usually The Museum Glass Display case is selected laminated glass. The PVB interlayer in laminated glass will hold the glass together, protecting the exhibits inside. In addition, the PVB interlayer resists penetration or physical attack by forming a physical barrier against theft. Moreover, laminated glass can filter 99% of ultraviolet rays from the light outside showcases within a wave length of 280~380nm.
museum glass display cases glass types include:
common float glsss：
Float glass is a clear, distortion-free glass that can be supplied in a wide range of sizes and thicknesses to suit any flat glass application.
ti is a sheet of glass made by floating molten glass on a bed of molten metal, typically tin, although lead and other various low-melting-point alloys were used in the past.This method gives the sheet uniform thickness and very flat surfaces.
The extra clear glass is a type of float glass, which has very low iron content and hence is also called low iron glass. The iron content in float glass is usually 830 – 850 ppm (parts per million), while iron content in an extra clear glass is less than 150 ppm. It allows almost 92% of visible light to be transmitted. An extra clear glass is a colourless transparent glass and provides very clear view.
