The interlayer is typically of polyvinyl butyral (PVB), ethylene-vinyl acetate (EVA), ionoplast polymers, cast in place (CIP) liquid resin, or thermoplastic polyurethane (TPU). [1] An additional property of laminated glass for windows is that an adequate TPU, PVB or EVA interlayer can block nearly all ultraviolet radiation.
In geographical areas requiring hurricane-resistant construction, laminated glass is often used in exterior storefronts, curtain walls and windows. The PVB interlayer also gives the glass a much higher sound insulation rating, due to the damping effect, and also blocks most of the incoming UV radiation (88% in window glass and 97.4% in ...
The PVB recycling process is a simple procedure of melting and reshaping it. One possible method of recycling of simple automotive laminated windshields could involve heating the windshield to above the melting point of the PVB interlayer and then separating the glass plies.
The market for laminated glass products is mature. With only minor modifications, the PVB interlayer sold today is essentially identical to the PVB sold 30 years ago. Since its introduction in 1938, the worldwide market for PVB interlayer has been dominated by a handful of large chemical companies.
The interlayer can also give the glass a higher sound insulation rating. There are several types of laminated glasses manufactured using different types of glass and interlayers which produce different results when broken. Laminated glass that is made up of annealed glass is normally used when safety is a concern, but tempering is not an option ...
It is the piece of glass opposite the windshield. Back glass is made from tempered glass, also known as safety glass, and when broken shatters into small, round pieces. [1] Windshields are made of laminated glass, which consists of two layers of glass, separated by a vinyl sheet. [2] Vehicle glass may contain heating coils or antennae. [3]
Other common names for it include "clear sight", "spin window", "Kent Screen" and "rotating windshield wiper". Clear view screens were patented in 1917 by Samuel Augustine de Normanville and Leslie Harcourt Kent as a stand-alone pillar-mounted screen, [ 1 ] with later patents for telescope and optics covers, followed by the more familiar ships ...
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 reduced by using low-iron glass, reflection can only be reduced by an anti-reflective surface treatment.
