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, typically of polyvinyl butyral (PVB) or ethylene-vinyl acetate (EVA), 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, PET, 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 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 EVA interlayer can block essentially most ultraviolet radiation. A thermoset EVA could block up to 99.9% of the UV rays.
Laminated glass is two or more panes of glass with one or more layers of polyvinyl butyral (PVB) sandwiched between them and treated. The glass panes can be basic float glass or tempered or heat strengthened panel. If the glass is broken, fragments tend to adhere to the PVB inter layer thereby reducing the risk injury from falling glass and helping to resist further impact or weather damage. It is most suitable wherever safety, security, noise control or UV control is a requirement. Glass can also be laminated with special PVB like – Coloured PVB in transparent, translucent and opaque, Acoustic PVB for improved acoustic performance and Sentry Glass for better structural strength.
Laminated glass doesn't shatter like ordinary glass. It absorbs impact, resists penetration and remains in glazing even if broken.
Laminated glass resists intrusion because the inter layer continues to safeguard the building even after the glass itself is broken.
Laminated glass is an excellent barrier to noise. The sheer damping performance of the plastic inter layer make the laminated glass an effective sound control product.
Laminated glass screens out 99% of the sun's damaging rays, protecting interior furnishing, displays or merchandise from fading effects of UV radiation.
Laminated glass remains in the frame and deter glass shards from flying.
