has high light transmission, scatters light well and insulates effectively. Ultra-clear anti-reflective glass is a top pick because it lets through 97.5% of light, boosting light efficiency. Glass that scatters light evenly is also great. It reduces the stress of direct sunlight on plants and keeps leaf temperatures lower.
FAQ: Do greenhouses use normal glass?: Regular glass, like the kind in homes or stores, isn’t ideal for greenhouses. Greenhouse glass needs to let lots of light through, resist impact, last long, and have special scattering or reflective qualities. Even when a greenhouse uses normal float glass-like material, it’s usually treated (like being tempered or coated) to meet the unique light and weather demands of greenhouses.
