Why Acrylic panel for Infinity pool windows but not glass?

First, the impact resistance of acrylic is very strong—100 times that of glass and 16 times that of tempered glass—and the thickness of acrylic sheet can be over 800mm, and the safety factor increases exponentially. The Infinity  pool needs to withstand the dynamic pressure and wind pressure caused by water pressure, people flow, and waves. This pressure is dynamic and uncontrollable. As a flexible polymer material, acrylic has excellent strength, toughness, and resistance to bending and fracture. It is very suitable for this complex, stressful environment. Tempered glass is relatively brittle and faces a complex pressure environment. Coupled with the influence of a series of outdoor environments such as sunshine, climate, and temperature differences, the probability of nickel sulfide crystal expansion increases, which will increase the risk of self-explosion.

Second, the light transmittance of acrylic is very good; the light transmittance of general glass is 82%–89%; and the best ultra-white glass can only reach 89%. The light transmittance of acrylic is as high as 93%. Now many optical sights and high-precision optical lenses of cutting-edge weapons are made of acrylic. Acrylic is used in transparent swimming pools, aquariums, and aquarium projects. The transparent viewing surface is light and soft, and the visual effect is very gorgeous.

Third, acrylic also has good processing properties, can be machined and thermoformed, and can be seamlessly spliced on-site by injecting a special formula stock solution, which can meet the requirements of larger-size transparent whole panels and is not affected by transportation and space conditions. Tempered glass cannot be reprocessed, cut, or spliced. The maximum size of tempered glass from manufacturers can reach 6.8 m by 2.5 m. Because it cannot be seamlessly spliced, it cannot meet the requirements of larger-size transparent panels.
