Curved glass has become a popular choice in the construction of modern greenhouses, offering unique aesthetics, energy efficiency, and superior functionality.
This article will explore the benefits and specifications of using double curved glass in greenhouse construction, as well as the advantages of using double glazed curved glass in various environments.

What is Double Glazed Curved Glass and Its Applications in Greenhouses?
Double curved glass is a unique type of glass that features two curved surfaces, making it ideal for applications that require both strength and a high degree of light transmission. In curved glass greenhouses, it plays a crucial role in ensuring structural integrity and maximizing sunlight penetration for plants.
What Is 5mm+12A+5mm Double Glazed Curved Glass?
The term “5mm+12A+5mm” refers to the thickness and composition of the double-glazed curved glass. The first and third layers are 5mm thick tempered glass, while the middle layer consists of a 12mm thick air cavity, which provides excellent thermal insulation. This configuration enhances energy efficiency by reducing heat loss and improving indoor climate control in greenhouses.

How to Produce 5mm+12A+5mm Double Glazed Curved Glass?
To produce 5mm+12A+5mm double glazed curved glass, several key steps are involved to ensure both the curvature and insulation properties are met.
- Glass Cutting and Shaping: Start by cutting two 5mm thick tempered glass sheets to the required dimensions. These glass sheets are heated and bent into the desired curvature using a hot bending process, which makes them malleable for shaping.
- Tempering: The curved glass sheets are tempered by heating and rapidly cooling them to increase strength and durability.
- Spacer Preparation: A 12mm thick spacer, typically made from aluminum or stainless steel, is prepared to separate the two glass layers. This spacer is coated with a sealant to prevent moisture from entering the cavity.
- Assembly: The spacer is placed between the two glass sheets, and butyl sealant is applied around the edges to create an airtight bond.
- Coating (Optional): If needed, a Low-E coating is applied to improve thermal insulation by reflecting heat and minimizing energy loss.
- Edge Sealing and Curing: The perimeter of the glass is sealed with silicone or polyurethane, and the unit is allowed to cure to ensure proper bonding and insulation.
- Inspected: finally, the finished glass is inspected, and packed.
Benefits:
Double glazed glass offers several benefits, making it a popular choice for both residential and commercial applications.
Improved Insulation
Double glazing creates an insulating barrier between the two panes of glass, helping to keep heat inside during the winter and outside during the summer. This significantly improves energy efficiency.
Noise Reduction
The space between the two layers of glass acts as a sound barrier, reducing the amount of external noise that enters the building. This is particularly beneficial in noisy urban areas.
Condensation Control
Double glazing helps to reduce condensation on windows of a curved glass greenhouse, as the inner glass stays warmer than single-pane windows, preventing moisture buildup.
Enhanced Security
Double-glazed windows are harder to break than single-glazed windows due to the additional layer of glass, adding an extra level of security to your curved glass greenhouse.
UV Protection
Many double-glazed curved glass greenhouse windows come with coatings that block harmful UV rays, helping to protect your furniture, flooring, and other interior elements from fading.
Lower Energy Bills
The improved insulation provided by double glazing can reduce the need for heating and cooling, leading to lower energy consumption and, in turn, lower utility bills.
