Due to widespread availability and low cost, Soda Lime Glass is most commonly used for picture framing glass. Glass thicknesses typically range from 1.8 to 2.5 millimetres (0.071 to 0.098 in). Clear glass has light transmission of approximately 90%, absorption of approximately 2%, and reflection of approximately 8%. Whereas absorption can be ...
In automobiles, the laminated glass panel is around 6.5 mm (0.26 inches) thick, in comparison to airplane glass being three times as thick. [21] In airliners on the front and side cockpit windows, there is often three plies of 4 mm toughened glass with 2.6 mm thick PVB between them.
The resulting glass code is the value of n d − 1 rounded to three digits, followed by V d rounded to three digits, with all decimal points ignored. For example, BK7 has n d = 1.5168 and V d = 64.17, giving a six-digit glass code of 517642. [1] Consequently, a linear approximation for the refractive index dispersion close that wavelength is ...
A typical installation of insulated glass windows with uPVC frames. Possibly the earliest use of double glazing was in Siberia, where it was observed by Henry Seebohm in 1877 as an established necessity in the Yeniseysk area where the bitterly cold winter temperatures regularly fall below -50° C, indicating how the concept may have started: [2]
Recycling codes are used to identify the materials out of which the item is made, to facilitate easier recycling process. The presence on an item of a recycling code, a chasing arrows logo, or a resin code , is not an automatic indicator that a material is recyclable; it is an explanation of what the item is made of.

In residential construction, thicknesses commonly used are 1 ⁄ 8 inch (3.2 mm) monolithic and 5 ⁄ 8 inch (16 mm) insulating glass. Glass may be used which is transparent, translucent, or opaque, or in varying degrees thereof. Transparent glass usually refers to vision glass in a curtain wall. Spandrel or vision glass may also contain ...
ICE 3 train with view into driver's cab ICE 3 train with glass panel switched to "frosted" mode. Eureka Tower in Melbourne has a glass cube which projects 3 m (10 ft) out from the building with visitors inside, suspended almost 300 m (984 ft) above the ground. When one enters, the glass is opaque as the cube moves out over the edge of the building.
