Laminated glass acoustic rating. Transforming glass since 1983.

Laminated glass acoustic rating Special acoustic grades of laminated glass are available, which comprises two glass sheets with a layer of acoustic resin. SoundPro calculates glass usage by performance or glazing configuration. Laminated glass will typically deliver better sound reduction properties than plain float or toughened glass. Various performances can be achieved by combing different types of glass thickness and number of interlayers. Its composition helps to reduce sound vibrations, improves STC ratings, and often is used in durable products, like Laminated Glass is a product that is formed by 2 or more pieces of glass that is then laminated together with PVB Interlayers. Guardian LamiGlass® Acoustic is a laminated glass with an advanced interlayer that delivers significantly improved sound Laminated IG (laminated glass toward interior) Double-laminated IG (various) Reports are generated in Eastman format and serve as guidance only. This ‘dip’ The performance data below applies to laminated glass units constructed with two plies of glass and an interlayer. The acoustic performance of glazing is -114• glass) with an STC rating of 34. The The software is able to calculate the the acoustic insulation provided by a particular glass type and configuration. To achieve this with a conventional double glazing width (about 28-35mm only) we have to employ an acoustics interlayer or a sort of resin between two panes in a laminate glass combined within a DGU. 52mm laminated glass is 39. The careful and considered selection of glass can be crucial in helping to reduce noise level and meet noise requirements. 500 630 800 1000 1250 1600 2000 2500. 3. This can then be used to select the correct glass for your requirements. Double Laminated Insulating Glass . Laminated & Double-Glazed Glass. Wired Glass – this is a type of safety and security glass due to the wire netting embedded within it during the A laminated glass of 2+2 mm reduces sound at high frequencies considerably more than a monolithic glass 4 mm-thick (that’s 8 to 10 dB of additional attenuation). A thicker interlayer than what is commonly used can also benefit Hermetically sealed IG units paired with laminated glass perform well in ASTM sound transmission ratings. 4mm Lam E: 16mm: 6. The interlayer also filters 99% of the UV light which can be the cause of faded Insulating Laminated Glass Construction. Compare this to a standard double glazed unit with two 4mm panes of glass and an air cavity, which will reduce ACOUSTA™ LAMINATED GLASS For more information refer to Acoustic Technical Information document.

Acoustic laminated glass. QLam Hush™ dampens noise providing enhanced sound insulation performance 12. Downloads: Product Data Sheet. SDAC™ Acoustic Control Glass. Acoustic glass is a little different than laminated glass. It can also improve energy efficiency Innovative acoustic interlayer for laminated glass. The difference is what you can't hear. 5 times When using insulating glass units, there are several options available, including increasing glass thickness; increasing the air space; evaluating different gas fills, spacers and sealant materials; and using different glass thicknesses for individual glass lites or a laminated component for one or both of the lites. When used in overhead or roof glazing, it provides insulation from rain impact noise. The desire for more natural light in buildings is driving a trend towards larger energy-efficient windows, and national and municipal level regulations require the use of safety glass in an increasing number of architectural applications, for which laminated glass is one of the most effective solutions. Glass surfaces are counted from the exterior face of the building. 24 Page 1 of 7 Due to continual product research and development, details listed are subject to change at any time.

Laminated glass is the next step up for acoustic control and delivers on all fronts, providing security, safety, noise dampening and UV protection. On the lower end of the spectrum, other acoustic glazing solutions will begin at around 36dB. DOUBLE LAMINATED INSULATING ACOUSTICAL DATA. Instead of the PVB interlayer, acoustic glass contains a special resin as an interlayer in between two sheets of glass. To illustrate, the STC value for a monolithic 6mm glass is 31, for an insulated 24mm glass is 35 and for a 13. Laminated glass increases the sound insulation by decoupling the glass panes and damping the vibrations generated by the sound waves.

That is why designers must look at other more effective options to improve the acoustical performance of window systems. 8MM ACOUSTIC LAMINATED Comprising of two or more panes of glass which are bonded together using a specially designed high performance clear PVB interlayer. Costing more than other materials, this is used mainly for exterior applications. Glass controls noise Laminated glass can increase an STC rating when cost and thermal insulation aren’t concerns. Options. While toughened, wired or patterned glass behaves acoustically the same as standard float glass, laminated glass reduces sound due to the vibration-dampening effect of the interlayer in-between. Cardinal's laminated glass offers sound dampening, reducing audio decibel levels in high-noise areas. 0 PVB (3. A typical dual-pane window has an STC rating of 25-30. The desired acoustic performance can be achieved through combining various thicknesses of glass with a special PVB (polyvinylbutyral) interlayer. gpd.
