Laminated Curved Glass for Aquariums and Zoos: How Does it Stand Up to Water and Pressure?


Laminated curved glass is a remarkable material that has been widely used in the construction of aquariums and zoos. It offers a unique combination of strength, durability, and aesthetics, making it an ideal choice for these specialized applications. In this article, we will delve into the properties of laminated curved glass and explore how it stands up to the challenges posed by water and pressure.

The Advantages of Laminated Curved Glass

Laminated curved glass offers several advantages over traditional flat glass when it comes to creating aquariums and enclosures for animals. Firstly, its curved shape allows for a wider field of view, providing visitors with an immersive experience. Additionally, the smooth contours of the glass create an aesthetically pleasing look, enhancing the overall appeal of the exhibit. Moreover, laminated glass is incredibly strong and resistant to impact, making it a safe choice for structures that need to withstand the weight of large volumes of water and the pressure exerted by it.

Properties of Laminated Curved Glass

To understand how laminated curved glass can withstand water and pressure, it is crucial to explore its unique properties. Laminated glass consists of multiple layers of glass sandwiched together with an interlayer typically made of polyvinyl butyral (PVB) or ethylene-vinyl acetate (EVA). This combination gives laminated glass its strength, as the interlayer acts as a bonding agent, firmly holding the glass together even when it breaks.

Water Resistance

Water resistance is of utmost importance when designing aquariums and zoo enclosures. Laminated curved glass effectively prevents water penetration, ensuring that aquatic habitats are contained securely. The interlayer used in laminated glass acts as a barrier, preventing any leakage or seepage of water. The tight bond formed between the layers ensures that no water particles can infiltrate the enclosure, maintaining a safe and controlled environment for the animals.

Pressure Endurance

Aquariums and zoo enclosures must withstand the immense pressure exerted by the weight of the water they contain. Laminated curved glass is specially designed to handle such pressure. The multiple layers of glass, combined with the interlayer, distribute the load more evenly, minimizing the chances of breakage or structural failure. This unique construction allows laminated curved glass to cope with the long-term stress generated by the water, ensuring the safety of both the aquatic inhabitants and the visitors.

Impact Resistance

Another critical factor to consider is the impact resistance of laminated curved glass. In busy public areas such as zoos and aquariums, accidental collisions or enthusiastic touches from visitors can occur. Laminated glass offers remarkable impact resistance, as it is designed to remain intact even when shattered. The interlayer holds the broken glass in place, preventing it from falling apart and causing harm. This feature not only ensures the safety of the visitors but also reduces the risk of injury to the animals within the enclosures.

Temperature and UV Stability

Maintaining constant and suitable temperatures within aquariums and zoo enclosures is vital for the wellbeing of the aquatic and animal species. Laminated curved glass exhibits excellent stability against temperature variations, protecting the inhabitants from sudden changes in climate. Moreover, it provides excellent UV filtration, shielding the animals from harmful ultraviolet radiation and reducing the risk of sunburn or heat stress.

Aesthetic Appeal

Apart from its functionality, the aesthetic appeal of laminated curved glass plays a significant role in creating visually stunning exhibits. The curved shape of the glass offers uninterrupted panoramic views, allowing visitors to admire the beauty of aquatic life or observe animals in a more natural habitat. The absence of horizontal mullions or joints, commonly found in traditional flat glass installations, enhances the viewing experience and adds an element of elegance to the overall design.


Laminated curved glass demonstrates exceptional resilience when faced with the challenges posed by water and pressure. Its unique properties, including water resistance, pressure endurance, impact resistance, temperature stability, and UV filtration, make it the ideal choice for aquariums and zoo enclosures. Not only does it provide a safe and secure environment for the animals, but it also offers an immersive experience to visitors. As technology continues to evolve, laminated curved glass is expected to play an increasingly significant role in the design and construction of modern zoological and aquatic exhibits.
