Using a Tempered safety vacuum glazing system for your glazing application can provide you with a number of benefits. Aside from the aesthetic appeal of this type of glazing, you can also benefit from the fact that this type of glazing provides high impact strength and mechanical strength.
Asymmetric Double Glazing Improves Acoustic Attenuation
Increasing asymmetry in the glass panes can improve acoustic attenuation of insulated glazed units. These windows and doors can help to reduce noise by up to 32 db. These units are also available in a variety of different thicknesses. Thicker panes are better at reducing sound at low frequencies, while thinner panes are more effective at blocking noise at higher frequencies.
These asymmetric double glazed windows are ideal for housing near busy highways and construction projects. Generally, they will provide the best acoustic attenuation compared to other types of soundproofing. A single-chamber asymmetric unit can absorb 28 dB of noise, while a two-chamber asymmetric unit can absorb 40 db. Asymmetric laminated glass is also available. It consists of a third layer of glass that is different in thickness than the first and second layers. This layer faces the interior of the building and is sandwiched by a polyvinyl butyral film. The film provides acoustic attenuation by dissipating energy from the sound through vibration.
Mechanical Strength
Increasing the mechanical strength of Tempered safety vacuum glazing system by using extrinsic toughening mechanisms is a common approach. These include the introduction of compressive stress states on the outermost surfaces of the glass. In addition, the interior zone of the glazing develops compensating tensile stresses. The presence of mineral connections is important for effective toughening.
The goal of the study was to better understand the failure mechanism of VIG’s subjected to dynamic loads. This is done by measuring the surface stress of the glass after it has been impacted by a twin-tire pendulum impact test. The results were compared to numerical data of a monolithic glass pane. The simulated FTVG consisted of two 4 mm thick fully tempered glass sheets. A geometry model for one quarter of the FTVG is presented in Figure 9. The boundary conditions of ISO standard 10077-1 are applied.
Impact Toughness
Various glazing systems are available to architects and contractors for the purpose of reducing impact stresses. One type of glazing is tempered glass. This type of glazing has a higher thermal resistivity and impact performance than other types of safety glass. Another is laminated safety glass. This type of glass is constructed by bonding two panes of glass together with a plastic film. These panes can be made from tempered glass, standard glass or PVB.
Toughened glass is an alternative to tempered safety glass. It has a lower cost and offers the advantage of reduced weight. However, it is not as resistant to impacts as tempered glass. When broken, toughened glass tends to shatter into shards. This is because the glass is not reworked after toughening.
Hybrid Gas-VIG glazing System
During the last few decades, the Vacuum Insulating Glazing (VIG) technology has developed into a safe, thermally insulating glass, and is currently replacing gas filled IGUs in many new buildings. The technology is widely used in household appliances, transportation, and construction. It has been shown to outperform other insulating technologies in terms of its durability and thermal performance. It also outperforms existing insulating technologies in terms of weight and thickness.
The goal of VIG technology is to produce a thin profile, high strength vacuum double glazing with high thermal insulation. The first commercially produced VIG product was made by Nippon Sheet Glass, Japan, in 1996. Since then, considerable research has been conducted to further understand this technology. The International Standards Organization has also initiated an effort within the TC160 committee to develop standards for VIG.
Last Word
So, if you are buying vacuum glazing, compared to other insulating glass, tempered safety vacuum glazing systems offer more consistent and reliable performance. It also reduces the risk of injury during breakage.
