PVB (Polyvinyl Butyral) Laminated safety glass makes it significantly more difficult for criminals to break through a shop front. It also prevents a simple fall against a large window from turning into a tragic accident. In addition to these well-proven safety and security benefits, laminated safety glass blocks noise and harmful UV radiation.
Laminated Safety Glass
Laminated glass is available in three performance variations:
1 Normal Strength (NS) for human impact safety (1 x 0.38mm PVB Interlayer)
2 High Penetration Resistant (HPR) for additional security (2 x 0.38mm PVB Interlayers)
3 High Impact (HI) for security in high-risk applications (4 x 0.38mm PVB Interlayers)
Laminated glass is tested by repeatedly dropping a 225g steel ball from a height of 9m. The impact of each drop is approximately the same as a blow from a hammer. The table shows the number of blows required to penetrate the glass.
Note: The size of the hole at penetration point is approximately 50mm in diameter. Many more blows are required to gain access.
The toughness and resilience of laminated glass makes it an excellent safety glazing material. In vertical or sloped applications, laminated glass can resist penetration from impact. If the glass is broken, fragments will adhere to the PVB interlayer, reducing the risk of personal injury and property damage.
Laminated glass offers greater protection for people and properties over other glass products. The standard two-ply construction provides resistance to penetration when subjected to attempted forced entry. In multiple configurations, laminated glass can even resist bullets, heavy objects, or small explosions.
The sound damping performance of the PVB makes laminated glass an effective sound control product. Laminated glass is commonly used in airports, museums, sound studios, and schools to reduce unwanted noise from airplanes, heavy machinery and traffic, to name a few.
SOLAR ENERGY PERFORMANCE
Laminated glass offers unique combinations of clear or tinted interlayers and solar heat reflecting coatings which can serve to reduce the harsh effects of glare and solar radiation to create comfortable conditions for the occupants of buildings.
The ultraviolet (UV) filtering performance of the polyvinyl butyral interlayer helps protect valuable furnishings, displays or merchandise from the fading effects of UV radiation.
NATURAL AND MAN MADE DISASTERS
Laminated glass can help provide protection from injury and property damage from man-made or natural disasters. By keeping the glass intact within the frame, laminated glass helps reduce injuries from large shards of flying glass caused by, for example hurricanes, earthquakes or other unusual loading on the glass.
LAMINATED PRODUCT RANGE
ColourVue™ laminated glass products are made from various combinations of clear and tinted glasses and PVB interlayer. ColourVue™ is available in a wide range of colours to meet a variety of aesthetic, glare reduction and solar control demands. Coloured and patterned interlayers can be used individually or in various combinations to create colourful and distinctive glass facades, partitions and interiors.
SolarVue™ provides medium solar control and a neutral, low reflective appearance in a range of colours. A thin deposit of nickel and chromium eliminates more than 55% of solar heat, while transmitting more than 45% of visible light. SolarVue™ also eliminates more than 99% of damaging UV radiation.
SolarShield® makes it possible to create attractive buildings with highly efficient solar control. The combination of a metallic coating and a clear or tinted PVB (polyvinyl butyral) interlayer is designed primarily to keep out as much of the sun’s heat as possible. In addition to reducing solar heat, SolarShield® also limits the amount of light entering the interior and blocks up to 99% of damaging UV radiation.
CoolVue® glass meets the growing demand for natural day lighting and building transparency, without the heat gain associated with ordinary clear glass. CoolVue® can transmit more than 70% of visible light while blocking more than 50% of solar heat.
E Range™ coated monolithic glass offers superior thermal insulation in standard frames designed for single glazing. E Range™ products reduce heating and air-conditioning costs by keeping more heat in during winter and blocking it out during summer.
Acoustic laminated safety glass is manufactured with a special vinyl interlayer that offers better sound control than traditional polyvinyl butyral (PVB) interlayers. The sound control rating of glass is expressed as a weighted sound reduction index (Rw) measured in decibels (dB).
