Laminated glass also possesses other unique properties, which make it an excellent product for commercial buildings. For instance, laminated glass provides the greatest reduction of ultraviolet (UV) light transmission of any commercial glass product available.

When combined with two layers of float glass, less than one percent of UV light is transmitted. This is important when considering the type of glass product to use in applications where UV protection is essential.

However, light and heat can also contribute to the fading of interior furnishings . It is important to consider using laminated glass products, which help to reduce visible light transmission and retain heat.

UV information provided by AIS Glass Solutions:

Laminated glass is a sandwich made of one piece of plastic Poly Vinyl Butyral between two or more glasses. The PVB sticks with the glass, forms chemical as well as mechanical bonds. When laminated with annealed glass, the layer maintains the geometric integrity of the pane in case of breakage. Also it gives acoustic insulation as well as gives protection against damage caused due to UV radiation because it cuts almost 99% of UV radiation present in the sunlight. A laminated glass is regarded as a safety glass by most of the standards.
