Laminated glass is a type of safety glass that holds together when shattered. In the event of breaking, it is held in place by an interlayer or film, typically of polyvinyl butyral (PVB) or ethylene-vinyl acetate (EVA) or SGP film, between its two or more layers of glass. The interlayer keeps the layers of glass bonded even when broken, and its high strength prevents the glass from breaking up into large sharp pieces. This produces a characteristic "spider web" cracking pattern when the impact is not enough to completely pierce the glass. In the case of the EVA, the thermoset EVA, offers a complete bounding (cross-linking) with the material whether it is glass, polycarbonate, P.E.T. or other types products.
Laminated glass is normally used when there is a possibility of human impact or where the glass could fall if shattered and also for architectural applications. Skylight glazing and automobile windshields typically use laminated glass. In geographical areas requiring hurricane-resistant construction, laminated glass is often used in exterior storefronts, curtain walls and windows.
Laminated glass is also used to increase the sound insulation rating of a window, where it significantly improves sound attenuation compared to unlaminated glass panes of the same thickness. For this purpose a special "acoustic PVB" compound is used for the interlayer. In the case of the EVA material, no additional acoustic material is required, since the EVA provides sound insulation. An additional property of laminated glass for windows is that a PVB and SPG interlayer can block essentially most ultraviolet radiation. A thermoset EVA could block up to 99.9% of the UV rays.
Extremely high safety
The PVB or SGP interlayer withstands penetration from impact. Even if the glass cracks, splinters will adhere to the interlayer and not scatter. In comparison with other kinds of glass, laminated glass has much higher strength to resist shock, burglary, burst and bullets.
Energy-saving building materials PVB or SGP interlayer impedes the transmission of solar heat and reduces cooling loads.
Create aesthetic sense to buildings
Laminated glass with a tinted interlayer will beautify the buildings and harmonize their appearances with surrounding views which meet the demand of architects.
Sound control PVB interlayer is an effective absorber of sound.
The interlayer filters out ultraviolet rays and prevents the furniture and curtains from fading effects.
